Quantitative Tightening with Slow-Moving Capital
NBER
2024.08.01
We document shifts in investor composition during quantitative tightening, which suggest that investors adjust their portfolios at different speeds. To understand its implications for bond valuation, we develop a general equilibrium model which highlights the dynamic interaction between heterogeneous investors. In the model, long-term investors have higher risk-taking capacity, but face a portfolio adjustment cost; liquidity traders have lower risk-taking capacity, but can trade freely. Our model predicts a novel overshooting pattern: when the central bank unwinds its bond purchase, slow adjustment by long-term investors requires liquidity traders to absorb the imbalance, who demand a higher risk premium that creates excessive bond price decline and volatility in the short run. As a result, quantitative tightening is not simply a symmetric reversal of quantitative easing.
