The City of London is weeks away from being free of the European Union’s rules, but its status as a global financial hub still rests on an obscure process controlled by politicians in Brussels known as “equivalence.” The EU has granted one main equivalence decision to the U.K. this year -- but there are about 40 more to go before it’s clear how much investment banking business can stay in Britain, and the EU’s in no rush.

1. What does ‘equivalence’ mean?

Generally speaking, it’s Nation A accepting that Nation B’s rules are as strict as its own and letting Nation B’s companies do certain business in its territory. For the EU, the European Commission determines whether a non-member’s rules are equivalent to its own in a given area.

2. What’s the worry about equivalence?

Beside the criticism that it’s a byzantine, patchwork system, the main concern is that the commission can unilaterally withdraw equivalence, and at short notice. The British have pressed for a longer notice period for withdrawal.

3. Is that the only concern?

More broadly, EU and U.K. politicians are under no obligation to maintain close ties with each other. Commission President Ursula von der Leyen has declared “all will change” in the City of London’s relationship with the EU. As the two sides continue to struggle to reach a separate trade agreement for when the post-Brexit transition ends on Dec. 31, 2020, financial companies worry that equivalence decisions have been sucked into the wider political battles.

4. Has that happened before?

Ask Switzerland. When talks about the Swiss relationship with the EU didn’t advance to the bloc’s liking, the commission refused to extend equivalence covering market access to the nation’s stock exchange. Swiss shares were barred from trading on EU exchanges in mid-2019.

5. Does the U.K. really want equivalence?

The U.K. has increasingly made clear that it will set its own rules and may diverge in places from the EU’s approach. Equivalence “is still something worth having, but it’s not worth having on any terms,” Bank of England Governor Andrew Bailey told U.K. lawmakers in September. The central bank also recently estimated that equivalence findings would cover only about 10 billion pounds ($13 billion) of finance revenue in the U.K.

6. Is there much wiggle room?

Britain argues that it should keep access to financial markets from the outset since it’s so closely integrated with the EU as a decades-long member. The U.K. also wants flexibility in how financial firms are policed, arguing for “outcomes-based” equivalence even if the wording of its rules doesn’t precisely tally. The commission, however, says decisions on market access won’t be subject to negotiations and that it will protect its own interests.

7. So it’s an uphill struggle for the U.K.?

Yes, for both winning and keeping equivalence. Since the 2016 Brexit referendum, policy makers in Brussels have been tightening the rules. For example, the EU now has greater powers to inspect and scrutinize derivatives clearinghouses -- giving it authority over the British firms that handle the bulk of euro-denominated contracts. The commission has also indicated the U.K. can expect close monitoring once equivalence has been granted, to make sure that the two sets of rules don’t drift apart.

8. Which equivalence decisions matter most?

The most important decision for financial stability has already been granted, allowing European firms to continue using London’s dominant clearinghouses. The decision only lasts until the end of June 2022, and the EU is planning a more significant review that could eventually force clearing business to relocate to the bloc. The EU has maintained that it’s in no rush to grant equivalence decisions for derivatives- and stock-trading or to give a broader pass to portfolio management, investment advice, underwriting and trade-execution.

9. What isn’t covered by equivalence?

Core banking activities such as deposit-taking, investment services to retail clients and syndicated and other cross-border lending services. If U.K.-based banks want to continue those lines of business, they’ll most likely need to do so from offices in the EU -- hence the recent shift of some operations to Frankfurt, Paris, Dublin and other cities. Banks are now moving more executives and banking business, with JPMorgan Chase & Co. planning to transfer 200 billion euros in assets to Frankfurt.

10. How many jobs are at stake?

Initial projections of a banking exodus from London, costing hundreds of thousands of jobs, proved overstated at worst and premature at best. Wall Street banks are among firms pressing the British to secure equivalence or else see jobs shift to Europe. EY, a consultancy, said about 7,500 jobs are moving.
