Delving deep into demographics to understand long term drivers of equity returns

A structured view of the population shifts that guide long-term market behaviour.

Demographic trends are an important structural influence on equity valuations. Oxford Economics applies demographic ratios, such as the share of middle-aged peak savers relative to younger and older cohorts, to understand how shifts in population structure affect savings behaviour, equity risk premia and long-term market returns.

Investors often find it difficult to separate short-term market noise from deeper structural drivers.

Key issues include:

  • assessing how ageing populations alter demand for financial assets
  • quantifying the effect of demographic change on risk premia
  • integrating domestic and global demographic trends into valuation models
  • aligning long-horizon return expectations with structural trends

Without this, investors risk misjudging valuations or overlooking areas where markets are structurally mispriced.

Oxford Economics provides a transparent demographic and valuation framework that supports long-term asset allocation decisions.

  • modelling the ratio of middle-aged peak savers to young adults and retirees
  • estimating how these shifts affect savings rates and demand for equities
  • analysing global demographic patterns, including China’s ageing profile and emerging market saving behaviour
  • feeding these insights into our CAPE-based valuation models

This enables investors to test assumptions, understand structural pressures on valuations and incorporate demographic forces into both strategic and tactical planning.

Clients gain a clearer view of how demographic change is likely to influence equity risk premia and valuation trends over the coming decade. This allows them to:

  • calibrate long-term return expectations more realistically
  • anticipate where demographic forces may support or weigh on valuations
  • distinguish structural influences from shorter-term market cycles
  • build allocation strategies that account for demographic headwinds and tailwinds
  • avoid mispricing driven by demographic shifts that markets may not yet have reflected

In practice, this insight helps investment teams set more credible return assumptions, strengthen investment-committee discussions and position portfolios for long-run structural change.
