CBA sees ageing cutting G20 annual GDP per capita growth by 0.16 percentage points through 2050
SPY•SPY•SPY•SPY•Commonwealth Bank estimates ageing could reduce annual G20 GDP per capita growth by around 0.16 percentage points from 2025 to 2050. It says productivity, including AI adoption, could offset some pressure, while age-related deficit spending could put upward pressure on the neutral interest rate.
Commonwealth Bank estimates ageing could cut G20 GDP per capita growth by around 0.16 percentage points annually between 2025 and 2050. Australia is among five high-income G20 countries whose working-age populations are projected to expand through 2050; the bank says AI adoption could lift Australian labor efficiency by around 2 percentage points over five years.
The bank says productivity is the main long-term offset to demographic pressures. It also says age-related spending financed through persistent deficits could increase government borrowing and put upward pressure on the neutral interest rate.
