RS Goes After TD for High-Closing

Tuesday, March 4th, 2008

In a developement that will bring tears of joy to (until recently?) Assiduous Reader madequota, Regulation Services has released a notice of hearing in a contested case against TD Securities and some of its traders.

The allegations against the individual traders may be summarized as:

During the relevant period, Nott, Sadeghi, Kaplan, Nemy and Poulstrup (collectively, the “Individual Respondents”) entered orders to purchase securities of one or more of African Copper PLC (“ACU”), Canaco Resources Inc. (“CAN.H” until May 26, 2005 while listed on the NEX and “CAN” as of May 27, 2005 while listed on the TSXV), Central Canada Foods Corporation (“CDF.A”), Peterborough Capital Corp. (“PEC”) and Titanium Corporation Inc. (“TIC”) without any intention that the orders would be executed and for no bona fide purpose. The Individual Respondents entered the orders with the intention of establishing a high closing bid price in order to improve the daily profit and loss position of the shares held in their inventory accounts, or to assist their colleagues improve their daily profit and loss position, and thereby to misrepresent the performance of the securities. The high closing bid prices were artificial in that they were not justified by any real demand for the securities. The high closing bid prices misrepresented the performance and actual demand for the securities to the market and to other market participants.

… while the allegation regarding TDSI is …

During the relevant period, TDSI failed to implement a trade supervision system that was adequate, taking into account its business and affairs, to ensure compliance with UMIR 2.2(2)(b). TDSI failed to ensure that the risks associated with proprietary trading by the Trade Execution Group (the “TEG”), and specifically the Burlington sub-branch, had been identified and that appropriate supervision practices and procedures to manage those risks had been implemented. As a result, TDSI failed to adequately review and monitor the Individual Respondents’ order entry activity and failed to detect or prevent the Individual Respondents from violating UMIR 2.2(2)(b).

The date of the hearing is yet to be determined. The Notice of Hearing, linked above provides the usual excruciating detail regarding the allegations.

Two of the traders were fired shortly after TDSI commenced its internal investigation of some of the actions at issue. There is some speculation that RS is trophy-hunting:

What’s got the Street’s attention is RS’s decision to go after TD Securities. “RS is trying to put a big trophy on the mantle by targeting the dealer, as well as the traders,” said a senior executive at a rival firm. Talk on trading desks is that TD Securities appeared to do everything right, by reporting a problem once supervisors realized what was taking place.

The danger of RS’s approach in going after TDSI is that it will simply encourage cover-ups. Whenever there’s a screw-up, the second guessing starts … I should have noticed this, I should have checked that, instead of sending a polite inquiry I should have stormed into his office and banged my fist on his desk. And I can assure everybody, RS included, that there will always be fault to find by somebody who wants to find it.

So … you’re a supervisor, you figure something may be happening that’s against the rules. What do you do? Do you actually investigate? If you find something and report it, RS will go after you for not finding it faster, fine you and possibly lift your license. Even if they don’t lift your license – even if they don’t go after you at all – your employer might fire you, just to make themselves look good (particularly if, as in the case of David Berry, they’re looking for an excuse anyway).

So … do you investigate thoroughly? Do you communicate your findings after a thorough investigation? Or do you just casually drift into the trading room and announce to nobody in particular that there’s some new procedures designed to catch some behaviour, to be put into effect next week?

The last option makes you, ethically if not legally, party to a cover-up. Which may, of course, be RS’s intention … if everybody’s guilty of something, then they have uncontrolled power to end careers at a whim. Then, finally, they’ll get some respect!

Quite frankly, high-closing isn’t a trading issue I get all that excited about – when the price of something gets high, I sell it. When the price gets low, I buy it. All this seems pretty simple to me. The high-closing / market manipulation rules are in place solely to protect the stupid, who would be much better off if they just got better investment advice.

I am much more annoyed with the RS restrictions on algorithmic trading which, in requiring algorithmic trading engines to be vetted by the executing broker, have a clear effect of stifling creativity, increasing the inefficiency of the market and encouraging high-closing. If I were to suspect high-closing on a particular issue I was watching, for instance, I could build an algorithm to jump on those bids within a second of order entry … and make the little snot pay through the nose for his temerity.

But then, that would leave RS with less to regulate …

RS Asserts Jurisdiction Over David Berry

Tuesday, March 4th, 2008

Regulation Services has released a decision regarding the challenge to its jurisdiction over David Berry. The hearing was reported on PrefBlog on December 12 … the upshot is:

We are therefore of the view that we have the necessary jurisdiction to hear and decide the case brought by RS against the Respondent. It follows that the Motion to Stay the proceedings should be, and hereby is, dismissed.

The next chronological step in this process is the OSC hearing on March 6, which has been brought by David Berry to obtain disclosure of materials relating to the RS investigation of the affair and the RS settlements with Scotia and Marc McQuillen. The OSC is being appealed to after a denial of such disclosure by a Regulation Services panel.

