Yep. There's also been huge demand surges as Covid restrictions loosened around the world, especially post-stimulus in the US. But shipping containers were in all the wrong places. Recently in the port of LA, they were sending the ships back across the Pacific without refilling them with empty containers because it would cost more to keep the ship in port those extra hours to load the empties than to send it back and buy newly made containers. The port was running 24-7 at greater than what would be normal peak capacity and they still couldn't unload ships fast enough to prevent historic levels of buildup. Dozens of ships were just hanging out, anchored offshore while waiting to be unloaded.
