The Czech National Bank has published the average borrowing interest rates used to calculate reimbursement of costs for early repayment of certain consumer credit for housing purposes under Article 117a of the Consumer Credit Act. The averages are calculated for rolling periods of three consecutive calendar months and apply to creditors authorised to provide consumer credit for housing purposes. The relevant amended framework for using these averages in early repayment cost reimbursement took effect from 1 September 2024. For this purpose, housing consumer credit is divided into 20 groups. The classification distinguishes purpose-specific loans and building society loans, then separates each by whether the loan is secured by a mortgage, and further splits them across five fixed-rate periods: up to and including 1 year, over 1 year up to and including 3 years, over 3 years up to and including 5 years, over 5 years up to and including 10 years, and over 10 years. The Czech National Bank began publishing the averages in August 2024 through its OBIEE presentation tool and ARAD public database, with the grouping methodology set out in Decree No. 56/2024 Coll.
