U.S. SPR falls to a 43-year low

U.S. Strategic Petroleum Reserve stocks have plunged 20.7% YoY to a 43-year low.
That is a major energy security signal.
The SPR is meant to act as a buffer during supply shocks, geopolitical disruptions, and oil market stress.
With inventories this low, the U.S. has less emergency flexibility if crude markets tighten again.
For $WTI, low reserve levels can add another layer of risk premium if supply concerns return.
