Pension Fund Management: Asset Allocation, Liability Matching, and Governance

Abstract

Pension funds—the largest pool of institutional investment capital globally, with OECD pension fund assets exceeding $56 trillion—face a distinctive investment challenge: generating sufficient returns to meet long-dated, fixed or semi-fixed future payment obligations (defined benefit pension commitments) while managing the surplus risk between assets and liabilities. The shift from defined benefit (DB) plans, where employers bear investment risk and promise specific retirement income, to defined contribution (DC) plans, where employees bear investment risk and accumulate individual account balances, has been the most significant structural change in retirement finance over the past three decades. DB pension funds employ liability-driven investment (LDI) strategies—matching the duration and cash flow characteristics of their asset portfolios to their pension liabilities—to reduce funding ratio volatility. This paper reviews pension fund asset allocation frameworks, liability-driven investment, the defined benefit funding crisis, and the governance challenges of managing these complex long-horizon institutional investment vehicles.