Cost of Regulation : Maple Bonds

Saturday, March 1st, 2008

Maple Bonds are wonderful things! Portfolios can be diversified and, given current conditions, institutional investors can take advantage of some of the greatly elevated yields on US Financials without taking on currency risk.

This post, however, is due to a paragraph in an IIAC review of the Maple market:

Costs still need to come down

Having to possibly deal with legislation and regulation in 13 different jurisdictions can dissuade distribution in some provinces and territories and disadvantage investors. Regulatory fees range from $0 in Prince Edward Island to flat fees of up to $500 in Ontario to fees of three basis points of face value in British Columbia. For example, $100 million in Maple bonds distributed to B.C. residents adds $30,000 to all-in costs; distribution of $100 million to Quebec or Alberta investors adds a further $25,000 per province to issuer expenses for little or no work by the regulators. Market-watchers are concerned that the differences in registration fees could distort efficient distribution of the securities or – worse – make it uneconomical for issuers to issue in parts of Canada at all.

The IIAC has written to the Canadian Securities Administrators (CSA) asking them to extend the passport framework as part of Passport 2 to exempt market instruments, including Maple bonds. For exempt issuances, the IIAC asked the CSA to allow a simple single form filing with a lead regulator and payment of a single low flat, rather than ad valorem, fee to promote national distribution. This would also help CSA members meet their common goal of fostering fair, efficient and transparent capital markets for investors.

What would be really nice would be if the materials relevant to each issue were centrally published via a SEDAR-like facility. There is, for example, a Lehman Brothers issue in which I am interested, but the lead manager is of the view that showing the offering documents to anybody other than a primary purchaser is illegal, since it’s a private placement. The details are on Bloomberg, right? And due-diligence consists of looking at Bloomberg, right? Idiots.

Icebergs, Retail & RS

Friday, February 22nd, 2008

Assiduous Reader madequota told me in a comment that:

I’ve mentioned the other cloaking device they use as well, the so-called ‘ice-berg” order. Can I strategically advance my cause as a retail investor by using icebergs? NO. Can I mislead other investors by coming into the market anonymously? NO. Does Regulation Services see a conflict in this? NO.

and later that

I’ve dealt with a number of different brokers, and all confirm that “iceberg” orders, and the option of listing orders under broker 1 are institution-only tools, and Regulation Services is the body that is responsible for this. Perhaps the people I have spoken too were misinformed, but they are consistent in their explanations, so I tend to buy into it.

OK … I’ve been in the business for a while. On the inside, and I’ve occasionally had to get the absolute truth of some matter or other. I have learned one thing: Don’t Trust What Anybody Claims About The Rules.

Company policy, tradition and wild guesses will often be confused with The Rules. This applies to operations personnel, traders, compliance people … anybody.

So I asked the horse’s mouth:

I have been advised that retail clients are not permitted to enter iceberg orders on the TSX due to rulings of Regulation Services.

Can you confirm this? Are there any documents on your website pertinent to the discussion or communication of such a ruling?

Here’s how Regulation Services responded to my query:

Thank you for your email inquiring about Iceberg orders and retail clients.

Market Regulation Services Inc. (RS) is not aware of any such restriction. UMIR 6.3 Exposure of Client Orders requires a client order that is less than 50 Standard Trading Units and less than $100,000 value to be immediately disclosed.  There is an exception to that rule that if the client requests that the order not be fully disclosed then the rule does
not apply.

Here is a link to UMIR 6.3. I suggest that clients of discount brokerages should write letters to the Big Bosses of these brokerages politely asking for the capability to be added to the software.

Update: “Wait a minute!” mutters the baffled crowd “What’s an iceberg order?”

They were introduced on the TSX in 2002:

Using compliant access technology provided by one of the Toronto Stock Exchange’s and TSX Venture Exchange’s Order Access Partners, a Participating Organization or Member may enter a large order of several thousand shares, but describe a “disclosed” portion, which may be as few as 2,000 shares. Those disclosed shares will be displayed to traders and the public, but all shares, up to the entire balance, are eligible to trade at any time – albeit after any and all disclosed volume at the same price.

If the Iceberg order is filled in portions, its disclosed portion, which fills first because of its disclosure, may eventually be decremented to zero. At this point, the displayed portion of the Iceberg order will automatically refresh to the original disclosed amount, repeating as necessary until the entire balance is traded. When an Iceberg order refreshes, it receives a new time-stamp, allowing other same-price orders an opportunity to move up in the time queue.

You would use them, for instance, if you wanted to sell 20,000 preferred shares and couldn’t find a block buyer (or didn’t want to ask around, for fear of moving the price). If you put in an order to sell the whole block at 21.50 as a regular order, you’d probably scare away the bids … with that kind of size overhanging the market, many traders will figure the market’s going to move down. And maybe they’ll back off on what bids they do have, hoping that you’ll get desperate.

