Can you provide any proof for your statement?

Some said it would never happen. They were wrong. The U.S. and Swiss reached a deal that punishes Swiss banks and paves the way for even more transparency. See DOJ: United States and Switzerland Issue Joint Statement Regarding Tax Evasion Investigations. And it takes little imagination to know this will impact even obscure and far-flung countries too. After all, just remember the past and Switzerland’s long tradition of bank confidentiality. Tax evasion is not even considered a crime.

Richard Bloomfield has spent three decades embracing the Swiss way of life. Married to a Swiss woman, the 63-year-old retired pastor speaks Swiss German fluently and admits he does many things “the Swiss way”. In the eyes of wary Swiss banks, however, he's still very much an American.

Last year, the Swiss bank where he held an account for nine years informed him he should take his business elsewhere. Faced with onerous US tax reporting rules set to come into effect in 2014, the bank decided the costs were too great and that cutting ties with Bloomfield and other American customers would be preferable.

They weren’t the only ones coming to this conclusion, Bloomfield learned when he was rejected by another Swiss cantonal bank. “When the fellow heard my name, he said no chance,” Bloomfield tells The Local. “He was very nice. He simply said it’s too complicated, costs too much money, we don’t want to take that risk.” Bloomfield eventually moved his account to the Raiffeisen bank, where he already had a mortgage.

Many Americans in Switzerland, like Bloomfield, are finding the welcome mat gone from the doorstep of their local bank. Some banks are closing the accounts of Americans who live in Switzerland, while others are refusing to grant them mortgages or loans.
