LONDON, Feb 15 (Reuters) - Investment banks have warned M&A teams in Britain they cannot pitch business to clients in the European Union if there is a no-deal Brexit without an EU "chaperone" sitting in on their meeting, sources familiar with the matter told Reuters.
Banks including Nomura and Credit Suisse have told dealmakers in London that in a no-deal Brexit scenario they would have to loop in EU colleagues when talking to customers in continental Europe about specific advisory work and regulated products like loans or bonds.
Even cold-calling of company executives to pitch for new business out of London could raise eyebrows among EU regulators if Britain crashes out of the EU without a deal, the sources said.
"There is a whole bunch of things people have to do in the course of an M&A transaction which require regulation," Simon Gleeson, a financial services partner at Clifford Chance, said.
"The problem is that at the start of the discussion you have no idea how you're going to finance the deal and technically you should tell clients every five minutes 'oh, I can't do this, I can't do that,' which is a bit worrying," Gleeson said, referring to what could happen if there is no Brexit deal.
A Credit Suisse spokeswoman said the Swiss bank was working to maintain access to EU clients and markets by using its existing infrastructure in the event of a hard Brexit.
"Discussions with relevant regulators, employees and key stakeholders continue but as we have previously stated, our solution will involve multiple locations, including Madrid, Frankfurt and Luxembourg," she said.
"London will remain a key part of the bank's footprint even after the UK's exit from the European Union," she said.
Nomura declined to comment.
Prime Minister Theresa May suffered another parliamentary defeat on Thursday in her attempt to win backing for a Brexit deal that would mean business as usual for bankers until the end of 2020.
But with Brexit due in just over 40 days and no deal in sight, bankers are having to face up to what a no-deal Brexit will actually mean and make contingency plans.
"If Britain crashes out of the EU, even pitching ideas to EU clients is unchartered territory," a London-based M&A banker at a European investment bank said.
"We will need a chaperone who is cleared by EU regulators to witness our conversations."
REVERSE SOLICITATION
M&A bankers have until now seen their jobs as Brexit-proof because unlike other banking roles, including selling and trading equities or bonds, dealmaking is effectively unregulated.
