SPRWhether or not to release oil from the SPR is a political decision based on risk/reward analysis. Assume the U.S. consumes about 20 million bpd and produces around 12 million bpd. Then the shortfall/day would be around 8 million bpd. With 300 to 400 million barrels in the SPR, there would be 35-50 days of oil cushion if all imports were stopped. But Canada supplies about 3.5 million bpd out of that 8 million bpd shortfall. The idea that all U.S. production and all imports would stop at the same time sounds farfetched. The risk for the U.S. is small. If the U.S. helps put a floor under the market down the road so be it.
