Central bank base rates

The record of MNB and ECB base rate quotations that default interest is calculated from. Manual entry and download from the central bank.

This screen keeps the base rate of the Hungarian National Bank (forint) and the European Central Bank (euro) day by day. Default interest is calculated from these quotations, so the series must be complete.

Where to find it

Master datas → Central bank base rates. The list shows Central bank, Currency, Valid from, Time, Rate (%/year), Source (API or Manual) and Note.

Under the Hungarian Civil Code (Ptk. 6:155. §) the base rate of the central bank issuing the currency of the debt applies.
