Ron Paul has been saying forever that the price of oil mirrors fed monetary policy.
When they pump tons of cash into the economy, everyone has more money, so everyone wants more money to part with things they value. Basic supply and demand... only nobody on the radio ever admits that money itself is subject to the law of supply and demand.
When they take money out of the system, everyone has less, and so will settle for less of it to part with things they value.
I don't know whether they're taking money out yet, but they've at least stopped pumping money in. Here we are two months later and everyone has kind of figured out that the dollar isn't going to be worth a whole lot less a month from now, so prices have stabilized.
Silver is also down almost to $15 from a January price of $20.
Other things to consider are
1) The overall tendency of the market is always to LOWER prices.
2) Sure, there might be downward pressure from suppliers - because when a good or service is wicked expensive the natural tendency for the providers thereof is to get as much of it out to market as they can. I'd bet that if you look at production figures you'd see that they tend to ramp up production when oil is expensive and throttle it back when it's not.
