Britain will not automatically have direct access to the European Union's financial markets after Brexit, even if it meets all the conditions set out by Brussels, under an EU policy document published on Monday.

Updating its policy on market access for foreign banks, insurers and investment firms, the EU's executive European Commission said countries outside the bloc would not necessarily have market access even if their rules were equivalent. 

Faced with a huge financial center on its doorstep that would be outside the bloc after Brexit, Brussels has begun tightening up equivalence conditions. Britain has said UK rules will be identical on day one of Brexit but this does not give a guarantee of access. 

"It should be noted that equivalence empowerments do not confer a right on third countries... to receive an equivalence determination, even if those third countries are able to demonstrate that their framework fulfills the relevant criteria," the Commission’s policy paper said. 

The policy came as UK insurance lobby London Market Group said on Monday that Britain should seek equivalence for reinsurance. 

Britain and the EU have already agreed in principle that equivalence should form the basis of future EU market access. Yet the paper said requests for equivalence from "high impact" third countries would in future require more detailed and granular assessments.

New rules

For their part, British regulators want new rules to make the system more transparent and predictable, given equivalence status can be withdrawn with 30 days notice. 

The EU executive said it had already made such changes. Yet it showed the impact of its new stance by saying on Monday it would for the first time repeal certain equivalence decisions. 

Banks in the EU will no longer be able to use credit ratings from Argentina, Australia, Brazil, Canada and Singapore because the five countries refused to match new EU rules in the sector. 

In response the Monetary Authority of Singapore said ratings from Singapore could continue to be used by banks and others in the bloc under an alternative EU system that "endorses" them. 

The repeals are unlikely to have a major practical impact but carry symbolic weight just three months before the next scheduled date for Brexit. 

The Commission said there could be a transition period ahead of any future repeals, but it ruled out a radical overhaul of a system embedded in 40 provisions in EU financial rules. 

"The Commission's conclusion... is that it is now generally accepted that it would be extremely difficult to implement a uniform assessment and decision-making process encompassing various areas of equivalence," it said. 

Future determinations would include ongoing checks to ensure third-country rules remain aligned with those in the bloc. Such tighter conditions for equivalence could make it less attractive for Britain, finance industry officials have said.
