Dollar Pauses, Prices Don’t

The US dollar exchange rate was around 260,000 rials last March. Now it still hovers around this figure and some days it dips even lower, registering a zero percent growth. 
Many people and officials believe that whenever the exchange rate increases, all other goods and services follow suit. Therefore, the consumer price index in the Iranian year 2021-22 should have been zero as well, but this has not been the case.
Amin Kavee, an economic researcher, examines this anomaly in an article for the Persian economic daily Donya-e-Eqtesad.
