Highlights
- The Panama Canal is cutting daily ship crossings from 36 to 34 starting September 3, and to 32 from September 15.
- A severe El Nino-driven drought has lowered water levels in the canal's two feeder lakes, which supply the fresh water needed to operate its locks.
- The canal handles roughly 5% of global maritime trade and about 40% of US container traffic.
- Authorities have also lowered maximum vessel draft limits to conserve water as the restrictions tighten.
Crossings Cut in Two Phases
The Panama Canal Authority is cutting the number of daily ship crossings from 36 to 34 starting September 3, with a further reduction to 32 crossings taking effect September 15, as a severe El Nino-driven drought depletes the fresh water needed to operate the waterway's locks. The canal, which handles roughly 5% of global maritime trade and about 40% of all US container traffic, relies on rainwater collected in two artificial lakes to fill its lock chambers; persistently below-forecast rainfall in the canal's watershed has forced the phased restrictions, according to the Panama Canal Authority.
A Recurring Climate Risk for Global Trade
This year's El Nino event is shaping up as one of the strongest on record, intensifying the kind of water-supply stress that forced similar, even more severe restrictions in 2023 and 2024, when crossing limits fell as low as the mid-20s during the worst of that drought. Alongside the crossing-count reductions, canal authorities have also lowered the maximum permitted draft for larger vessels, a measure that limits how much cargo the biggest ships can carry through the canal even when granted a transit slot, compounding the capacity hit beyond the headline crossing numbers. France 24 reported that the Panama Canal Authority has framed the restrictions as necessary for the "long-term sustainability" of the waterway rather than a short-term emergency response, suggesting officials expect water-management constraints to remain a recurring feature of canal operations as El Nino cycles continue. Because the canal has no practical substitute route for much of the traffic that depends on it, every reduction in daily capacity forces shippers to either wait longer for a transit slot, pay premium fees for priority booking, or reroute around South America, adding significant time and fuel costs. The phased approach — cutting to 34 crossings before stepping down further to 32 — gives shipping lines a two-week window to adjust booking schedules rather than absorbing the full restriction in one abrupt move, though it still leaves little room for carriers already juggling other route disruptions this year.
Ripple Effects for Freight and Inflation
The timing adds another pressure point to global shipping capacity at a moment when freight markets are already navigating disruptions elsewhere. Reduced Panama Canal throughput tends to show up first in freight rates and transit-time data for trans-Pacific and intra-Americas routes, with knock-on effects for delivery schedules on goods ranging from consumer electronics to agricultural exports moving through the isthmus. For broader markets, tighter global shipping capacity is a mild inflationary input at the margin, adding to freight costs that eventually flow through to consumer prices — a dynamic that has also shown up in record US diesel refining margins amid a broader supply crunch and in the US strategic oil reserve falling to its lowest level since 1982. It also reinforces a theme investors have tracked all year: climate-driven disruptions to critical trade infrastructure are becoming a recurring, rather than one-off, source of supply-chain volatility that logistics and commodity markets have to price in as a standing risk.

What's Next
The next milestone is the September 15 step-down to 32 daily crossings, after which the Panama Canal Authority is expected to update guidance based on how the current El Nino event and lake water levels evolve through the fall. Shippers and freight-rate watchers will be tracking whether restrictions deepen further, as they did during the 2023-2024 drought when daily crossings fell into the mid-20s, or whether seasonal rainfall stabilizes water levels enough to hold the line at 32. Either outcome will shape trans-Pacific freight costs heading into the year-end shipping season.
FAQ
Why is the Panama Canal cutting daily crossings?
A severe El Nino-driven drought has lowered water levels in the two lakes that supply fresh water to the canal's locks, forcing the Panama Canal Authority to restrict traffic.
How many ships will be able to cross per day?
Crossings drop from 36 to 34 starting September 3, then to 32 from September 15.
How much global trade moves through the canal?
The Panama Canal handles about 5% of global maritime trade and roughly 40% of US container traffic.
Could restrictions get worse than 32 a day?
It's possible — during the 2023-2024 drought, crossings fell into the mid-20s at the worst point, though officials haven't signaled further cuts beyond September 15 yet.
