News about growth, inflation and monetary policy influences bond and equity markets. For bonds, the relationship is straightforward but for equities, the relationship is more complex. Therefore, the correlation between bond prices and equity prices fluctuates over time. Since 2000 it has been predominantly negative, thereby creating a diversification effect. It underpins the demand for bonds, even when yields are very low. Unsurprisingly, during the recent Federal Reserve tightening cycle, the correlation has turned positive again. Based on past experience, one would expect that, as the Federal Reserve starts cutting rates later this year, the bond-equity correlation would turn negative again.
