Sanctions Target Crypto Exchange and Vessels

On October 2, 2026, Japan announced expanded restrictions against Russia under its Foreign Exchange and Foreign Trade Act. The measures add 33 organizations and nine individuals to an asset-freeze list, with Garantex listed as the sole cryptocurrency exchange among them. Payments and specified capital transactions involving the designated parties now require explicit government permission.

The package also covers 35 vessels identified as part of Russia's shadow fleet, which transports oil while evading existing sanctions. Services such as repairs and insurance for these ships, along with related money loans and debt guarantees, face additional controls. Japanese authorities said the steps aim to limit Russia's ability to generate revenue from crude oil exports.

Details of Garantex Designation

Garantex appears in the official appendix under its formal name, Garantex Europe OU, with the common alias also noted. Addresses listed include those in St. Petersburg and Moscow, including the Federation East Tower. The sanctions apply to payments and capital transactions such as deposits, trusts, and money loans connected with the exchange.

No specific value of assets tied to Garantex was disclosed in Japan's notice, nor were any cryptocurrency wallets or digital assets identified as frozen. The restrictions took effect immediately with the October 2 announcement and extend to any services or financing provided after that date.

Vessel Restrictions and Transitional Provisions

Obligations based on contracts signed before October 2 may continue only if performed before November 1, 2026, providing a narrow window for existing arrangements. This applies specifically to the 35 vessels and their associated services.

Background on Prior Actions

Garantex has faced repeated scrutiny in other jurisdictions for its role in facilitating sanctions evasion. The U.S. Treasury sanctioned the exchange in April 2022 after linking more than $100 million in transactions to illicit actors and darknet markets. A second designation came in August 2025 under cyber authorities, with the same transaction volume cited.

The European Union added Garantex in February 2025 as part of its 16th sanctions package against Russia. Authorities described it as a platform closely associated with sanctioned Russian banks. Law-enforcement actions followed, including domain seizures in the U.S., server seizures in Germany and Finland, and the freezing of more than 2.5 billion rubles worth of USDT by Tether.

The joint statement from Japan's Ministry of Foreign Affairs, Ministry of Finance, and Ministry of Economy, Trade and Industry framed the new package as consistent with ongoing efforts to address the war in Ukraine. No separate grace period was announced for Garantex in the English-language notice, unlike the temporary relief provided for pre-October 2 vessel contracts.

Garantex's Evolution and Related Platforms

Following earlier disruptions, Garantex customers and funds reportedly shifted to a successor platform called Grinex. U.S. authorities later sanctioned that entity as well. Some balances moved to a ruble-backed digital asset called A7A5 issued by Old Vector. A day before Japan's announcement, the U.S. Treasury designated the A7 Network as a transnational criminal organization, citing sub-agents that processed more than $17 billion in transfers between January 2025 and June 2026.

Blockchain intelligence reports have noted that Garantex maintained contingency arrangements in advance of enforcement, allowing potential migration of operations to new structures. Japan’s designation builds on these patterns by targeting a key node in the ecosystem.

Broader Context of the Sanctions Package

Japan’s action aligns with a wider international approach that combines financial controls with measures against logistics and trade enablers. The vessel restrictions seek to disrupt the operational capacity of the shadow fleet, while the designation of Garantex addresses its function in channeling value for Russian entities.

The measures follow a Cabinet decision and were issued under the Foreign Exchange and Foreign Trade Act. They form part of Japan's commitment to support international sanctions against Russia's aggression in Ukraine.
