Commercial shipping traffic through the Panama Canal has surged, with tankers and cargo vessels facing median delays of about three and a half days to enter the 82‑kilometer waterway. The backlog, the worst since the 2023–2024 drought‑driven disruptions, has intensified as energy flows are rerouted away from the Strait of Hormuz amid the Iran‑related conflict and regional supply‑chain strain. With limited slots and strong pressure to meet delivery schedules, shippers are turning to the canal’s auction system to move up in the queue, driving scarcity premiums higher and increasing wait times for non‑premium vessels.
In a striking sign of how congestion has become a pay‑to‑play issue, a liquefied petroleum gas tanker recently agreed to pay an extra $4 million in an auction to advance its transit, on top of sizable canal tolls that typically run into the hundreds of thousands of dollars. That figure marks a sharp increase from earlier March bids, which were still below $1 million, highlighting how quickly congestion pricing can spike when geopolitics and supply‑chain bottlenecks converge. The episode underscores that access to chokepoints like the Panama Canal is acting less like a fixed tariff and more like emergency‑style surge pricing, where urgency itself becomes the commodity being sold.
For US steel markets, the Panama logjam adds another friction point to imports that already contend with tariffs, longer routes, and tighter schedules. Many Asian and Latin American steel cargoes destined for the East Coast or Gulf Coast must pass through the canal, and extended waits or higher line‑jump costs can push up landed prices and discourage marginal shipments. At the same time, rerouting steel‑laden vessels around the canal at higher freight costs or via longer paths like the Suez Canal compresses the competitive edge of offshore suppliers, reinforcing the cost advantage of US‑produced steel and encouraging buyers to favor more reliable, shorter‑haul sources.
