We know that the US and Australian economies are very similar in that economic activity is dominated by private consumption (>60%). However, when monetary policy needs to shift private demand up/down, there is a major difference between Australia and the US.
Households in Australia largely borrow for housing through variable mortgage rates, whereas in the United States, they borrow with reference to the 10-year fixed rate (and can readily refinance as these rates lower, and remain unchanged when they rise). The implications for monetary policy are quite stark:
In Australia, increases in the cash rate have a fairly immediate transmission to variable rate mortgages, albeit, with some lags as consumers adapt to the scale of the impact on their cash flow. Importantly, it impacts all households with variable rates plus the next marginal activity for households, be it a new mortgage or new car finance, and for businesses through their reference rate
In the United States, increases in the Fed Funds Rate have a more muted effect on existing borrowers who are largely tied to existing fixed rate mortgages. The impacts, therefore, are largely on the marginal next household borrower – either the next house finance or car finance, as well as business borrowers, who are subject to shorter-term finance
