The United States is burning through its crude oil reserves faster than expected. Commercial crude inventories—the total amount of oil stored across the country—dropped 7.2 million barrels in one week, then fell 8 million barrels the week before, according to the EIA Weekly Petroleum Status Report. That is roughly 15 million barrels in fourteen days.

To put it plainly: companies are using more oil than they are bringing in. Crude imports fell 5.8% compared to last year, with the country averaging 5.9 million barrels per day over the past month, per EIA data. Either refineries are deliberately buying less crude, or global trade patterns have shifted, or both. Either way, U.S. oil reserves are shrinking, and unless domestic oil production ramps up, that trend will continue.

China's Oil Buying Spree

There is another piece to this puzzle that most people miss: China. Last year, China added about 1.1 million barrels per day to its strategic oil reserves—the national stockpile that governments keep for emergencies, according to the EIA. That brought China's total reserves to roughly 1.4 billion barrels by the end of 2025.

Why does this matter? Because China is a major reason oil prices have not fallen further. If China stops buying so much oil—whether because its storage tanks are full or because it decides it has enough reserves—that demand disappears. Global oil markets lose a buyer that has been keeping prices propped up. That could push oil prices down, even if the U.S. is running low on reserves.

Why This Affects Gas Prices and Your Wallet

When oil inventories drop, the gap between what people can sell oil for today versus what it will cost to buy oil later narrows. That can discourage storage and encourage faster delivery, which tightens the market even more.

If this pattern continues through the summer months—when refineries run hard and demand for oil climbs—U.S. reserves could fall to 420 million barrels or lower. That would be a real shortage, not just a routine seasonal dip.

A word of caution: weekly oil inventory numbers bounce around. One big drop might just reflect the timing of a ship arriving or a refinery shutting down for maintenance. Two big drops in a row is worth paying attention to, but it is not yet proof that something fundamental has changed. The next EIA report, due this week, will show whether this pattern is sticking around.
