5%: Royal Avenue, Genua. (forins) 
  10%: Genua Embassy, Phedre Road, Ankh-Morpork (dollars)


The only bank in Genua at present, Genua National has a nice comfortable atmosphere only slightly spoiled by tinny Muzac over the magic speakers.  It is also the only bank on the disc to encorporate a vault into the same building.

The embassy in Ankh-Morpork also has a money changer facility which sells forins at a 10% cut and buys them at 11%.
