Rates Are Up Again: What the May 2026 RBA Hike Means If You're Borrowing

Quick Answer

The RBA lifted the cash rate by 25 basis points to 4.35% on Tuesday, the third hike of 2026. The cuts from 2025 are now fully unwound. If you're buying or refinancing, expect borrowing capacity to be around $75,000 lower than it was in February, with repayments on a $736,000 loan up roughly $342 a month over the same period.

What the RBA Actually Did This Week

The Reserve Bank moved the cash rate from 4.10% to 4.35% on Tuesday afternoon. Inflation has been the trigger. March quarter CPI came in at 4.6%, well above the 2 to 3% target band, and the Board signalled it had no choice.

This is the third hike of 2026. It follows moves in February and March that took the cash rate from 3.60% in December to where it sits now. Every cut from 2025 has been undone in less than five months.

What's worth noting is the speed. The pivot from cuts to hikes happened fast, and most borrowers who locked in fixed rates last year on the assumption that the easing cycle was real are now watching their fixed period count down.

Your Borrowing Capacity Just Took a Hit

Each 25-basis-point increase shaves around $25,000 off the borrowing capacity of a typical full-time worker on an average income. Three hikes equals roughly $75,000 less to play with at auction.

For a couple with combined income around $250,000, the gap is bigger. Lenders apply a serviceability buffer of 3% above the actual rate, and as the underlying rate climbs, the assessed repayment used to test serviceability climbs with it. The buffer compounds the effect.

If you got a pre-approval in January or February, treat it as out of date. The number has moved. Lenders will reassess on application, and the figure you're working with now likely overstates what they'll actually approve.

What It Means for Existing Repayments

If you're already in a variable-rate loan, the increase will hit your account within a few weeks. Most lenders pass on the full 25 basis points, though some are slower than others.

On a $736,000 loan (close to the national average for new mortgages), each 25-point move adds about $114 a month. Three hikes this year means around $342 extra each month, or just over $4,100 over a full year.

For investors with multiple properties, that figure scales quickly. A two-property portfolio with $1.5 million in debt is now paying roughly $230 more per month than at the start of 2026. Cash flow that was tight in January is tighter now.

If you have a fixed period rolling off in the next six months, run the numbers on the revert rate before it happens. The shock of a fixed-to-variable transition in this environment is significant, and lenders are not always aggressive in offering competitive replacement rates unless you ask.

The Market Is Splitting, Not Crashing

Worth keeping perspective. Dwelling values nationally are still up 9.9% year-on-year, but the pace has slowed and the surface is no longer smooth.

Perth is still running hard. Sydney and Melbourne have cooled noticeably, with auction clearance rates in both cities dipping below 60% in the last fortnight. Regional markets like the Illawarra and Sunshine Coast are holding on to recent gains but seeing fewer transactions.

The implication for buyers is that timing and location matter more than they did six months ago. A blanket "wait and see" call is the wrong response. So is a blanket "buy now". The right move depends on which market you're in and what you can actually borrow.

What to Actually Do This Week

A few practical moves worth making.

Refresh any pre-approvals. If yours is more than 60 days old, the assumption set behind it has changed.

Ask your broker to model serviceability at 4.85%. Westpac is now forecasting two further hikes by August, and while ANZ, CBA and NAB disagree, the downside scenario is worth stress-testing before you commit to a property.

If you're a medical professional, check whether your lender is still offering the no-LMI product you may have qualified for previously. Most major lenders waive LMI for doctors, dentists and select medical specialties up to 90% LVR (and 95% in some cases). These policies have not tightened in line with APRA's recent debt-to-income cap, and they remain one of the strongest serviceability advantages available right now.

If you're refinancing, check the cashback offers. They've thinned out in 2026 but a few major lenders are still running cashbacks of $4,000 to $5,000 on switches above $500,000. That's enough to offset roughly a year of the rate increase.

Key Takeaways

• The cash rate is now 4.35%, with three hikes in 2026 fully reversing the cuts from 2025
• Borrowing capacity for a typical borrower is around $75,000 lower than at the start of the year
• A $736,000 loan now costs around $342 more per month than in January, or $4,100 over a year
• The market is splitting by city and price point, not crashing nationally
• Medical professionals retain access to no-LMI deals up to 90 to 95% LVR, which softens the serviceability squeeze considerably

Get the right structure for this market

Higher rates make loan structure matter more than it did 12 months ago. The wrong product, the wrong split between fixed and variable, or a stale pre-approval can cost you a property or thousands in interest.

Voyage Financial works specifically with medical professionals navigating exactly these conditions. We model serviceability at multiple rate scenarios, identify the no-LMI lender policies still available to your profession, and structure loans for the cash flow reality of medical careers (registrar income, locum work, partnership transitions).
