Oil futures market opens up to black box trade

LONDON/NEW YORK (Reuters) - Black boxes control only a small share of oil futures, but their reach is growing, driven by an influx of cross-asset dealers.

Those who rely on computer power to generate profit from split-second price moves vary from Wall Street banks to small hedge funds.

Their presence in oil trading began with the shift on oil futures markets toward electronic trade and has gathered momentum as volatility has risen and as fall-out from the financial crisis has given a spur to cross-asset deals.

"We have seen a solid increase of black box based trading in oil in the past couple of years. But oil is way, way behind other markets because it is a specialist market, it has physical trade," said Paul Zubulake, senior analyst with U.S. consulting firm Aite Group.

There are no official figures on the extent of high-frequency trading, which include black box and algorithmic trade, on the oil futures market, but Zubulake estimated it had risen to around 10 percent.

On U.S. equities markets, where electronic trading dates back to the 1970s, industry analysts say automated trading accounts for an estimated 60-70 percent of volume on U.S. equities markets.

Oil exchanges gradually introduced electronic trade over several years and the Atlanta based-InterContinental Exchange (ICE) (ICE.N) went fully electronic in 2005. The New York Mercantile Exchange (NYMEX) still has open outcry trading, but bigger volumes are generated electronically.

A more recent spur has been this year's trading environment in which oil has been unusually tightly linked to bigger financial markets.
