Key Insights Crypto News: Iran eased currency rules as sanctions restricted banking access. Bitcoin and USDT gained a larger role in cross-border settlement. U.S. authorities continued target
Iranian authorities relaxed foreign-exchange controls as businesses increasingly used digital assets for overseas trade under sanctions. The Crypto News development brought Bitcoin and USDT deeper into Iran’s payment channels as conventional banking access narrowed.
The Financial Times reported on Sept. 9 that Iran’s central bank had quietly allowed greater flexibility around export proceeds. The policy gave companies more room to settle transactions through domestic crypto exchanges instead of official currency channels.
Iran’s shift mattered because U.S. authorities had simultaneously expanded sanctions against its financial and commercial networks. That tension placed crypto at the center of a widening contest between payment access and sanctions enforcement.
The Financial Times said Iranian officials had pushed companies to return overseas earnings through several approved routes. One option involved settling transactions through domestic digital-asset platforms using Bitcoin and Tether’s USDT.

The Financial Times said authorities had become less focused on the original source of repatriated funds. That approach gave businesses greater flexibility when bringing foreign earnings back into Iran.
Iran still faces broad restrictions across conventional financial networks. The U.S. Treasury’s Office of Foreign Assets Control said Iranian digital-asset exchanges qualify as Iranian financial institutions.
The agency’s April guidance said U.S.-controlled property tied to such exchanges remained blocked. That rule placed Iranian crypto platforms within the same sanctions framework covering other Iranian financial institutions.
Blockchain data showed Iran already had a large domestic crypto economy before the latest policy adjustment. TRM Labs estimated Iranian crypto activity reached roughly $10 billion during 2025.

Chainalysis produced a lower estimate using its own attribution methodology. The firm measured Iran’s crypto ecosystem at more than $7.78 billion during 2025.
The difference reflected separate tracking methods and attributed address sets. Still, both datasets showed sustained digital-asset usage inside Iran during prolonged financial restrictions.
Chainalysis also said addresses linked to the Islamic Revolutionary Guard Corps received over $3 billion during 2025. Those addresses represented more than half of Iran-related value received during the fourth quarter.
That activity drew direct U.S. enforcement. The Treasury sanctioned two digital-asset exchanges on Aug. 7 over alleged links to Iranian state networks.
Treasury said the exchanges helped move funds through lightly regulated platforms and international corporate structures. The department alleged those networks supported sanctions evasion and Islamic Revolutionary Guard Corps-linked financing.
Washington had already broadened pressure on Tehran before the latest currency-rule shift. Treasury Secretary Scott Bessent launched Operation Economic Outcast on Aug. 24.
Bessent said the campaign targeted Iran’s financial connections and foreign economic partners. Treasury also warned that activity involving digital assets could expose foreign entities to secondary sanctions.
The Office of Foreign Assets Control separately stated that Iranian digital-asset exchanges remained blocked under existing regulations. That position limits direct access to U.S.-linked financial infrastructure regardless of Iran’s domestic policy.
The enforcement campaign expanded again on Sept. 8. Treasury sanctioned 36 targets tied to Iran’s aviation sector and supporting commercial networks.
That action did not target Bitcoin or USDT directly. However, it further restricted conventional channels that Iranian companies could use for international commerce.
Crypto therefore offered settlement flexibility while creating new compliance exposure. Public blockchains can move value without correspondent banks, but transaction histories remain visible to blockchain investigators.
USDT also carries issuer-level controls that Bitcoin does not. Tether can freeze tokens at specific addresses, limiting the stablecoin’s usefulness when issuers identify sanctioned exposure.
Iran’s latest policy therefore widened access to digital settlement without removing sanctions risk. The policy also showed how trade restrictions can shift transaction routes without eliminating enforcement exposure.
Firms still face sanctions screening, counterparty risk and issuer controls. The next test will be U.S. enforcement against businesses using Iranian exchanges under the expanded campaign.
