The UK government is facing a pivotal decision on how to strengthen enforcement against illicit finance, particularly in relation to overseas territories, crown dependencies, and the professionals who facilitate money laundering and fraud. Despite increasing national security concerns, there has been a historical reluctance among successive administrations to apply robust measures, though precedent exists for the government to assert authority—such as the 2000 decision to legalize homosexuality in five Caribbean territories.

Legal experts argue that the government has the power to impose mandatory transparency through orders in council, especially concerning the identification of beneficial owners of companies registered in overseas territories and dependencies. Yet, the key challenge remains whether political will exists to take such action. Critics emphasize that these jurisdictions continue to represent significant vulnerabilities within the global financial system. Transparency International reports that since Russia’s 2022 invasion of Ukraine, offshore entities in UK-linked territories like Bermuda and the British Virgin Islands facilitated roughly £6 billion in trade with Russia, including transactions involving at least 160 yachts.

A major area of concern is the incomplete and poorly enforced register of overseas entities, which requires companies—but not trusts—to disclose beneficial ownership of property. Current enforcement is weak: only an estimated 3% of fines for non-compliance have been collected. Draft regulations published in April aim to enhance transparency by allowing public access to trusts’ beneficial ownership information. Campaigners argue these measures need to be more comprehensive.

Enforcement efforts overall remain limited. While the UK can freeze assets of sanctioned individuals, such as Russian oligarchs, it lacks authority to seize properties and has yet to recover real estate from those linked to Vladimir Putin’s network. Only one bank, NatWest, has faced a significant penalty under money-laundering laws, and total criminal asset recoveries in 2022-23 amounted to £339 million—minuscule compared with the estimated billions lost annually to illicit finance in the UK. The convictions of professionals involved in money laundering are rare, exemplified by the 2023 sentencing of London solicitor William Osmond, whose firm handled £388 million for a single client over 16 years.

The government has pledged to establish a single anti-money-laundering supervisor, consolidating oversight of 22 professional bodies under the Financial Conduct Authority. This reform, legislated under the forthcoming financial services bill, aims to enhance accountability but may take years to fully implement.

In the cryptocurrency sector, the UK has shown more decisive action. Companies House recently moved to strike off a UK-registered exchange accused of facilitating $1 billion in transactions for Iran’s Revolutionary Guards. In May, the Treasury sanctioned several Russian-linked crypto platforms, applying correspondent-banking restrictions for the first time. The November jailing of "crypto queen" Qian Zhimin marked the seizure of over 60,000 bitcoin—worth more than £5 billion at the time—the largest such law enforcement recovery in British history.

Conversely, regulation of illicit gold trading remains underdeveloped despite concerns that gold is financing conflicts in Ukraine and Sudan. With the UK hosting the world’s largest bullion market, campaigners warn current government ambition falls short in addressing the estimated $30 billion global illicit trade.

Officials caution that probing illicit finance could face setbacks if it comes into conflict with efforts to promote economic growth. Some ministers have considered reinstating golden visas, a move criticized by anti-corruption groups as potentially inviting kleptocrats and criminals. Past parliamentary inquiries highlighted Britain’s “light touch” financial regulations as factors enabling London’s role as a laundering hub.

As the UK prepares to host a major summit in December coinciding with its G20 presidency, there is an opportunity to forge a “coalition of the willing” involving EU states, Canada, Australia, Indonesia, and South Korea, among others, to set higher global standards independent of US leadership. Observers warn, however, that a lack of sustained governmental focus could undermine progress on curbing illicit finance, which remains a significant challenge to national security and financial integrity.
