Assistant Governor (Economic) Hunter spoke at the AFR banking summit about how monetary policy can be both forward looking and data dependent given decisions are always made under uncertainty. The bank looks at the signal from data excluding the noise and uses that in determining its outlook which is then analysed under various scenarios and judgement. In February, the focus was on the impact of US policy and scenario analysis was an important part of this assessment.
- “The links between data, forecast and policy sit at the heart of us saying that policy is ‘data dependent’.”
- Hunter said that during times of “heightened uncertainty”, there is more weight put on “real time data” relative to forecasts.
- Hunter noted that it takes 9 to 12 months for a rate cut to have its maximum effect on GDP growth with the response from dwelling investment particularly timely. Inflation takes longer though at around 18 to 24 months due to the stickiness of prices and the indirect effects from a change in monetary policy on employment and wages.
- The RBA’s model also shows that trade responds “relatively quickly” through the exchange rate channel.
- However, consumers’ reaction is “initially small but grows over time” according to RBA modelling. There is some offset from lower debt payments by less interest income and households tend to smooth their spending.
- The RBA believed that Q4 consumption data showed an underlying pickup relative to Q3 with items not impacted by discounting, such as eating out, showing stronger growth as incomes rose. Its business liaison responses were consistent with this.
