BBC Radio 4: The World this Weekend - Shutting the Strait of Hormuz

We're already seeing signs of a real squeeze inside Iran, and this is not only the consequence of the blockade and certainly not of the six-week war - Iran entered the war from a position of financial weakness and uncertainty. The protests that erupted on the streets of Tehran and in many parts of Iran from December and peaked in early January were driven by currency depreciation and the threat of higher unemployment and inflation. So there was already a contraction in the economy. That was the direction of travel. Now the double blockade that we're seeing in the Strait of Hormuz affects deeply Iran's ability to export its oil products."
