When Money Collapses So Does Consent: Iran’s Currency Crisis and Bazaar Behavior

Iran’s latest wave of protests was not sparked by ideology, elections, or identity. It was sparked by money — or rather, by the sudden realisation that money no longer works.

In late December 2025, the Iranian rial collapsed to around 1.42 million per US dollar, a historic low that rendered everyday commerce incoherent. Headline inflation reached 42 percent, with point-to-point inflation surging to 53 percent. Food prices rose more than 72 percent year-on-year, and wages lost value faster than they could be spent. What followed was not abstract anger but immediate revolt — beginning in Tehran’s Grand Bazaar and rapidly spreading to Isfahan, Shiraz, Mashhad, and Yazd.

This matters because in Iran, when the bazaar closes, the system is already in trouble.

The Bazaar as Economic Barometer

On December 28, merchants in Tehran’s Grand Bazaar shuttered their shops and chanted against economic mismanagement. Within 48 hours, similar scenes unfolded nationwide. Security forces responded with tear gas, but the symbolism was already irreversible. Historically, bazaari mobilisation has marked regime-level crises — from the Constitutional Revolution of 1906 to the overthrow of the Shah in 1979.

Unlike students or urban youth, merchants are not habitual protesters. They sit at the intersection of trade, credit, and social stability. When they revolt, it signals not merely political dissent, but the collapse of price signals, contracts, and trust.

What distinguishes 2025 from earlier protest waves is the social base. The unrest of 2018 was driven by fuel prices and the urban poor. The protests of 2022 were rooted in social freedoms and youth mobilisation following Mahsa Amini’s death. This wave is different: it is led by the commercial middle — the class that depends most on monetary stability and that historically anchors regime legitimacy.

Exchange Rates as Political Rationing

The rial’s collapse did not occur overnight. It fell from roughly 430,000 per dollar in 2022 to over 1.4 million in 2025, reflecting years of structural erosion. Sanctions, oil revenue volatility, the June 2025 war with Israel, and geopolitical isolation matter — but they do not explain everything.

Equally corrosive has been Iran’s multi-tiered exchange-rate system, which has turned monetary policy into a mechanism of political allocation. Official, semi-official, and free-market rates coexist, granting privileged access to cheaper dollars for state-linked firms and insiders while exposing ordinary merchants to brutal market pricing. The result is not merely inflation, but institutionalised rent capture.

For bazaar traders, the problem is not just that prices rise — it is that competitors with political connections can survive currency swings that others cannot. This converts economic hardship into perceived injustice, a far more combustible force.

Dollarisation and the Death of the Rial

As confidence in the currency evaporates, Iranians have adapted in predictable ways. Informal dollarisation from below is accelerating: rents, appliances, dowries, and even wholesale food contracts are increasingly priced in dollars or gold. Rial wages, paid with delay and eroded by inflation, have become symbolic rather than functional.

This behavioural shift is critical. Once a population abandons its own currency in practice, monetary stabilisation becomes vastly harder. The rial is no longer merely weak — it is losing its role as a unit of account, a store of value, and a social contract.

Inflation as an Intergenerational Crisis

Inflation in Iran is often discussed as a macroeconomic problem. In reality, it is becoming an intergenerational one. Small businesses cannot pass shops or savings to children when inventories are wiped out by exchange-rate swings. Young Iranians face a labour market where wages lag far behind prices and asset ownership becomes impossible.

This explains why an initially economic protest cycle rarely stays confined to economics. When families lose the ability to transmit stability across generations, legitimacy erodes faster than repression can contain it.

Guns, Subsidies, and Monetary Exhaustion

Iran’s leadership faces a narrowing set of fiscal choices. Regional conflict and military commitments — intensified by the twelve-day war with Israel in June 2025 and ongoing proxy engagements — absorb resources that might otherwise stabilise prices or protect real incomes. The September 2025 reimposition of UN sanctions through the snapback mechanism further constrained external financing. Subsidies are trimmed, deficits widen, and the central bank fills the gap through monetary expansion.

The result is a quiet but relentless tradeoff: external confrontation versus internal currency stability. No amount of personnel reshuffling can resolve that tension.

The resignation of Central Bank Governor Mohammad Reza Farzin was intended as a signal of accountability. Instead, it underscored how little policy space remains. When Farzin took office in 2022, the rial traded at 430,000 to the dollar. Personnel changes cannot compensate for sanctions-constrained revenues, fiscal exhaustion, and a politicised monetary system.

A Regional Warning, Not an Iranian Exception

Iran’s crisis is extreme, but it is not unique. Across the Middle East, currency instability has become a recurring trigger of unrest: Lebanon’s lira collapse destroyed savings, with the currency losing more than 98 percent of its value since 2019; Syria’s pound freefall hollowed out wages; Egypt’s managed depreciations have strained social tolerance.

The lesson is consistent. Currency stability is not a technical indicator — it is a pillar of political consent. When money stops making sense, repression cannot restore order because order depends on predictability, not fear.

The Closing Window

Iran’s protests are not revolutionary — yet. But they are systemic. Bazaar-led unrest historically signals that economic breakdown has reached the commercial core of society. Once that happens, temporary crackdowns buy time but not resolution.

Stabilising the rial would require restoring external economic channels, rationalising exchange rates, curbing fiscal monetisation, and confronting the economic costs of permanent confrontation. Without such changes, protests may subside temporarily — but the next collapse will come faster, deeper, and with fewer shock absorbers left.

History suggests that revolutions do not begin when people are angry. They begin when prices stop making sense.

In Iran today, nothing does.