So with an iceberg, you can just show it 2,000 at a time. Assuming that it’s just a straight sell – nothing to be done on the other side – this would be (slightly) superior to instructing a more complex algorithmic software package to do the same thing. Algorithmic software does have a latency factor … trade #1 would get filled, the TSX would notify the seller’s machine, the software figures out it has to put in another order, it transmits it, the order is checked and accepted by the TSX and then gets displayed. This doesn’t take much time, but it does take some time. If somebody had put in, say a market order to buy 5,000 shares, you would miss the last 3,000 of them, which would get filled at prices worse than yours before you’d even received notification of your fill!

And, of course, doing it manually will take even longer than software, by orders of magnitude.

Update, 2008-7-16 The minimum show for an iceberg is the greater of 500 shares or the Minimum Guaranteed Fill.

A Better Credit Rating Solution?

Friday, February 15th, 2008

Christopher Cox, Chairman of the SEC was criticized in PrefBlog on February 8 for his apparent belief that what this world needs is more rules.

I was very happy to be alerted by Naked Capitalism to some remarks he has made that show a better appreciation of the problem:

So how would the SEC substitute — and diminish — the regulatory reliance on ratings?

Mr. Cox said “one means of substituting … would be to substitute the current definition of the rating currently provided by the rating itself.”

What that means is that the SEC is considering ways of setting criteria that gets away from the ratings but focuses instead on the underlying concept. For example, for some rules the SEC could require bonds to be liquid and then develop some measure by which to sort them other than a credit rating, says one person familiar with the matter.

I posted yesterday in Earth to Regulators: Keep Out! that there wasn’t much point in regulation. All the rules in the world won’t make anybody a better analyst … or, indeed, to avoid blow-ups of any kind in this uncertain world.

The problem the regulators face is that under Basel II there is a good chance that a pro-cyclical bias will be introduced to bank capital requirements:

Under Basel II, the capital requirements for the largest banks would be based on their current assessment of the probability of default of the borrower (ie rating) – Basel Committee of Banking Supervision (2003). There is a live policy debate over whether different rating approaches adopted by the banks would lead to different procyclical outcomes and if they did which approach banks would choose to adopt. We find that less forward-looking bank rating systems, conditioned on the point in the economic cycle, could lead to a substantial increase in capital requirements in recessions. Looking at the 1990–1992 recession, ratings based on a Merton-type model, which reflect the point in the cycle through the use of current liabilities, lead to a 40% to 50% increase in capital requirements. In contrast, Moody’s ratings which are more forward looking, lead to little increase in capital requirements.

The new Accord which will be introduced in 2006 could, however, have a profound effect on the dynamics of bank minimum capital and lending in recessions. In contrast to the current Accord where, for a given quantum of lending to a particular set of borrowers, the capital requirement is invariant over time, under the new Accord the capital requirements will depend on the current assessment of the probability of default (PD) of those borrowers. If borrowers are downgraded by a bank in a recession, then the capital requirements faced by the bank will rise. This would be in addition to the possible reduction in the bank’s capital because of write-offs and specific provisions.

It’s amusing that the authors (Eva Catarineu-Rabell, Patricia Jackson and Dimitrios P. Tsomocos) of the quoted paper prefer the Ratings Agency style of attempting to rate “through the cycle” as opposed to the more dynamic Merton-style approach, but that’s beside the point for now.

There is only on legitimate reason that Credit Ratings might be of importance to regulators of any kind: the effect on bank capital requirements. And it should be noted that the only reason they have any effect on bank capital requirements is because the concept was written into the Basel Accords. And, of course, they were written into the Basel Accords because of the superb track-record (remember that concept? track record?) of the Credit Rating Agencies.

Not perfect, by any means. There are big blow-ups and minor whoopsees, but it’s an uncertain world dominated by human frailty. Get used to it.

So, I suggest, if the regulators wish to improve their legitimate regulation via new and improved credit ratings, it is only right and proper that they do it themselves, rather than imposed ludicrous constraints and requirements on private businesses in a horrific central planning exercise. Cox is on the right track.

Naked Capitalism takes a very dim view of the remarks:

Require bonds to be liquid?. That is the most deranged thing I have heard in a very long time, and this presumably coms from someone within the US’s top securities regulator. It confirms what I have long suspected: that the SEC is preoccupied with the equity market and knows perilous little about debt.

A simple illustration: just about all corporate bonds are illiquid. That’s one reason credit default swaps are popular. Investors can use CDS to create synthetic corporate bond exposures, which unlike the underlying bonds, can be readily traded. But Cox would have us write off the corporate bond market.

Corporate bonds are illiquid relative to, say, stocks. Sure. I discussed this on November 19, in relation to Prof. Cecchetti‘s desire to have all financial instruments traded on an exchange:

Looking at the topography of the financial system, we see several immediate candidates for migration to exchange trading.  I will mention two:  (1) bonds and commercial paper, and other fixed income securities; and (2) interest-rate swaps and other derivatives that are traded in large volume. Bonds as we know them have been around since at least 16th century.  And the quantities outstanding are substantial – in the United States there something like 4000 distinct corporate bond issues with a market value of roughly $10 trillion.  I can see no reason that these “fixed-income” instruments are not traded on an exchange.

