The Reserve Bank of Australia has nudged its cash rate up 25 basis points to 3.85 per cent, its first tightening move since late 2023. The increase was widely telegraphed. Its significance lies elsewhere.

For much of the past year, investors had grown comfortable with the idea that Australian monetary policy was on hold, edging eventually towards easing. That narrative has now been disrupted. By acting, the RBA has signalled that inflation, though off its highs, remains too sticky for complacency.

Services inflation, housing-related costs and wages have proved more resilient than policymakers would like. Headline numbers have softened, but underlying pressures are not receding quickly enough to guarantee a smooth return to the 2–3 per cent target band.

Doing nothing risked sending the wrong message about tolerance for drift in expectations. A small hike carries symbolic heft.

Forex markets rethink on the AUD

Markets have taken the hint. Short-end government bond yields have risen as the risk-free rate resets. Interest rate futures now price in a non-trivial chance of further tightening should inflation data disappoint into March and beyond. The era of confidently pencilling in rate cuts has, for now, been shelved.

For fixed income investors, that repricing restores something absent for years: income. Cash and short-dated paper once again offer yields that compete with risk assets. The yield curve has steepened in parts as investors reassess the policy path. If the RBA is serious about “higher for longer”, the front end must reflect it.

Australian equities are less sanguine. Higher cash rates feed directly into higher discount rates. That matters most for companies whose valuations rest on earnings far in the future, growth stocks and leveraged plays in particular. Businesses with strong near-term cash flow, pricing power and sturdy balance sheets should prove more resilient. Differentiation, long muted by abundant liquidity, is back in vogue.

Credit markets face a subtler test. Higher funding costs squeeze borrowers, from households rolling off fixed-rate mortgages to corporates eyeing refinancing walls. The RBA’s move will feed through gradually, tightening financial conditions and tempering demand. But spreads will hinge less on the absolute level of rates than on earnings durability and balance-sheet discipline. In a world of positive real yields, investors can afford to be choosy.

Reserve Bank is being cagey on forward guidance

Housing sits at the fulcrum. Mortgage repayments have already ticked up, eroding disposable income and cooling discretionary spending. Property markets, highly sensitive to borrowing costs, are likely to feel the effect with a lag. A gentle slowdown is precisely the RBA’s intent: restrain demand without triggering a sharper contraction. Whether that balance can be struck remains the central question.

Notably, the RBA has been explicit about its future intentions. Flexibility is the watchword. Each inflation print, labour market release and retail sales update will carry heightened significance. Volatility around data days is unlikely to fade soon.

“The RBA has deliberately avoided providing explicit forward guidance, reinforcing its emphasis on flexibility and responsiveness to incoming data,” observed Barclay Pearce Capital, the Australian wealth management outfit. “Future decisions will hinge on whether inflation continues to moderate and whether tighter financial conditions are sufficient to cool demand without materially weakening economic activity.”

The broader lesson is straightforward. Policy is not on autopilot. Markets that had begun to price a one-way journey towards easing must now confront the possibility that rates remain elevated for longer than assumed. For investors, that shifts the emphasis back to fundamentals: cash flow over conjecture, balance-sheet strength over leverage, valuation discipline over momentum.

Higher rates create headwinds. They also restore gravity, and income. Australia’s central bank has reminded markets who sets the price of money. The adjustment may be uncomfortable. It is also overdue.
