On Monday, August 24, Treasury Secretary Scott Bessent introduced Washington’s new marketing campaign towards Iran’s regime: Operation Financial Outcast. The target, in his phrases, is “to sever each financial lifeline that sustains this tyrannical regime till Tehran stands alone.”
Greater than 60 entities, people and vessels had been designated within the first spherical. However amongst all of the establishments Bessent named, one stood out: Financial institution Melli, one of many Iranian state’s largest banks, was the one one whose each international department, he stated, “should be shuttered and darkish.”
Bessent additionally issued a warning to anybody tempted to assist: “Any entity that facilitates cash laundering on behalf of Iran can be faraway from the U.S. greenback system. The clock simply began ticking.”
Britain has made a narrower accusation. It designated Financial institution Melli’s London subsidiary below its Iran nuclear sanctions regime, and nothing within the financial institution’s UK filings alleges cash laundering. Two governments reached the identical financial institution by totally different authorized routes.
Eleven months after Britain sanctioned it, Melli Financial institution plc nonetheless holds a British banking license. It nonetheless seats a board, nonetheless meets a payroll in London, nonetheless information audited accounts. Each asset frozen, each new buyer barred, and it stays a financial institution. Shuttering it’s a separate act, and Britain is the one authorities that may carry out it.
A British financial institution, owned by the Islamic Republic
Financial institution Melli operates branches and subsidiaries in about ten nations and territories, from the United Arab Emirates to Germany. Its London operation is an organization in its personal proper: Melli Financial institution plc is registered in England, with a full banking license from Britain’s monetary regulators, the identical authorities that supervise Barclays and HSBC.
Each share of it belongs to Financial institution Melli Iran, which belongs to the Iranian state. Till April 2026, the chairman of its London board was concurrently the chief govt of the mum or dad financial institution in Tehran.
Being a British firm comes with a British obligation: publishing audited monetary statements for anybody to learn. The newest set, 54 pages overlaying 2025, was filed with the UK company registry in June. It quantities to one thing uncommon: an inside view of a regime-owned financial institution because the partitions shut in.
The accounts additionally go away little question about what the financial institution was for. Its core enterprise for 4 many years was financing commerce between Iran and Europe, primarily by way of letters of credit score, the usual instrument that ensures cost in cross-border commerce.
The financial institution’s personal filings name Iran its “area of interest market” and say about 92% of its income was earned in euros, in what it calls the Eurozone–Iran commerce hall. A €363 million establishment, with €258.8 million in capital that finally belongs to the Iranian state, existed contained in the British monetary system to maintain cash flowing between Iran and Europe.
And enterprise was good, proper as much as the tip. In 2024 the financial institution recorded its greatest revenue since 2014, €2.4 million. In 2025 its charge revenue from commerce finance surged one other 71%, a increase reduce brief in late September, when the sanctions arrived.
What a severed lifeline seems to be like
In August 2025, Britain, France and Germany triggered the UN “snapback.” The restored sanctions took impact on September 28. The subsequent day, Britain and the European Union sanctioned Melli Financial institution plc itself.
Since then, the financial institution has been forbidden from writing a brand new mortgage or taking a brand new buyer. Its personal accounts describe what stays because the “orderly administration” of present belongings and liabilities in a managed, non-trading surroundings.
The numbers present what meaning in observe:
- The financial institution holds about €98 million in deposits that it isn’t licensed to repay, at the same time as €88 million of them come due. Most of that cash belongs to Iranian monetary establishments which are themselves below sanctions. Sanctioned depositors, sanctioned financial institution: the cash is solely locked between them.
- €71 million of the financial institution’s personal cash is caught at different banks that maintain its accounts, unavailable “resulting from exterior restrictions.” What the financial institution can really attain is about €30 million.
- Iranian banks owe it €36.5 million in funds that fell overdue throughout 2025. A yr earlier, that determine was zero.
- Almost three-quarters of its belongings, €259.9 million, are claims on Iran, principally cash owed by Iranian banks. These are the belongings that need to go someplace if the financial institution stops present.
The financial institution’s British auditor has formally warned of “materials uncertainty” over whether or not it could proceed as a going concern. Its Hong Kong employees left in January when a cost license for his or her salaries didn’t arrive in time. Layoffs started in London in December.
