The CommBank Household Spending Intentions (HSI) Index rose by 0.8 per cent in August to 115.5, highlighting the momentum in the Australian economy, higher inflation pressures and the impact of the RBA’s monetary policy tightening.

The index – which combines Commonwealth Bank of Australia (CBA) payments data and Google Trends search information – saw increases in the categories on health and fitness, home buying, motor vehicles and household services. 

A strong rise in motor vehicles spending by 13.3 per cent this month indicates some easing in international supply chain constraints that have been dominating the sector, with ordered vehicles being delivered in greater numbers.

Health and fitness spending rose 7.2 per cent this month and 4.6 per cent compared to August 2021, focussed on spending for medical services, doctors and hospitals, due in part to an increase in non-essential operations which has been delayed during Covid.

In contrast, there was a weakness in discretionary spending in sectors like travel, entertainment, transport and retail.  Travel dropped 3.9 per cent in August, but is 141.2 per cent higher compared to August 2021 when Covid restrictions were widespread across much of eastern Australia. Entertainment spending similarly declined by 7.2 per cent following gains in July when movie theatres, restaurants and spending on food were all higher.

CommBank Chief Economist Stephen Halmarick said that interest rate increases and inflationary pressures are beginning to take effect on household spending.

“The HSI’s annual rate has now increased 15.1 per cent, reflecting the weakness in August last year during the ‘Delta lockdowns,’ when Covid-related restrictions were in place across New South Wales and Victoria.

“While the index rose in August, we’re seeing weakness in discretionary spending following recent interest rate increases and a growing move to value purchasing. For instance while grocery spending remains high, we’re hearing customers are swapping to value products in response to higher food prices.

“Spending for household services has also risen 4 per cent in August, with charitable donations leading the category, likely signalling a stressful environment for many in the community.”

Following last week’s fifth consecutive monthly increase in interest rates by the Reserve Bank of Australia, CBA’s Economics team is forecasting 25bp interest rate increases in October and November, taking the cash rate to 2.85 per cent, before the RBA looks to cut rates in H2 2023.
