I’m always a bit loathe to actually go as far as recommending any institution, but has anyone considered offshore. I have used many, for many years, and one of the best is Anglo Irish, because their rates are almost always consistently higher (US$ 4.75%). http://www.angloirishbank.ie/Personal_Savings/Interest_Rates/dollar.html They are an asset management bank so no retail facilities, and of course the Irish Government has guaranteed all deposits. It may be worth checking that this does cover foreign depositors, and not just Irish taxpayers, who after all would foot the bill. Their core business is commercial real estate so some may wish to err on the side of caution, but they claim only a small indirect exposure to US subprime mortgages. However, their stock price has seen quite big dips recently, but this is probably largely attributable to the general trend.
