Key Point: The Official Cash Rate, or OCR, is the interest rate set by the Reserve Bank of New Zealand. It influences the cost of money in the whole economy. When the OCR rises, banks tend to lift mortgage and savings rates; when it falls, those rates tend to drop. The Reserve Bank moves the OCR mainly to keep inflation in check. It does not control your exact mortgage rate, but it strongly shapes the direction.

Who Sets It and Why

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 a Wholesale Rate

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.

🔗 How It Flows Through to You

Mortgages

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 LoanEffect of an OCR Change
Floating rateChanges fairly quickly with rate moves
Fixed rateNo change until your fixed term ends and you refix

Savings and Term Deposits

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.

Borrowers and savers feel it differently: A rising OCR is tough on borrowers but good for savers; a falling OCR helps borrowers but squeezes savers. Whether a change is good or bad for you depends on which side you are on.

It Is Direction, Not a Direct Dial

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.

📈 Why the Reserve Bank Moves It

Controlling Inflation

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.

If inflation is too high, the Bank tends to raise the OCR
Higher rates make borrowing dearer and saving more rewarding
That cools spending and demand, easing price rises
If the economy is weak, the Bank tends to cut the OCR to encourage activity

The Lag

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.

Following the OCR

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.

💡 What It Means for Your Decisions

For Borrowers

  • Think about fixing versus floating with the rate trend in mind, though no one can time it perfectly.
  • Build a buffer so a rise in rates at refix time does not break your budget.
  • Use our Mortgage Calculator to test how a higher rate would change repayments.

For Savers

  • When rates are high, locking a term deposit can secure a good return.
  • When rates are falling, you might lock in before they drop further.

Common Mistakes

Mistake 1: Assuming Your Rate Moves Exactly With the OCR

Bank rates are influenced by the OCR but also by competition and funding costs, so they do not match it move for move.

Mistake 2: Trying to Perfectly Time Fixing

Nobody reliably predicts rates. Decisions based on your own budget and risk comfort beat trying to outguess the market.

Mistake 3: Ignoring Refix Risk

A fixed rate shields you for now, but when it ends you refix at whatever rates are then. Plan for that.

A Simple Way to Use the OCR

1. Know whether you are mainly a borrower or a saver
2. Follow the OCR trend, not every wiggle
3. Build a buffer for higher rates at refix time
4. Make fixing and saving choices on your budget, not predictions
5. Review when the Reserve Bank changes the OCR

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.
