Not as egregious as a general release to the market, but a bad precedent set treating the Strategic Reserve as a bank.
They didn't set the precedent.
Following a storm, this type of exchange, X barrels now, X + premium barrels returned later has been done several times before.
In my opinion, this exchange is what the SPR was set up to do. Provide oil in a timely manner following a supply interruption. There was a lot of the Gulf Shut down due to the Isaac. No major damage and the production platforms are coming back online, but they were shut down.
This is kinda like borrowing from your kids piggy bank.
