Senator Elizabeth Warren has warned that U.S. adversaries are using cryptocurrency to move billions of dollars, framing digital assets as a growing national-security threat tied to sanctions evasion by Iran, North Korea, and Russia.
What to Know
- Warren said crypto finances threats including North Korea’s weapons program, Iranian sanctions evasion, and ransomware attacks on U.S. hospitals.
- The U.S. Treasury sanctioned Iranian exchange Nobitex in June 2026, saying it processed more than 50% of all Iranian digital-asset inflows.
- Chainalysis found that sanctioned entities received $104 billion in crypto in 2025, a 694% year-over-year surge.
What Warren Said About Crypto and U.S. Adversaries
At a May 2, 2024 Senate hearing, Warren called for applying strong anti-money-laundering protections to cryptocurrency to shut down financing for adversaries and terrorist groups. She cited North Korea, Iran, and Russia as countries exploiting crypto rails to circumvent U.S. sanctions.

Director of National Intelligence Avril Haines confirmed during that hearing that over 50% of North Korean foreign-currency revenues now come through crypto. Haines also confirmed that Iran uses cryptocurrency to move money across borders. For related coverage, see China Reinforces Crypto Ban, Targets Offshore Stablecoins.
Warren cited a Wall Street Journal report stating that crypto had become indispensable to Russia’s war effort, according to the report allowing Russia to circumvent sanctions and direct billions of dollars toward its war against Ukraine. The underlying Journal report was not independently verified for this article.
The senator’s warnings have only gained weight since. On June 2, 2026, the U.S. Treasury sanctioned the Iranian exchange Nobitex, saying it processed more than 50% of all Iranian digital-asset inflows in 2025 and helped the Central Bank of Iran access hundreds of millions of dollars in stablecoins.
Treasury Secretary Scott Bessent said the U.S. had seized about $1 billion of Iranian crypto, according to AP reporting on the sanctions announcement. The action targeted Nobitex alongside other Iranian exchanges including Wallex, Bitpin, and Ramzinex under Executive Orders 13224 and 13902.
Blockchain analytics firm Chainalysis reported that value received by sanctioned entities surged 694% in 2025 to $104 billion. IRGC-linked Iranian addresses alone moved over $3 billion in 2025, according to the same report.
Why the Claim Matters for Crypto Regulation and Enforcement
Warren’s framing links crypto policy directly to national security rather than financial innovation. That framing has historically been used to push for tighter compliance requirements on exchanges and stablecoin issuers, particularly around anti-money-laundering and Bank Secrecy Act obligations.
The Treasury’s Nobitex action demonstrates how enforcement agencies are now targeting specific crypto infrastructure used by sanctioned states. The sanctions used executive orders originally designed for counter-terrorism and Iran-specific non-proliferation, applying them to digital-asset platforms for the first time at this scale.
Warren has consistently argued that any legislation expanding or legitimizing crypto should close AML gaps first. She has criticized recent crypto clarity legislation on similar grounds, warning that loosening oversight before closing enforcement gaps invites abuse.
The Chainalysis data supports the scale argument. A 694% year-over-year increase in sanctioned-entity inflows moves the conversation from anecdotal examples to a systemic pattern, giving regulators and lawmakers quantitative backing for tighter controls.
Warren’s concern also extends to how private companies handle compliance. During the same hearing, she referenced a claim that Binance processed $8 billion in transactions for Iran over four years, though the underlying sourcing for that figure was not independently verified for this article.
What Crypto Investors and Firms Will Watch Next
The immediate pressure falls on exchanges and stablecoin issuers operating in jurisdictions with exposure to sanctioned entities. Treasury’s willingness to sanction Nobitex, which handled a majority of Iranian crypto inflows, signals that platforms enabling even indirect sanctions evasion face direct enforcement risk.
Warren has also challenged Meta’s reported stablecoin partnership plans, suggesting that scrutiny will extend beyond dedicated crypto exchanges to any large technology company building on digital-asset rails.
For U.S.-based firms, the political dynamic matters. When senior lawmakers frame crypto as a sanctions-evasion tool, compliance expectations tighten. The ongoing delays in Senate crypto legislation reflect the difficulty of advancing a regulatory framework while national-security concerns dominate the debate.
Cross-border stablecoin platforms face particular exposure. Treasury’s finding that the Central Bank of Iran used Nobitex to access hundreds of millions in stablecoins puts dollar-pegged tokens at the center of the enforcement discussion.
Readers tracking this story should monitor whether Treasury designates additional exchanges beyond the four named in the June 2026 action, and whether pending crypto legislation incorporates the AML provisions Warren has demanded as a precondition for any broader regulatory framework.
