Iran’s once booming crypto market is now facing a major blow. In 2025, digital asset trading in the country collapsed amid geopolitical tensions, Tether freezes, and the operational breakdown of Nobitex, Iran’s largest crypto exchange.

Iranian Crypto Flows Drop Sharply

According to blockchain analytics firm TRM Labs, total crypto inflows into Iran from January to July 2025 reached only $3.7 billion. This figure was down 11% compared to 2024.

But things got much worse after April:

• June 2025: crypto inflows dropped more than 50% year-on-year.
• July 2025: the decline deepened to 76%, signaling a major shock to the domestic market.

Hacks, War, and Frozen Wallets

Several key factors rattled Iran’s crypto market, including:

• Geopolitical conflict – the collapse of nuclear talks with Israel and the outbreak of armed conflict in June.
• Nobitex hack – losses of up to $90 million from an attack by the Predatory Sparrow group, which exploited exchange security flaws.
• Tether wallet freezes – 42 addresses linked to Iran were frozen, many belonging to Nobitex and actors affiliated with the IRGC (Iranian Revolutionary Guard Corps).

The impact? Liquidity froze, transactions slowed, and users fled to foreign exchanges or alternative stablecoins like DAI on Polygon.

Nobitex: Dominant but Vulnerable

Despite the turmoil, Nobitex still controlled 87% of Iran’s crypto trading volume in 2025, processing over $3 billion. About $2 billion of that moved through the Tron network, mainly using TRC-20 USDT and TRX.

This dominance brings efficiency but also systemic risk. When Nobitex was paralyzed by the hack, the entire Iranian crypto ecosystem was shaken.

New Regulations: Iran’s Crypto Tax

In addition to external factors, domestic regulation added pressure. In August 2025, the Iranian government enacted the Speculation and Profit Registration Tax Law.

Now, crypto trading is subject to capital gains tax, just like gold, real estate, and foreign currency. Although full enforcement is still being phased in, the policy signals Tehran’s attempt to formally regulate and control digital assets.

Crypto Still a Strategic Weapon for Iran

Even with a weakened domestic market, crypto remains crucial for Iran, particularly to bypass international sanctions. Examples include:

• Buying drone components and AI equipment from Chinese suppliers using crypto.
• Underground KYC networks providing fake identities to register on global exchanges.

This means that while retail investors are hit hard, the Iranian regime continues to leverage crypto for strategic operations.

Conclusion

Iran’s crypto market in 2025 faces a perfect storm: inflows have plunged more than 76%, its main exchange was hacked, wallets were frozen, and new tax rules came into force.

But beneath the turbulence, the picture is clear:

• Crypto remains a strategic tool for the regime to evade sanctions.
• Systemic risk is high due to dependence on Nobitex and USDT.
• Domestic investors are under pressure from geopolitics and regulation.

For the global crypto world, Iran’s story is a reminder that digital assets are not just financial instruments, but also geopolitical weapons.
