The European Union cannot decide yet on granting Britain access to the bloc's financial market, even though London and Brussels have agreed a trade deal, a European Commission official says.
While the landmark trade deal agreed on Thursday set rules for industries such as fishing and agriculture, it did not cover Britain's much larger and influential finance sector.
There were hopes the trade deal would pave the way for more access to the EU for Britain's finance industry, but the EU indicated it was in no rush to grant it.
Brussels has only granted financial market access, known as "equivalence", for two financial activities from January 1, when Britain will have left the EU's single market.
The Bank of England has said there could be disruption in markets if no further access is allowed.
Just minutes after Britain and the EU hailed their agreement on trade, the bloc's executive said it wanted a "series of further clarifications" on how Britain will diverge from EU rules after December 31.
"For these reasons, the Commission cannot finalise its assessment of the UK's equivalence in the 28 areas (under discussion) and thus will not take decisions at this point in time. The assessments will therefore continue," the official said.
The City of London finance hub secured no special treatment, leaving it on a par with arch rival New York as the EU seeks to reduce reliance on UK financial services.
The trade deal refers to financial services in the same way as the bloc's other trade agreements, the official said.
Both sides will discuss how they can move forward on equivalence, stopping short of any commitment to grant access, Britain said.
The two sides will also aim to agree by March 2021 a memorandum of understanding on regulatory cooperation in financial services. Countries such as Canada and the United States already have such cooperation.
"There's some good language about equivalence for financial services, perhaps not as much as we would have liked, but it is nonetheless going to enable our dynamic City of London get on an prosper, as never before," said British Prime Minister Boris Johnson.
