The three things that do the most to push up oil are weakness in the dollar, the dynamics of supply and demand, and natural disasters or manmade disturbances in the pumping of crude. Add to that, if OPEC is right, rampant and wide-spread speculation by traders.

The supply of crude out of the UK has been, for the time being, interrupted by a strike. According to Reuters, the strike over pensions began at a Grangemouth refinery in Scotland, operated by BP (NYSE: BP).

The strike raises the issue of whether Western governments should allow workers in oil fields and on pipelines to strike at all. The availability of oil and the huge jump in price to $120 makes a strong case for calling it a "strategic asset." The term has been applied to crude for many years, but it did not mean much when prices were lower and there was, at least from the standpoint of perception, ample supply.

The government of the U.S. needs to intervene and send the strikers back to work, or replace them, if necessary. Oil at $120 has as much chance of wreaking the economy as the credit crisis. The U.S., Europe, and Japan can only handle the pressure of so much commodity inflation. At some point, fighting inflation will become more important than cutting interest rates. Then, even Solomon will not be able to decide what to do.
