Commonwealth Bank and Westpac lifted a suite of savings and term-deposit reference rates by 0.25 percentage points on Friday, matching the Reserve Bank’s 29 September cash-rate increase to 4.60 percent as mortgage repricing hit household budgets the same morning. The moves give depositors a modest income boost but leave most variable borrowers paying more than they earn on cash, widening the gap between savers and mortgagors in the post-hike cycle.
What changed for savers
CBA said its NetBank Saver and GoalSaver headline rates would rise by the full 25 basis points, effective 9 October, alongside selected term-deposit specials marketed to retail customers. Westpac followed with parallel increases on its Life and Reward Saver products and on several fixed-term deposit tenors, according to rate sheets published overnight. Neither bank framed the lift as a marketing campaign; both described it as a pass-through of the board’s decision, mirroring language used when the cash rate was cut in earlier cycles.
ANZ and National Australia Bank had already announced deposit adjustments earlier in the week as part of bundled lending-and-deposit updates. Together, the majors control the bulk of household deposits, meaning Friday’s repricing resets the reference point for millions of accounts that had been anchored near 4.35 percent funding costs since mid-year.
Why timing matters
Friday’s calendar collision—higher mortgage bills and higher deposit income landing on the same direct-debit day—matters for households running offset accounts. A customer with a $600,000 variable loan and $80,000 in savings sees the mortgage interest charge rise by roughly $125 a month while savings income might climb by less than $20, depending on bonus-tier rules and tax. Lachlan Grant, who covers consumer banking for InfoHandle, said branch staff in Sydney and Melbourne reported heavier call volumes from customers asking whether to shift cash into term deposits before advertised specials expire.
The Reserve Bank’s statement accompanying the hike stressed that earlier increases were tightening financial conditions but inflation remained above target. Governor Michele Bullock told reporters the board understood the pain for borrowers yet believed delaying action would force even higher rates later. Deposit pass-through is the flip side of that calculus: banks fund part of their lending books from domestic savings, and regulators expect some of the cash-rate move to reach depositors even when net interest margins are under pressure.
Small business and term deposits
Business customers with separate operating accounts saw smaller advertised moves on at-call products, while 12-month term-deposit rates at CBA and Westpac now sit above 4.5 percent on headline tables for balances above $50,000. Treasurers at regional councils and not-for-profits said they were rolling maturing deposits into shorter tenors, betting money markets will price a lower chance of a November hike after softer-than-feared inflation prints.
Macquarie Bank, which competes aggressively on savings, had already lifted variable mortgage rates in line with the RBA; its deposit table updates on Friday were watched as a bellwether for non-major pricing. Customer-owned banks and mutuals typically trail the big four by a few days, giving switchers a narrow window to compare bonus conditions before November board meetings.
Competitive dynamics
Analysts at the major brokers noted that funding costs for deposits rose faster than mortgage repricing in some prior cycles, squeezing net interest margins. This time, wholesale markets are also watching oil prices above $US100 a barrel and a softer US technology sector, factors that influenced ASX bank equities even as retail rates moved. CBA shares slipped in early trade while Westpac held flat, suggesting investors weighed deposit beta against credit quality in a slowing economy.
For retirees living off term deposits, the hike is unambiguously positive if institutions maintain pass-through discipline. For young families with thin savings buffers, the deposit lift is symbolic. The Productivity Commission’s recurring theme—that Australians concentrate wealth in housing—means rate cycles transmit mainly through mortgages, with deposit income a secondary channel.
What to check on your statement
Customers should verify whether bonus interest tiers still require monthly deposits or card spend; a higher headline rate can still be forfeited if conditions are missed. Offset accounts linked to variable loans may not earn separate interest but reduce principal charged at the new, higher mortgage rate—often the better deal for indebted households.
Westpac and CBA both publish PDF rate bulletins with effective dates; if your account type is not listed, call before assuming a pass-through. Fixed-rate borrowers are unaffected until expiry, when revert rates will reflect the elevated cash backdrop.
Looking ahead
Money markets now assign a roughly one-in-five chance to another hike at the November board meeting, down from near-even odds before recent inflation data. If the board pauses, deposit specials could fade while mortgage rates stay elevated until competition forces cuts. Until then, Friday’s synchronized reset is the clearest signal yet that the 4.60 percent era is not a blip—it is the baseline from which both savers and borrowers must plan the summer household budget.
