Is there high-closing in the FX market?

In the space of 20 minutes on the last Friday in June, the value of the U.S. dollar jumped 0.57 percent against its Canadian counterpart, the biggest move in a month. Within an hour, two-thirds of that gain had melted away.

The same pattern — a sudden surge minutes before 4 p.m. in London on the last trading day of the month, followed by a quick reversal — occurred 31 percent of the time across 14 currency pairs over two years, according to data compiled by Bloomberg. For the most frequently traded pairs, such as euro-dollar, it happened about half the time, the data show.

The recurring spikes take place at the same time financial benchmarks known as the WM/Reuters (TRI) rates are set based on those trades. Now fund managers and scholars say the patterns look like an attempt by currency dealers to manipulate the rates, distorting the value of trillions of dollars of investments in funds that track global indexes.

Because they receive clients’ orders in advance of the close, and some traders discuss orders with counterparts at other firms, banks have an insight into the future direction of rates, five dealers interviewed in June said. That allows them to maximize profits on their clients’ orders and sometimes make their own additional bets, according to the dealers, who asked not to be identified because the practice is controversial.

A large proportion of trading at that time is generated by index funds, which buy and sell stocks or bonds to match an underlying basket of securities, the traders said.

Banks that have agreed to make transactions for funds at the 4 p.m. WM/Reuters close need to push through the bulk of their trades during the window where possible to minimize losses from market movements, the traders said. That leads to a surge in trading volume, which can intensify any moves.

Fund managers rarely complain about getting a bad deal because they’re assessed on their ability to track an index rather than minimize trading costs, according to consultants hired by companies and investors to help execute trades efficiently.

“Where possible, I would always advise clients not to trade at the fix — but minimizing tracking error is so important to them,” said Russell’s [head of foreign exchange Michael] DuCharme. “That doesn’t seem to be the right attitude to take when you have a fiduciary duty to seek the best execution for pension holders.”

Hurrah for Mr. Ducharme who, unlike most market participants, appears to have retained the brains he was born with. It seems to me that there’s an opening for a market player to run a trade matching service on a subscription basis … orders are put in by subscribers throughout the day, all net imbalances are disclosed (to subscribers only!), all matching orders are filled at the benchmark rate based on time-stamp, all non-matching orders are cancelled. There would have to be a few rules to enforce all this, but it could work…

The portfolio managers have my sympathies – investing or generating significant amounts of cash to meet client orders can have a huge effect, given that indices are calculated at the close. Perhaps what’s needed is indices and portfolio valuations based on VWAP rather than closes … but that’s only going to work in very liquid markets.

It was a modestly good day for the Canadian preferred share market, with PerpetualDiscounts winning 13bp, FixedResets gaining 7bp and DeemedRetractibles up 10bp. There’s a surprisingly lengthy Performance Highlights table, totally disproportionate to the market move. Volume was very high.
