How Long Can the US Be the Oil Supplier of Last Resort?

What do the Federal Reserve and the US oil industry have in common? In today’s war-torn market, both are the supplier of last resort. One provides dollars; the other barrels. But that’s where the similarities end. The central bank can print the currency at ease; the drillers cannot.

Facing an unprecedented shortage, the global oil market has called on the US, the world’s top producer, for help. And thanks to the shale revolution, America has been able to respond: Over the last four weeks, US net exports of crude and refined products have averaged a record high of 5.9 million barrels a day, up from 3.3 million a year ago. Only a decade ago, the US was a net importer in excess of 5 million.

US is the oil barrel

Can the US sustain that level of net exports forever? No — the American shale revolution is extraordinary, but not miraculous. The question, however, isn’t whether the nation can keep up with no end in sight; instead, it’s whether it can do it for long enough to keep oil prices from exploding before it reaches a deal with Iran. Looked through that lens, the US has the ammunition, thanks to its emergency stockpile, to sustain its outsized oil exports for several more weeks, perhaps even a couple of months.

The export boom is a key reason why oil prices have tumbled, particularly in the physical market (the portion of the market where real barrels, not swaps or futures, change hands). The collapse in Chinese oil imports has also helped, as have other well-known levers, like the use of bypass pipelines around the Strait of Hormuz.

The US, with its 2.6-million-barrel net export hike, is the biggest driver in an overall surge from the American continent. Others are contributing, too, and when combined, their extra exports do add quite a bit: Canada (400,000 barrels per day); Venezuela, Guyana, Colombia and Argentina (200,000 each); and Brazil (100,000). Together, the Americas are exporting, on a net basis, almost 4 million barrels a day more than they did around this time in 2025. That equates to one-quarter of the shortfall created by the closure of Hormuz.
