If you've just received a letter from your bank increasing your mortgage repayments — you're not alone. The Reserve Bank of Australia lifted the official cash rate to 4.35% in May 2026, the third rate hike this year, following increases in February and March.
For homeowners on variable rate mortgages, this means another jump in monthly repayments. On a $600,000 loan, you could now be paying as much as $272 more per month compared to the start of this year.
Naturally, the question on every borrower's lips is: should I fix my home loan rate now before it goes any higher? It's a smart question — but the answer isn't one-size-fits-all. In this article, we break down what's happening, what the banks are predicting, and how to think through the right decision for your situation.
Key Takeaway: Whether to fix, stay variable, or split your loan depends on your savings buffer, repayment plans, and how long you intend to stay in the property — not just the current cash rate. Get a personalised assessment before deciding.
What Just Happened With the RBA?
In May 2026, the Reserve Bank of Australia increased the official cash rate by 0.25 percentage points to 4.35%. This follows rate hikes in February (to 3.85%) and March (to 4.10%), making it three increases in the first five months of the year.
Here is how the 2026 hikes have impacted a typical $600,000 variable rate mortgage:
| Rate Decision | New Cash Rate | Monthly Increase | Running Total |
|---|---|---|---|
| February 2026 | 3.85% | +$91/mth | +$91/mth |
| March 2026 | 4.10% | +$91/mth | +$182/mth |
| May 2026 | 4.35% | +$91/mth | +$272/mth |
| Total 2026 YTD impact | +$272/month on a $600,000 loan | ||
What Is the Difference Between Fixed and Variable?
Before making any decision, it helps to be clear on what you are actually choosing between:
🔒 Fixed Rate
- Rate locked for 1–5 years
- Repayment certainty every month
- Protected from further RBA increases
- Extra repayments capped ($10K–$30K/yr)
- Break fees if you sell or refinance early
- Miss out if rates fall
📈 Variable Rate
- Offset account access
- Unlimited extra repayments
- No break fees — refinance anytime
- Benefit when rates eventually fall
- Rate rises with RBA decisions
- Repayment uncertainty
What Are Rates Sitting At Right Now?
As of May 2026, competitive variable home loan rates start from around 5.08% p.a. for owner-occupiers, while the market average sits closer to 6.45% p.a. — meaning many borrowers are paying significantly more than they need to.
It is worth noting that three of the four major banks currently have their fixed rates sitting above their variable rates. Banks price fixed rates based on where they expect the cash rate to head, so higher fixed rates signal the banks expect rates to continue rising before eventually falling.
This does not mean you should avoid fixing — it means the cost of certainty already reflects some of those expected future hikes. Getting a rate review from a broker who compares across 30+ lenders is the best way to understand where your rate sits relative to the market.
What Do the Major Banks Predict for the Rest of 2026?
The four major banks are not aligned on the outlook — which is part of what makes this decision complex:
| Bank | Forecast for Remainder of 2026 | Predicted Peak |
|---|---|---|
| Westpac | Two more hikes — August & September 2026 | 4.85% |
| CBA | Hold — August hike risk if inflation persists | 4.35% base case |
| ANZ | Hold — acknowledges further hike risk | 4.35% base case |
| NAB | No further hikes forecast | 4.35% |
If Westpac's forecast is correct, a $600,000 variable rate mortgage could face a further +$180/month in repayments by September 2026 — on top of the $272 already absorbed this year.
Should You Fix Your Home Loan Rate?
Whether fixing makes sense depends entirely on your personal situation. There is no universal right answer:
Fixing may suit you if:
- You need repayment certainty on a tight budget
- You don’t have large savings in an offset account
- You’re not planning to sell or refinance in 2–3 years
- The peace of mind has real practical value to you
Staying variable may suit you if:
- You have strong savings in an offset account
- You plan significant extra repayments
- You may need to sell or refinance before the term ends
- You believe rates are near the peak
What About a Split Loan?
A split loan — fixing a portion and leaving the rest variable — is one of the most commonly recommended structures in the current environment. Here is an example on a $600,000 loan:
The exact split depends on your savings, income stability, and future plans — which is exactly what a mortgage broker can model for you at no cost.
What Should Melbourne Homeowners Do Right Now?
Whether you own in Brunswick, Keilor, Niddrie, or anywhere across Melbourne and Geelong, the practical steps are the same:
- Check your current rate. Many borrowers are sitting on rates of 6.5% or more — often without realising better options are available across 30+ lenders.
- Get a break fee estimate. If you are on a fixed rate, ask your lender for the exact break cost before assuming you are locked in.
- Review your offset balance. Significant savings in offset can reduce your effective rate below many fixed options even in a rising-rate environment.
- Don’t decide based on fear alone. Locking in a fixed rate near the peak of a cycle is not always the right call — the numbers need to stack up for your specific situation.
- Speak with a mortgage broker. A broker can model both scenarios against your loan balance, lender, income, and goals — at no cost to you.
