“American clients of private bank Julius Bär were told recently that they are the focus of a US tax evasion probe, a Zurich-based daily reported on Tuesday. US tax authorities had requested administrative assistance from their Swiss counterparts to investigate a number of US citizens suspected of having undeclared funds at the Zurich-based bank. The United States has launched investigations into the dealings of around a dozen Swiss banks, including Julius Bär, prompting Switzerland to try to reach an overarching settlement with Washington to provide legal closure for its financial sector.”
