Russia's record 135 million tonne grain harvest has strained its three main deep-water ports. Traders are using ship-to-ship transfers in the Sea of Azov and Kerch Strait, and Novorossiysk has moved to a 24-hour shipping schedule.
About 20 percent of Russian grain terminals used such transfers last year.
Port bottlenecks raise logistics costs and can slow Russian wheat loadings, which tightens near-term export supply and supports Black Sea wheat FOB prices.
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.
