The fixed rate mortgage market is sending a blunt message to Australian borrowers: the era of cheap debt is not just over, it may have further to fall. Commonwealth Bank and Westpac have both lifted their fixed home loan rates in the wake of the Reserve Bank of Australia's decision to raise the official cash rate to 3.85 per cent at its first board meeting of the year, with CBA lifting by 0.25 percentage points and Westpac by 0.30 percentage points.
For CBA, this is the second fixed rate increase in just six weeks. The move brings every fixed rate product the bank offers above six per cent, a threshold that would have seemed extraordinary to most borrowers just three years ago. Westpac's one, two and three-year fixed rates still open with a five, offering marginally more relief, while NAB now holds the title of lowest fixed rates among the big four, according to financial comparison site Canstar.
The broader picture is equally stark. Canstar reports that around 60 lenders have raised at least one fixed rate product since the RBA's February 3 decision. Fixed rates below five per cent have effectively disappeared from the market. The cheapest available fixed rate now sits at 5.18 per cent for a two-year term, offered by BankVic.
Canstar data insights director Sally Tindall put it plainly, as reported by 9News: "This latest round of fixed rate increases from Australia's two biggest banks are in response to elevated fixed rate funding costs, but also an expectation this is not the end of the cash rate hikes." She added that weak customer demand for fixed rate products, and competition among lenders, had also shaped the decision. Tindall expects the trend to continue if the RBA proceeds with further hikes across 2026.
That scenario looks increasingly plausible. Higher-than-expected inflation data released after the RBA's latest meeting has added weight to forecasts of a follow-up hike as early as May. The RBA is scheduled to meet again in March and in May, the latter falling before the government hands down its 2026 federal budget.
From a fiscal management perspective, the RBA's tightening cycle reflects a legitimate effort to restrain inflation without resorting to blunter instruments. Critics of the central bank's pace, however, argue that rapid successive hikes risk tipping household consumption into a sharper contraction than the data warrants. Mortgage stress is a real and spreading phenomenon: one in six Australian households is already struggling to pay power bills, and rising debt-servicing costs compound that pressure month by month. The Fair Work Commission's minimum wage decisions and broader wage growth data will be key inputs into how much buffer lower-income borrowers actually have.
There is also a structural question about fixed versus variable rates that the current environment throws into relief. When fixed rates were at record lows, the appeal of locking in was obvious. Today, with fixed rates above six per cent and the cash rate cycle potentially nearing its peak, borrowers face a genuine dilemma: pay a premium now to fix costs for certainty, or stay variable and bet on rate cuts later. Neither path is without risk, and the Australian Bureau of Statistics housing finance data suggests most borrowers are choosing variable, given the near-anaemic take-up of fixed products Tindall described.
What the market hasn't fully priced in yet is the downstream effect on property values if two or three further hikes materialise. Falling borrowing capacity directly constrains what buyers can offer, and that dynamic is already visible in auction clearance rates across major capitals. For investors watching bank margins and mortgage book quality, the signal from CBA and Westpac this week is worth taking seriously. The banks are not raising fixed rates to be punitive; they are responding to their own funding costs and their own read of where the RBA is headed. That read, right now, points upward.
Reasonable people disagree about how much further rates need to rise to bring inflation sustainably back to target. The RBA has been transparent about its data-dependent approach, and the incoming budget will add another variable to an already complex equation. For borrowers, the practical takeaway is straightforward: the assumption that rate relief is imminent looks increasingly difficult to sustain, and financial planning built around that assumption deserves a second look.
