Are margin requirements going to be raised for trading Crude Futures?

Quote from 5yrtrader:

They did raise the margin requirements, they announced it on the 6th. Crude oil has gone straight up since then. I have seen raising margins effect markets before, usually goes done on the day it happens as people adjust their positions, but then continues the trend. Oil didn't even tick down on it, this is one strong market.

I'm sure the commercials are quaking in their boots, now the Exxon traders might only be able to buy 9500 CL's at the market instead of 10k next time there's a "pipeline incident"

My guess is ultra short-term this might just force out a few small specs who were net short and the most likely candidates for overleveraging - the guys paying a handle above the 230pm close today weren't building long positions.
