The banks reportedly under investigation are Bank Hapoalim, Bank Leumi le-Israel BM and Mizrahi-Tefahot. According to a letter issued by US Deputy Attorney General James Cole, the three Israeli banks have until September 23 to produce broad statistical information on their Swiss operations with US clients. However, there was no indication on the possible consequences in the event that the banks fail to do so.
In response, a spokesman for Bank Leumi told Reuters via email that the company was cooperating fully with US authorities. On the other hand, spokespeople for Mizrahi Tefahot and Bank Hapoalim did not respond to requests for comment.
Along with the three Israeli banks, Deputy Attorney General James Cole also wrote to seven other Swiss banks requesting their information in regards to US tax evaders.
Last week, Swiss banking authorities agreed to hand over US citizens' bank information over to the US government after a prolonged period of pressure from Washington.

The shift to Israel from Switzerland could signal the broadening of a landmark probe by the US Justice Department that began in 2007 with UBS AG, Switzerland's largest bank.
Datan Dorot, a tax lawyer in Miami who represents US clients of Israeli banks, told Reuters that bankers from an Israeli branch of Bank Leumi had called his clients about six weeks ago, telling them to close their accounts because of the increased level of scrutiny.
