Show Notes
A sudden 145% U.S. tariff on select Chinese imports is sending shockwaves through West Coast ports—and reshaping trade flows in real time. In this episode, we examine the steep drops in cargo volumes at Los Angeles, Oakland, and Seattle ports, unpacking how new tariffs are choking imports and prompting blank sailings, layoffs, and fears of recession. Drawing from the article West Coast port slowdown: Shipments plunge as U.S. tariffs take their toll, we trace how this policy shift is not only disrupting logistics, but threatening consumer access, job stability, and long-term economic momentum.
From container backlogs to retaliatory export risks, this episode is your on-the-ground look at how global trade tensions are playing out at America’s most critical supply chain hubs.
