Hedge funds and other money managers raised their bets on rising Brent crude oil prices for a fifth week in a row to a new record, exchange data showed on Monday. Speculators increased net long positions in Brent futures and options by 8,351 contracts to 271,929 in the week to April 21, InterContinental Exchange (ICE) data showed, the highest level since records began in 2011. “We have more or less seen longs rise since October so it’s been going on for some time,” said Ole Hansen, head of commodity strategy at Saxo Bank. Brent crude prices fell by more than half between June and January.
