Most German banks are in the comprehensive German mutual guarantee fund (Einlagensicherungsfonds). Those that are in this fund guarantee for each customer up to several millions of euro. They have a web site, where you can ask them to send you by e-mail the individual guarantee limit of a specific bank:
http://www.bankenverband.de/html/verband/e...?channel=1018321. choose the bank you are interested in
2. fill in your details, they say they want your real details, but as long as you put in your correct e-mail address and some made-up name&postal address details, it still works.
3. They will send you within a few hours an e-mail to the e-mail address you gave which states that bank's guarantee limit in euro.
Example of that e-mail for e.g. Parex banka:
Bank Sicherungsgrenze EURO
------------------------------------------------------------
Parex banka Aktiengesellschaft 1.500.000
lettischen Rechts, ZN Berlin, Berlin
So the Parex bank in Berlin has a guarantee limit of only 1,5 million euro, most other German banks have a limit in the range of tens of millions of euro.
There are also some banks (e.g. Credit Europe Bank, AK-Bank) operating in Germany that are in the Dutch guarantee fund, which guarantees 100% up to 20,000€ per customer per bank, and 90% of the next 20,000€. The web site with their names is:
http://www.nvb.nl/index.php?p=10803 If you don't find a bank operating in Germany in either of these 2 funds things get a bit hairy. I think there is a law that all banks in the European Union have to be at least in a basic guarantee fund, which guarantees 90% of deposits up to 20,000 euro, but I wouldn't rely on it and would not give my money to any bank not in the comprehensive German or Dutch guarantee funds.
The web sites above are official ones, this one is unofficial:
http://www.vergleich.de/informationen/geld...andsbanken.htmland gives an overview of the guarantee limits for the different countries in the European Union. Just because a bank operates in Germany doesn't mean it is not officially part of a foreign guarantee fund. For example the Advanzia Bank is part of the Luxembourg guarantee fund.