How can we encourage the movement of mature securities onto exchanges?  The answer is through a combination of information and regulation.  On the information side, it is important that less-sophisticated investors realise the importance of sticking with exchange-traded products.  The treasurer who manages the short-term cash balances for a small-town government should not be willing to purchase commercial paper, or any security, that is not exchange traded.

However … there are degrees of illiquidity! Assiduous Readers of PrefBlog will be very familiar with the idea that, while the average trading value (however calculated!) of a particular preferred share might be only $100,000, it is generally possible (for MOST issues, MOST of the time) to call a dealer and trade a block worth $10-million … maybe not right away, but, say, within a week.

So, subject to problems with measurement and control that must be addressed, I’m entirely comfortable with the SEC (or other regulators) coming up with some kind of way in which liquidity will be measured and applying some kind of concentration penalty on banks who hold a position that is too large to be regarded as liquid. This would be a little easier in the case of the States, which already has the NASD TRACE system in place.

There is also the potential for so-called liquidity guarantees to be put in place at time of underwriting. So-called? Well, the European Covered Bond market association called for suspension of the agreement on November 21 and there are current problems with liquidity on Auction Rate Municipals, as mentioned yesterday. I’ve mentioned my own problems in not being able to get a bid for less than a million of good quality corporate paper. So, while I would not put too much faith in the ability of the private sector to provide a bottomless pit of liquidity for bonds in general, liquidity could be enhanced … central banks, for instance, could enter into “liquidity provider of last resort” agreements and accept corporate and other bonds as collateral on a routine basis.

I would not advocate formal liquidity guarantees. It’s too much central bank intervention in the economy … in times of stress, the private sector just ain’t gonna want to take long term debt onto its books, especially not if it’s esoteric. But liquidity could be measured and a capital penalty applied to instruments whose liquidity in times of stress was feared to be sub-normal. 

I’m not sure that I agree with Naked Capitalism‘s point about CDSs. They are sometimes more liquid, sure – it’s a lot easier to go long a CDS than it is to short a corporate bond, especially in size. But as I see it, the main attraction of CDSs has been that they make it a lot easier to lever up a portfolio, compared with taking a cash position (long or short) and (financing or borrowing it). That’s related to liquidity, but is not exactly liquidity.

The guts of the problem, however, is step 2 of Mr. Cox’s idea: and then develop some measure by which to sort them other than a credit rating.

Market prices won’t do it. I’ve posted elsewhere about market implied ratings and how dubious I am that such a system will prove to be a better indicator of credit quality than what we already have. The Fed is dubious too!

And, as noted, structural models such as Merton’s (equity implied ratings were briefly mentioned on October 18) (a) have a lot of problems, and (b) are pro-cyclical.

I’ve also noted that any quantitative system performs badly at trend changes … and it is at precisely the time of trend changes that stresses on the financial system become pronounced.

So what’s the Fed to do? The only answer is … if they want to come up with some way of defining credit risk, they’ll have to set up their own in-house credit rating service. Good luck with that!

Earth to Regulators: Keep Out!

Thursday, February 14th, 2008

Willem Buiter’s excellent blog, Maverecon, brings to my attention two reports prepared in the UK:

Willem Buiter is frequently mentioned in PrefBlog: he has, for example, prepared a very good summary of Lessons from the 2007 Financial Crisis. I sharply disagreed with his prescription for reform of the Credit Rating Agencies and also with his current statement:

The Report also mentions the need to improve the functioning of securitisation markets, including improvements in valuation and credit rating agencies but offers very little beef in these areas. It is clear that the credit rating agencies will have to be ‘unbundled’, and that the same legal entity should not be able to sell both ratings and advice on how to structure instruments to get a good rating. The conflict of interest is just too naked. Rating agencies will have to become single-product firms, selling just ratings.

… but for now I’ll let that go. In this post I will discuss the Official Position.

Section 2.61 of the Financial Stability report states:

The Authorities believe that the preferred approach to tackling such issues is through market action, and where appropriate through changes to the IOSCO Code of Conduct on Credit Rating Agencies. However, it is important to recognise that prudential credit ratings are a regulatory tool, in that supervision within the CRD/Basel II framework places reliance on the use of rating opinions to determine risk weightings for capital purposes. Therefore regulators have a strong interest in ensuring that ratings are viewed as reliable and that the information content of ratings is sufficient. If the issues summarised above are not adequately addressed by the markets, alternative measures to remedy these issues should be considered.

