It has been a week since the Dali, a container ship, struck the Francis Scott Key Bridge in Baltimore. It’s still stuck there, and the images remain amazing, in part because the vessel is so huge compared with what’s left of the bridge. How could planners not have realized that operating superships in the harbor’s confined waters posed a risk?
And with the ship and pieces of the bridge blocking the harbor entry, the Port of Baltimore remains closed. How big a deal is that for the economy?
Well, it would have been quite a big deal if it had happened in late 2021 or early 2022, when global supply chains were under a lot of pressure. Remember when all those ships were steaming back and forth in front of Los Angeles, waiting for a berth?
It’s less important now: Pre-Dali Baltimore was only the 17th busiest U.S. port, and there’s apparently enough spare capacity that most of the cargoes that would normally have passed through Baltimore can be diverted to other East Coast ports. The Dali is no Ever Given, the ship that blocked the Suez Canal when it ran aground in 2021.
Still, global supply chains don’t have as much slack as they did, say, last summer, after the pandemic disruptions were mostly a thing of the past, because Baltimore isn’t the only problem. The Panama Canal is operating at reduced capacity because a historic drought, probably in part a consequence of climate change, has limited the supply of water to fill the canal’s locks.
Elsewhere, the Houthis have been firing missiles at ships entering or leaving the Red Sea, that is, heading to or from the Suez Canal. Presumably as a result of these and other problems, the New York Fed’s widely cited index of global supply chain pressure, while still not flashing the red lights it was showing in the winter of 2021-22, has worsened significantly since last August:
