Panama Canal Caps Daily Transits as El Niño Shrinks Water Supply

Officials say the limits conserve reservoir water that supports canal operations, protect Panama City's drinking supply, signal higher shipping costs, longer transit waits

Overview

  • The Panama Canal Authority announced Thursday that daily passages will be cut from 36 to 34 starting in early September and to 32 from September 15, with Neopanamax limited to nine slots and Panamax to 25 then 23.
  • The authority reported rainfall from May through August about 34% below the historical average and watershed inflows roughly 44% below normal, citing a strong 2026–2027 El Niño as the driving cause.
  • Planned reductions to maximum authorised drafts were postponed, moving a Neopanamax cut to 14.63 metres to September 2 and a further cut to 14.48 metres to October 1 to ease near-term cargo limits.
  • Shipping analysts expect tighter daily slots to push up transit premiums, lengthen queues and prompt some vessels to reroute via the Suez Canal or around the Cape of Good Hope, raising freight costs and delivery times.
  • The move reverses a May assurance that no restrictions were planned, reflects lessons from the 2023–24 drought, and leaves open additional measures if rainfall and inflows do not recover.
