Britain sanctions five crypto platforms a week after Washington blacklisted Russia's A7 network

A7's volume claim and FinCEN's finding measure different things. The Foreign Office said A7 claimed to have moved more than $90 billion during 2025, and it presented that as the network's own figure ^[5]. According to FinCEN, agents tied to the network handled more than $17 billion in dollar transactions from January 2025 through June 2026 ^[15]. Spread over those 18 months, that comes to about $11.3 billion a year ^[16], roughly an eighth of what A7 says it moves ^[17]. If both numbers hold, most of A7's claimed volume did not pass through the dollar agents FinCEN traced. Britain says two of the platforms it named on Oct. 8 processed or facilitated A7 transactions ^[2]. A simpler reading also fits. A network that sells sanctions evasion has a reason to round its volume up, and the $90 billion may be a sales pitch.

Within about three months, all three Western regimes have moved against crypto payment channels. The EU's July package extended transaction bans to 14 crypto-related platforms across six jurisdictions ^[13]. On Oct. 1, under what Treasury calls Operation Economic Outcast, OFAC designated A7 as a transnational criminal organization and FinCEN proposed restrictions on transfers involving its overseas payment agents ^[9]. Britain's turn came on Oct. 8, and crypto made up six of the 38 names in its package, about one in six ^[18]. Kyrgyzstan keeps coming up. The Foreign Office said three of the new targets had links to the country ^[4], and Britain's May 26 round had already hit Russia-linked crypto and financial businesses registered there, in the UAE and in Georgia ^[8].

For counterparty screening, each regime reaches further than its list. OFSI's guidance explicitly counts cryptoassets among the assets a freeze covers ^[6]. It binds UK nationals and British-incorporated companies wherever they operate, and it can extend to companies a designated person owns or controls ^[7]. Treasury's version blocks A7 property in the US or held by US persons, plus any entity owned 50% or more by blocked persons ^[10]. One of the UK's designated companies is Xeltox Enterprises, which the crypto.news report links to the crypto services Cryptomus and Heleket ^[3]. A compliance team matching counterparties by the name on the app has to trace those two brands back to Xeltox before its screen catches anything.

The US measure aimed most directly at crypto flows is still a draft. FinCEN's transfer restriction is a proposal, and comments close 30 days after the notice appears in the Federal Register ^[11]. As proposed it covers conventional funds and convertible virtual currency alike ^[12]. FinCEN's accompanying alert, as crypto.news reported it, points institutions to suspicious trade records, unexplained high-volume transactions and payment routes running through several countries ^[14]. Until the rule is final, US persons are bound by the OFAC block, and the transfer ban is only a proposal ^[10][11].

From here it can go three ways. If FinCEN finalises the rule with crypto coverage intact, a US transfer ban, a UK freeze and EU platform bans will all apply to the same rails at the same time. If it narrows the final rule to conventional funds, crypto stays under designations alone. Separately, the services could resurface under new legal entities, and the owned-or-controlled and 50% tests catch those only when the ownership is visible. I'd expect the first outcome, because the proposal and the alert both name crypto explicitly ^[12][14]. A final rule that drops convertible virtual currency would prove that expectation wrong.
