Definition
Quantitative tightening is a monetary policy in which a central bank reduces the size of its balance sheet by allowing bond holdings to mature without reinvestment or by selling bonds outright, reversing the bond purchases conducted during quantitative easing.
Why it matters
Quantitative tightening is the reverse of quantitative easing — the central bank shrinks rather than expands its bond holdings. The effect on financial conditions is meant to be the reverse as well, with longer-maturity yields rising or rising more than they otherwise would.
How it works
Quantitative tightening is conducted either passively, by letting maturing bonds roll off the balance sheet without reinvesting the proceeds in new bonds, or actively, by selling securities outright. The Federal Reserve has primarily used passive runoff to reduce the size of its balance sheet, capping the pace of runoff at fixed monthly amounts. The mechanical effects are the reverse of quantitative easing: bank reserves contract as the maturing securities reduce the Fed's liabilities, longer-maturity bond supply available to private investors increases, and longer-maturity yields face upward pressure. The Federal Reserve conducted quantitative tightening from 2017 to 2019, reducing the balance sheet by roughly $700 billion, and again beginning in 2022, with the runoff continuing across multiple years. The pace of tightening is generally slower than the pace of the preceding easing, and the eventual size of the central bank balance sheet may remain materially above pre-easing levels.
In practice
For an individual planning lifetime income during a tightening period, the implication is that longer-maturity yields are likely to be higher than they would be in the absence of the policy, supporting higher annuity payout rates and bond yields. Tightening generally accompanies a broader monetary policy tightening that includes rising target federal funds rates, but the balance sheet runoff continues independently of policy rate decisions. A professional working on lifetime income decisions should recognize quantitative tightening as one of several factors affecting the yield environment, with the federal funds rate, inflation expectations, and the term premium operating jointly.
In the Longevity Standard Framework
Quantitative tightening is supporting vocabulary in the Longevity Standard framework. As the reverse of quantitative easing, it shapes the yield environment that supports asset-backed claims by reducing rather than expanding central bank holdings of long-maturity bonds. Tightening periods generally raise longer-maturity yields and ease the spread compression that quantitative easing had produced, supporting the spread-based business model on which insurer-issued lifetime income depends. The framework's analysis of the rate environment treats quantitative tightening as one of the structural conditions that determines how the discount rate environment evolves over time, with the policy regime affecting the realized value of commercial products through its effect on carrier crediting rates and general account investment yields.
