# Grain storage and seed policies keep advancing, hog forward supply improves; Yongying grain ETF (158047) and livestock ETF (159165) position in agricultural supply chain

> China's central reserves agency is running minimum-price purchases of mid-late rice alongside reserve rotation purchases of autumn grain, with rotation buying entering the market at slightly above market prices and faster than last year. New seed variety protection rules took effect November 1, and a brokerage cited a 6.8% year-on-year drop in domestic corn seed-production area for the 2026/27 season. Newborn piglet numbers fell for a second straight month in September, which analysts say could ease 2027 slaughter supply, though supply remains high.

## Why it matters

State purchases support domestic grain prices and farm incomes, while lower seed output and falling piglet numbers point to tighter future domestic corn and hog supply, mildly supportive for feed demand and prices.
