FAQ

Is WIBOR being phased out?

Yes — Polish authorities have approved a transition from WIBOR to WIRON, a transaction-based overnight risk-free rate. The original timeline has shifted several times, so check current KNF and GPW Benchmark communications for the latest schedule before assuming specific milestones.

What happens to my existing WIBOR-based mortgage during the transition?

Existing contracts include reference rate fallback provisions and are expected to be converted using a spread adjustment to keep the economic value broadly neutral at the conversion date. The exact mechanism depends on your loan agreement and final regulatory guidance, so review your contract and bank notifications.

Does a lower WIRON mean a lower installment than under WIBOR?

WIRON itself typically prints below WIBOR because it excludes interbank credit risk. However, banks usually add a fixed spread adjustment so that the all-in rate at transition is broadly equivalent, meaning headline benefit is limited.

Can I switch to a fixed-rate mortgage instead of waiting for WIRON?

Most Polish banks offer fixed-rate periods of typically five to ten years. Switching can hedge against benchmark transition uncertainty, but check fees, the fixed rate offered versus current WIBOR plus margin, and whether you might miss out on rate cuts.

Is WIBOR still legally enforceable in current contracts?

Yes — WIBOR remains an authorized benchmark under the EU Benchmark Regulation and continues to be used in existing contracts until the supervised transition completes. Recent Polish court rulings have probed individual WIBOR clauses, but no blanket invalidation has occurred at this time.