… while Section 2.62 continues:

Investors also need to learn lessons from recent events. In particular, investors need to develop a more sophisticated use of ratings. Market participants that consider investing in new asset classes, such as structured products, should not use ratings as a substitute for appropriate levels of due diligence, nor draw – potentially misplaced – inferences from ratings that the behaviour of structured securities share the same characteristics, including liquidity characteristics, as more familiar comparably-rated corporate securities. Recent losses and illiquidity in such asset classes have ensured these issues are in the forefront of investors’ minds, and market practice is already adapting rapidly in response. There will be a role for coordinating bodies – such as industry groups and international fora – in clarifying and codifying new practice.

And, finally, I note that the authorities are requesting, inter alia, the following feedback:

2.6) Have the Authorities correctly identified the issues on which international work on credit rating agencies should focus?

2.7) Do you agree with the Authorities’ proposals to improve the information content of credit ratings?

2.8) Do you agree with the Authorities that the preferred approach to restoring confidence in ratings of structured products is through market action and, where appropriate, changes to the IOSCO Code of Conduct on Credit Rating Agencies?

First, let’s look at a little history. Remember the Panic of 1825? I will remind Assiduous But Sometimes Forgetful Readers of the bailout of the banking house of Sir Peter Pole, as related and analyzed by Larry Neal, professor of economics at the University of Illinois at Urbana-Champaign:

The first mention of the crisis occurs on December 8, 1825, when “The Governor [Cornelius Buller] acquainted the Court that he had with the concurrence of the Deputy Governor [John Baker Richards] and several of the Committee of Treasury afforded assistance to the banking house of Sir Peter Pole, etc.”44 This episode is described in vivid detail by the sister of Henry Thornton Jr., the active partner of Pole, Thornton & Co. at the time. On the previous Saturday, the governor and deputy governor counted out £400,000 in bills personally to Henry Thornton, Jr., at the Bank without any clerks present.45 All this was done to keep it secret so that other large London banks would not press their claims as well. A responsible lender of last resort would have publicized the cash infusion to reassure the public in general. Instead, the run on Pole & Thornton continued unabated, causing the company to fail by the end of the week. Then the deluge of demands for advances by other banks overwhelmed the Bank’s Drawing Office.

The analysis makes perfect sense to me. The lender of last resort should enjoy the utmost confidence of the investing public, with an unparalleled reputation for probity and bottomless pockets.

However, the Treasury Committee report on Northern Rock referenced above provides extensive detail about the urge of the lender of last resort to provide covert assistance only and why it was finally decided that any support had to be made public (paragraphs 123-142, inclusive). Paragraph 165 states as a conclusion of the committee:

We accept that the consequences of an announcement of the Bank of England’s support operation for Northern Rock were unpredictable. There was a reasonable prospect that the announcement would have reassured depositors rather than having the opposite effect, particularly prior to the premature disclosure of the operation. However, after the premature disclosure of the support, and against the background of the market reaction to Barclays use of lending a fortnight earlier, it seems surprising that the issues were not urgently revisited. It is unacceptable, that the terms of the guarantee to depositors had not been agreed in advance in order to allow a timely announcement in the event of an adverse reaction to the Bank of England support facility.

In this case it was the announcement that the Lender of Last Resort had been called upon that actually caused the run.

I will also note the acknowledgement of Prof. Buiter in Paragraph 164:

Professor Buiter took a rather different view:

If [the Tripartite authorities] were not quite convinced that the public would believe them—and in these days you cannot be sure of that—then the immediate creation of a deposit insurance scheme that actually works and is credible would have been desirable. To wait three days was again an unnecessary delay.

In other words, there is good agreement that the authorities have squandered the trust of the public. The quote seems to have been lost in a revision, but I recall reading at the time that one woman queuing up for her money at a Northern Rock branch told a reporter at the time – who was puzzled as to why she was concerned – that ‘they lied to us about Iraq. Why shouldn’t they lie to us now?’

My thesis can be stated very simply: given that distrust of regulatory and other official bodies is so deeply ingrained into the public psyche, how can there be any contemplation of the idea that increased regulation and official oversight of the Credit Rating Agencies will improve public trust in the ratings?

The proponents of increased regulation also appear to be completely unable to provide any evidence that a credit rating analyst required to fill in forms and tick off boxes will provide estimates and advice that are any better than he would have produced without filling in forms and ticking off boxes.

Sadly however, those investment advisors, both licensed and unlicenced, who persuaded clients/employers/investors that the ability to write a big cheque equated to investment management skill desperately need someone to blame, now that their delusions have blown up in their clients faces. There is also pressure from subscription-based agencies for the regulators to get them more clients. And, of course, the supreme test of one’s ability as a regulator is total faith in the proposition that everything be regulated by a wise regulator.

So … there’ll be changes, for sure. Mostly cosmetic, assuredly costly, definitely useless. But after all, nobody must ever lose money on an investment, or take responsibility for their own actions, right?

And, sadly, once any plan is implemented it will meet its unstated purpose of creating a well-defined scapegoat for any blow-up. As Scotia is proving in the course of its battle with David Berry: if you want to get somebody, and are prepared to spend enough money on enough lawyers to check through things carefully enough, you can “get” anybody … and pretend to be shocked at what you’ve found.

