On a quarterly basis, PCE, "Gasoline and other energy goods" peaked at $467 billion (SAAR) in Q3 2008, and fell sharply to $265 billion (SAAR) in Q1.
The sharp decline in oil prices provided a cushion for the U.S. economy in early 2009.
Now, with U.S. spot prices over $100 per barrel, gasoline and other energy goods PCE will probably come in around $425 billion (SAAR) in Q1 2011 (up from $379 billion (SAAR) in Q4 2010. This was already over $400 billion SAAR in January.
This is a drag on consumers of about $5 to $6 billion per month, at the current oil price, compared to the average for 2010.
