A Better Question Than "Should I Wait for Rates to Drop?"
What's really happening when rates are in the news
When interest rates are moving — or people think they're about to — one of the most common questions we hear is some version of: "Should I just wait until the OCR drops before I do anything?"
It's a reasonable instinct. But it's also a question that often leads people in circles — because the relationship between the OCR and your actual mortgage rate is more complicated than the headlines suggest.
This is a general guide, not personal financial advice. The aim is to give you a calmer, clearer way to think about the decision — whatever stage you're at.
What is the OCR?
The Official Cash Rate (OCR) is the interest rate set by the Reserve Bank of New Zealand. It's the rate at which banks borrow money from each other overnight — and it acts as an anchor for interest rates across the economy.
When the Reserve Bank wants to slow inflation, it raises the OCR, making borrowing more expensive. When it wants to stimulate spending and growth, it lowers it. Changes to the OCR flow through to mortgage rates, savings rates, and business lending — though not always immediately, and not always equally. Reserve Bank of New Zealand
The OCR is reviewed several times a year, and each announcement is watched closely by lenders, economists, and anyone with a mortgage.
What the OCR actually does to mortgage rates
But knowing what the OCR is doesn't fully answer the question people are really asking: "If the OCR drops, will my mortgage rate drop too?"
The mechanism isn't as simple as "OCR goes down, your mortgage rate goes down by the same amount at the same time."
Why fixed mortgage rates don't simply follow the OCR
There are two types of mortgage rates to understand here.
Floating rates tend to respond fairly directly to OCR changes. When the OCR moves, floating rates often move with it — sometimes quickly.
Fixed rates work differently. They're largely driven by wholesale interest rates (swap rates) — which reflect what financial markets expect interest rates to do over a given period, not just what the OCR is doing right now.
That's why you'll sometimes see:
- Fixed rates move before an OCR announcement
- Fixed rates stay flat even when the OCR changes
- Different fixed terms (e.g., one year vs three years) move in different directions at the same time
In short: watching the OCR headline tells you something — but it doesn't tell you everything about where your fixed rate is heading, or when.
The practical risk of waiting
Waiting for rates to fall can work out. Sometimes it does. But it's worth being honest about what else you're waiting through:
- Pre-approval windows — these have expiry dates
- Property availability — the right property doesn't necessarily reappear later
- Market rate movements — fixed rates can shift independent of OCR announcements
- Life changes — income, expenses, family circumstances, and plans don't pause
The issue isn't that waiting is always wrong. It's that you're not fully in control of the timing — and the wait itself carries its own costs and risks.
A better question to sit with
Instead of asking "Should I wait?", try asking:
"What loan structure would still feel manageable if rates moved either way?"
This shifts the focus from forecasting (which nobody does reliably) to fitness — finding a structure that holds up across a range of scenarios, not just the best-case one.
As Sorted notes, different mortgage types come with different trade-offs across fees, flexibility, and repayment structure. There's no universally right answer — only the one that fits your actual situation. Sorted
A grounded decision framework
These five checks won't give you certainty — but they'll help you make a decision you can stand behind.
1. Budget comfort
What repayment level feels manageable without running your household tight? Start there, not with the headline rate.
2. Buffer
Do you have some breathing room — savings, secondary income, or flexibility in your spending — if things shifted?
3. Income stability
Are you on steady PAYE, self-employed, commission-based, or heading into a transition? Your structure should reflect your income reality, not just your income amount.
4. Time horizon
Is there a reason you might need flexibility in the next one to three years? A move, renovation, family change, or career shift? Factor that in before locking long.
5. The sleep test
Which option lets you sleep — not just on settlement day, but six months in, when the novelty has worn off?
Practical structures that don't require a perfect forecast
You don't need to pick the bottom of the rate cycle to make a sensible decision. Here are a few approaches that give you flexibility without leaving everything open:
- Split loan (part fixed, part floating): locks in some stability while keeping a portion flexible
- Shorter fixed term: builds in a natural review point without committing to a long-term bet
- Floating portion for lump sums: useful if you expect to make extra repayments
- Offset or revolving credit: can be powerful, but only if your cashflow habits genuinely support it — worth understanding clearly before choosing this route
The takeaway
Waiting for the OCR to drop can feel like the sensible move. But fixed rates often move on market expectations rather than announcements — and life doesn't always allow for an open-ended wait.
The calmer approach is to choose a structure that fits your real circumstances: your income, your buffer, your timeline, and your honest comfort with uncertainty.
You don't need to win the forecast. You need a plan that holds up.
