The US dollar reached a record high against the Iranian rial in Tehran's free market on Saturday, trading at 1.941 million rials. This marks a significant increase of 32,000 rials, or 1.67%, from the previous day's unofficial closing rate, driven by mounting military and political tensions that have fueled a fresh sell-off in Iran's currency.
The rial's depreciation has been influenced by a series of geopolitical events. Following US and Israeli air strikes on Iran on February 28, the dollar climbed to 1.72 million rials. During the disruption caused by the conflict, demand for foreign currency temporarily weakened, causing the dollar to retreat to around 1.46 million rials.
Further volatility occurred after Donald Trump's threat on April 7 to launch air strikes against Iran's critical infrastructure. The dollar rebounded to 1.63 million rials before easing to approximately 1.525 million rials after a ceasefire was announced. The resumption of economic activity, combined with government estimates of $300 billion in wartime damage, renewed pressure on the foreign exchange market, pushing the dollar close to 1.9 million rials.
A brief period of restored confidence followed the signing of a "memorandum of understanding" between Tehran and Washington, which sent the exchange rate back to 1.53 million rials. However, renewed political tensions between the two countries soon reversed these gains, lifting the dollar back to around 1.7 million rials.
More recently, the rial has faced increased pressure following the launch of a fresh naval blockade of Iran and US air strikes on the country's southern regions. Washington stated these operations are intended to degrade Iran's military capabilities and prevent threats to shipping through the Strait of Hormuz.
Official data indicates that Iran's economy is already contending with severe price pressures. Annual consumer price inflation accelerated markedly, rising from 52.6% in December 2025 to approximately 68% in February 2026, and reaching 88.6% last month. This marks the highest inflation rate in Iran since the Second World War.
Persistently high inflation and rapid monetary expansion continue to erode the purchasing power of the rial. Geopolitical instability has further accelerated the currency's depreciation. A weaker rial consequently raises import costs, fuels inflation expectations, and drives prices higher, creating a cycle that places increasing strain on household incomes and the nation's broader macroeconomic stability.
