US whey protein concentrate (WPC 80) fell from a summer high of about $13/lb to $9.20/lb by October 21, 2026, after almost three years of increases. Buyers cut orders from 12 units to six as manufacturers worked through stocks built during the rally, even as finished protein product demand stayed healthy.
Destocking by buyers after a stockpiling rally pushed dairy protein prices lower, though WPC 80 remains well above year-earlier levels. Lower prices may bring back import demand, particularly in Europe.
