Moody's warns demographic shifts will strain government budgets starting in 2029

Policymakers enact comprehensive fiscal reforms—raising retirement ages, adjusting benefit formulas, broadening tax bases, or boosting immigration—that materially reduce the projected budget strain, which would likely ease long-term sovereign credit concerns and reduce volatility in government bond markets.

Governments acknowledge the challenge but implement only incremental or partial reforms, allowing the structural fiscal headwind to persist; this would plausibly keep downward pressure on long-duration government bonds and favor inflation-hedging assets as central banks face pressure to monetize growing deficits.

Budget pressures force sharp austerity measures, debt restructuring, or credit downgrades in affected sovereigns, which could trigger a repricing of risk across government debt markets and potentially spill into equities and currencies of heavily indebted developed economies.
