According to the FSC in its announcement dated 13/02/2023:
The WIRON interest rate index has been introduced as a component of performance fees (variable remuneration) in the first investment funds. The required amendments to the statutes have already been approved by the FSC. Thus, WIRON has become an interest rate benchmark index.
Banks may also use the WIRON benchmark index to determine the interest rate on consumer loans or mortgages.