The Tehran consultant workplace is closing. 4 board members have departed in little over a yr; three stay. But seniority nonetheless pays: complete board compensation rose to €905,000 in 2025, and the highest-paid director obtained a €615,000 package deal together with rented housing, an organization automotive and personal medical insurance, in the identical yr the financial institution booked €1.26 million in severance prices.
What retains the lights on in any respect is a permission slip. A normal license from the UK Treasury, issued three and a half weeks after the designation, permits precisely 4 sorts of funds: wages and severance for its UK-based employees and administrators, their pensions, IT payments, and the accountant’s charge.
Each month the financial institution should report each cost it makes, line by line, to the Treasury. Even its legal professionals require a separate license; authorized {and professional} prices jumped 57% final yr to simply over €1 million, greater than 5 instances the financial institution’s whole 2025 revenue of €181,000, itself down 92% from the yr earlier than.
Britain’s determination
On August 25, the day after Bessent spoke, Britain’s Chancellor John Healey welcomed Operation Financial Outcast, noting that Britain has imposed greater than 240 sanctions on Iran since Labour took workplace in 2024 and pledging to work with Washington on financial strain.
Britain had sanctioned Melli Financial institution plc eleven months earlier on grounds of its personal, below a nuclear regime unrelated to the cash laundering Bessent alleges. The endorsement solutions a special query: on the target, Britain is with Washington.
That query has been open because the conflict started, with American officers making little secret of their view that British cooperation has run behind Washington’s expectations. Melli Financial institution plc presents an inexpensive option to shut the hole. The financial institution has been barred from buying and selling since September. Its depositors are overwhelmingly sanctioned Iranian establishments. Its employees is already leaving. Letting the license expire fingers Washington a closed financial institution at nearly no price to Britain.
Britain sanctioned the financial institution in September 2025, and weeks later the Treasury granted it Interim Requirements Common Licence INT/2025/7628424. Renewal adopted in April 2026. Each British and European sanction on Melli Financial institution plc that’s in pressure immediately was in pressure then. Washington introduced Operation Financial Outcast 4 months later, on August 24. The license expires on October 22.
The financial institution anticipated the signature to come back once more. Citing authorized recommendation, its accounts say it anticipated renewal, and it behaved accordingly: it had added a brand new board member weeks earlier than snapback, signed a brand new Hong Kong workplace lease a month after being sanctioned, and deliberate to rehire employees there by this summer season.
Its report comprises no wind-down plan, no closure situation, and never a phrase about what occurs to the €98 million in deposits or the €258.8 million in capital if the license lapses.
If the license lapses, the financial institution can not lawfully pay its employees or its auditors, and an English firm that can’t pay its auditors doesn’t stay a going concern. Insolvency would put Melli Financial institution plc in entrance of a British court docket, which must determine what turns into of €98 million owed principally to sanctioned Iranian banks and €258.8 million of capital belonging to the Iranian state.
Neither the financial institution nor the Treasury has stated what that course of would appear to be. The issue of it’s the greatest motive the Treasury has to signal once more. Insolvency would launch nothing, although: sanctioned cash stays frozen whoever administers it.
A freeze is a pause, and this financial institution has lived by way of one. The European Union sanctioned Melli Financial institution plc in 2008. The nuclear settlement lifted these sanctions in 2016, and the financial institution went again to financing Iranian commerce, on its option to its greatest yr since 2014. Every part imposed on it since 2025 might come off the identical manner, in a deal. Closure ends that.
A surrendered license, distributed capital and a dispersed employees go away nothing to restart, and any future British authorities minded to have this financial institution again must authorize an Iranian state-owned financial institution from the start.
That’s what makes this obscure financial institution in London price watching. Operation Financial Outcast rests on a declare {that a} regime’s monetary lifelines may be reduce in observe. Melli Financial institution plc exhibits the equipment working finish to finish: worldwide snapback, allied designations, a frozen stability sheet, a departing employees, and one administrative determination standing between a regime-owned financial institution and closure.
On October 22 the Treasury has two choices. It will probably signal the license once more and maintain Melli Financial institution plc alive, or let it lapse and shut a British financial institution owned by the Iranian state. Bessent stated the clock simply began ticking. In London, it already has an alarm set.
