Key Highlights

  • Assistant Governor Christopher Kent said the cash-flow channel receives the most attention but is not the most important way rate rises work.
  • He pointed to the wealth, intertemporal and Exchange Rate channels, and said financial conditions are "somewhat restrictive" overall.
  • His remarks, made on 19 October 2026, are one official's views and not a Board decision.

When the Reserve Bank of Australia raises interest rates, most people think first about Mortgage repayments. An RBA Assistant Governor has now argued that this cash-flow effect, while visible, is not the most important way higher rates slow inflation. The remark helps explain how the Board thinks its decisions work.

What was said and when

Christopher Kent, Assistant Governor (Financial Markets), spoke at the Commonwealth Bank's Global Markets Conference in Sydney on 19 October 2026. In a fireside chat with Belinda Allen of the Commonwealth Bank, he said the cash-flow channel receives the most attention but is not the most important. He also pointed to the wealth, intertemporal and exchange rate channels.

These are Kent's views in a public conversation. They are not a new Board decision or a forecast of one.

The other channels

The Wealth channel works through asset prices, including housing. The intertemporal channel encourages people to save rather than spend when returns rise. The exchange rate channel works through the Australian dollar, which can affect the price of imports.

Kent described the exchange rate as a useful stabiliser rather than a hindrance. He noted that higher interest rates and a higher Australian dollar reduce the cost of imported oil, because "Australians don't pay US dollars at the pump". He said models suggest the dollar is marginally above its long-run equilibrium against the real trade-weighted index.

Offset accounts and household buffers

Kent said offset accounts are a deliberate form of household self-insurance. That fits the September minutes, which record that scheduled mortgage payments account for about 10 per cent of household disposable income, around the 2024 peak, and that fewer than 2 per cent of owner-occupier borrowers face a cash-flow shortfall.

The minutes also say savings buffers differ by income. They are just under one year of scheduled repayments for the lowest income quintile and almost two years for the highest.

Is policy restrictive enough?

Kent said financial conditions are "somewhat restrictive" overall, and that the Board's question is "is it restrictive enough?" He said the cash rate path over the next 18 months sits at the upper end of the range of neutral estimates, which he described as highly uncertain. He added that it is "still early days" for transmission, with no evidence that it has changed dramatically.

Housing Credit growth has weakened, he said, while Business credit has grown strongly, partly to fund data centres. Credit spreads and Equity risk premia, he said, suggest conditions are not especially tight.

What it means for readers

The cash rate and individual lenders' mortgage or deposit rates are different things. Lenders decide their own pricing, so Board decisions do not pass through automatically or identically.

For borrowers, the point is that rate rises work through several routes at once, not only through repayments. For investors, the exchange rate and asset-price channels are worth watching.

Uncertainties

Kent cautioned against over-reading volatile monthly labour data, which he said are affected by survey changes. The Unemployment rate rose to 4.7 per cent in the latest labour force data he cited. Neutral rate estimates remain uncertain, and Kent said nobody knows the current neutral rate precisely.

What to watch next

Kent said September-quarter Inflation data were due the week after his remarks and that the Board meeting was just over two weeks away. The Monetary Policy Board meets on 2 and 3 November 2026. Watch the accompanying statement for how the Board describes the restrictiveness of policy.
