WIBOR - POLSTR

POLSTR in loan agreements

• POLSTR is set to become the future benchmark used in loan products offered by banks.
• For existing loan agreements, the replacement of WIBOR applicable to a given Customer will take place in accordance with the provisions of the loan agreement and/or the regulations constituting its integral part.
• If the executed loan documentation contains no such provisions, WIBOR may be replaced by virtue of a regulation of the Minister of Finance specifying the appropriate substitute rate. No draft of such a regulation is currently available, and recent announcements from the Polish Financial Supervision Authority (KNF) and the Financial Stability Committee do not indicate any immediate plans for its issuance.
