The UK government has today imposed an immediate moratorium on all political donations made in cryptocurrency, a move designed to slam the door on a significant avenue for illicit foreign finance identified by a major security review.
Announcing the measure in the House of Commons, the Secretary of State for Housing, Communities and Local Government, Steve Reed, confirmed he was accepting a key recommendation from the Rycroft Review. That report, led by former senior civil servant Philip Rycroft and published today, concluded there was “a risk crypto assets are used as a vehicle to channel foreign money into the political system in the UK”.
The Crypto Crackdown: Anonymity and Unacceptable Risk
The heart of the concern, as set out by Mr Rycroft and adopted by ministers, is the fundamental anonymity of cryptocurrency transactions. Steve Reed told MPs that this anonymity “could make it easier to mask the origin of donations and to evade robust checks on the true source of funds.” This creates, he said, “a clear route… for illicit channelling of money into our politics” which “undermines public confidence in our electoral system.”
The issue had been highlighted as an “unacceptably high risk” by the cross-party Joint Committee on the National Security Strategy (JCNSS), which has long called for such a ban. Specific risks cited in the review include the potential for foreign states to influence UK politics, and technical methods to obscure money flows, such as using crypto “mixers”, hopping between different currencies, or exploiting privacy-focused coins.
Furthermore, the government is targeting the risk of evasion through volume, applying the ban to crypto donations “in any amount.” This closes a potential loophole where multiple small donations, each below the existing disclosure threshold, could be rapidly funnelled into a party’s coffers without detection.
The moratorium will remain in force indefinitely, Mr Reed said, “until the Electoral Commission and this parliament are satisfied there is sufficient regulation in place to ensure full confidence and transparency in donations being made in this way.” While some in the cryptocurrency industry have argued for regulation over an outright ban, the government has sided with security concerns in taking this preventative step.
Cap Imposed on Donations from British Voters Abroad
In a parallel move also taking effect immediately, the government is imposing a strict annual cap of £100,000 on donations from British citizens living overseas. This, too, follows a direct recommendation from the Rycroft Review, which suggested a cap in the range of £100,000 to £300,000 per donor per year.
The review identified two core problems with the existing system for overseas electors, whose right to donate was expanded by the Elections Act 2022. First, it noted that “inevitably tracing the source of funds offered by individuals living abroad is more complex than for domestic donations.” Second, it raised a question of “democratic fairness,” whereby individuals who live abroad and are taxed elsewhere can nonetheless make “potentially game changing donations” into British politics.
“In light of the gravity of the issues raised in the report, I am not prepared to allow any window of opportunity in which malign actors based overseas can funnel dark money into our politics,” Steve Reed told MPs. The cap will apply to all UK elections, including the upcoming local and devolved contests, and the government intends to seek legislative consent motions from the Scottish and Welsh governments to ensure uniform safeguards across the union.
The new regulations are expected to have a pronounced impact on Reform UK. The party has received approximately £12 million in the last year from a single overseas donor, the Thai-based British investor Christopher Harborne, a shareholder in the cryptocurrency firm Tether. It has also received other donations from individuals based in Monaco. The £100,000 annual cap will severely restrict the scale of such financial support.
Retrospective Application and Enforcement
Both the cryptocurrency moratorium and the overseas donor cap are being applied retrospectively from today, 25 March 2026. The legal authority for this will come via an amendment to the broader Representation of the People Bill, which is currently before Parliament.
Once the provisions formally come into force, any political party or regulated entity that has received a prohibited cryptocurrency donation or an overseas donation exceeding the £100,000 cap since today will have 30 days to return the funds. After that window closes, enforcement action can be taken and criminal penalties will apply.
These sweeping changes mark the most significant tightening of political finance rules in years, directly responding to warnings from security experts about the vulnerability of the UK’s democratic processes to foreign financial influence. The moves implement the core proposals of the Rycroft Review, which was commissioned in December 2025 specifically to examine the effectiveness of safeguards against illicit foreign money in UK politics.
