Container shipping rates for key global trade routes have soared this week, with U.S. and UK air strikes on Yemen stirring fears of a prolonged disruption to global trade in Red Sea, one of the world’s busiest routes.

Many shipping companies have pulled their vessels from the Suez Canal route as Houthi rebels in Yemen continue to fire at cargo ships. Some exporters are now using the overland rail route between China and Europe, with enquiries doubling since the Red Sea attacks began.
