John Paul Hampstead of Freightwaves points to escalating conflict between the US and China as a source of supply chain disruption:

“I expect the U.S.-China rivalry to express itself through gamesmanship in a number of spheres, including technology, international law, diplomacy, trade practices and military posture. The uncertainty and chaos of this changing trans-Pacific paradigm β€” from decades of decreasing friction and lower costs to a new trend of increasing friction and higher costs β€” will drive unpredictable and disruptive shipper behavior similar to that seen in 2018, 2020 and 2021. Stockouts will be followed by inventory gluts and vice versa, as importers pay too much to move their goods that are stored too long and arrive too late, compressing gross margins…

For 20 years, the trans-Pacific was relatively easy, boring and cheap. Now it’s becoming exciting, difficult and expensive β€” and will probably stay that way for some time to come.”
