Shipping through the Suez Canal has been disrupted by a sequence of vessel groundings and collisions started by a container-vessel. That highlights the physical disruption risks faced by the logistics industry. It follows a 4% increase in the number of shipments through the canal in the past 12 months on a year earlier to reach the highest since August 2010 in May. The scale of vessels is also rising with the average size of containerships having risen by 7% annually in the past three years.
