A Quick Note On Interest Rates

The last couple of years have been a rollercoaster for Australian borrowers. We’ve gone from record‑low rates to a sharp tightening cycle, and now into that uneasy phase where everyone is asking, “Are we done yet?” For mum and dad borrowers juggling mortgages, school fees and rising grocery bills, all the talk of cash rates, inflation targets and yield curves can feel pretty detached from the reality of making repayments each month.

Let’s strip it back. The Reserve Bank lifted rates aggressively to bring inflation under control. That’s filtered through to variable home loan rates and, with a lag, to fixed rates as well. A lot of borrowers rolled off ultra‑cheap fixed loans onto much higher rates – what the media called the “fixed rate cliff”. The worst of that adjustment has now worked through the system. Arrears have ticked up, but they haven’t exploded. House prices wobbled, then stabilised in many areas as supply constraints and population growth kicked back in.

Looking forward from mid‑2025, the story is less about big new hikes and more about how long we stay around current levels. The RBA doesn’t want to re‑ignite an inflation problem by cutting too early, but it also doesn’t want to crush households to the point that spending and employment fall off a cliff. That means we’re likely to sit in a band where rates feel uncomfortably high if your memory is anchored to 2020–21, but not extreme by longer‑term historical standards.

What does that mean if you’ve got a home loan or an investment loan? A few practical points:

  • Variable rates give you flexibility, but you need to budget for some bumps. Even if the next moves are down, they may not be fast or large. Treat any cuts as a bonus, not a guarantee.
  • Fixing a portion of your debt can make sense if you value certainty over squeezing out the last bit of savings. The “perfect” timing is only obvious in hindsight. A sensible split between fixed and variable is often less stressful than trying to pick the top or bottom.
  • Offset accounts and redraw remain underrated tools. Every extra dollar you park there works as an immediate, risk‑free “return” equal to your interest rate. In a higher‑rate world, that matters more than ever.

For investors, the equation is a bit different. Higher rates make negative gearing less comfortable and put more pressure on rental yields to do the heavy lifting. At the same time, limited housing supply and strong migration are supporting rents in many markets. The key is to run the numbers honestly: can the property carry itself at today’s rates plus a margin, and would you still be happy owning it if capital growth is slower from here?

If you look back over this period in a few years’ time, the people who come out in decent shape will likely be those who didn’t chase the absolute lowest rate at all costs, but instead focused on structure, buffers and flexibility. They’ll have:

  • Kept a cash buffer rather than maxing out borrowing capacity.
  • Used offset accounts properly.
  • Chosen lenders who are responsive if things get tight, rather than just the cheapest headline rate.

Interest rates will move up and down over the cycle – they always do. What you control is how fragile or resilient your position is when they do move. In that sense, 2023–25 has been a stress test in real time. If you’ve made it through so far, you’ve already done something right. From here, it’s about tightening up the basics and making sure the next shift in rates, whether up or down, doesn’t dictate your whole life.
