UPDATE: Petroleum imports are strong in dollar terms, but they appear to be declining in BBLs, see exhibit 17. Imports are noisy month to month, but BBLs imported has declined year over year for the last several months. Also note the price per barrel. This will increase sharply over the next few months (but not to the spot level). Hat tip dryfly.

Normally oil prices would now be falling as the U.S. economy weakens - instead we are seeing margins shrinks for U.S. refiners and record high oil prices. This would imply that global demand for oil is strong, while domestic consumption is weak. This evidence supports the "decoupling" argument: that the U.S. economy could slow, but economic growth in the rest of the World would stay strong. I'm not convinced by the decoupling argument, and my view is that there is simply a lag between a slowing U.S. economy and a slowdown for the rest of the world.