Willem Buiter's Prescription

Friday, December 21st, 2007

Willem Buiter of the London School of Economics has authored Lessons from the 2007 Financial Crisis, published by the Centre for Economic Policy Research.

The paper includes one thoroughly delicious quote that shows the author understands the nature of regulation:

Because Sarbanes-Oxley compliance is mainly a matter of box-ticking (like most realworld compliance, especially compliance originating in the USA), it has not materially improved the informational value of accounting or the protection offered to investors.

All in all, the essay is extremely good … I may not agree with all of it, but the man makes some good points and has some well-founded opinions. I’ll present some quotes from the essay with my own thoughts … but the full document is well worth reading.

There is a long section on the credit rating agencies. Mr. Buiter states as problems:

  • Any model of credit risk will have flaws and these flaws may be exploited by issuers. Even honest models won’t work particularly well during black swan events.
  • Only default risk is rated – not market risk and not liquidity risk
  • agencies are conflicted, in that:
    • they are paid by the issuers
    • they sell advisory services to their rating service clients
    • the complexity of some instruments results in designer and issuer working with the same model … possibly one designed by the issuer

To Mr. Buiter’s credit, he does not attempt to solve the first two problems with rhetoric:

There is no obvious solution other than ‘try harder and don’t pretend to know more than you know’ for the first problem. The second problem requires better education of the investing public.

His third problem, which has three facets, has a five part solution:

  • Reputational concerns
  • Remove the CRA’s quasi-regulatory role
  • Make the CRAs one-product firms
  • End payment by issuer
  • Increase competition

I don’t have a major problem with the idea of removing the CRAs’ quasi-regulatory role (their ratings are a factor in determining the credit conversion factor that converts the total value of the loan to risk-weighted assets), but Mr. Buiter is not clear on what is to replace the current system.

It seems clear that a loan to IBM is safer than a loan to Joe’s Barbershop; it also seems clear that this difference should have an effect on the measured risk profile of the bank. I suggest that the CRAs have a very good track record in assessing these risks – and yes, I am including the subprime & Enron debacles when reviewing their record.

The thing about risk, you see, is that it’s risky.

With respect to his third proposition, making the CRAs one-product firms … how is he going to enforce this and why would he want to? Yesterday we saw extremely poor performance by the CIBC preferred issues. I will suggest that some portion of this, at least, was due to stockbrokers telling their clients that CIBC was a relatively poor credit (relative to other banks, and relative to their financial position last year at this time) and exposure to it should be minimized. In such a case, the stockbroker is acting as a Credit Rating Agency.

In the absence of a regulatory role for CRAs, how is one to differentiate between a one-product-by-regulation firm and … anybody else?

His proposal for ending issuer payment is so convoluted I will reproduce it in full, to avoid charges of mockery by misquotation:

Payment by the buyer (the investors) is desirable but subject to a ‘collective action’ or ‘free rider’ problem. One solution would be to have the ratings paid for by a representative body for the (corporate) investor side of the market. This could be financed through a levy on the firms in the industry. Paying the levy could be made mandatory for all firms in a regulated industry. Conceivably, the security issuers could also be asked to contribute. Conflict of interest is avoided as long as no individual issuer pays for his own ratings. This would leave some free rider problems, but should permit a less perverse incentivised rating process to get off the ground. I don’t think it would be necessary (or even make sense) to socialise the rating process, say by creating a state-financed (or even industryfinanced) body with official and exclusive powers to provide the ratings.

Frankly, I don’t understand why his proposed solution, involving mandatory payments by firms in the industry, is different from the socialization he decries. There may also be some conflict with his proposal to emphasize reputational concerns and competition … how do I go about getting some of the lolly? Can I just declare to the central body that I am a credit rater, that will be $500,000 please?

Reputational concerns and competition currently work along the lines of … some firms are better regarded by investors than others. I, for instance, have greater respect for Fitch and Moody’s than for S&P and DBRS … give me my choice of any two ratings on a bond, and you know which ones I’ll pay attention to! How would this be reflected in such a centralized system?

In the end, I have to reiterate my familiar refrain: Credit Ratings are Advice. Take it, leave it, your choice. So far, the Bank of Canada has said it best:

investors should not lose sight of the fact that one can delegate tasks but not accountability.

After reviewing the macroeconomic situation he makes further proposals, including:

if a financial institution borrows short and lends long, if it borrows liquid (during normal times, but with the risk of occasional illiquidity in its usual funding channels) and lends illiquid, and if banks are substantially exposed to it, then it should be regulated like a bank, even if it says ‘Hedge Fund’ on the letterhead. The rules should aggressively chase the unceasing attempts, through institutional and instrument innovation, to avoid regulation.

