Public final demand is now 28.9% of GDP, basically back at pandemic levels and around 4 percentage points above its pre-COVID share. I think that increase in expenditure, roughly $120 billion a year at today’s GDP, is what people are concerned about.
But it’s a slightly funny category. A lot of it is government purchasing services on behalf of households, including aged care, disability and childcare. So this isn’t necessarily conventional fiscal stimulus, but it is a substantial shift towards publicly financed demand.
The 450bp increase in the policy rate isn’t really relevant to explaining public final demand. Its level is overwhelmingly a fiscal policy choice.
