Use of PRIBOR
Interest rates and yields on various financial products are derived from PRIBOR. Specifically, this can include bonds, financial derivatives, corporate or mortgage loans. In the case of mortgage loans, the development of the PRIBOR rate is important for people who have taken out an adjustable-rate mortgage. The interest rate on this mortgage is made up of the PRIBOR rate and the bank’s fixed mark-up.
