RBA Hikes Cash Rate to 4.35% in Hawkish 8-1 Vote: What ASX Investors Need to Watch Next

The Reserve Bank of Australia raised the cash rate by 25 basis points to 4.35% on Tuesday, the third consecutive hike of 2026 and a level not seen since late 2023. The decision was widely expected, but the vote was not. Eight of the nine board members backed the hike, with only one voting to hold. That is a much sharper hawkish shift from the 5-4 split in March, and it tells investors the board has lost patience with sticky inflation. Governor Michele Bullock also flagged that headline inflation is now expected to peak at 4.8% in June, well above the RBA’s 2-3% target. For ASX investors, the question is no longer whether rates have peaked, but whether Westpac’s call for a further hike to 4.85% by August is now the base case.

What are the Best ASX Stocks to invest in right now?

Why the 8-1 Vote Matters More Than the Hike Itself

The size of Tuesday’s vote is the real story. A 5-4 split in March suggested the RBA could pause if inflation softened. An 8-1 vote in May suggests the opposite. Most board members now believe more tightening may be needed if inflation does not cool quickly. The updated Statement on Monetary Policy lifted both headline and underlying inflation forecasts, citing higher fuel prices and supply pressures from the Middle East conflict.

For investors, this changes the playbook. The market had been positioning for one more hike at most. With the board’s hawks clearly in control, the chance of a fourth hike before year-end has risen sharply. Westpac is the only Big Four bank still forecasting a peak above 4.35%, but its 4.85% target now looks far more credible than it did a week ago.

ASX Bank Stocks Are the Cleanest Trade From Here

Higher rates usually benefit Australia’s Big Four banks because lending rates reprice faster than deposit rates. We believe Commonwealth Bank (ASX: CBA) is the strongest play. Its dominant deposit franchise gives it the best leverage in a hiking cycle, and its A$403bn home loan book benefits directly from the repricing.

National Australia Bank (ASX: NAB) is the next best placed thanks to its business banking exposure, which reprices faster than retail. Westpac (ASX: WBC) released its half-year results yesterday; while it posted a solid A$3.4bn profit, the market remains cautious about margin pressure in the second half. ANZ (ASX: ANZ) tends to lag in hike cycles because its institutional book is more rate-neutral.

What to Watch Next: REITs, Tech, and the Path to 4.85%

The pain falls hardest on rate-sensitive growth and property names. Goodman Group (ASX: GMG), Scentre Group (ASX: SCG), and Charter Hall (ASX: CHC) all face higher debt costs and lower asset valuations as discount rates climb. High-multiple tech names like Xero (ASX: XRO) and WiseTech Global (ASX: WTC) also look exposed, as their valuations rely on future earnings that appear less attractive at higher rates.

That said, much of the bad news may already be priced in. The real risk is not Tuesday’s hike but the path to 4.85% if Westpac is right. Our view is that investors should not trade on Tuesday’s announcement; they should position for the trajectory. If the cash rate climbs further, defensive dividend payers like the major banks, utilities, and gold producers should outperform rate-sensitive growth names for several quarters. The 8-1 vote tells us the path just became much more likely.
