Global Trade Grows but Remains Vulnerable to War and Geopolitics

The global system of container ships and tankers that move tens of billions of dollars of products around the world each day mostly functions fluidly and without notice. But in a few parts of the world, shipping lanes shrink to narrow straits or canals, geographical choke points where an isolated disruption can threaten to throw much of international trade out of whack.

One of those is the Taiwan Strait, a 100-mile-wide strip of water between Taiwan and mainland China, which has become a critical shipping lane for countries across the globe.

New research from the Center for Strategic and International Studies, a Washington think tank, has found that the strait is a conduit for more than a fifth of the world’s seaborne trade, with $2.45 trillion worth of energy, electronics, minerals and other goods transiting the channel in 2022, the most recent year for which data is available.

The findings are significant given that the strait is at the center of a geopolitical dispute between Taiwan and China, which views the island as part of its territory. A blockade or military action from China that halted traffic in the strait could have dramatic implications for the global flow of goods, and the Chinese economy in particular, the researchers say.

The estimates come at a moment when geopolitics is upending years of relative complacency about global trade dynamics. Wars in Ukraine and the Middle East, as well as pandemic-era lockdowns, have reshuffled global trade patterns and alerted consumers to the idea that disruptions in one part of the world can directly affect economic activity in another.

In a report also released Thursday, the World Trade Organization said that the pace of global trade has been ticking up, but that rising geopolitical tensions and uncertainty over economic policy could drag it down.
