Germany’s top financial regulator, the Federal Financial Supervisory Authority (BaFin), declared the Frankfurt branch of Iran’s state-owned Bank Sepah insolvent on September 10. The decision initiated a formal liquidation process under Germany’s statutory deposit-protection law after the branch could no longer meet its obligation to repay customer deposits.

The failure was a direct consequence of EU sanctions that severed the branch’s access to European payment infrastructure. A Frankfurt court appointed an insolvency administrator on the same day to oversee the wind-down of the branch’s assets and resolve outstanding claims.

The branch held approximately €50 million in total assets and served only 11 depositors, making it one of the smallest bank failures BaFin has handled.

A collapse years in the making

Bank Sepah’s problems with Western regulators date back nearly two decades. Founded in 1925, the Iranian lender was added to international sanctions lists in January 2007 over alleged links to Iran’s military procurement and nuclear programs.

Those initial restrictions were gradually tightened as successive rounds of US and EU sanctions increasingly isolated Iranian financial institutions from the global banking infrastructure used to process cross-border transactions.

BaFin had also previously raised concerns about the Frankfurt branch’s compliance posture. In 2023, the regulator fined Bank Sepah €27,500. Although relatively modest, the penalty highlighted the growing supervisory pressure on the institution.

The immediate trigger appears to have been a recent US campaign to increase pressure on Iranian financial institutions, adding to the EU’s existing restrictions. With its access to European payment systems effectively cut off, the Frankfurt branch could no longer process transactions or honor withdrawal requests from its limited depositor base.

What happens to depositors

The 11 depositors affected by the closure have been instructed to submit claims to Germany’s statutory deposit-protection scheme, the Entschädigungseinrichtung deutscher Banken (EdB). Under German law, each depositor is eligible for a maximum payout of €100,000.

BaFin has confirmed that the insolvency poses no systemic risk to Germany’s or the European Union’s broader financial systems.

Wider sanctions pressure on Iranian banks

The insolvency is part of a broader effort by Western financial authorities to restrict Iranian institutions’ access to the global financial system. As a state-owned bank with historical connections to Iran’s defense establishment, Bank Sepah was among the first Iranian banks designated under both US and EU sanctions regimes.

Its Frankfurt branch was one of the few remaining physical presences of Iranian banking in a major European financial center. The current legal proceedings are limited specifically to the German branch and do not affect Bank Sepah’s overall operations in Iran.
