Introduction
Risk Management for Longevity Risk ProductsInvestment
Mortality
Expenses
Long term interest rate, inflation, credit risk
Heterogeneity, systematic risk, reinsurance, hedging
Inflation and productivity
Interest rate risk Lack of longer term government bonds Limited inflation linked securities (infrastructure) Equity and asset swaps or options (downside protection) Lack of liquidity
Longevity Risk and Pooling Heterogeneity Adverse selection Pooling and systematic risk “Unknown/unknown” - wars, pandemics and disease Solvency and credit risk
Longevity Risk and Pooling
–Caution: Normal distribution of lifetime assumed
Dependence significantly reduces risk pooling efficiency
Independence – risk pooling efficient
– Correlation
– No of lives
– Indexed annuity value
–95% confidence age
Inflation risk Volatility and hedging Product design – CPI, full, fixed indexation, minimum, capped Demand and pricing
Role of Private Markets Product innovation Lack of hedging instruments (longevity, inflation, long term interest
rate) Capital and regulatory requirements (Solvency II, risk based) Expense and efficiency Mutual (Industry funds, Government) Shareholder (Retail funds, Insurers)
The Role of Government Private Market Support
Longevity/survivor bonds Inflation linked bonds
Longevity Indices JP Morgan Lifemetrics Deutsche Bourse Xpect indices Australian Government Actuary (population); APRA, ASX (annuitants)
The Role of Government Public provision
Immediate annuities or Deferred annuities Compulsory or optional Full, partial, minimum level Risk rating or community rating
Expense efficiencies Costs of capital and credit risks
Policy Options Private Sector: develops an annuity market with government
support to provide or organise hedging products for the major risks otherwise private sector can’t supply efficiently priced lifetime annuities attractive to retirees.
Public Sector: annuitisation compulsory for compulsory accumulation SGL retirement benefits, purchase price reflect differing longevity risks.
Private/Public Sector partnership: a private/public combination with the private sector providing annuities for fixed terms, such as until age 85 or earlier death and the public sector providing a (compulsory) deferred annuity from age 85 until death.
