Event guides
The events that move markets
A strait closing, a canal running dry, a cartel changing quotas — the things that reprice portfolios fastest and that brokerage apps say nothing about. Each guide explains what the event is, what history says about it, and which sectors it touches, argued from both sides.
Maritime chokepoints
Strait of Hormuz
About a fifth of the world's oil through a 21-mile channel. Whether it can actually be closed, and why disruption matters more than closure.
Suez Canal
Roughly a third of global container traffic. What the Ever Given proved, and why Suez transmits through freight rather than fuel.
Red Sea & Bab el-Mandeb
The corridor that feeds Suez — and the clearest modern case of a chokepoint disrupted without ever being closed.
Panama Canal
The only major chokepoint whose constraint is rainfall. How lake levels become transit caps, and why US routes feel it first.
Taiwan Strait
The semiconductor chokepoint — and the one where the exposed sector is technology rather than energy or freight.
Strait of Malacca
The busiest chokepoint nobody talks about: 1.7 miles at its narrowest, and the "Malacca dilemma" it creates.
Bosphorus & Turkish Straits
The grain chokepoint, running through central Istanbul under a 1936 convention that still governs who may pass.
