Recent economic events around the world look like a news form a global battlefield consisting of flared up trade battles between some major economies. Clearly, the entire shipping industry is watching those developments and tries to de-risk their long term investment decisions and short term tactical moves.
It is a little bit like playing a game of tennis blindfolded and estimating the trajectory of the incoming ball from the sound made by the racket of the opponent. This uncertain world is reflected in the different strategies employed by the various carriers and various ports aiming to protect their trade volumes and contain their huge capital investments in infrastructure and equipment.
