Could Iran war trigger the next global food shock?

First came the energy shock. Now, the Iran war is hitting something even more basic: Food.

With the Strait of Hormuz blocked, vessels are being rerouted and supply chains are under strain.

The disruption is pushing up the costs of almost everything from factories to supermarket shelves thousands of miles away.

The longer the Iran conflict continues, the greater the pressure on businesses and consumers worldwide.

The United Nations warns that rising food, oil and shipping costs could push an additional 45 million people into acute hunger – taking the global total above its record of 319 million.
