On 5 May 2026, the Reserve Bank of Australia raised the cash rate by 0.25 percentage points to 4.35%. Eight of the nine board members voted for the rise, with one member voting to hold. This is the third consecutive increase after cuts in late 2025 gave way to renewed inflation pressure.
The RBA cited three factors in its decision: inflation picked up in the second half of 2025, the ongoing conflict in the Middle East has driven fuel and commodity prices higher, and firms are increasingly looking to pass cost increases on to consumers. Governor Michele Bullock described the board as resolute in its commitment to returning inflation sustainably to the 2–3% target band.
The numbers: On a $600,000 variable rate loan, this single rise adds approximately $90 per month to your repayments. Across three rises since the easing cycle reversed, that is around $270 per month added back.
Forecasts diverge significantly right now, reflecting genuine uncertainty about how inflation and the global conflict will play out.
If you are on a variable rate, your lender will typically pass on the full 0.25% within days. Check your lender's communication — some pass on the full amount, others only part of it.
Use this as a benchmark: every $100,000 of loan balance adds approximately $15/month per 0.25% rise. A $500,000 loan adds $75/month. A $700,000 loan adds $105/month. If Westpac is right and rates rise to 4.85%, that is another $150-$210/month on those same loan sizes on top of today's rise.
Fixed rates have already moved. Most lenders priced in further rises before this meeting, so the gap between variable and fixed has narrowed. Fixing now gives certainty against further rises but means you miss out if rates peak sooner than Westpac expects.
The pragmatic answer for most borrowers: a split loan. Fix 50–60% of your loan to cap your worst-case scenario, keep the rest variable to benefit from any future cuts. Lendology can model the exact dollar difference for your specific situation.
Competition among lenders for refinancing business remains fierce despite the rate rises. If your current loan rate starts with a 6 or higher, there is a high likelihood a better deal exists. Lendology's refinancing review compares your existing rate against 60+ lenders at no cost — and if we can save you money, we will show you the numbers before you commit to anything.

The RBA cash rate is 4.35% as of 5 May 2026, following three consecutive increases of 0.25% each. This is the highest the cash rate has been since mid-2024.
On a $600,000 loan, each 0.25% rise adds approximately $90 per month to repayments. On a $750,000 loan, the impact is around $112 per month. If rates rose 0.75% in total over three meetings, that is $270 per month on a $600k loan.
Westpac economists are forecasting two further increases — to 4.60% in June and 4.85% in August 2026. CBA economists expect rates to hold from here. The outcome depends heavily on whether inflation continues to pick up and how the Middle East conflict affects fuel and food prices.
Fixing locks in certainty but means you miss out if rates fall sooner than expected. Staying variable keeps you exposed to further rises in the short term but lets you benefit if and when rates drop. A split loan — part fixed, part variable — is often the pragmatic solution. Book a chat with Lendology to model both options with your actual numbers.
