Grain markets rallied on the announced US-China Phase One trade deal, which had not yet been signed. March corn futures tested resistance near $3.82 as funds covered shorts, and soybeans rose sharply on Friday before giving back some gains.
Tariff relief and a $40-50 billion Chinese ag purchase commitment support demand for US grains and soybeans. Heavy fund net short positions add short-covering fuel to prices.
