Dollar at 2.27 Million Iranian Rials as U.S. Blockade Continues

Key Facts

1The open-market dollar rate was 2,265,000 rials at 22:00 on September 5, 2026, an increase of 2.21% during the day.
2The dollar rate was 2,286,000 rials during the September 5 session, versus 2.20 million rials on September 2.
3CENTCOM resumed the blockade on July 14 at 16:00 U.S. Eastern Time.
4The Treasury Department began Operation Economic Outcast on August 24 as an economic campaign separate from the naval blockade.

The open-market dollar rate was 2,265,000 rials at 22:00 on September 5, 2026, an increase of 2.21% during the day. Market data recorded a rate of 2,286,000 rials during the session, reflecting weakness in the Iranian currency.

That extended a series of record currency levels. On September 2, the dollar traded at 2.20 million rials, nearly 10% above the previous record of 2.02 million on August 25, according to Tehran-market traders and inspected news-agency reports.

These figures refer to the open market, not a single administered rate. Iranians commonly quote everyday prices in tomans even though the rial is the official currency; 1 toman equals 10 rials. Currency comparisons therefore need to identify both the unit and the pricing venue.

The rial’s weakness comes as the United States maintains a naval blockade that is separate from its newer sanctions campaign. CENTCOM said it resumed blocking maritime traffic to and from Iranian ports and coastal areas on July 14 at 16:00 U.S. Eastern Time, following an initial phase from April 13 to June 18. It said the first phase redirected more than 140 vessels, disabled 9 and allowed more than 50 humanitarian-aid ships to pass.

CENTCOM provided an enforcement example on July 15, when it said U.S. forces disabled an unladen oil tanker heading toward an Iranian port after the vessel ignored warnings. The incident verifies military enforcement of the blockade, but it does not establish that a new naval action on September 5 directly caused that day’s currency movement.

The Treasury Department began Operation Economic Outcast on August 24 as an economic campaign involving several government agencies and targeting financial and commercial networks linked to Iran. It is not the official name of the naval blockade or a Navy-only mission.

The rial remains exposed to pressure from war, sanctions and constrained foreign-currency inflows, but a single day’s move cannot isolate each factor’s effect. The next signals will come from open-market rates, blockade-enforcement notices and further Treasury measures, with correlation distinguished from direct causation.
