A potential strike by the International Longshoremen's Association, affecting nearly 30 ports along the East and Gulf Coasts, could significantly disrupt supply chains, particularly during the critical holiday shopping season. If the strike occurs, it may lead to a daily economic loss of up to $5 billion, according to JPMorgan analysts, as these ports handle about 60% of U.S. shipping volume. Retailers like Walmart and LG are preparing for increased costs and supply shortages, with freight rates for shipping containers already surging by 29% as businesses rush to stock up. Major shipping companies, including Maersk and CMA CGM, are implementing surcharges to manage anticipated disruptions. The fallout could also constrict the supply of essential goods, resulting in higher prices for consumers. Smaller businesses may face the brunt of these impacts, as they lack the robust contingency plans of larger retailers.
