Iran shut the Strait of Hormuz this week in retaliation for US military strikes, blocking roughly a fifth of the world's oil supply and sending both traditional and crypto markets into a tailspin. The move, one of the most aggressive escalations in years, triggered a broad flight from risk assets.
Why the strait matters
The Strait of Hormuz is a narrow passage between the Persian Gulf and the Gulf of Oman. About 20% of global oil transits through it daily. Closing it doesn't just squeeze supply — it injects uncertainty into every market that depends on stable energy costs. That includes crypto mining, which is heavily sensitive to electricity prices.
Oil surges, crypto slides
The immediate effect was a spike in crude prices and a sharp drop in cryptocurrencies. Bitcoin and other major tokens fell as investors dumped volatile assets. The selloff was broad: stablecoins saw elevated trading volumes as holders moved to cash. The correlation between crypto and oil isn't perfect, but in a geopolitical shock, both move — just in opposite directions.
What traders are watching now
The blockade has no fixed end. Iran says it will lift the closure only if the US halts its attacks. Diplomats are scrambling, but no talks have been announced. For crypto traders, the key question is duration. A short blockade might mean a quick bounce. A prolonged one could push energy costs higher, squeezing miners and weighing on prices.
As of this afternoon, oil tankers are rerouting around the Arabian Peninsula — a detour that adds days and costs. Markets are pricing in continued chaos, and no one is calling a bottom yet.
