London is the leading global location for new regulatory technology start-ups, according to FinTech Global, a specialist data and intelligence finance firm.
The next six locations in the city rankings are based in North America.
Dublin and Paris are the only other European cities to appear in the top 10.
Over the last five years, investments in London-based companies have grown by a compound annual growth rate of 38.5 per cent with a record $678m (£544.75m) invested in 70 companies in 2016.
Among 2016's largest deals was the raising of $25m (£20m) in finance for Onfido, a global identity verification service, while adaptive behavioural analytics firm Featurespace raised $9m (£7.2m) and ComplyAdvantage raised $8.2m (£6.5m).
While these deals have been funded by private equity specialists, the majority of deals are funded by early-stage funding accelerators.
As such, three of the top 10 most active RegTech investors worldwide in terms of numbers of deals are based in London: Techstars, Wayra and StartupBootcamp have made 21 London-based RegTech investments between them, averaging $70,000 (£56,000) per investment.
A further trend in 2016 was the funding of anti-fraud companies overtaking the funding of compliance-focused companies, according to FinTech Global, with $334.8m (£269m) invested in anti-fraud companies in total.
The data for this research comes from the Fintech Global database, which provides intelligence and analytics on trends, deals and companies across all FinTech sectors around the world.