I disagree with this, particularly with the implicit belief that rules exist in order that they be followed. The weak point of the argument here is “if banks are substantially exposed to it“. It does seem likely that there has been far too much contagion in the past crisis, but regulating the universe is not the proper answer. What should be done is to improve the capital requirement rules and force the banks to make a more substantial capital provision for their riskier assets – such as Mr. Buiter implies is a good description for their hedge fund exposure.

If the risk weights applied to, for instance, the provision of a global liquidity line to a SIV have been shown to be inadequate (and this has not been documented, although I suspect that it is the case) … increase the risk weight of the line! Currently it’s at a flat 10% … I suggest that a tiering be considered, so that a bank with $10-billion of tier 1 capital can extend such a line for $10-billion at the 10% rate, but the next ten billion is charged at a 20% rate, etc.

Ensuring that everything is regulated is poor policy. Let us ensure that the core of the financial system – the banks, who have access to lines provided by the central banks – is secure, and then let people play around on the edges to their, and their investors’, hearts’ content.

The main problem with the arrangement [separating bank supervision functions from liquidity provision functions] is that it puts the information about individual banks in a different agency (the FSA) from the agency with the liquid financial resources to provide short-term assistance to a troubled bank (the Bank of England). This happened when the Bank lost banking sector supervision and regulatory responsibility on being made operationally independent for monetary policy by Gordon Brown in 1997. It’s clear this separation of information and resources does not work.

This issue was discussed on December 5.

Liquidity can vanish today, because market participants with surplus liquidity fear that both they themselves and their potential counterparties will be illiquid in the future (say, three months from now), when the loans would have to be repaid. A credible commitment by the Central Bank to provide liquidity in the future (three months from now) would solve the problem, but it is apparent that the required credibility simply does not exist. Therefore, the only time-consistent solution, in the absence of a credible commitment mechanism, is to intervene today at a three-month maturity.

One lesson – that Canadian non-bank ABCP investors will be happy to explain thoroughly – from the current crisis is that liquidity risk is different from credit risk. Traditionally, LIBOR spreads are explained in terms of credit risk – I suggest that liquidity risk is the operational concern and that liquidity hoarding is its sympton. I remember on anecdote from the Panic of 1907 … a banker complained to J.P. Morgan that his liquid assets had been eroded to 18% … Morgan gave him the what-for, telling him that liquid assets were held precisely for such circumstances.

If a bank’s afraid to make three-month interbank loans because it might have its credit lines drawn on in the intervening time, then part of the problem is that it has too many lines – a problem that would be addressed by higher capital charges.

To address the point, however, I have no problem with, for instance, a regular three month term facility, to be financed with treasury bills as a neutralizer.

Capitalism, based on greed, private property rights and decentralised decision making, is both cyclical and subject to bouts of financial manic-depressive illness. There is no economy-wide auctioneer, no enforcer of systemic ‘transversality conditions’ to rule out periodic explosive bubble behaviour of asset prices in speculative
markets. It’s unfortunate, but we have to live with it. The last time humanity tried to do away with these excesses of capitalism, we got central planning, and we all know now how well that worked. Hayek and Keynes were both right.

Hear, hear!

All in all, a fine article.

Bank of Canada Discusses Credit Rating Agencies

Thursday, December 6th, 2007

The Bank of Canada has released the December 2007 Financial System Review (link broken. Click HERE to find the article discussed … JH 23-10-13) which includes a review of the Credit Rating Agency issue by Mark Zelmer, the Director of the Financial Risk Office.

Frankly, it’s a bit wishy-washy, but does summarize the various issues in a well-structured manner. Mr. Zelmer concludes:

In the end though, investors need to accept responsibility for managing credit risk in their portfolios. While complex instruments such as structured products enhance the benefits to be gained from relying on credit ratings, investors should not lose sight of the fact that one can delegate tasks but not accountability. Suggestions such as rating structured products on a different rating scale could be helpful, in that this may encourage investors to think twice before investing in such complex instruments. Nevertheless, investors still need to understand the products they invest in, so that they can critically review the credit opinions provided by the rating agencies.

Where Did the Risk Go? – An Early Attack on the Ratings Agencies

Tuesday, November 6th, 2007

I’ve run across an extremely interesting paper, Where Did the Risk Go? How Misapplied Bond Ratings Cause Mortgage Backed Securities and Collateralized Debt Obligation Market Disruptions, written by Joseph R. Mason, an associate professor at Drexel University who has been mentioned here before in connection with his testimony to Congress, and Joshua Rosner, Managing Director of Graham Fisher & Company, a firm that provides “Independent research for institutional investors in financial service assets”.

The primary recommendation for public policy is:

Significant increases in public access to performance reports, CDO and RMBS product standardization, and CDO and RMBS securities ownership registration can help decrease the existing over-reliance on ratings agency inputs to rate and ultimately value the securities and reducing the valuation errors inherent in “marked-to-model” (rather than marked-to-market) portfolios. SEC Regulation AB was a (late) start for ABS and RMBS. Overall, however, the U.S. economy needs an efficient public CDO market that allows transparent openmarket pricing of market risk and outside research into new securities and funding arrangements.

