ING Australia has increased fixed mortgage rates for owner-occupiers and investors by 20 basis points, a move effective for loans settling from Wednesday. The adjustment comes just 13 days before the Reserve Bank of Australia (RBA) is set to announce its next cash rate decision, currently at 4.35%.
This repricing, reported by Nine on September 16, affects all of ING's fixed-rate home loan products, while variable-rate offerings remain unchanged. The timing of this change is significant: ING is charging more today to lock in certainty over the next one to five years, ahead of the RBA's September 29 meeting.
Market Context and Funding Conditions
The move provides insight into market funding conditions, as the RBA remains uncommitted on its next step. Fixed mortgage rates are influenced by term funding costs, hedging expenses, expected policy rates, and competitive dynamics. The cash rate, which the RBA targets, remains at 4.35% since August 12, with the next update scheduled for 2:30 p.m. AEST on September 29.
Rate Hike Expectations Intensify
ING's repricing follows a shift by Citi to a more aggressive outlook, now expecting two 25-basis-point hikes this year, bringing the terminal cash rate to 4.85%, up from its previous 4.60% forecast. Citi also pushed its first expected cut to the fourth quarter of 2027. Reuters reported on September 11 that swaps implied 33 basis points of tightening by November and 40 by December, with a 90% probability of a September increase.
The Australian dollar was little changed near US$0.7135, while the S&P/ASX 200 closed 0.61% lower at 8,696.5. These prices indicate that much of the higher-rate risk was already priced in before ING's announcement, suggesting investors should not view this as a fresh policy shock.
Impact on Borrowers
For borrowers, a 20-basis-point increase is material. On a A$500,000 principal-and-interest mortgage with 25 years remaining, the rate rise from 6.00% to 6.20% increases monthly payments by about A$61, from A$3,222 to A$3,283. This calculation, based on standard monthly amortisation and excluding fees, illustrates the potential impact. ING's fixed-loan terms allow one- to five-year fixes and a rate lock for up to 90 days for a fee, so the actual effect depends on term, loan-to-value ratio, and settlement timing.
Why the RBA Could Still Wait
The case for another increase is straightforward. Deputy governor Andrew Hauser said on September 8 that inflation was too high and the board was assessing whether three increases at the start of 2026 had done enough. He identified three upside risks: the Middle East conflict, an AI-driven global investment boom, and weak Australian supply capacity. The full interview also recorded stronger-than-expected recent inflation and growth readings.
However, the counterargument lies in the same RBA evidence. Hauser cited falling house prices and weak consumer confidence, and said the board was moving slowly to preserve employment gains. The central bank's August policy outlook forecast subdued growth and unemployment rising gradually to 4.8% by the end of 2028, with trimmed-mean inflation easing from 3.6% in June 2026 to 2.4% by June 2028. A sharper housing slowdown or weaker consumption could give the board reason to pause even if wholesale markets have repriced.
Competitive Dynamics and Market Signals
There is also a competitive limit to what one lender can reveal. ING may be protecting its margin against higher term funding costs or reducing demand for fixed loans at an unattractive price. Other banks could follow, but they could also absorb some funding pressure to win customers. The signal becomes stronger if repricing spreads across lenders and Australian short-dated yields continue to rise; it weakens if wholesale yields retreat while rivals leave fixed offers unchanged.
For equity and currency investors, September 29 is only the first checkpoint. A single quarter-point increase would take the cash rate to 4.60%, still one move below Citi's 4.85% peak. The more consequential question is whether the RBA's language keeps a second 2026 increase in play. That guidance will affect the Australian dollar, the yield curve, and bank funding assumptions more than Wednesday's 20-basis-point mortgage change on its own.
