U.S. wheat futures jumped Monday on renewed concerns over grain export availability from the Black Sea following the Biden administration's authorization for Ukraine to use U.S.-supplied missiles in its war with Russia.

Ukraine, which has long pleaded with the U.S. to allow it to use the Army Tactical Missile System, or ATACMS, is expected to first deploy the missiles to Russia's Kursk region, where Russia's forces are fighting to take back territory seized by Ukraine in a surprise summer offensive.

"The geopolitical uncertainty of the Black Sea has end users extending their forward coverage while the managed money lifts out of net wheat short holdings," AgResource said; other analysts said last week's steep selling set up gains for CBOT futures.

CBOT wheat (W_1:COM) for December delivery closed +1.9% to $5.47 1/4 per bushel, while December corn (C_1:COM) finished +1.2% to $4.29 1/4 per bushel, and soybeans (S_1:COM) for January delivery settled +1.2% to $10.10 per bushel.

Soybeans ended higher after spending much of the session under pressure due to rainfall that is assisting the development of the Brazilian crop; some analysts saw short-covering as the primary reason futures recovered late.
