Panama Canal
The Panama Canal is the artificial waterway across the Isthmus of Panama that connects the Atlantic and Pacific Oceans, letting ships pass between them without the long voyage around South America (Cape Horn). Opened in 1914 and run since 1999 by the Panama Canal Authority (ACP), it is one of the world's most strategically important shipping routes, using a system of locks to raise and lower ships across the continental divide.
The 2016 expansion added a new set of larger locks, creating the Neo-Panamax capacity that lets much bigger container ships transit — reshaping trade lanes (notably Asia to the US East Coast). The canal is central to US East Coast–Asia, and intra-American, trade, and its capacity, tolls, and constraints (including drought-driven draft restrictions in dry years) directly affect global shipping routing and cost. When the canal is constrained, ships reroute (via Suez or the Cape), rippling across supply chains. For anyone routing cargo between the oceans, the Panama Canal is a pivotal chokepoint. Understanding it — and its size limits (Panamax/Neo-Panamax) — is central to global shipping. It is one of the great arteries of world trade.

What did the 2016 Panama Canal expansion do?
It added larger locks, creating Neo-Panamax capacity so much bigger container ships can transit, reshaping trade lanes like Asia to the US East Coast.
Why can the canal's capacity change?
Drought can lower the lakes that feed the locks, forcing draft and transit restrictions in dry years, which pushes some ships to reroute.
