US ethanol stocks fall to 23.9 million barrels, tightest since January, as exports climb

US ethanol inventories dropped to 23.928 million barrels in the latest week, the tightest level since the first week of January, according to the EIA. That is a decline of 762,000 barrels on the week and 31,000 on the year. Stocks fell in nearly every reporting region, which points to solid domestic demand rather than a supply problem.

The one exception was the Gulf, where stocks grew. That usually means product is being staged for export, so the tightening at home and the build on the coast tell the same story: more ethanol is heading out the door.

Exports

The Renewable Fuels Association put ethanol exports at an average of 200,000 barrels per day, up 74,000 from the prior week. A separate read from Farms.com had exports rising 11% on strong global demand. Brownfield reported that ethanol and DDGS shipments both rose in May, so this is a trend with a few weeks behind it, not a one-week blip.

For a US jobber, none of this hits the rack price tomorrow. But a market pulling barrels offshore while domestic stocks draw down is a firmer market, and if the pace holds it could keep ethanol values supported into the back half of summer even with corn where it is.

Corn demand

Year-round E15 could add to corn demand, per Farms.com. Nothing new landed this week to change the regulatory picture, so treat this as the standing upside case for the blend rather than a fresh catalyst. If more states clear year-round E15, that is incremental gallons on top of the export pull, and it would tighten the domestic balance further.

The Greenfield deal

Greenfield Global signed a long-term agreement with Show Me Ethanol to expand its high-purity alcohol supply network. That is industrial and beverage-grade alcohol, not fuel ethanol, so it does not move RIN or blend economics. It matters here only as a reminder that some plants can shift product toward higher-margin alcohol markets when fuel demand is soft.

What to watch

Watch next week's EIA number for whether the Gulf build keeps growing. Watch whether the RFA's weekly export pace stays near 200,000 bpd or fades. And watch corn, because the export story only helps producer margins if feedstock costs stay put. Nothing this week touched the RFS or RIN prices directly, so the near-term push on ethanol values is coming from demand, not policy.
