Kpler reports Panama Canal congestion hit a record 63 vessels in November 2020, driven by higher US exports and bad weather. The spillover raised ton-miles as ships diverted via Suez or the Cape, pushing tanker charter rates to a record $350k/day.
Canal congestion lengthens voyages and raises freight costs for US grain and energy cargoes bound for Asia, which lowers FOB competitiveness of US origin. Higher ocean freight narrows the arbitrage for US grains into Asian buyers.
