An observation worth highlighting is, the maximum reserve was 726 million barrels December 2009. This was the first year of the Obama administration. There was a slow draw down since then, which includes the Trump administration. This draw down accelerated April 2021, so there is truth to the statement that the Biden administration has been drawing down the SPR. He accelerated a draw down that was already in progress. Over 12 years, the SPR was reduced about 90 million barrels. In 2 1/2 years since, it was reduced about 290 million barrels.
