Much of the decrease of the price of gas at the pump is because American's strategic oil reserves have been used up and drained.
Ehhhh, kinda. But not "much". More like, "a bit".
About 285 million barrels of oil have been released from the SPR since the start of the Biden Administration. That translates to about 132.1 million barrels of gasoline (as on average 46% of a barrel of oil is cracked for gasoline).
That's helped smooth out some fluctuations and clip some peaks (which are both among the reasons the SPR was originally created), but not really reduced prices overall.
US gasoline consumption is just short of 9 million barrels per day. So, that 132.1 million barrels is about 14 1/2 days worth of gas use, maybe 15 1/2 if you include slower consumption in 2021/2022.
So, the entire SPR release accounts for about
1.5% of total US gasoline use since the Biden Administration started.
As for being "used up and drained", there are still 351 million barrels remaining in the SPR (it's up about 5 million barrels since July). There are also another 430 million barrels sitting in commercial inventories (up from a low of 414 million barrels in late August).
This was stupidly done in order to decrease the cost of gas at the pump. However, it was very dumb to do so because those strategic oil reserves are best used for national and global emergencies, instead of using them for political purposes.
I hate to both sides this, but the Trump administration did the same thing, and largely for the same reasons. They put about 65 million barrrels from the SPR out into the market between early 2017 and the end of 2019. Then, when oil prices cratered during the pandemic, they purchased about 20 million barrels.
The only other time it was done like that was in 1996-97 by the Clinton administration.
