The New Zealand Financial Markets Authority (FMA) has published information showing the size and timing of interest rate changes made by major financial institutions after changes in the Reserve Bank of New Zealand’s Official Cash Rate (OCR). The dataset focuses on when changes take effect for new and existing customers of floating rate mortgages and on call savings accounts. The FMA requested information from eight financial institutions that account for around 98% of New Zealand housing loans. The published information is intended to provide a centralised view of participating institutions’ rate movements, highlighting both the magnitude of changes and the time taken to implement them across the two products for different customer cohorts.
