CME CME Group Inc

CME Group (CME) has expanded its limits on how far oil can rise or fall for the rest of Thursday's electronic trading session, which ends at 5:15 p.m. EDT, said CME spokesman Chris Grams. Oil futures typically have a $10 limit on how far they can rise or fall in one session. That's been expanded to a $20 limit above or below the prior day's settlement, with the expansion triggered by the rapid freefall in oil futures during the last hour of trading, when limits are removed. Oil futures for June delivery ended Thursday's floor session off $9.44, or 8.6%, at $99.80 a barrel. They fell further in electronic trading, sinking below $99 a barrel.
