Banking titan Goldman Sachs (NYSE:GS) is the latest institution to send a shudder down the spine of those concerned that the UK's departure from the EU will stall the huge financial services industry, led from London.
The boss of the investment bank said he will be spending "a lot more time" in Frankfurt.
In a tweet, Lloyd Blankfein said: "Just left Frankfurt. Great meetings, great weather, really enjoyed it. Good, because I'll be spending a lot more time there. #Brexit".

The group already leases office space in Frankfurt and employs around 6,000 people in the City.
Earlier this month, it leased space on the 60th floor at a new building in Frankfurt giving it space for up to 1,000 staff, compared to 200 there now.
Frankfurt is of course well known already as a financial hub and Germany - Europe's dominant force.
Standard Chartered (LON:STAN) is committed to expanding or establishing offices in Germany, Citigroup (LON:CITI) plans to bolster its office in Frankfurt, creating 150 jobs, and Morgan Stanley (NYSE:MS) is on track to move as many as 200 staff.
