Black Sea and Sea of Azov Shipping Disruptions: The Core Cause

The primary driver of the export collapse is a surge in military attacks targeting commercial shipping and port infrastructure in the Black Sea and Sea of Azov . These attacks have turned the region into a critical trade chokepoint. Key incidents include:

• Taman Terminal Strike: On July 29–30, Ukrainian drones struck the Demetra-Holding Taman grain terminal complex on the Russian side of the Kerch Strait. This deep-water facility has a 5.5 million tonne annual loading capacity . The same attack destroyed EFKO's adjacent vegetable-oil export dock .
• Sea of Azov Shutdown: Russia has been forced to suspend traffic through the Sea of Azov after Ukrainian attacks effectively shut down the waterway .
• Russian Escalation: Russia's transportation ministry stated on August 3 that it was stepping up protection of ships in the Azov-Black Sea basin and developing alternative cargo routes in response to the "tense situation" .

On the Ukrainian side, the situation is equally bleak. No vessels entered ports in the Odesa region for two weeks . Ukraine's alternative export routes are not expected to reach full capacity before the end of August and will cover only about half the usual volume .

The Domestic Market Paradox: Oversupply and Falling Prices

A strange paradox has emerged. Despite the export blockade, Russia has collected a large harvest—over 72 million tonnes of grain, including 60 million tonnes of wheat . The combination of a large harvest and blocked export routes has created a domestic glut. This, in turn, is driving down prices for Russian farmers, making them even more reluctant to sell at a loss and further dampening export activity even where routes are open .

The Government's Response: Higher Export Taxes and a Subsidy Package

In response to domestic price pressure, the Russian Ministry of Agriculture has taken a seemingly counterintuitive step: raising export taxes. After keeping the wheat export duty at zero for three consecutive weeks (July 9 – August 4), the ministry reinstated it . The duty was set at 5.7 rubles per tonne for August 5–11 . Then, effective August 12, it jumped over 50-fold to 326.6 rubles per tonne . The stated rationale is to manage domestic price pressure, but it further depresses the already struggling export competitiveness.

Simultaneously, the government is preparing a 10 billion ruble ($122 million) package to subsidize rail shipments of agricultural products, attempting to redirect exports away from the beleaguered Black Sea ports .

Global Wheat Price Implications and Food Security Warnings

The crisis is having immediate global repercussions. Global wheat prices have already risen as the scale of the Russian export disruption becomes clear . The most severe warning came from Russia's own Union of Grain Exporters on July 31. They stated that Ukrainian drone attacks could shut down Black Sea grain exports entirely in the near future, pushing up global prices and threatening famine in some of the world's poorest nations, particularly those in Africa and the Middle East that rely heavily on Black Sea wheat .

Industry Forecasts: Reduced Harvests and Export Potential

The crisis is compounded by downgraded harvest forecasts. On July 24, the Institute for Agricultural Market Studies (IKAR) cut its 2026 Russian grain harvest forecast to 139 million tonnes (from 142.5 million tonnes), of which 90 million tonnes is wheat . The reduction was attributed to adverse weather in Siberia and the Urals . IKAR also lowered its 2026/27 wheat export potential to 44.5 million tonnes, down from earlier expectations . The market is now closely watching the upcoming USDA WASDE report for a formal acknowledgment of these significant supply losses .
