Energy analysts at The Schork Group Inc. said open interest, which is the number of open futures contracts, is at record levels as is the participation of Wall Street hedge funds and investors such as commodity pool operators. They said in a report that Wall Street now owns six times as many barrels of oil in the WTI futures market as there are sitting at the Nymex oil delivery terminal in Cushing, Oklahoma.
Oil prices were also supported by a weaker dollar, which makes crude and other commodities priced in the U.S. currency cheaper for traders using other currencies. On Monday, the euro was up at $1.3169 from $1.3138 on Friday.
Benchmark oil's jump has been so sharp that is has closed most of its discount to Brent crude, which is traded on the ICE Futures exchange in London. September Brent was up 23 cents to $108.30 a barrel.
In other energy futures trading on the Nymex:
Wholesale gasoline lost 0.07 cents to $3.0511 a gallon.
Heating oil rose 0.79 cent to $3.0973 a gallon.
Natural gas retreated 7.5 cents to $3.714 per 1,000 cubic feet.
