Liability-Driven Investing: Matching Assets to Obligations

# Liability-Driven Investing Liability-Driven Investing (LDI) is an investment strategy that focuses on matching the duration and cash flows of a pension fund's assets with its future liabilities. ## Why LDI Matters Traditional asset-only approaches focus solely on maximizing returns. LDI takes a different approach by first understanding the nature of pension obligations and then constructing a portfolio that can reliably meet those obligations. ## Key Components ### Duration Matching By matching the duration of assets to liabilities, pension funds can reduce interest rate risk—one of the largest risks facing defined benefit plans. ### Cash Flow Matching For near-term obligations, cash flow matching ensures that specific assets mature at the same time payments are due. ### Surplus Optimization Once the liability-matching portfolio is established, any surplus can be invested more aggressively to improve funded status.
