RBA expected to lift cash rate to 4.85% as Australian budget pressures build

The Reserve Bank of Australia is expected to raise rates again on Tuesday, after inflation reached 4.3% to September. The government says December's budget update will not promise net savings.

What happened

The Reserve Bank of Australia is expected to lift the cash rate to 4.85% on Tuesday, a level not seen since 2008 [1]. Inflation was 4.3% to September, which raised expectations of the move at this week's meeting [2]. Millions of households are absorbing higher borrowing costs [1].

Finance Minister Katy Gallagher and Treasurer Jim Chalmers will not promise net savings in December's mid-year fiscal outlook [2]. Budget pressures are growing in health, aged care and borrowing costs [2]. Gallagher pointed to expenditure review decisions that are still pending. She also defended what she called necessary spending on Medicare and veterans [2]. RBA official Sarah Hunter said government spending contributes to demand-driven inflation [2].

Politically, the government faces headwinds from inflation linked to wars, an oil crisis and AI demand [1]. There are also signs of fracturing inside the Labor caucus and process failures [1]. There appear to be tensions between Prime Minister Anthony Albanese and Chalmers over spending restraint ahead of the December update [1]. FinUties' news monitor logged 3 reports on this story from 1 outlet in recent days, and 103 earlier related reports going back to 22 January 2026.

How we got here

The RBA unanimously raised the cash rate by 25 basis points to 4.6 per cent on 29 September [3]. That was the fourth increase of 2026 and the highest level in 15 years [3]. Chalmers attributed higher prices partly to the Iran conflict and an AI investment boom [3]. Governor Michelle Bullock said domestic excess demand and weak productivity were pre-existing drivers, and that the oil shock worsened the outlook [3]. Opposition Leader Angus Taylor blamed federal spending at 26.9 per cent of GDP [3].

By 1 October, attention had turned to the budget update. Annual inflation had risen to 4% at that point, and blame politics was intensifying ahead of December [4]. Albanese was travelling to climate meetings in Fiji/Tuvalu and Turkey while rate pain dominated domestic debate [4].

On 4 October Chalmers signalled that the mid-December update would focus on savings rather than new cost-of-living relief [5]. He cited intensifying global and domestic budget pressure from inflation and rising borrowing costs [5]. He warned that servicing Australia's trillion-dollar debt would cost billions more as bond yields surge, with spillover expected from rate moves in major economies [5]. Opposition figures blamed government spending for inflation and called for him to resign [5].

What has changed since then is that the September-quarter inflation figure of 4.3% is higher than the 4% cited on 1 October [2][4]. A further rate rise to 4.85% is now expected, taking the cash rate above the 4.6% set in September [1][3]. The government's message has also hardened from a savings focus to a refusal to promise net savings [2][5].

The government has been under strain on other fronts. In September, Home Affairs Minister Tony Burke released a migration package that aims for 225,000 net overseas migration by 2027–28 [6]. It drew criticism from both restrictionists and those who see the measures as draconian [6]. In August, remarks by Albanese about crown melons drew criticism from Japan's former ambassador and caused diplomatic tension with a key strategic partner [7]. Neither episode bears directly on rates, but both form part of a picture of political handling under scrutiny.

Why it matters for markets

A move to 4.85% would extend a tightening cycle that has already brought the cash rate to a 15-year high [3][1]. That could keep pressure on households with borrowing costs, as the coverage of the expected move indicates [1].

For public finances, rising borrowing costs are already named as a source of budget pressure [2]. Chalmers has linked higher bond yields to a larger cost of servicing the debt [5]. If the December update does not show net savings, the pressure from borrowing costs on the budget could persist [2][5]. The RBA's comment that government spending adds to demand-driven inflation suggests fiscal choices could also feed into the central bank's assessment [2]. How markets would price these factors is not yet known.

Chalmers has also said that rate moves in major economies are expected to spill over into Australia [5]. Any such channel would depend on developments abroad that are not yet known.

What to watch

• The RBA's decision on Tuesday, and whether the cash rate reaches the expected 4.85% [1].
• Any explanation the RBA gives of how domestic demand, government spending and the oil shock each contribute to inflation [2][3].
• The December mid-year fiscal outlook, including the outcome of pending expenditure review decisions and whether Albanese and Chalmers agree on spending restraint [1][2].
• Whether the pressure on health, aged care and debt-servicing costs grows as bond yields move [2][5].
• Party-room debate over superannuation policy. Liberal backbencher Garth Hamilton claims majority support to abandon early super access for first-home purchases, and Labor is framing the next election as a referendum on super [8].
