Black Sea Tensions Propel Global Wheat Prices to Peak
· Sabah Ekonomi

Geopolitical risks in the Black Sea and global climate anomalies are triggering sharp increases in agricultural commodities, with wheat prices on the Chicago Board of Trade reaching a one-year high, up 12.1% on a weekly basis.
Black Sea Tensions Propel Wheat Prices to Peak
Agricultural products exhibited a significant upward trend in the past week on global commodity markets. The escalation of conflicts between Russia and Ukraine, targeting Black Sea ports, grain-laden vessels, and logistics infrastructure, has severely jeopardized the global grain corridor. According to data from the Chicago Board of Trade, wheat prices rose by 12.1% on a weekly basis. The price of December futures contracts climbed to 790.3 cents per bushel, reaching its highest level since July 2023 and intensifying global supply concerns.
Climate Concerns Drive Corn and Soybeans
The rise in grains was not limited to wheat; upward price movements also strengthened for corn and soybeans, key inputs for the feed and food industries. Extreme heatwaves and erratic rainfall across the United States negatively impacted yield expectations in the fields. In Chicago Board of Trade trading, corn prices recorded a weekly increase of 5.5%, while soybeans gained 3.9% and rice rose by 2.5%. Strong export demand and flood disasters in China fueled concerns about product supply.
China Drought Stimulates Cotton Market
Adverse weather conditions in production centers directly affected the cotton market, an industrial agricultural product. Extreme drought and high temperatures in the Xinjiang Uyghur Autonomous Region, which accounts for over 90% of China's total cotton production, put pressure on crop yields. The price of cotton traded on the Intercontinental Exchange closed the week with a 3.5% increase per pound. Concerns about raw material supply for textile manufacturers kept buying interest in global cotton contracts alive.
Cocoa Season Delayed in West Africa
One of the most notable increases in agricultural commodities this week was recorded in the cocoa market. Insufficient sunlight in Ivory Coast and Ghana, the world's largest producers, reduced product quality and increased the risk of fungal diseases. It was reported that the main harvest season for 2026-2027 could be delayed by 8 to 10 weeks due to inadequate field maintenance and challenging meteorological conditions. As a result of these developments, the ton price of cocoa on the Intercontinental Exchange sharply increased by 10.0%.
Brazilian Harvest Pressures Coffee and Sugar
Developments in the main producer, Brazil, exerted downward pressure on prices in the coffee and sugar markets. The rapid progress of the harvest season in Brazil increased the physical supply available to the global market, causing coffee prices to fall by 3.1% weekly. However, the lowest level of certified arabica stocks since 1999 limited the decline. The price of sugar per pound fell by 0.3% with the depreciation of the Brazilian real, while the European Union's forecast of a 19% contraction in sugar production for the 2026-2027 season curbed losses.
Macroeconomic Pressures in Global Commodity Markets
While agricultural products gained value due to supply constraints, central bank interest rate policies became decisive for other commodity groups. The core personal consumption expenditures index, a measure of inflation in the US, exceeded expectations by rising 3.3% year-on-year. Fed Chairman Kevin Warsh, speaking at the Jackson Hole symposium, signaled a hawkish stance on monetary policy. Following these statements, the probability of a 25 basis point interest rate hike in September rose to 60%, and the dollar index climbed to 99.7.
Sharp Fluctuations in Energy and Precious Metals
Financial tightening and geopolitical developments led to sharp sell-offs in precious metals and energy markets. The price of gold per ounce, which climbed to $4,696.8 in the early days of the week, closed the week with a 3.2% decline; silver fell by 3.8%, platinum by 3.0%, while palladium rose by 5.3%. On the energy side, Brent crude oil prices lost 4.8% on expectations that the Strait of Hormuz could be opened for trade; natural gas, however, gained 4.2% due to demand driven by hot weather.
Base Metals: Stock Drawdowns and Tariffs
In industrial metals, planned US import tariffs and changes in London Metal Exchange stocks led to price divergences. Following a withdrawal order of 65,400 tons during the week, available copper stocks in London warehouses fell to 90,000 tons. In the over-the-counter market, zinc prices rose by 1.2%, aluminum and lead by 0.3%, while nickel fell by 1.9% and copper by 0.5% by the end of the week. The slowdown in global industrial demand limited gains in metals.
