Why has the Panama Canal Authority suspended bookings for Panamax-class locks, and what is the immediate operational impact?

The Panama Canal Authority has suspended daily auctions for Panamax-class locks in 'period three' starting July 25 due to low and projected water levels at Gatun Lake, compounded by concerns over a potential El Niño weather pattern that historically reduces freshwater supply to the canal. As a direct result, daily booking capacity has been reduced from 36 to 34 vessels.

How does the Panama Canal's current restriction relate to broader global shipping disruptions mentioned in the article?

The Panama Canal's tighter access is occurring alongside major disruptions at other critical maritime chokepoints: vessel traffic through the Strait of Hormuz has nearly halted due to the Iran-US war and attacks on ships, while Yemen’s Iran-backed Houthi militants have threatened shipping via the Bab el-Mandeb Strait in the Red Sea—collectively intensifying pressure on global trade flows.
