Australia’s policy bargain on inflation broke into two speeds this week: the Reserve Bank moved on Tuesday, and the big four banks moved on Friday. Mortgage holders are paying more from today while many household bills that feed the consumer price index are still adjusting with a lag. We should not treat that timing gap as proof the hiking cycle is “working” for families—it is proof that monetary policy hits borrowing costs before it delivers visible relief at the checkout.
The board’s logic
The RBA lifted the cash rate target to 4.60 percent on 29 September, unanimous and explicit that inflation remained too high. Governor Michele Bullock said the decision was difficult for mortgaged households yet necessary to avoid even higher rates later. Markets subsequently trimmed the probability of a November hike after inflation readings, a welcome shift that does nothing for direct debits resetting this morning.
Asymmetric pass-through
Banks passed the full 0.25 percentage points to variable mortgages effective 9 October, lifting headline owner-occupier rates above 6 percent at every major. Deposit rates also rose, but typical savings balances are too small to offset the mortgage shock. The asymmetry is familiar: lending rates reprice quickly; grocery and rent disinflation, if it comes, arrives quarter by quarter in ABS data that households experience as still-expensive lamb chops and insurance renewals.
Politicians who urge banks to “do the right thing” on deposits while supporting RBA tightening should be honest that the primary transmission channel is crushing demand via housing, the asset most Australians already own leveraged.
Who bears the cost
Recent buyers with low equity face the steepest marginal payment increase. Renters are not immune—landlords pass financing costs through with delay, and vacancy rates in several capitals remain tight. Fixed-rate borrowers rolling off two-year terms this spring will discover revert rates near 7 percent, a cliff unrelated to today’s announcement but part of the same cycle.
Lower-income households spend more of their budget on essentials with less flexibility to cut discretionary items. A rate hike that trims restaurant spending for professionals may force tradies to skip car maintenance. Aggregate GDP might slow, but the distribution is regressive unless fiscal offsets arrive.
What government still owes
Treasury has ruled out cash splashes every rate day, rightly fearing inflationary offsets. Targeted relief—energy bill rebates, cheaper medicines via the PBS, rent assistance indexed faster—can cushion without undoing the RBA. The test is whether those programs scale with the mortgage shock now, not whether a press release celebrates one softer CPI print.
Migration and housing supply debates belong in the same conversation: if population growth outpaces completions, rent inflation will frustrate the bank’s work regardless of cash-rate levels.
A November pause is not a victory
Money markets pricing a 20 percent chance of another hike in November is cold comfort to a household whose Westpac variable rate now starts at 6.24 percent on advertised tables. Pausing while keeping rates at 4.60 percent merely stops digging; it does not fill the hole in monthly cash flow.
We need the board to keep inflation credibility. We also need elected leaders to admit that credibility has a human timetable misaligned with quarterly CPI. If the government wants Australians to trust the pain, show them relief on the same calendar banks use—not the calendar of an election-year budget.
Our view
Continue the fight on inflation, but stop pretending Friday’s mortgage repricing and Monday’s grocery shop live in the same policy moment. Until they do, public support for independent monetary policy will erode—and populists offering simplistic migration or rate caps will fill the gap with worse ideas.
