Chicago wheat futures experienced a decline following their sharpest fall in almost three years. This came despite earlier hopes for a peace agreement between Russia and Ukraine, which have since faded due to continued conflict in the Black Sea region. The futures initially rose by as much as 1% on Friday but then reversed to a loss after Russian forces attacked two vessels in the Black Sea and Ukraine targeted a service ship involved in repairs at a key oil terminal in the area.

This recent drop marks the first weekly decline in five weeks for Chicago wheat futures, following a 2.6% decrease in the previous session. Russian President Vladimir Putin had previously indicated the possibility of constructive peace negotiations, which had momentarily spurred some optimism in the market.

However, the ongoing attacks underscore the persistent risks to Black Sea grain exports. Traders are closely monitoring the situation, as the physical security of shipping routes remains a critical factor influencing price direction. The market's reaction reflects the fluctuating sentiment tied to geopolitical developments and their impact on global supply chains.
