NAB slashed the advertised rates on some of its Tailored Home Loan products on Monday, making it the first of the big four banks to cut interest rates in 2024.

It's a positive sign that those behind the major brands expect interest rates to drop in the coming years.

Eligible homebuyers and refinancers signing onto the NAB product for a three-year fixed rate period can now realise the lowest advertised rate of any mortgage in any of the big four banks' line up: 5.99% p.a.

To be eligible for that rate, a borrower must be an owner-occupier making principal and interest repayments with a loan-to-value (LVR) ratio of 70% or less.

Changes implemented are as follows:

Product LVR Change New rate (p.a.) Comparison rate* (p.a.)
NAB Tailored Home Loan
Three years fixed
≤60% -60bp 5.99% 6.64%
NAB Tailored Home Loan
Three years fixed
60-70% -60bp 5.99% 6.64%
NAB Tailored Home Loan
Three years fixed
70-80% -60bp 6.04% 6.80%
NAB Tailored Home Loan
Three years fixed
≥80% -60bp 6.04% 6.80%

The new rates compare favourably to the 5.99% p.a. interest rate (7.86% p.a. comparison rate*) advertised for borrowers agreeing on a three-year fixed rate period with NAB's Choice Package, principal and interest home loan – previously the lowest rate in NAB's mortgage suite.

How do NAB's new fixed rates compare to other big four banks'?

After NAB, the lowest fixed rate from another big four bank is advertised by Westpac.

It promises a rate of 6.49% p.a. (comparison rate* 7.57% p.a.) for those with LVRs of up to 70% committing to a two-year fixed rate period and signing onto its Premier Advantage Package.

Meanwhile, 6.59% p.a. is the lowest fixed rate advertised by both CommBank and ANZ.

While such rates might be enticing, the market is still shying away from fixed interest rates.

Fixed rate mortgages made up just 1.8% of the $56.8 billion of home loan lending occurring in May, according to Australian Bureau of Statistics figures.

Which big four bank offers the lowest variable interest rate?

With that in mind, which of the big four banks are currently advertising the lowest-rate variable home loans for owner occupiers making principal and interest repayments? Here's how the quartet's variable rates compare to one another's:

Bank Product with the lowest variable rate LVR Advertised interest rate (p.a.) Comparison rate* (p.a.)
CommBank Digi Home Loan ≤60% 6.15% 6.28%
Westpac Basic Variable Home Loan (special offer) ≤70% 6.44% 6.76%
ANZ Simplicity PLUS home loan ≤60% 6.54% 6.54%
NAB Tailored Home Loan ≤60% 6.79% 6.87%

Interest rates correct at the time of writing

Where does NAB believe the RBA cash rate will go from here

If you were to have time travelled from the year 2020 and landed on this article, you'd be shocked at the height of the interest rates listed above.

It was nearly four years ago that the RBA cash rate – a major influence on lenders' interest rates – was dropped to a record low of 0.1%.

It has since roared to a 12-year high of 4.35% and, out of the big four banks, NAB is the most sceptical of near-term rate cuts.

It isn't forecasting a cash rate cut until May 2025.

From then, it expects the cash rate will fall once each quarter to reach 3.10% in mid-2026.

That's in contrast to CommBank and Westpac, each forecasting a cash rate cut in November, and ANZ which is tipping a February 2025 cut.
