The passageway accounted for 40 percent of all US container traffic and 2.5 percent of all global sea trade.This year, according to the Panama-canal-authority" class="entity-link entity-organization" data-entity-id="183780" data-entity-type="organization">Panama-canal" class="entity-link entity-location" data-entity-id="8414" data-entity-type="location">Panama Canal Authority, that has risen to 5 percent of all global sea trade, with 70 percent destined for or originating in the US.Has traffic in the Panama-canal" class="entity-link entity-location" data-entity-id="8414" data-entity-type="location">Panama Canal been increasing this year?Yes.At the end of June, Panama-canal" class="entity-link entity-location" data-entity-id="8414" data-entity-type="location">Panama Canal administrator Ricaurte Vasquez Morales said more than 10,000 vessels had transited the canal over the previous nine months, up 5.2 percent from the same period a year earlier, driven largely by increases in container ships and liquefied petroleum gas (LPG) carriers.He also said the canal’s total vessel tonnage was 7.2 percent higher during the same period.How has the Hormuz crisis contributed to this?With Gulf producers unable to export as much oil through the Strait of Hormuz as they did before the war – about 20 million barrels of oil per day (bpd) – countries are increasingly turning to North and South America to make up supplies, driving more traffic towards the Panama-canal" class="entity-link entity-location" data-entity-id="8414" data-entity-type="location">Panama Canal.The effect has been particularly pronounced for crude oil exports from the United States, which leapt by 46 percent year-on-year to a record 61.6 million metric tonnes in the second quarter of 2026, according to global trade intelligence firm Kpler – equivalent to about 450 million barrels in total, or an average of about 5 million bpd.Brazil, Argentina and Guyana have all posted record shipments of oil so far in 2026.What impact will the new Panama restrictions have?The rise in cargoes needing to be shipped through the canal is already creating a bidding war for transit slots in the canal.While average auction prices for transit slots were $55,000 between October last year and February this year, the recent surge in demand has caused those prices to jump three-fold, according to the canal’s authority.One South Korean ship paid a record $5.3m to pass through the canal on September 1, according to Bloomberg News.Niels Rasmussen, chief shipping analyst at the Baltic and International Maritime Council (BIMCO), an international shipping association, said the canal’s new restrictions will put more pressure on shipping, pushing some vessels to reroute and make longer, more costly journeys around the Cape of Good Hope in South Africa.“Reduced cargo capacity, combined with higher auction prices for transit slots, is likely to push freight rates higher,” Rasmussen told Al Jazeera.Container cargo moving from Asia to the US’s east coast, as well as LPG exports from the US Gulf to Asia and the western coasts of Central and South America, could be particularly affected, he added.
