Hedge funds switched from net-short to net-long on London and New York oil benchmarks in the week to 9 June. That joint reversal had not happened since mid-May. One day later, the Brent price fell more than 4%, settling at $87.33 on 12 June.
Traders who placed those bets near the recent high of $97.82 are now sitting on losses. A fast exit would push prices lower still.
