Introduction
As of 2023, the bond market has shown remarkable resilience amid fluctuating interest rates and geopolitical tensions. With global bond issuance projected to exceed $20 trillion in 2026, investors are increasingly focusing on bond convexity to assess portfolio risk and returns. Convexity, a measure of the curvature in the relationship between bond prices and interest rates, can significantly affect portfolio performance, especially in an environment of rising rates. Recent studies indicate that portfolios with a high convexity can outperform those with lower convexity by as much as 30% during volatile market conditions.
