The US dairy market entered 2026 expected to be well-supplied across most categories. That picture has changed materially. Butter is tight, powder is tight, and the whey protein complex is the tightest it has been in years. Here’s the overview.

Milk production remains solid heading into 2026. Dairy herds are large, supported by favourable farm economics: beef markets are delivering strong returns for culled cows, and feed costs are manageable. Component levels, fat and protein, are tracking above historical averages, meaning the effective yield of dairy products per unit of milk is elevated.

Butter is the market that has most surprised to the upside. January production was up 6% year-on-year, but strong domestic demand and surging exports have absorbed that and more. Stocks are down 17% versus a year ago, approximately 15% below the five-year average, and at their lowest level in five years. The CME “new crop” rollover on 1 March restricted eligible supply overnight, contributing to a sharp price increase. The market now looks firm through at least H1 2026.

NFDM and SMP production has been running at multi-year lows as processors redirect capacity toward higher-value products: cheese, fresh milk, and protein concentrates. Stocks of around 215 million pounds have barely moved since December. The US has effectively stepped back as a reliable global exporter, pushing international buyers toward European and New Zealand origins.

Cheese production has expanded, but the bearish consequences have been less severe than expected. Stocks remain low primarily because exports have surged, absorbing volumes that might otherwise have pressured domestic markets. The stronger Euro has reinforced US price competitiveness on export markets.

WPC80 is the tightest product in the complex. Q2 volumes are close to sold out, safety stocks have fallen to below one month of production, and negotiations are about securing volume rather than price. WPI production growth was up 12.4% year-on-year in January, though this is running slower than WPC80 growth, confirming WPC80 as the more acutely constrained product. Sweet whey powder is moving in the opposite direction: new processing capacity and high cheese production are adding supply, with US SWP prices easing modestly.
