West Texas Intermediate crude oil, which had been selling for $105 a barrel at the end of March, fell to $80 a barrel last week, while Brent has come from $125 down to near $90. These price declines will translate into substantial savings for U.S. consumers in the weeks ahead.
Since Brent and WTI diverged, it has been Brent that matters for U.S. retail gasoline prices; this fact and the reasons for it were discussed here. A regression of the average U.S. retail gasoline price on the price of Brent over 2000-2012 captures the close relation (OLS standard errors in parentheses):
If gasoline prices do fall from their value in April near $3.92 to $3.12, that would be an 80 cents/gallon swing. With Americans buying about 140 billion gallons of gasoline each year, that translates into an extra $112 billion over the course of a year that consumers would have available to spend on other things besides gasoline.
So should we be celebrating? I’m afraid not. The primary reason that oil prices have come down is because of growing signs of weakness in the world economy. I am very concerned about where events in Europe are going to lead, and recent U.S. data indicate some weakening. Cheap gas helps, but not so much if you don’t have a job.
But I will offer this advice: wait another week or two if you can before filling up the tank.
