The gist
Iran plans fees on ships in the Strait of Hormuz amid fiscal strain. The move could escalate US-Iran tensions and disrupt global oil trade.
Background
The Strait of Hormuz is a critical maritime chokepoint for global oil and gas exports. Tensions have been high since the Iran war began in late February, with the US and Iran exchanging hostile rhetoric and imposing sanctions. Iran has threatened to close the strait, but traffic has actually increased nearly 400% in two weeks, partly due to a US-backed corridor. Now Iran plans to impose fees on ships, which could be a concrete step towards using the strait as leverage.
