The paper discusses issues connected with the use of selected indices (WIBOR, WIBID, WIRON,
POLONIA) as benchmarks for bank loans. In the introduction, the author addresses the problem
of manipulation of rates, which are characterized by the forecasting of interest rate values. The
following part of the paper analyses the differences in benchmarks’ construction, describes their
operation, methods of setting and use. It also outlines their behavior over time. Subsequently, issues
relating to the application of WIBOR, WIBID, POLONIA, WIRON as benchmarks for consumer loans
are presented. They have been compared to a sample bank offer based on a fixed interest rate. The
final conclusions outline the possible effects of various benchmarks on borrowers, and compare
the situation of the Polish banking offer for fixed-rate loans with other countries. The possible
effects of new regulations in the context of the share of fixed-rate loans in the credit market are
also described.
