Several major cryptocurrency exchanges warned users this week that transfers involving $HTX could face additional compliance checks after the United Kingdom sanctioned the exchange over alleged ties to Russian financial networks.
The U.K. government added $HTX to its Russia sanctions list as part of a broader package targeting entities accused of helping sanctions evasion and illicit financial activity linked to Moscow.
British authorities said they had “reasonable grounds to suspect” $HTX provided financial services connected to sanctioned entities including crypto exchange Garantex and the A7 network, whose A7 LLC issues the ruble-pegged A7A5 stablecoin.
The Foreign Office said the A7 network had used a Kyrgyz bank and a major cryptocurrency exchange to channel an estimated $1.5 billion back into Russia. The A7 network claimed to have moved more than $90 billion last year, the Foreign Office said, roughly half of Russia’s annual military expenditure.
The designation carries immediate practical consequences. U.K. financial institutions are now barred from doing business with the exchange and may face penalties for interacting with crypto transactions that pass through it.
U.K.-registered virtual asset service providers are legally required to freeze funds connected to the designated entities, blockchain analytics firm Elliptic said, and the sanctions extend to restrictions on correspondent banking relationships and payments involving $HTX.
Following the announcement, exchanges including Binance, OKX, Bybit and Bitget issued notices warning users about heightened scrutiny tied to $HTX-related transactions.
Bitget said it updated its sanctions screening systems and warned that transactions involving sanctioned entities or linked addresses could face rejection, restrictions or account termination.
Binance, meanwhile, said transactions involving $HTX “may be subject to additional compliance review” as part of its sanctions controls.
OKX separately warned users who previously engaged in arbitrage trading between $HTX and OKX that continued transfers between the platforms after the sanctions action could trigger additional scrutiny on their accounts.
Bybit also cautioned that deposits or withdrawals involving $HTX-linked addresses may face added anti-money laundering and risk-control checks.
“Users are advised to avoid using $HTX-related addresses when interacting with Bybit and to ensure that all account activities remain compliant with local laws and platform policies,” Bybit wrote.
$HTX rejected the U.K.’s claims it helped Russia’s financial infrastructure, even saying it has refused a listing application for the A7A5 stablecoin.
“To clarify, the listed entity Huobi Global S. A. is distinct from the online $HTX exchange,” the company said. “While Huobi Global S.A. will work with relevant UK authorities to understand the basis for the action and to address any concerns promptly, the designation does not and should not have any impact on the online $HTX exchange.”
