Britain and the European Union agreed a new post-Brexit financial services pact on Friday that will allow them to co-operate on regulation but does little to improve the City of London’s access to the bloc.Britain’s finance ministry said the two sides have agreed terms on a “Memorandum of Understanding” that will set the conditions for how regulators from the EU and Britain share information.

However, Brussels has said the MoU will not automatically lead to Britain’s large financial industry being able to sell a wide range of products and services to EU clients again.

Industry experts said while the framework was useful, it was unlikely to rekindle anything like the kind of access banks and brokers had to the EU before Britain left the bloc.

Brexit has already put a dent in Britain’s financial industry and a City of London official has described the framework as a “talking shop”.

“This is unlikely to offer solid foundations for bulk cross border business,” said Simon Morris, a financial services partner at law firm CMS.

In January, more than 6 billion euros in daily share trading left London for Amsterdam, along with swathes of trading in derivatives.

In a further potential blow to Britain’s financial services might, Brussels is now considering forcing the clearing of euro swaps, still dominated by the London Stock Exchange’s LCH arm in London, to move to the bloc.

Friday’s MoU agreement is similar to what the EU already has with the United States for arranging regular, informal and non-binding meetings of financial regulators to discuss new rules and air any disagreements.

So far, the EU has declined to grant any long-term direct access for financial firms from Britain, saying this week that it was in no rush.

“Overall, for investors in UK financial services, a greater degree of cooperation between Europe and the UK can only be seen in a favourable light,” said Alan Custis, head of UK equities at Lazard Asset Management.

“But it still feels as though the UK needs to continue to plough its own furrow in case there is a change of heart.”

Jonathan Hill, a former EU financial services commissioner, said this week that Britain should not sit around for access, known as equivalence, but focus on making the City more attractive to international investors.

“Achieving a form of equivalence with the EU is essential but it should not detract us from the real challenge: making London and other financial capitals in Europe more competitive relative to the fast growing US and Asian markets,” said Daniel Pinto, chief executive of Stanhope Capital.

Fact Box

Britain left the European Union in January and its 130 billion pound ($179.17 billion) financial services sector lost direct access to the bloc, which had been its biggest customer, worth about 30 billion pounds a year.

The relationship helped cement London’s position as one of the world’s biggest financial centres and as a major contributor to British tax revenues.

The following details how the City of London’s ability to access the EU market and serve clients in the bloc has changed.

Financial services were not part of the EU-UK trade deal that came into effect in January. Blanket access for British financial firms to the EU has ended and any future access will depend on an EU system known as equivalence.

The pact sets up a forum, similar to what the EU already has had for years with the United States. It will provide a space for informal and non-binding discussions between UK and EU financial regulators, but not negotiate market access.

This refers to an EU system that grants market access to foreign banks, insurers and other financial firms if their home rules are deemed by Brussels to be “equivalent”, or as robust as regulations in the bloc.

It is a patchy form of access that excludes financial activities like retail banking. It is a far cry from continued “passporting”, or full access, that banks lobbied for in the aftermath of the 2016 British referendum vote to leave the EU.

Access under the system of equivalence can be withdrawn at one month’s notice, making it unreliable, but Britain hopes the new regulatory forum can help persuade Brussels to make the system more predictable.

Brussels has only granted equivalence so far for two activities: derivatives clearing houses in Britain since January for 18 months, and settling Irish securities transactions until June.

Brussels says it is in “no rush” to grant equivalence given that it wants to build up its own capital markets to cut reliance on the City and see how far Britain wants to diverge from rules used in the bloc.

Faced with limited or no direct access, financial firms in London have already moved 7,500 jobs and over a trillion pounds in assets to new EU hubs to avoid disruption to EU clients.

Trading euro stocks, bonds and derivatives have left London, turning Amsterdam into Europe’s biggest share trading centre. Britain and the EU have agreed that asset managers in London can continue to pick stocks for funds in the EU.

No. To help maintain London as a global financial centre Britain is allowing EU firms to stay for up to three years, in the hope they will apply for permanent UK authorisation. Britain is also unilaterally allowing financial firms in the EU to offer selected services like credit ratings directly to British customers.

Britain has allowed UK firms to use derivatives trading platforms in the bloc to avoid ruptures in business with EU clients.

Brussels says it won’t grant market access until it has a clear idea of how far Britain wants to diverge from financial rules inherited from the bloc, fearing that the City will end up with a competitive edge over the bloc’s banks.

Britain has said it won’t apply some EU rules, will tweak others like insurance capital norms, and will introduce its own version of pending European regulation for investment firms.

It is also easing listing rules, making Britain more attractive for fintechs, and due to publish proposals to make the capital market more globallly attractive. It has already started by easing curbs on “dark” or anonymous share trading, a practice EU countries distrust.

Britain insists it won’t lower standards and will stick to any rules agreed at the global level.

For now, no. London still has a towering lead over rivals Frankfurt, Milan and Paris when it comes to trading stocks, currencies and derivatives and playing host to asset managers.

Financial firms say shifting more capital out of London than is necessary under Brexit would cause unnecessary and costly market fragmentation.

But in the longer term, if the EU takes a tough line on equivalence and its financial centres reach a critical mass in trading key asset classes, the attractions of London as a financial hub would diminish.
