Background
The preferential exchange rate was a multi-tiered rate, set below the open market, that the government allocated from 2018 (1397) for imports of essential goods and medicine; because of its large gap with the open-market rate, the mechanism became notorious for large-scale rent-seeking and goods diversion, and was gradually restricted and merged in later years. Hemmati's emphasis today on not returning to it responds to renewed pressure after the open-market dollar jumped nearly 9% in a single week, June 27 to July 1 (from 161,500 to about 176,000 tomans, per Sahmino's Market Pulse). At the same time, Sahmino had previously reported that the US Treasury's General License X, issued June 22, 2026, permitted Iranian crude, petrochemical, and petroleum product sales for the first time in over four decades, through August 21, 2026, potentially generating up to $3.06 billion in foreign currency revenue; part of the central bank's new reserve buildup is attributed to that license.
