As far as I can tell, the dot as the thousands separator is used 
everywhere in Germany, not just by financial institutions or for 
currency amounts.  On the other hand, you can also find books which use 
a (thin) space as the separator (current works, outside cited parts), 
and some people use it in their personal correspondence as well.
