I've been following this for a while, and it's encouraging news if the commodities regulators follow through. These guys have been driving up the cost of oil with the same sort of shady tactics used in the financial markets. Good for the Obama administration if they take this aggressive approach:

WASHINGTON — Reacting to the violent swings in oil prices in recent months, federal regulators announced on Tuesday that they were considering new restrictions on “speculative” traders in markets for oil, natural gas and other energy products.

The move is a big departure from the hands-off approach to market regulation of the last two decades. It also highlights a broader shift toward tougher government oversight under President Obama.

Since Mr. Obama took office, the Justice Department has stepped up antitrust enforcement activities, abandoning many legal doctrines adopted by the Bush administration.

The Obama administration is also proposing an overhaul of financial regulation that would include tougher capital requirements for big banks, tighter regulation of hedge funds and a new consumer protection agency with broad power to regulate credit cards, mortgages and other consumer lending.

In the case of oil and gas trading, regulators made it clear that they were willing to move, without waiting for Congress to act on Mr. Obama’s overhaul, invoking their existing powers.
