Israel Uses Crypto to Weaponize Finance Against Iran

Israel Seizes $1.5B in Tether Allegedly Linked to Iran

In a significant move targeting financial transactions with Iran, Israel has reportedly seized $1.5 billion in Tether (USDT), a widely used stablecoin pegged to the U.S. dollar. The assets were allegedly linked to Iranian financial entities and were frozen following intelligence and enforcement actions by Israeli authorities. This operation marks one of the largest single seizures of cryptocurrency in Israel’s history and underscores its increasing focus on monitoring and curbing digital assets tied to adversarial nations.

Tether, a major stablecoin issuer, has been under global scrutiny for its reserves and transparency, yet its role in facilitating cross-border transactions, particularly those circumventing traditional banking systems, has raised concerns among policymakers and regulators. While the company has not publicly commented on the seizure, its operations are known to involve complex financial arrangements, including gold and treasury holdings, as reported by various industry analysts. The Israeli government has not disclosed whether it will attempt to repatriate the funds, but such actions are often used to send a message of deterrence to state-backed actors.

The move comes amid heightened tensions between Israel and Iran, with both nations engaging in indirect confrontations through proxies and cyber operations. Iran, a key backer of militant groups in the region, has long been accused of exploiting cryptocurrency to evade international sanctions. The seizure of Tether assets highlights how digital currencies can become a tool for geopolitical leverage. According to the Times of Israel, Israeli officials have increasingly focused on disrupting Iran’s financial networks, especially as traditional channels are more tightly monitored.

The legal and operational framework for such actions remains unclear. In Israel, where the financial sector is highly regulated and national security concerns often take precedence, the government has broad powers to freeze assets suspected of being connected to hostile actors. The central bank and enforcement agencies have been granted extensive authority to act on intelligence reports, particularly in cases involving national security. This has led to speculation about the broader implications for financial privacy and the use of digital assets in international conflicts.

While the seizure may not immediately alter the geopolitical landscape, it signals Israel’s readiness to use financial tools as part of its strategic toolkit. Analysts note that such actions can have a chilling effect on the use of stablecoins for illicit purposes, as jurisdictions increasingly collaborate to track and disrupt suspicious transactions. However, the lack of transparency in the operations of stablecoin issuers like Tether complicates enforcement efforts and raises questions about the enforceability of such actions in the long term.

The global stablecoin market, valued at over $4 trillion in 2025, continues to expand despite regulatory headwinds. Governments and international organizations are working to establish clearer frameworks for oversight, particularly in response to the risks posed by unregulated or opaque stablecoin ecosystems. In the U.S., for example, the passage of the GENIUS and CLARITY acts in July 2025 signals a shift toward formalizing the legal and regulatory status of stablecoins. Similar efforts are expected to gain traction elsewhere as the use of digital assets becomes more mainstream.

Israel’s actions against Tether-linked assets reflect a broader trend of nations treating cryptocurrency as a critical battleground in geopolitical and economic conflicts. As digital currencies continue to evolve, their role in national security and economic strategy is likely to expand, prompting further regulatory and legal developments worldwide.
