More than ten Swiss banks are in serious trouble in the US for allegedly having helped thousands of clients avoid paying taxes.

Last month, oldest Swiss bank Wegelin became the first casualty as the US assault intensified and the bank has to dispose its non-US business in a bid to protect its assets. Just last week, the bank has also been declared a "fugitive" by a court in New York after it failed to show up for a hearing there.

Governments, which once turned a blind eye to their wealthy citizens’ offshore tax acrobatics, now hungrily hunt every penny in tax revenue as they are strapped for cash now. So the war on banking secrecy is only turning hot.

Though the proposed rule will have far reaching consequences for Swiss banking industry and may even lead to an end of the country’s famed banking secrecy, we believe the decision is a step in the right direction and will keep Swiss their banking system relevant in new tax disclosed world.
