Three Days On, Britain Has Not Said Whether It Will Freeze a Pound of al-Abyari’s Money

The Office of Foreign Assets Control’s 23 July action named seven targets — four individuals and three entities — under Executive Order 13224, as amended, for material support to Hamas. The individual carrying the title is Mahmoud al-Abyari, described by Treasury as a United Kingdom-based senior leader of the Egyptian Muslim Brotherhood and “Secretary General of the Muslim Brotherhood General Secretariat,” designated for having acted “for or on behalf of, directly or indirectly, the Egyptian Muslim Brotherhood.” Treasury says he supported fundraising for Filistin Vakfi and Hayat Yolu, two entities OFAC had previously sanctioned over Hamas ties. State Department spokesperson Thomas Pigott said the action “exposes the Muslim Brotherhood affiliates and Hamas-directed front organizations that use charitable facades and underground networks to disguise and move funds in support of terrorism.” State said all seven targets reside outside Egypt.

Britain has not proscribed the Muslim Brotherhood, and the 2014 government review of the organisation has never been reopened. The House of Lords debated the Brotherhood on 5 January 2026; Reform UK’s foreign policy plan, reported by The National on 7 February, named the movement a “terror group”; the New Statesman published a long read on the Brotherhood’s British networks in early July, before the designation. In the material The Files reviewed, no Foreign Office, Home Office or Office of Financial Sanctions Implementation response to the 23 July action had appeared by Sunday, and no public response from al-Abyari or from the Brotherhood itself. Two cautions travel with the name. The title is Treasury’s characterisation, not an independently verified organisational fact — the Brotherhood’s own account of its post-2021 leadership is contested. The transliteration varies: al-Abyari in Treasury’s text, Al-Ebiary and Al-Abyari in secondary pickup.

Assessment: OFSI mirroring is a choice, not a consequence, and the choice is political before it is legal. Washington has handed London a document asserting that the Brotherhood’s most senior claimed office-holder banks in Britain; every day Whitehall does not answer is a day the answer is supplied by others. Watch for the transmission mechanism rather than the statement: US designations function best as evidentiary scaffolding inside European administrative proceedings, which is how a Treasury press release becomes a French préfecture order or a British charity investigation. And treat the count of seven as a jurisdictional fact, not a scale of one. Four OFAC actions since January is the trendline; the number of names in each is not.
