Interest rates are back in the headlines again, and for a lot of business owners, it’s starting to feel like everything is getting more expensive at once.
So, it’s a fair question to ask:
Is this going to push up my insurance premiums too?
Short answer — not in the way most people think.
There’s definitely a connection between interest rates and insurance, but it’s not direct. And if you rely on the headlines alone, it’s easy to end up with the wrong idea about what’s actually driving your costs.
First things first — insurance doesn’t move with interest rates
One of the biggest misconceptions we see is that insurers simply increase premiums when rates go up.
That’s not really how it works.
Insurance pricing is driven by things like:
- how much claims are costing
- how often claims are happening
- what it costs to rebuild or replace something
- how much risk sits in a particular industry or location
That’s why, over the past few years, premiums have been climbing even before the latest round of rate increases. Floods, bushfires, supply chain issues — those have had a much more immediate impact than interest rates themselves.
So if you’re expecting a one-to-one relationship, it’s worth resetting that assumption early.
Where interest rates do start to matter
Even though they don’t directly set premiums, interest rates still play a role in the background. You just have to follow the chain a bit further.
It usually comes back to inflation
Rate rises are generally a response to inflation. And inflation does hit insurance in a very real way.
When costs increase across the economy:
- building materials go up
- labour becomes more expensive
- repairs take longer and cost more
From an insurer’s point of view, that means every claim is potentially more expensive than it was 12–24 months ago.
Over time, those costs feed back into premiums.
So it’s less about interest rates themselves, and more about what they’re reacting to — and what that does to the cost of claims.
Insurers are also investors (which people often forget)
Most insurers aren’t just holding premiums in a bank account. They’re investing that money, usually in conservative assets.
When interest rates are higher, those investments can perform better. That can take a bit of pressure off pricing, at least in theory.
But in the current environment, that benefit is often outweighed by rising claims costs and ongoing risk factors.
So yes, it helps — just not enough to cancel everything else out.
The bigger impact is how it affects you, not them
Where interest rates really start to show up is in day-to-day business decisions.
As borrowing becomes more expensive, cash flow tightens. Margins get thinner. And suddenly every cost gets looked at more closely.
Insurance is usually one of them.
We’re seeing more businesses:
- question whether they need the same level of cover
- look for ways to reduce premiums
- delay reviews or updates
None of that is surprising. But it does create a different kind of risk.
The underinsurance problem (this is the one to watch)
This is probably the most important piece of the puzzle — and it doesn’t get talked about enough.
At the same time as businesses are trying to reduce costs, the actual cost to rebuild or replace assets is going up.
That gap matters.
If your sums insured haven’t been reviewed recently, there’s a real chance they no longer reflect what things would cost today. And in the event of a claim, that shortfall doesn’t just disappear.
It gets absorbed by the business.
Underinsurance isn’t always obvious until it’s too late, which is why it tends to catch people off guard.
So what should businesses actually be doing?
This isn’t a situation that calls for big, reactive decisions. It’s more about staying aligned with what’s changed.
A few things worth paying attention to:
Check your valuations
If it’s been a while since you reviewed replacement costs, it’s worth revisiting. Construction and repair costs have shifted more than most people realise.
Don’t focus on price in isolation
Reducing cover might solve a short-term cost issue, but it can create a much bigger problem later. It’s about balance.
Look at how your policy is structured
Sometimes there are smarter ways to adjust a policy — excess levels, inclusions, or how cover is layered — without simply cutting it back.
Keep reviews regular
In a stable market, you can get away with reviewing things less often. Right now, things are moving too quickly for that.
Cutting through the noise
There’s a lot of commentary around interest rates at the moment, and it’s easy to assume they’re directly driving every cost increase you’re seeing.
With insurance, that’s only part of the story.
Premiums are still being shaped more by claims, risk, and the rising cost of putting things back together after something goes wrong.
Interest rates sit in the background — influencing the environment, but not dictating outcomes on their own.
A more useful way to think about it
Instead of asking “Will interest rates push my premiums up?”, a better question is:
“Does my insurance still reflect what it would cost to recover if something happened?”
That’s the question that actually protects you.
The bottom line
If you haven’t reviewed your cover in the past 12 months, now is a good time to sense-check it.
Not because interest rates have moved — but because everything around them has.
