NEW YORK (WCBS 880) - There is talk of the big Swiss bank UBS moving its North American headquarters from Stamford, Connecticut back to New York City.

UBS left New York City 15 years ago and has reportedly been looking at the thus far unbuilt Three World Trade Center and at a Brooklyn location.

Asked what it would mean, Mayor Michael Bloomberg had a bullet list.

“More jobs, more tax base, great thing. I’ve been saying for the last ten years there’s a reason to come to New York – not knocking Stamford or any other place,” said Bloomberg. “People want to live here. And, places like Stamford, there’s a great raison d’être to live there, but there’s also one for New York, and I think it depends on who you’re trying to attract for your company.”

Bloomberg said the value proposition of New York is that this is the intellectual capital of the world.

“This is where young people in particular, but also even people my age, want to come. Cultural institutions, the challenge of working with others who are motivated - the best and the brightest. All this builds on itself,” said Bloomberg, who added that there is a reason why New York’s population keeps growing.

UBS has made no final decision.
