A Commonwealth Bank of Australia economist forecast that global grain prices, including wheat, could rise 18–24% in 2027 if Black Sea ports remain closed. The report said that reopening the ports early in the year would instead keep prices near current levels.
Continued port closures would restrict exports from a major grain-exporting region and tighten global wheat availability, creating upward price risk. Reopening the ports would ease that supply pressure.
After 283 past bullish logistics events, Wheat (SRW) moved a median -0.2% over 5 sessions (46% higher; middle half -1.4% to +1.3%), and -0.1% over 20.
