Kerch Strait Tensions Threaten Global Food Supplies

The Kerch Strait has become a hotspot of tension in the Black Sea, threatening to disrupt global food supplies. The region's importance cannot be overstated, as it accounts for over a quarter of the world's wheat exports, with Russia and Ukraine together providing roughly 15% of corn and barley, and over 60% of sunflower oil. This is not the first time supply shocks have occurred in the area; past disruptions have shown that they can spread from one commodity to another. For instance, when sunflower oil becomes scarce, it drives up soyabean and palm oil prices.

The current situation is precarious due to the interactions among different 'systems' - the ongoing Russia-Ukraine war, the US-Iran conflict, and weather conditions such as El Niño and European heatwaves. The combination of these factors creates a perfect storm that policymakers must stay vigilant about.
