Sanctioned nations moved $100B in crypto in 2025, an eightfold surge

Cryptocurrency addresses linked to U.S.-sanctioned entities — including Iran, Russia, and North Korea — received more than $100 billion in 2025, roughly an eightfold increase from the prior year, according to data from blockchain analytics firm Chainalysis reported by The Wall Street Journal on July 4.wsj+1

The finding, drawn from Chainalysis's 2026 Crypto Crime Report, underscores how sanctioned states have moved beyond experimental use of digital assets and now treat cryptocurrency as core financial infrastructure for circumventing Western restrictions.blockhead+1

How Sanctioned States Use Crypto

Iran's Islamic Revolutionary Guard Corps has received oil-sale payments routed through crypto exchanges, while Russia has used digital assets for international trade payments and to compensate sailors involved in smuggling sanctioned oil, The Wall Street Journal reported. North Korea, which has become adept at stealing cryptocurrency through state-sponsored hacking, has used the proceeds to purchase fuel and military equipment.bloomingbit+1

The nations are also building out their own crypto infrastructure. Russia legalized cryptocurrency payments in foreign trade effective July 1, 2026, giving exporters a formal path to accept Bitcoin ↗ 0.74% and stablecoins from buyers cut off from Western banking. Iran operated exchanges handling billions in volume, and North Korea relied on a ruble-linked token called "A7A5" alongside stolen funds.beincrypto+1

U.S. and Western Enforcement Response

Washington has escalated its countermeasures. On June 2, the Treasury Department's Office of Foreign Assets Control sanctioned four of Iran's largest cryptocurrency exchanges — Nobitex, Wallex, Bitpin, and Ramzinex — accusing them of facilitating sanctions evasion and terrorist financing. Nobitex alone handled more than 50 percent of Iran's digital asset inflows in 2025, according to the Treasury.chainalysis+2

Treasury Secretary Scott Bessent announced in late May that the U.S. had seized approximately $1 billion in Iranian cryptocurrency assets as part of the Trump administration's economic pressure campaign against Tehran. The European Union has also acted, banning 11 crypto platforms in its 21st sanctions package targeting Russia in June.timesofisrael+2

The Enforcement Gap

Despite stepped-up action, analysts say full enforcement remains elusive. Differing regulatory standards across countries allow sanctioned actors to route transactions through jurisdictions with weaker oversight. Total illicit crypto transaction volume reached $154 billion in 2025, with sanctions evasion accounting for the dominant share, according to Chainalysis.linkedin+2

"It is difficult to block all such activity because regulatory standards differ across countries," the Chainalysis report noted, a reality that has turned cryptocurrency into what one study called a "$350 billion shadow war" waged by hostile states over two decades.bloomingbit+1
