Black Sea Tensions Send Wheat to Limit-Up, Corn Higher
Wheat prices jumped sharply because fighting around the Black Sea could interrupt grain shipments.
A report said Russia may consider more missile strikes on Kyiv and other parts of Ukraine.
Recent attacks have already slowed grain loading at Russian and Ukrainian ports.
This made traders worry that less wheat and corn might reach world markets.
Corn prices also rose because a field tour predicted a smaller U.S. harvest than the government expects.
Every corn contract reached its highest level for the contract.
Soybean prices increased too, partly because China kept buying soybeans from the United States.
These concerns pushed several important crop markets higher.
Chicago wheat futures rose 45 cents to $7.48-1/4 per bushel, reaching the daily trading limit.
The rally followed a report that Russia was considering expanded ballistic missile strikes on Kyiv and other Ukrainian targets.
Russian and Ukrainian Black Sea grain loadings have nearly halted amid recent tit-for-tat attacks.
Corn futures reached life-of-contract highs, supported by wheat strength and expectations of weaker U.S. yields.
Soybeans rose 28-1/4 cents as China continued buying U.S. soybeans and crude oil prices recovered.
