In April and May 2025, the Central Bank of Iran (CBI) secretly conducted two transactions using United Arab Emirates dirhams, acquiring over $500 million worth of Tether stablecoins (USDT). These transactions were not isolated incidents, but part of a systematic strategy.
According to a research report published by blockchain analytics firm Elliptic in January 2026, the Central Bank of Iran accumulated at least $507 million in USDT throughout 2025 via a network of wallets under its control. This "lower bound" figure reveals the scale of a massive digital asset reserve initiative.
Crisis Response: The Central Bank’s Digital Escape Amidst the Rial’s Collapse
Iran’s economic turmoil is the core driver behind its central bank’s pivot to cryptocurrencies. The Iranian rial has suffered catastrophic devaluation, losing half its value in just eight months and rendering its purchasing power nearly worthless.
As of January 2026, the rial’s exchange rate against the US dollar had plummeted to a staggering historic low of around 1:1,500,000. For comparison, when Iran signed the nuclear deal in 2015, the exchange rate stood at roughly 1:32,000. Domestic inflation has remained above 40% for an extended period, with food prices up 72% year-over-year and medical costs soaring by 50%. According to World Bank data, as much as 40% of Iran’s population now lives below the poverty line.
At the same time, international sanctions have cut Iran off from the global financial system. Oil exports are restricted, export revenues cannot be repatriated, and exclusion from the SWIFT network has severely undermined the central bank’s ability to defend its currency and control inflation.
Strategic Shift: From Centralized Exchanges to Cross-Chain Bridges
The Central Bank of Iran’s strategy for using USDT has evolved significantly in response to external events.
Initially, most of the central bank’s USDT flowed to Nobitex, Iran’s largest domestic cryptocurrency exchange, which processes about 87% of the country’s crypto trading volume. Through Nobitex, USDT functioned as a "parallel dollar reserve," allowing the central bank to exchange it for rials to support the local currency. However, on June 18, 2025, an unexpected hack changed the game. The pro-Israeli hacker group "Gonjeshke Darande" attacked Nobitex, stealing and destroying approximately $90 million worth of cryptocurrency. The group claimed Nobitex was a key tool for the Iranian regime to evade sanctions.
After this security incident, the central bank fundamentally altered its flow of funds. Rather than sending funds directly to Nobitex, it began moving assets from the TRON network to Ethereum via cross-chain bridges, then dispersing them through decentralized exchanges (DEXs) and other blockchains. This shift aimed to increase the stealth and censorship resistance of its fund transfers.
This strategic pivot underscores the critical need for platform security, censorship resistance, and autonomous asset control in complex environments. These are precisely the foundational pillars on which Gate, as a global leader in cryptocurrency exchanges, is built. Gate not only offers secure, compliant, and highly liquid centralized trading services, but also empowers users with seamless, one-stop cross-chain asset mobility and self-custody through deeply integrated cross-chain bridge technology and a robust DeFi ecosystem. This enables users to enjoy mainstream market convenience while maintaining full control over their assets—an essential capability for navigating rapidly changing market dynamics.
Compliance Counterattack: Tether Freezes and Market Impact
The Central Bank of Iran’s operations have not gone unchallenged. As a centrally issued stablecoin, USDT is always subject to control by its issuer, Tether. In response to potential violations of international sanctions, Tether has taken aggressive action. Since June 2025, Tether began systematically freezing wallets linked to Iran. The largest single action occurred on July 2, 2025, when 42 wallets associated with Iranian entities were blacklisted in one sweep.
By late June 2025, Tether had frozen a total of 112 wallets, involving about $700 million in USDT, with more than half linked to Nobitex or the Islamic Revolutionary Guard Corps (IRGC). These freezes had an immediate impact on Iran’s crypto market.
Between January and July 2025, Iran’s cryptocurrency trading volume fell 11% compared to the same period in 2024. In June alone, trading volume plummeted 50% year-over-year, and in July, it dropped another 76%. Many Iranian users were forced to swap TRON-based USDT for other stablecoins (such as DAI) or move their funds to overseas platforms.
