The previous 18 RBA cash rate cuts make it easy to ignore the latest call that interest rates may rise again. But with the possibility of the cash rate returning to mid-2019 levels, it’s important to ask yourself how much an average mortgage holder should expect to pay each month.  How might this rise affect you?

The rising rates may occur sooner than we may expect. This could affect you and your position in the property market, and your accessibility to property purchasing. Understanding the RBA’s announcement will give you a better perspective of your potential challenges.

While the RBA held the official cash rate at 0.10% this month – and reaffirmed its position that it does not expect to lift the cash rate until 2024 – there is growing speculation the next cash rate hike could come as early as late 2022.

In June, Commonwealth Bank and Westpac predicted a rate hike around late 2022 to early 2023. In fact, they expect the official cash rate to hit 1.25% in the third quarter of 2023 and 2024, respectively.

Meanwhile, NAB this week hiked its 2-,3- and 4-year fixed rates by up to 0.10% for owner-occupiers paying principal and interest.

Banks can increase fixed rates as a way of heading off potential RBA rate hikes. The way the banks treat their fixed rates, can give insight into their believed timeline for the RBA’s rate increases. For example, generally, the shorter the term of the fixed-rate that’s increased (ie. if 2-year fixed rates are increased), the sooner a bank may believe the next rate hike will be.

If the big banks’ economists are onto something here, we can theorise how much extra money should you be factoring into your monthly mortgage repayments if the official cash rate rises to 1.25% by 2023/24.

How much extra the average mortgage holder could expect to pay

The first thing to note is that the last time the RBA’s cash rate target was at 1.25% was June 2019.

Modelling from Canstar, published on Domain, shows the average variable mortgage rate would lift from 3.21% to 4.36%, based on the current margin between the two rates.

Now, if you took out a $500,000 loan tomorrow, and the cash rate hit 1.25% in 2024, that modelling estimates your monthly repayments would increase $300 to $2464 per month.

ABC News modelling covers a similar scenario, with repayments up $324 per month.

That’s despite reducing your remaining loan balance to $468,770 after three years of repayments, and assuming the banks only add on the cash rate increase – and not any extra.

And then there’s of course the possibility that further RBA cash rate increases could soon follow.

If, for example, the average variable loan rate increased to 7.04% in 2031, where it was just a decade ago in 2011, Canstar estimates that same borrower who took out a $500,000 loan would pay $900 more in monthly repayments than they do now – even after a full decade’s worth of repayments.

We can run you through your options

It’s hard to imagine that interest rates could rise from the comfort of the current record low cash rate.

In fact, you have to go back as far as November 2010 to when the RBA last increased the cash rate (to 4.75%). We’ve had a run of 18 straight cuts since then.

But the big banks’ economists aren’t basing their modelling, predictions and fixed-term rate increases on nothing so it makes sense to listen to their theories.

If you’re worried about what rate increases could mean for your household budget in the coming years, we can help make sense of all the factors that can make this situation confusing and potentially scary.

That might include fixing your interest rate for two, three, four or five years, or just fixing part of your mortgage (but not all of it).
