Since the Middle Ages, Switzerland has stood for bank secrecy -- or bank privacy, as the Swiss would insist. In the past month, this foundation of Swiss banking has collapsed under calls for transparency, making Swiss banks seem as outdated as cuckoo clocks. The nearly universal condemnation of Swiss banking is a sign of how quickly our expectations about privacy have changed.

Under pressure from the U.S., Germany, Britain and other high-tax countries, the Swiss agreed to abandon their longstanding protections for depositors accused by their home countries of tax evasion. Until now, countries had to present evidence of fraud, a more serious accusation, before Swiss banks would turn over information about their clients. Switzerland has long been the preferred location for private banking, with more than $2 trillion of the $7 trillion in all offshore deposits located in the country.
