Britain just gave itself a new legal weapon against foreign state threats, and Iran’s Islamic Revolutionary Guard Corps is the first major target. The National Security (State Threats) Act 2026 received royal assent on July 8, creating a proscription-style designation framework that treats state-linked organizations with the same legal severity typically reserved for terrorist groups.

On July 13, the UK government named its first batch of designated entities: the IRGC, the Islamic Movement of Companions of the Right (IMCR, also linked to Iranian activities), and Russia’s GRU Volunteer Corps. Anyone providing support or assistance to these organizations now faces up to 14 years in prison. Acts of sabotage, like arson, could mean life behind bars.

While the legislation itself doesn’t mention cryptocurrency or digital assets, the IRGC’s alleged use of digital currencies for sanctions evasion has been a recurring theme in reports throughout the first half of 2026. That makes this law relevant well beyond Westminster’s corridors, and squarely into the territory of crypto exchanges, compliance teams, and anyone moving value across borders.

Why existing laws weren’t enough

The UK’s previous counterterrorism framework had a glaring blind spot. It was built to handle non-state actors like militant groups, not sophisticated operations run by foreign governments. The legal toolkit designed to go after rogue organizations simply didn’t fit when the rogue organization was a branch of a sovereign nation’s military.

The IMCR alone has been linked to seven claimed attacks on UK Jewish or Israeli-linked sites in 2026. Independent reviewer Jonathan Hall KC conducted a review in 2025 that examined the scope of alleged Iranian operations within the UK. His findings confirmed that the existing legal architecture was inadequate. The new Act fills that void with tailored designations that can target state-linked entities specifically, rather than trying to shoehorn them into terrorism statutes that weren’t designed for the purpose.

The EU had already moved in this direction. It designated the IRGC as a terrorist organization on February 19, 2026, nearly five months before Britain’s legislation received royal assent. The UK’s approach creates an entirely new legal category rather than expanding existing terrorism definitions.

The crypto connection hiding in plain sight

Reports from January through June 2026 have documented the IRGC’s alleged use of digital currencies to circumvent international sanctions, routing transactions through various exchanges. The question for crypto market participants is straightforward but uncomfortable: what constitutes “support or assistance” in the context of a decentralized financial system? The Act’s broad language suggests that exchanges unknowingly processing transactions that ultimately benefit a designated entity could face legal exposure.

For exchanges operating in or serving UK customers, this creates a compliance imperative that goes beyond standard anti-money laundering protocols. The designation of three separate entities under the new law signals that this framework will be actively used.

What this means for crypto investors and exchanges

Any platform facilitating transactions that could be traced back to designated entities now operates under significantly elevated legal risk in the UK. For individual investors and traders, participating in exchanges or protocols that have exposure to sanctioned entities could create downstream problems, ranging from frozen accounts to outright legal jeopardy.

One gap worth watching: the Act creates the legal framework for designation but doesn’t explicitly address the technological challenges of tracking digital asset flows linked to state actors. If the IRGC has indeed been using crypto for sanctions evasion, as reports throughout 2026 suggest, then enforcement will need tools and authorities that may not yet exist in their current form.
