Armed forces spokesman rejects US demands on missile range

The central bank said the intervention is aimed at reducing demand in the open market and providing reassurance to businesses.

Analysts told the semi-official Fars news agency the injection could cut the dollar rate by up to 100,000 rials in the short term if delivered as cash or immediate transfers, though the effect would be limited if allocated through longer-term instruments.

Economists caution that such interventions often provide only temporary relief unless paired with structural reforms to boost exports, manage inflation and ensure transparency in foreign currency allocations.

The Iranian rial weakened on Sunday following the reimposition of snapback sanctions, trading at 111,400 per dollar, 130,370 per euro and 149,620 per pound on the open market.

A significant share of Iran’s trade is with countries that oppose the activation of the snapback mechanism and have formally expressed that stance, Iran's deputy foreign minister for economic diplomacy Hamid Qanbari said on Sunday.

He called the return of sanctions unenforceable and described the move as “psychological,” saying Europeans “tried to exaggerate.”

“Those who act on the basis of these psychological effects usually end up losing,” Qanbari added.

The snapback mechanism carries no significant effect compared to US sanctions aside from psychological pressure, parliament’s national security committee member Vahid Ahmadi said on Sunday.

“Today the power of resistance as a real and existing fact was able to stand against the arrogant power and its followers and defeat them,” Ahmadi added.

Media, journalists and social activists must help "neutralize the enemy’s role" after the return of UN sanctions, judiciary spokesman Asghar Jahangir said on Sunday.

“We will act against those who disturb the public’s psychological security,” Jahangir warned.

“Today’s cyberspace is full of rumors and lies,” he added.

Iran’s central bank will inject $500 million into the market to reduce pressure on the free dollar rate, state media reported on Sunday.

The intervention will begin Monday, according to local reports. Fars News affiliated with the Revolutionary Guards said if released in cash or ready transfers, it could cut the rate by 100,000 rials.

“But if most of the currency is only moved on paper or allocated as long-term transfers, its impact on market will be very limited, around 20,000 rials,” Fars said.
