# What’s Behind the Latest Surge in Grain and Oilseed Prices?

> Benchmark grain and oilseed futures have risen strongly since August, with corn and oats each gaining more than 12% by mid-September. The move is attributed to the Iran conflict lifting energy costs, adverse weather in key growing regions and tighter-than-expected supply forecasts. Diesel and fertilizer costs for US producers have also climbed sharply.
