You hear about the OCR in the news whenever the Reserve Bank makes an announcement, and it can move your mortgage and savings rates. Understanding what it is, and how it flows through to you, helps you make sense of rate changes and plan around them rather than being surprised.
The Reserve Bank reviews the OCR on a schedule through the year. Its main job is to keep inflation within a target range. The OCR is its main lever: changing the cost of money cools or warms the economy.
The OCR is the rate that affects what banks pay to borrow and what they earn on funds overnight. Banks then set their own retail rates, the mortgage and savings rates you see, influenced by the OCR but also by competition and their funding costs.
When the OCR rises, banks usually raise mortgage rates, so repayments on floating loans go up, and fixed rates offered to new borrowers tend to rise too. When the OCR falls, the reverse usually happens. The effect on you depends on whether you are on a floating or fixed rate.
| Your Loan | Effect of an OCR Change |
|---|---|
| Floating rate | Changes fairly quickly with rate moves |
| Fixed rate | No change until your fixed term ends and you refix |
Savers feel the OCR too. A higher OCR generally means better savings and term deposit rates, while a lower OCR means leaner returns on cash. So the same move that raises borrowing costs can reward savers, and vice versa.
The OCR shapes the direction of retail rates, but your exact mortgage or savings rate also depends on competition between banks and their own costs. That is why bank rates do not always move by exactly the same amount as the OCR.
The Reserve Bank's main goal is keeping inflation, the general rise in prices, within a target band. The OCR is how it leans against the economy.
Changes take time to work through the economy. The Reserve Bank is trying to steer where inflation will be in the future, not just today, which is why decisions can seem to lag what you feel in the moment.
You do not need to predict the OCR, but knowing the trend helps. Our NZ Interest Rates reference and the Reserve Bank's announcements show where it sits and the likely direction.
Bank rates are influenced by the OCR but also by competition and funding costs, so they do not match it move for move.
Nobody reliably predicts rates. Decisions based on your own budget and risk comfort beat trying to outguess the market.
A fixed rate shields you for now, but when it ends you refix at whatever rates are then. Plan for that.
Final word: the OCR is the Reserve Bank's main tool for managing inflation, and it strongly shapes the mortgage and savings rates you pay and earn. It sets the direction, not your exact rate. Follow the trend, plan for refix risk, and make decisions on your own budget. This is general information, not advice; rates change frequently, so check current figures.
