The Reserve Bank lifted the cash rate by 25 basis points to 4.35 per cent on Tuesday, the third consecutive 2026 hike. Governor Michele Bullock, in the post-meeting press conference, used the phrase "back to square one" to describe how an inflation impulse imported from Middle East fuel costs had undone the rate cuts the board delivered in late 2025. The market read the language immediately. Three-year Australian government bond yields rose 18 basis points within an hour of the decision. The interest-rate futures curve now implies a peak cash rate of about 4.75 per cent before year-end, with at least one further 25-basis-point hike priced in by August.
Three things in the accompanying statement matter for borrowers. First, the board explicitly named "second-round effects on prices for goods and services more broadly" as the reason for the move. That language signals the board sees the inflation impulse as embedding rather than passing through. Second, "further tightening" is back on the table, language that had been removed from earlier statements this year. Third, the unemployment forecast was revised down (lower unemployment is read as inflationary) which gives the board cover to keep moving.
What does the hike cost a typical borrower?
Most major lenders announced full pass-through of the 25-basis-point hike within 24 hours of the decision. The dollar impact varies by loan size. On a $600,000 25-year owner-occupier loan, the May hike alone adds about $91 to the minimum monthly repayment. On a $700,000 loan the add-on is about $107, on $800,000 about $122, and on $1,000,000 about $153. Those figures are the third such add-on this year. For an average new-loan borrower at the start of 2026, monthly repayments are now $272 to $295 higher than they were in January, depending on loan size. That is roughly $3,300 to $3,540 a year of extra interest, after tax, on the typical mortgage.
Roy Morgan's March 2026 mortgage stress data put 26.8 per cent of mortgage holders at risk of stress. That was before the May hike. The same dataset historically shows a 1 to 2 percentage-point increase in the at-risk cohort for each 25-basis-point hike, which would push the figure into territory not seen since 2008.
The cash rate is now where it was in late 2024. The lived experience for borrowers is not the same: many are now into year three of elevated repayments with thinner buffers than they had in 2024.
How does this change the fixed-versus-variable decision?
Two-year and three-year fixed rates moved up between 0.30 and 0.55 per cent in the 48 hours either side of the decision, broadly tracking the move in wholesale funding. The fixed-rate market is no longer pricing imminent cuts. For a borrower making the fix-or-float decision today, the calculus is different to the one we wrote about last quarter.
For a household on a tight servicing buffer, where another 0.50 per cent of variable-rate increase would push monthly cashflow into the red, the case for fixing for two years is now stronger than it has been since 2023. The premium you pay for that certainty is, on most lender panels, between 0.20 and 0.40 per cent above the lowest available variable rate. That premium is the price of removing one large source of household stress.
For a household with a healthy buffer, the maths still favours variable. Variable products typically include 100 per cent offset, unlimited extra repayments, and full redraw, all of which compound in your favour over the life of the loan. The main risk is that you spend the optionality of variable on lifestyle rather than principal reduction. If you are not making extra repayments or building offset, a fix is psychologically a forcing function.
What about the fixed-rate cliff?
A meaningful cohort of 2021 and early-2022 fixed loans is rolling onto variable in 2026. For a borrower whose loan was fixed at 1.99 per cent and now reverts to a variable rate near 6.50 per cent, the increase on a $600,000 loan is roughly $1,200 to $1,400 a month. That is not a forecast; it is the actual repayment shift on the day the fixed term ends. The May hike adds another $91 a month on top of that. Refinance shopping is no longer optional for this cohort.
What we will be watching
The June meeting is the next data point. The May labour-force data lands the Thursday before; if unemployment falls and wages stay strong, the case for a June hike strengthens. Bond market pricing currently implies roughly even odds of a June move, with another hike fully priced by August. The Bank's August Statement on Monetary Policy will be the next significant set-piece for forward guidance.
For now the read-through is plain. The path of policy from here is up before it is down, the magnitude is uncertain, and the cost of certainty has gone up with it. Anyone who can refinance to a competitive rate, do so. Anyone who is stretched, talk to your lender about hardship arrangements before you miss a payment. Anyone shopping for fixed, ask about break fees in writing.
