Balance Sheet & Liquidity
Why does stopping reinvestment shrink a central bank balance sheet?
Balance-sheet reduction removes a source of central-bank demand for securities and gradually changes the quantity of reserves in the banking system. The effect on yields is usually indirect and depends on issuance, reserve abundance, money-market conditions and expectations.
How to read it
QT should be read alongside policy rates and Treasury or sovereign issuance rather than treated as an isolated tightening number.
Watch the policy-rate path, front-end OIS pricing, the 2s10s or equivalent curve shape, inflation expectations and the central bank’s own communication. Together they show whether markets are repricing the current decision, the next cycle, or the credibility of the framework.
Central-bank effects are regime-dependent. The same policy action can produce different market outcomes when inflation, growth, positioning or prior expectations differ.
