The Panama Canal will reduce daily vessel transits from 40 to 34 starting this week and to 32 by mid-September due to low water levels linked to El Nino. At the same time, disruptions in the Strait of Hormuz have increased demand for the canal, which handles 5 percent of global maritime trade and a large share of US container traffic. The measures are expected to raise transit costs and affect freight rates for several routes.
What limits are being placed on Panama Canal traffic?
The Panama Canal Authority announced that vessel passages will drop to 34 per day from September 4. The cap will fall further to 32 on September 15. These steps respond to reduced rainfall, which is 34 percent below average from May to August, worsened by the El Nino phenomenon. Additional water-saving steps include lower maximum draft limits for larger ships.
How important is the Panama Canal to global and US trade?
In 2024 the canal carried $270 billion in cargo. It accounts for 40 percent of US container traffic and 5 percent of worldwide sea trade this year, with 70 percent of that volume linked to the United States. Container ships and liquefied petroleum gas carriers have driven recent growth.
Why has demand risen during the Hormuz crisis?
Reduced oil exports through the Strait of Hormuz have led buyers to seek supplies from the Americas. US crude exports through the canal rose 46 percent year-on-year to 61.6 million metric tonnes in the second quarter of 2026. Brazil, Argentina and Guyana also recorded record oil shipments via the waterway.
What are the expected effects on shipping costs?
Higher demand has already pushed auction prices for transit slots from an average of $55,000 to three times that level. One vessel paid a record $5.3 million in early September. Analysts at BIMCO expect some cargoes to reroute around the Cape of Good Hope, raising fuel and time costs. Container services from Asia to the US east coast and LPG exports from the US Gulf to Asia and South America are likely to face the largest increases in freight rates.
Frequently asked questions
Why is the Panama Canal lowering daily vessel limits?
Lower rainfall from the El Nino weather pattern has reduced water levels, requiring conservation measures that limit the number of ships that can transit each day.
Which trade routes are most affected?
Container cargo from Asia to the US east coast and LPG shipments from the US Gulf to Asia and western South America face the greatest pressure from higher transit costs and possible rerouting.
Has traffic through the canal increased this year?
Yes. More than 10,000 vessels passed through in the nine months to June, up 5.2 percent from the prior year, with total tonnage 7.2 percent higher.
Key takeaways
- Daily vessel limit falls to 34 from September 4 and to 32 from September 15.

- US crude exports via the canal reached 61.6 million metric tonnes in Q2 2026.
- Transit slot auctions have risen to three times earlier averages.
- Some vessels may divert around South Africa, increasing journey times and costs.
