Banks in Britain are drawing up fresh proposals for how they could access customers in the European Union after Brexit in a bid to influence UK-EU trade talks next year after the Conservative Party's election victory.
With Prime Minister Boris Johnson vowing to take Britain out of the EU on January 31, major banks are set to make a fresh push for access to the bloc.
However their latest plans are a far cry from the near-unfettered access they were initially hoping for after the June 2016 Brexit referendum.
They are proposing instead a basic off-the-EU-shelf model that will allow them to still give advice and sell some products to wholesale clients in the EU from their British hubs, but not serve retail customers.
Banks plan to argue that an existing section of the EU Securities Rules MiFID, known as Article 46, should allow them to have a degree of access, without causing too much opposition in Brussels.
"The international banks want the ability to provide key services and advice to EU customers," said Conor Lawlor, director of Brexit, capital markets and wholesale at UK Finance, a banking trade body.
This plan "would require the EU to activate mechanisms it already has in place", Conor Lawlor said.
The EU is Britain's biggest financial services export market, worth about £26 billion annually, helping London remain a top global financial centre.
Major banks have already set up new hubs in the bloc in anticipation of Brexit, but having a degree of access from London could reduce the amount of capital their EU outposts need to hold, bankers and lawyers say.
Under Article 46 the EU would be required to declare that Britain's rules on "investment services" are similar enough or "equivalent" to the bloc's own rules for access to be granted.
Banks plan to lobby the Treasury to ask Brussels for this type of access. EU regulators would have 180 working days to decide whether to allow it or not.
But the European Securities and Markets Authority (ESMA), which would examine the application, said Article 46 has never been used, meaning tough scrutiny is likely.
The European Commission in Brussels would have the final say.
The Commission said preserving financial stability remains a top priority.
Brussels rejected the UK financial sector's ambitious proposal in 2017 for broad, two-way trade after Brexit, saying Britain could not keep the benefits of the EU single market without obligations like free movement of people, a core red line for Johnson.
Britain's stance towards the EU has also hardened. Johnson does not want Britain tied to EU rules as he thinks this could stop the country being competitive globally.
UK finance minister Sajid Javid has said there will be equivalence agreements in place next year, but bankers fear the process will get bogged down in wider UK-EU trade talks on politically-charged fishing and agriculture.
