The small retreat is probably due to the dollar coming back a bit.

The continuation of cool weather in the United States is expected to bring big spikes in heating fuel demand.

Ordinarily comfortable inventories would mean lower prices -- probably closer to fifty-five dollars. But the Iran situation, and several smaller actual interruptions to crude supply, are keeping prices higher.

Something that could have squeezed supply a bit tighter would be a sustained cold snap and there just hasn't been the cold weather in the U.S. yet to test out just how well the market can supply.

The Iran-U.N. row and potential for economic sanctions reminds us that geopolitical situations remain a key factor in giving support to oil prices.