Data Insights: USDT’s Real Price and Market Role in Iran
Against the backdrop of macroeconomic and geopolitical turmoil, how does USDT actually perform in Iran’s local markets? The following table, combining Gate platform market data with public information, reveals its critical value as a "digital dollar."
| Dimension | Data/Performance | Description & Source |
|---|---|---|
| Official Peg | 1 USDT ≈ $1.00 USD | Globally recognized fixed peg. |
| Local Fiat Exchange Rate | 1 USDT ≈ ﷼42,000.36 IRR (Gate data) | As per Gate platform’s latest rate on January 22, 2026. |
| Rial Black Market Rate | 1 USD ≈ ﷼1,500,000 IRR (market info) | Reflects the reality of extreme rial devaluation. |
| Implied Dollar Premium | 1 USD via USDT ≈ 35.7x official rate | Calculated as (1,500,000 / 42,000.36) ≈ 35.7. Highlights the scarcity value. |
| Market Roles | Store of value, cross-border payments, trade settlement | Used by the public for hedging, and by businesses/individuals for international trade and receiving overseas salaries. |
This comparison makes it clear that, amid the rial’s rapid devaluation, USDT provides local users with an "escape hatch" closely tied to the value of the US dollar. Despite the risk of regulatory freezes, its liquidity and broad acceptance make it an irreplaceable asset in crisis economies.
Double Bind: Stablecoins as Financial Tools and Sanctions Evasion
The case of Iran’s central bank highlights the complex and often contradictory role of stablecoins—especially centralized ones like USDT—in the global financial system.
For ordinary Iranians, USDT is one of the few realistic options to hedge against hyperinflation and preserve savings. Analysis shows that illicit activity accounts for only 0.9% of Iran’s crypto transactions, on par with the global average, indicating that most users are simply seeking to protect their wealth.
However, for sanctioned state entities such as the Central Bank of Iran and the IRGC, stablecoins serve as a parallel financial infrastructure for sanctions evasion. Elliptic describes the central bank’s USDT reserves as a "digital off-the-books Eurodollar account," enabling operations outside the reach of US financial oversight.
This dual-use nature puts stablecoin issuers in a compliance quandary. Tether must strike a difficult balance between meeting global regulatory demands (such as asset freezes) and serving populations excluded from traditional finance.
Global Impact: New Financial Games Under Blockchain Transparency
The Central Bank of Iran’s actions signal a new phase in state-level adoption of cryptocurrencies. This is not just financial innovation—it’s an extension of geopolitical competition into the digital realm.
Blockchain’s transparency and traceability are a double-edged sword. On one hand, they allow sanctioned entities to bypass traditional banks; on the other, every transaction leaves a permanent record, providing a trail for blockchain analytics firms like Elliptic. This has sparked a "sanctions technology race." Traditional banking sanctions push countries like Iran toward crypto assets, while blockchain analytics companies and stablecoin issuers develop increasingly sophisticated tools to track and block suspicious activity.
Global regulatory frameworks are responding rapidly. From the US and EU to Singapore, major economies are rolling out stablecoin compliance regimes requiring transparent reserve attestations, asset disclosures, and cooperation with law enforcement. In the future, the "regulability" of stablecoins may determine their mainstream acceptance—and pose their greatest challenge.
In the face of domestic monetary collapse, the Central Bank of Iran’s choices are just one example of a global trend. In Caracas, Buenos Aires, and Ankara, people are making similar decisions: exchanging their rapidly depreciating local currencies for digital vouchers worth one US dollar in a mobile wallet. According to Gate platform data, one USDT can currently be exchanged for 42,000.36 Iranian rials. Yet on the streets of Tehran, it takes many times that amount in rial banknotes to obtain a single physical dollar. This price gap measures not just the credibility deficit of a national economy, but also the financial reality faced by hundreds of millions of ordinary people around the world.
