Japan Sanctions Garantex, 33 Entities Over Russia’s War

Japan’s government added Russian cryptocurrency exchange Garantex to an expanded sanctions list on Oct. 2, 2026, folding the platform into a package that also freezes the assets of 33 entities and nine individuals and restricts 35 vessels tied to Russia’s oil trade. The measures were issued under the Foreign Exchange and Foreign Trade Act following a Cabinet decision, Cointelegraph reported.

The joint statement came from Japan’s Ministry of Foreign Affairs, Ministry of Finance and Ministry of Economy, Trade and Industry. Garantex had already faced sanctions from the United States, the European Union and other jurisdictions for helping Russian entities evade financial restrictions.

What Japan’s sanctions actually change

The package reaches beyond the exchange itself. Japan applied the same permission requirement to capital transactions involving deposits, trusts and money loans with designated parties, and introduced export prohibitions covering four entities outside Russia and Belarus, alongside further restrictions on goods that could feed Russia’s industrial capacity.

One limitation stands out. The government describes the measures as an asset freeze, but the notice does not disclose the value of any Garantex-linked assets located in Japan, and it does not identify cryptocurrency wallets connected to the exchange or state that a particular amount of digital assets was frozen, crypto.news reported. Garantex is the only cryptocurrency exchange named in the appendix among the latest Russian entities.

Japan has also not announced a separate grace period for Garantex-related transactions in its English-language notice, crypto.news noted. The transitional relief attached to vessel contracts runs only until Nov. 1, 2026.

The years of enforcement that preceded Tokyo’s move

Garantex’s troubles predate Japan’s designation by several years. The U.S. Treasury’s Office of Foreign Assets Control first sanctioned the exchange in April 2022, saying its analysis linked more than $100 million in known Garantex transactions to illicit actors and darknet markets, including funds associated with the Conti ransomware group and the Hydra marketplace.

OFAC re-designated Garantex in August 2025 under U.S. cyber sanctions authorities, repeating the estimate that more than $100 million in transactions since 2019 were connected to illicit activity and stating the exchange had “directly facilitated” ransomware actors and other cybercriminals. The European Union had placed Garantex under sanctions in February 2025, describing it as a Russia-based cryptocurrency exchange closely associated with EU-sanctioned Russian banks.

Law-enforcement action followed weeks later. U.S. authorities seized three domains used by the exchange on March 6, 2025, while German and Finnish authorities seized servers supporting its operations. Garantex suspended services after Tether froze more than 2.5 billion rubles worth of USDT connected to the exchange. U.S. prosecutors subsequently unsealed charges against Garantex administrators Aleksej Besciokov and Aleksandr Mira Serda; the Justice Department alleged the exchange facilitated money laundering and sanctions violations and said it processed at least $96 billion in cryptocurrency transactions since April 2019. Those criminal accusations remain allegations.

U.S. authorities later targeted Grinex, describing it in Treasury’s August 2025 sanctions notice as a successor created by Garantex employees to keep providing services after the disruption. OFAC said customer deposits were transferred to the new platform and that Grinex later processed billions of dollars in cryptocurrency transactions. Treasury also said Garantex customers regained access to some balances through A7A5, a ruble-backed digital asset issued by Old Vector, a company whose parent A7 network was accused of supporting sanctions-evasion activity.

Why it matters

Japan’s designation widens the circle of jurisdictions treating Garantex as a sanctions-evasion channel, which raises the cost for any exchange, payment processor or bank that still touches the platform or its successor networks. For traders and businesses with Russian counterparties, the practical shift is procedural: payments and capital transactions involving listed parties now need government permission rather than falling under prior exemptions.

The measure also underscores a recurring problem in crypto enforcement. Blockchain intelligence firm TRM Labs previously said that entities like Garantex “appear to prepare contingency plans well in advance of anticipated enforcement measures,” allowing them to migrate clients, infrastructure and funds to successor platforms — the pattern U.S. authorities say played out with Grinex and the A7 network.

What to watch

The tightest near-term deadline is Nov. 1, 2026, when limited relief for pre-Oct. 2 vessel contracts expires. Beyond that, the FinCEN proposal targeting A7 sub-agents — an investigation that found more than $17 billion processed between January 2025 and June 2026 — will show whether Washington and Tokyo can close the migration route that Garantex’s operators have relied on.
