Is it too late to fix your mortgage rate?

The Reserve Bank of Australia has raised the cash rate for the first time in over a decade, so with interest rates already rising, is it too late to lock in your mortgage rate?

There are over a million Australian homeowners who have never experienced an interest rate hike until now. In the 11.5 years since the last Reserve Bank of Australia (RBA) cash rate hike, it had fallen to a record low of 0.10% after years of cuts, only to be raised in May at 0.35%.

It is fair to assume that this first rate hike in May 2022 will not be the last. In fact, three of the big four banks now forecast that the cash rate could climb above 2% by 2023-24.

The latest cash rate forecasts from the big four banks:

  • ABC: 1.60% by February 2023
  • Westpac: 2.25% by May 2023
  • NAB: 2.60% by August 2024
  • ANZ: 2.25% by May 2023

For a whole generation of homeowners who have never experienced an interest rate hike, you may be wondering if you missed the boat to lock in the interest rate on your home loan.

To fix or not to fix after the rate hike

Westpac last month raised its fixed rates six times in 2022, and NAB and ANZ raised their fixed rates for the fourth time since the start of the year. CommBank also raised interest rates for the fourth time since 2022 last month, raising fixed rates by up to 90 basis points in some cases.
