Bitcoin Keeps Iranian Trade Flowing After Strait Clashes

Iranian companies have increased use of Bitcoin and other cryptocurrencies to send payments overseas following missile clashes near the Strait of Hormuz on May 4, 2026, and a missile strike on the Fujairah Oil Industry Zone. Sanctions, limits on Visa and Mastercard, and restricted SWIFT access have reduced formal payment options, prompting firms to convert rials into digital assets and transfer funds via digital wallets.

On May 4, Tehran reported it fired missiles at a U.S. Navy vessel near the strait; Washington denied a strike and described the incident as warning shots. The United States launched a naval operation called Project Freedom the same day, deploying destroyers, aircraft, drones and about 15,000 service members to escort ships through the shipping lane. A missile struck Fujairah’s oil storage and refining hub outside the strait, and Brent crude rose toward $120 while Bitcoin traded above $80,000.

Businesses facing limits on global card networks and bank messaging systems have turned to a simple process: convert rials held in local accounts into crypto, move funds wallet to wallet, and cash out through partners or exchanges in other countries. Funds are routed to recipients in Russia, Turkey, Gulf states and elsewhere, where local partners convert crypto back into local currency.

Digital-asset prices have become visible on Iranian exchange boards, and some higher-end Tehran restaurants accept crypto payments. Companies report using crypto for supplier payments and to pay for services that cannot be routed through formal banks.

Cheap domestic electricity, backed by Iran’s oil and gas supplies, encouraged rapid growth in Bitcoin mining. Ebrahim Mello, an Iran and Middle East expert and BRICS+ Consortium Business Council member, estimates the direct cost to mine one Bitcoin in Iran at roughly $1,000 to $1,500. Mining operations expanded into factories, private buildings, schools and places of worship, increasing pressure on the national power grid.

Officials sought to curb illegal and large-scale mining to ease power shortages. Observers link some of the most energy-intensive mining activity to networks tied to the Islamic Revolutionary Guard Corps; strikes in 2026 disrupted some of those operations, reducing mining demand and temporarily easing blackouts.

U.S. officials have described an enforcement effort called Economic Fury aimed at Iran’s shadow banking and logistics networks. The initiative targets access to crypto, shadow fleets, weapons procurement routes, funding channels for proxy groups and independent refineries that process Iranian oil outside official channels.

Cryptocurrencies remove certain immediate payment barriers but do not replace formal trade documentation and banking trails. Exporters and importers still need contracts, certificates of origin, labeling compliance and formal payment records to clear goods in markets such as Russia. Traders and analysts point to new risks from crypto use, including price volatility, counterparty uncertainty and potential exposure to further sanctions and enforcement actions.

For now, cryptocurrencies are being used to keep many payment flows moving while Iran’s access to traditional international finance remains constrained.
