The United Kingdom on Tuesday slapped sanctions on the A7 network and several cryptocurrency exchanges, accusing them of helping to move $1.5 billion to support Russia's war effort. It marks the first time London has directly targeted crypto infrastructure for facilitation of military financing.
The A7 network and the exchanges
The A7 network is described by the UK government as a shadow financial system that channels money to Russian defense firms and intelligence agencies. The exchanges named in the sanctions order — the UK did not disclose their identities — are alleged to have processed transactions linked to the network. The sanctions freeze any assets they hold in UK jurisdiction and bar British citizens and companies from doing business with them.
How the funds moved
Authorities say the $1.5 billion flowed through a web of shell companies, crypto wallets, and exchange accounts. The UK Treasury's Office of Financial Sanctions Implementation (OFSI) traced payments that originated from Russian state-linked entities and ended up with suppliers of military equipment. Crypto was used to layer transactions and evade traditional banking oversight, according to the government's statement.
UK's expanding crypto sanctions toolkit
This isn't London's first crackdown on crypto-related sanctions evasion, but it's the most direct hit on exchanges themselves. Previous measures focused on individual wallets and designated Russian oligarchs. Tuesday's action signals that the UK is now willing to go after the platforms that enable the flows. The timing comes as Western allies intensify efforts to cut off Russia's war financing ahead of another winter of fighting.
What happens to the frozen assets
Any crypto or other assets held by the designated entities in the UK are now frozen. OFSI can grant licenses to unfreeze funds for humanitarian or legal costs, but otherwise the money is locked. The government said it will continue to monitor crypto-based sanctions evasion and may add more entities to the list. For now, the named exchanges face a practical problem: they can't operate in the UK, and any British-linked customers or partners have to unwind relationships immediately.
