Black Sea Grain Chokehold Puts Global Markets on High Alert

Escalating mutual attacks between Russia, the world's largest wheat exporter, and Ukraine, known as "Europe's breadbasket," are paralyzing maritime transport in the region during the new harvest season, creating a serious risk of supply shock in global food security and grain markets.

Critical Bottleneck in Supply Chain

Although Ukraine's grain and oilseed production is expected to reach 81 million tons this year, the export of these products, which constitute 60% of the country's total exports, is being blocked. According to data from the Ukrainian Ministry of Infrastructure, 35 attacks on ships in ports, 22 on ships at sea, and 67 on port facilities were carried out in July alone. These attacks have largely halted commercial traffic in the ports of Odesa, Chornomorsk, and Pivdennyi, where over 90% of exports are conducted.

■Maersk has suspended its connection service via Chornomorsk due to security risks, redirecting cargo to the Port of Constanța in Romania.

■Ukrainian Minister of Agriculture Taras Vysotskyi stated that ship owners have stopped sending vessels to the country's ports as of July 22.

■It is predicted that alternative land and river routes will not reach full capacity until the end of August, and at best, they will only be able to meet half the capacity of Black Sea ports.

Mounting Operational Risks at Ports

Damage to export terminals at Russia's Taman Port and the restriction of vessel movements in the Sea of Azov since July 10 also threaten the export capacity of the opposing side. While loading speeds have decreased in Novorossiysk and Tuapse ports due to security measures, the Russian Union of Grain Exporters has warned that export corridors could close completely if current conditions persist.

■Ship owners are prioritizing the minimization of operational risks due to the attacks.

■Rising insurance premiums have the potential to push global food prices upward by reflecting on freight costs.

■The UN World Food Program warned that global food insecurity could deepen if attacks on commercial routes continue.

Risks Reverberating Through Global Markets

The alternative corridor established after the expiration of the Black Sea Grain Initiative, through which 33 million tons of grain were shipped last year, remains dysfunctional due to intensified attacks. The increase in price and supply pressure, particularly in African and Middle Eastern countries dependent on imports from the region, is triggering volatility in commodity markets.

Our historical regression models forecast the lagged effect of such supply-side shocks on Core CPI at 2-3 quarters. This disruption in the Black Sea corridor creates a "surprise index" above market expectations, pulling the variance of food inflation upward. The explosion in import costs, particularly for emerging markets, presents a dataset that will further complicate monetary policy decisions.
