However, one thing that is easily missed is how shipping lines have been operating at a loss/narrow margins for years, e.g., Hanjin bankruptcy: https://www.wsj.com/articles/south-koreas-hanjin-shipping-fi.... Many of the major shippers are not interested in building out capacity right now (e.g., Maersk CEO has consistently messaged this: https://splash247.com/if-msc-ends-up-having-more-capacity-th... ). It makes sense: why would they when they know that inevitably shipping rates will fall and they will have excess capacity on their hands.
Instead, they are essentially adopting a wait and see approach. In the meantime, shipping customers pay more, the shipping companies strengthen their balance sheets and reward shareholders with fat dividends, and finally demand will settle down naturally.
What some fail to realize is that this will take a decent amount of time. In particular, no one expects easing of the shipping situation until 2022: https://www.joc.com/maritime-news/container-lines/hapag-lloy...
