Chart of the Week: C + I + G + (X-M) = GDP

Published on 23 September 2024

Another way of measuring GDP is by combining the expenditure of the final users of the economy. And the June quarter, the expenditure measure of GDP offered a slightly more encouraging view of the Kiwi economy.

Another way of calculating Gross Domestic Product is by the expenditure approach which combines household consumption (C), business investment (I), government spending (G), and net exports (exports (X) minus imports (M)). And the expenditure measure offered a more encouraging view of the Kiwi economy – but only by a smidgen. Expenditure GDP was flat over the June quarter. Household spending, government spending and business investment were all up over the quarter. But the gains made across these three components were offset by the 0.8% decline in exports. And leading the decline was the 4.4% fall in goods exports. The 1.4% decline in agri production was mirrored by falls in exports of dairy and forestry products.

Components of expenditure GDP - June 2024 quarter

Household consumption increased 0.4% over the quarter, far stronger than the 2.2% decline the RBNZ had pencilled in. Despite the June quarter jump, private consumption remains weak with the March quarter print significantly downgraded from 1.6% to 0.5%. Mirroring the decline in retail trade on the production side, consumption of durable goods declined a chunky 3.4% over the quarter. And compared to last year, durable spend is down almost 10%! – the fourth straight annual decline. Households are reining in their big-ticket spending as tight financial conditions weigh on wallets. And the rotation away from goods and towards services continues. Consumption on services increased, albeit by a smaller magnitude compared to the start of the year, up 0.8%.

Annual services consumption increased 1.3% - the first positive print since September 2022, but still running well below the long-term average.

Beyond households, business investment picked up with a 1.1% over the quarter. Investment in plant and machinery lifted almost 2%. Similarly, the downtrend in building consents has seen a 5.8% decline in residential buildings compared to a year ago. Nonetheless, overall gross fixed capital formation eked out a 0.2% gain over the quarter – the first increase after four quarters in decline.
