That Revolut — a company that has made little dent in the US, serves 11 million customers in the UK and was started in a fintech incubator in London’s Canary Wharf neighborhood — would consider a New York listing should perhaps be the starkest warning sign for British lawmakers.

Money transfer company Wise on Thursday said it planned to move its primary listing to the U.S. from London, the latest British company to quit the London stock market in search of a bigger valuation elsewhere.

Wise Plc is planning to list its shares in the US, the latest loss for London’s stock market after companies worth roughly $100 billion have shifted their primary listings stateside in recent years.
