Services at Iran's Bank Sepah and Bank Melli were disrupted on Tuesday, from approximately 2 a.m. local time, the Islamic Revolutionary Guard Corps-linked Fars News Agency reported.
This included disruptions to Bank Sepah's mobile services and other internet services being disrupted, and ATM, as well as other points of service at Bank Melli suffering disruptions.
Tasnim News Agency, another IRGC-linked outlet, cited a statement from Bank Melli, saying that investigations and measures are being taken to resolve the disruptions.
An earlier statement from Iran's Central Bank denied a statement on social media attributed to the Central Bank governor, calling the text an "unreliable fake," according to a Tasnim report earlier on Tuesday.
The Central Bank at the time claimed that services at Sepah and Melli banks are "being provided without any restrictions and [functioning] as usual."
Bank Sepah is a state-owned institution sanctioned by the US in 2007 for suspected ties to Iran's nuclear program.
The bank was the target of a cyberattack, reported on June 17, 2025, amid the Israel-Iran War.
Bank Melli is also a state-owned institution and is one of the largest banks in the Middle East. It was sanctioned by the US and EU in 2007 and 2008, respectively.
NetBlocks denounces Tehran's ongoing enforced internet outage
Meanwhile, NetBlocks, which monitors internet traffic and activity across the world, denounced the Islamic regime's ongoing enforced internet outage across Iran on Tuesday, stating that after 240 hours of outages, it is "among the most severe government-imposed nationwide internet shutdowns on record globally, and the second longest registered in Iran after the January protests, with the country having spent a third of 2026 offline."
