For the first time ever, hedge funds hold more than a billion barrels of bets that crude oil prices will rally. Money managers last week extended their faith in OPEC-led supply cuts, increasing outright long positions in the global benchmark Brent and its U.S. counterpart West Texas Intermediate to a fresh record. Speculators are on hold, though, with futures in New York stuck in the tightest range in 13 years and Brent implied volatility the lowest in more than two years, data compiled by Bloomberg show.
