Germany and the United States are backing G20 negotiations on restoring safe commercial shipping in the Black Sea. Proposals under review would split traffic into separate Ukrainian and Russian corridors and have Turkey, India or Egypt register vessels as neutral guarantors.
If a neutral-flag corridor arrangement restores Black Sea grain flows, it would ease freight costs and add supply to export markets, which is bearish for wheat and corn prices. The proposals are still under discussion, so the effect is uncertain.
After 80 past bearish geopolitics events, Wheat (SRW) moved a median -0.4% over 5 sessions (44% higher; middle half -1.4% to +1.9%), and -0.5% over 20.
After 87 past bearish geopolitics events, Corn moved a median +0.1% over 5 sessions (51% higher; middle half -1.5% to +2.1%), and +0.3% over 20.
