Suez Canal Authority via AP After the Ever Given blocked the Suez Canal, industry insiders are taking note of other risks. Bigger ships, more automation, and smaller crews are concerns, said Capt. Rahul Khanna, of Allianz. Climate change has made a shipping route through inhospitable Arctic waters more popular. Shipping vessels have grown larger by multiples in just a few years, adding to worries among some industry insiders that a single mistake made by a massive ship could cause a global supply chain disruption, as the world saw with the Ever Given. That ship, which was stuck in the Suez Canal for about a week in March, slowed or stalled shipping traffic around the world. It was estimated to cost the global economy about $400 million per hour, and its effects have still been rippling through the economy in recent weeks.
