STIBOR stands for the Stockholm Interbank Offered Rate, the benchmark used as the basis for interest rates in Sweden. It works in a similar way to LIBOR and Euribor, market rates set in London and across Europe.
Like other reference rates, STIBOR is calculated as an average of the interest rates offered by a number of Swedish banks when they offer short term loans to one another. The figure is then used as a basis for charges on loans made elsewhere in the country.
STIBOR is set for a number of different durations of loan. The shortest of these is tomorrow-next and longest six months.
