The Future of Decumulation – why retirement planning needs a new approach

For decades, the retirement industry has focused on portfolio construction, product innovation and distribution to help grow the pot as much as possible for future retirees. But that post-retirement phase needs something entirely different.

Key takeaways:

  • Decumulation is fundamentally different from accumulation. Retirement success is no longer about maximising portfolio value, but sustainably funding income, flexibility and spending needs over an uncertain lifetime.
  • No single retirement product can solve every challenge. Effective decumulation requires balancing competing objectives such as income, growth, liquidity, longevity protection and personal circumstances as they evolve.
  • The future lies in personalised, system-based retirement solutions. AI, governance, advice and modular investment components can work together to deliver scalable, individualised retirement outcomes.

For decades, pension strategies have been built around portfolio construction, product innovation and distribution, all focused on growing the retirement pot as much as possible. The more complex phase begins at retirement, when accumulated assets must be converted into sustainable, resilient and personalised income.

Retirement is not a single risk. It is a changing set of trade-offs between spending today, preserving flexibility, protecting against adverse markets, maintaining purchasing power and ensuring income that lasts for life. Yet decumulation is still often treated as accumulation with lower risk and withdrawals attached. In this paper, Matthew Bullock, Head of Portfolio Construction & Strategy, and Ian Warford, Executive Director, Head of Solutions, Client Group UK, consider how the next generation of decumulation solutions can help translate each person’s objectives, constraints and tolerances into a personalised mix of income, liquidity, growth and protection components.
