Australia: Monthly CPI proving “sticky”

Australian monthly CPI fell to 4.9% for the 12 months to October while trimmed mean — the RBA’s favorite measure of underlying inflation — edged down slightly, from 5.4% in September to 5.3% in October. This supports the RBA governor’s message that services inflation may prove difficult to tame.

Especially when one considers that electricity prices are measured net of government rebates and relief payments. Before adjustment, electricity prices increased by 14.0% over the past 12 months and not the 10.1% included in CPI.

Monthly rent inflation also shows a surprising fall from 7.6% for the 12 months to September — to 6.6% in October. The decline of 1.0% was again due to adjustment for Commonwealth Rent Assistance payments.

In monthly terms, Rent prices fell 0.4% in October, following a 0.3% rise in September. The fall in Rents this month was due to the remaining impact of the changes to Commonwealth Rent Assistance. From 20 September the maximum rate available for rent assistance increased by 15%, on top of the regular biannual indexation. An increase in rent assistance reduces rents for eligible tenants. Excluding the changes to rent assistance, Rents would have risen 0.7% over the month. (ABS)

Conclusion

CPI inflation is understated by adjustment for Government rebates and assistance payments. Trimmed mean CPI is proving “sticky” and may require further rate hikes from the RBA.
