Because the double-decker cut took the market by surprise, those swap rates fell fast.

Within 38 minutes of the announcement, the one-year swap rate dropped about 0.12%.

ANZ’s 1-year interest rate already fell 0.26% last week (from 4.75% to 4.49%).

I expect it to drop another 0.1 – 0.15% over the next 1–2 weeks.

That’ll take the 1-year rate down to 4.35% (if I’m right).

Here’s how this investor will save $15,400

A year ago today, ANZ was advertising 6.19% for its 1-year mortgage rate.

Today it’s 4.49%.

Interest Rates

And if it gets down to 4.35% … that’s a 1.84% drop.

So your weekly payment could fall from $706 to $584 a week. That’s based on a $500k mortgage that you’re paying off over 30 years.

That’ll save you $122 a week.

But if you’ve got more debt, you could save even more.

My colleague, Ed has a $1.1 million mortgage that’s coming up for refix in December.

He’s currently paying 5.75%. If rates drop to 4.35%, that’s a 1.4% cut.

He’ll save $15,400 a year, or $296 a week.

It’s a lot of money!

Now, I get that not everyone has $1.1 million mortgage. But this is the kind of number-crunching the Reserve Bank want people to do.

They want people to reassess their household budgets so they spend more and stimulate the economy.

Here’s what the OCR cut means for house prices

Lower interest rates should also help house prices rise.

Because lower interest rates often mean the bank will let you borrow more. And you can take out a bigger mortgage, while making the same repayment.

Now, house prices tend to get a boost in Spring and Summer anyway.

The REINZ House Price Index ticked up 0.3% in August. Cotality reported a modest increase in house prices in the 3-months to September.

It won’t be a full-blown property price boom. But, it could be a turning point.

Think of these lower rates as a tailwind rather than a take-off.

This is where the OCR could go next

The Reserve Bank will be back in late November. That’s for their last OCR announcement for the year.

The central bank has said that: “The [Monetary Policy] Committee remains open to further reductions in the OCR”

That means the OCR will likely be cut another 0.25% in November.

There could even be another cut coming in February 2026.

That could take the 1-year rate within spitting distance of 4%.

That’d be good for borrowers, property investors and house prices.