This is a principle with which I can whole-heartedly agree … although I will not guarantee  sweet accord when the details are hammered out! There should be no regulatory restrictions on the flow of information … it should be possible to publish all deal information without fear of adverse regulatory repercussions, but there is often some confusion on this point. The regulators should first make it plain that, while selling the investment to a non-qualified investor may be improper, publishing the advice is encouraged.

After that, let the market and the Prudent Man Rule do its work. I think it would be fairly easy to argue that a Prudent Man would review available information prior to making an investment. At which point we get into further problems … how much review is enough?

Consider a plain and ordinary S&P 500 Index Fund. How much of the fund material do you have to read before you can purchase some on behalf of a client? Do you have to read through and understand the annual reports of all 500 companies?

I suggest that the archetypal Prudent Man need only

  • understand what the S&P 500 is attempting to do, and
  • verify that the vehicle will track it ‘reasonably’ well, and
  • do so at a realistic cost

… but there will be legitimate disagreement over even this simple exposition! My continued vocal support for the primacy of the Prudent Man Rule should not be taken to imply that I believe it will be simple and unambiguous.

Bank of England Discusses Role of Credit Rating Agencies

Thursday, October 25th, 2007

Geez, I was just locking up when I saw a story on Bloomberg – BOE Says Intervention May Be Required Over Credit Ratings. The third paragraph is considerably less emphatic than the first:

Credit-rating firms should face “public sector intervention” if they don’t overhaul the way they grade so-called structured debt products and provide more information to investors, the Bank of England said.

“These actions might occur voluntarily in the light of recent market experience,” the Bank of England said in the report. “Without this market evolution, there might be a case for public sector intervention to specify and encourage higher and common standards of assessment and disclosure.”

The BoE news release doesn’t mention the agencies; but I’ll include some quick snippets from the actual report:

Some end-investors and fund managers may have mistakenly assumed that the credit ratings of these products provided information on other risks. Many of these instruments are ‘buyand hold’ securities for which there is not always a readily available secondary market. A single rating does not capture adequately all of the risks inherent in these products — for example, liquidity risk — as reflected in the differential pricing of products within a similar ratings band.

The controversial stuff is in box 6 on page 56 of the report. Five suggestions for possible improvements are made – and I’m not going to comment on them now. However, these suggestions are inspired by a false premise:

These suggestions aim to facilitate a more sophisticated use of credit ratings by investors.

To which – as one last sally before switching off – I’ll say:

  • If a more sophisticated use of credit ratings by investors is desired, then it would appear more appropriate to concentrate any regulatory action on such investors. Yank a few licenses for imprudent conduct such as unsophisticated use of credit ratings, for instance. Make it clear that CEO’s who play at being Portfolio Managers with shareholder money are civilly liable if found negligent or reckless.
  • investors – taken as a group, with plenty of exceptions – do not want to use credit ratings in a more sophisticated way. They want one number that doesn’t need to be thought about in order to offload their responsibilities

Update, 2007-10-25: I must admit to some confusion regarding one of the Bank’s recommendations:

In moving forward, there are several areas in which further work is needed by market participants and the authorities in the United Kingdom and internationally to restore confidence in the financial system

The smooth functioning of markets in complex instruments depends on clarity about their content and construction. As discussed in Box 6 on page 56, rating agencies should support this process by clarifying the information available to investors on the risks inherent in products and the uncertainties around their ratings assessments. Recent events have demonstrated to investors the dangers of using ratings as a mechanical input to their risk assessment.

Why is it the ratings agencies’ job to clarify “the information available to investors on the risks inherent in products”? Just coming up with an assessment of credit risk is a pretty big job, and quite enough for one army of specialists. There is a very real danger here that the current fad for blaming the ratings agencies will lead to a situation in which they are held accountable for making market recommendations. That’s the job of investors! And if there are “risks inherent in products”, these are supposed to be disclosed in the prospectus – you know, around page 400, along with risks of meteorites wiping out head office.

Fans of the Black Swan model of Nassim Taleb will be gratified by the Bank’s note that:

It is striking that a market as small as US sub-prime RMBS, with a size of around $700 billion, had such pervasive effects on much deeper and more liquid markets, such as the asset-backed securities (ABS) markets (with a size of $10.7 trillion).

I prefer to think of financial markets as a chaotic system … which might be criticized as mere definitional quibbling, but even fat-tailed distributions strike me as being too deterministic. The universe is an unfriendly place; there is no telling which part of it is going to swoop down and kick you next.

Update, 2007-10-26: I became so interested in Box 2 of the report, Valuing sub-prime RMBS that I had to create a post dealing specifically with the issue! Default probabilities for lower grade retail credits are highly correlated – responding as they do to broader economic conditions – and the degree of correlation has important implications for pricing the various tranches of RMBS.
