Australia's central bank has sharply upgraded its near-term inflation outlook, and investors are now betting that interest rates will need to climb a little higher than previously expected.
In its quarterly Statement on Monetary Policy, the Reserve Bank of Australia (RBA) said it now expects headline inflation to rise to 4.5% in the fourth quarter, up from 3.9% in the third. The bank described the inflation outlook as having been “revised materially higher,” citing firmer oil prices and broad-based domestic cost pressures, even as demand cools and unemployment has edged up to 4.7%.
Following the release, financial markets moved to price in a peak cash rate of around 4.85% — implying at least one more 0.25 percentage point hike from the current 4.6% level. The RBA's own forecasts assume that by mid-2027 the cash rate will have been lifted at least once and will stay there through 2028.
Why the RBA changed its view
The key shift in the RBA's thinking is its assessment of how much “spare capacity” exists in the economy. The bank now believes there is less slack than it previously thought, meaning supply is struggling to keep up with demand. When that happens, price growth becomes harder to slow, even if demand is cooling.
Underlying inflation — a smoothed measure that strips out volatile items like food and energy — is now expected to be 3.6% in the fourth quarter, before easing to around 2.9% by the end of next year. That's still above the RBA's 2–3% target band, and the bank's own projections suggest it will take time to get back to the middle of that range.
The RBA also raised its estimate of the non-accelerating inflation rate of unemployment (NAIRU) — the jobless rate below which inflation tends to accelerate — to 4.75%. That's a technical-sounding change, but it carries a clear message: with unemployment currently at 4.7%, the labour market may not be soft enough to justify early rate cuts. In plain terms, the bank is signalling that it may need to see unemployment rise further before it is confident inflation is under control.
What this means for markets
When a central bank raises its near-term inflation forecast and couples it with a “higher-for-longer” rate path, investors typically reprice the shortest-dated interest rates first. That's because 1- to 3-year government bond yields and swap rates mostly reflect where traders think the policy rate is headed over the next few meetings and years.
So the RBA's 4.5% Q4 inflation call makes a 4.85% cash rate harder to dismiss. Short-dated Australian yields are likely to stay elevated, and the Australian dollar could become especially sensitive to upcoming inflation and jobs data that either validates — or challenges — the RBA's view that the economy has less slack than it used to.
For everyday investors, the takeaway is that borrowing costs — from variable home loans to business credit — may stay higher for longer than many had hoped. If you're holding cash or short-dated bonds, higher rates can be a positive, as yields on savings accounts and term deposits tend to rise. But for those with debt, especially mortgages, the prospect of another rate hike adds to the pressure on household budgets.
What to watch next
The RBA's revised forecasts are not set in stone. Inflation and jobs data over the coming months will be crucial in determining whether the bank actually follows through with another hike. If inflation comes in softer than expected, or unemployment rises more sharply, the case for a 4.85% peak could quickly fade.
Investors will also be watching global oil prices, which the RBA cited as a key driver of its higher inflation call. A sustained drop in crude prices could ease some of the pressure, as recent moves in gold and other assets have shown how sensitive markets are to inflation expectations.
The RBA's next policy meeting will be closely scrutinised for any sign that the board is leaning toward another hike. A split vote, as seen in some recent decisions, could signal that the tightening cycle is nearing its end — or that more increases are on the way. For now, the central bank's own forecasts point to rates staying elevated for an extended period, and markets are pricing accordingly.
For investors, the key is to stay informed and avoid making hasty decisions based on a single forecast. The RBA's outlook is just that — an outlook — and it can change quickly as new data arrives. What's clear is that the era of ultra-low rates is firmly in the rear-view mirror, and the path back to normal inflation is proving bumpier than many expected.
