I'm not sure I believe this.
Let's start with that which is market-based.

That's MF Global, a major futures clearing house. There was an
earnings warning out on them yesterday but that price action suggests something
far more serious - like insolvency. Down 40% in one day? That's a bit
more than a "warning", don't you think?
If they - and I stress that I know exactly nothing about the
firm in terms of its financials - were to blow up, it could produce absolute
chaos in the futures markets. Many futures contracts are not covered by SIPC
protection, among other problems. Clearing firm bankruptcies are no
laughing matter!
Now this may be a street overreaction, but if you remember there were rumors
before that turned out to be a "rogue trader" type of event. Now the stock is
back to where it was then, all in one day. Not good
and until clarity is available you have to be cautious on this one. How? Good
question - who clears your futures trades and how sound are they?
Point being, this is potential "black swan" #1.
President Bush has called for opening offshore drilling (its about damn time)
but the response of the Democrats was frightening:
"House Democrats responded to President's Bush's call for Congress to lift
the moratorium on offshore drilling.
