The Financial Conduct Authority has issued a statement saying that the UK regulatory framework, which mostly derives from EU legislation will remain until future negotiations between the EU and UK.
The regulator said it is in close contact with the firms it supervises as well as the Treasury, the Bank of England and other UK authorities, and it is monitoring developments in the financial markets.
The regulator said: "Much financial regulation currently applicable in the UK derives from EU legislation. This regulation will remain applicable until any changes are made, which will be a matter for Government and Parliament.
"Firms must continue to abide by their obligations under UK law, including those derived from EU law and continue with implementation plans for legislation that is still to come into effect.
"Consumers' rights and protections, including any derived from EU legislation, are unaffected by the result of the referendum and will remain unchanged unless and until the Government changes the applicable legislation."
The FCA concluded: "The longer term impacts of the decision to leave the EU on the overall regulatory framework for the UK will depend, in part, on the relationship that the UK seeks with the EU in the future. We will work closely with the Government as it confirms the arrangements for the UK's future relationship with the EU."
