The Fall of the Rial: Tehran’s Street Currency Market Reveals the Depth of Iran’s Economic Crisis

The Rial’s Long Decline

The current crisis did not begin in September 2026.

The rial’s decline has been a long-running process.

Over the years, repeated rounds of sanctions, inflation, political instability and economic disruption have weakened the currency.

The exchange rate has moved through increasingly extreme levels.

A rate that once would have been considered an economic emergency eventually became normal.

Then another threshold was crossed.

Then another.

The progression illustrates an important feature of currency crises: they are rarely defined by a single day.

Instead, they are often characterized by a sequence of deteriorating expectations.

People gradually lose confidence.

Businesses gradually adapt.

Prices gradually rise.

Foreign currency becomes increasingly important.

And the domestic currency gradually loses its role as a reliable store of value.
