The latest rankings, known as the Global Financial Centres Index (GFCI), looks at 98 business districts around the world.
Results are based on an array of factors. London's qualities were assessed on the city’s human capital, financial development, business environment and infrastructure. London topped the competition in each.
But warning signals to city financial types include risks from the never ending saga of EU membership and the Conservative government’s efforts to thwart migration.
Mark Yeandle, Z/Yen firm spokesperson said:
“Soundbites coming out of Westminster about restricting immigration add uncertainty. You can’t have an international financial centre without an international workforce.”
The authors said The City benefited from renewed political-economic certainty following the recent General Election.
The rankings emphasised London’s position as head of the European pack in the global financial zone stakes.
Zurich is the only other European city to make the top 10.
