Investment universe

Historical risk and return informed the asset selection.

The broader opportunity set includes global and emerging-market equities, listed property and infrastructure, euro bonds, inflation-linked exposure and gold. The recommended portfolio selects five complementary building blocks rather than simply choosing the assets with the highest historical returns.

Historical annual return and volatility for the broader investment universe considered in the portfolio analysis.
Glide path allocation

The allocation becomes more conservative over time.

Equity exposure falls from 50% to 30% between ages 45 and 68. Bond exposure rises from 40% to 60%, while gold remains at 10% throughout.

Stress testing

Persistently weak real returns present the greatest funding risk.

Under the stagflation scenario—6% equity returns, 2% bond returns, 5% gold returns and an additional annual drag—the median retirement value falls to approximately €570,000.

Stagflation

The median outcome falls below the capital target, showing the impact of prolonged low real returns.

Sequence risk

A major drawdown close to retirement can materially reduce the capital available when withdrawals begin.

Longevity risk

A longer retirement period increases the total withdrawals required from the portfolio.

Policy risk

Changes to pension benefits, healthcare costs or investment taxation can affect the funding requirement.
