<p>Quantitative Tightening (QT) is a monetary policy tool employed by central banks to reduce the size of their balance sheets, effectively withdrawing liquidity from the market. This is the reverse process of <a href="/NewSite/encyclopedia/quantitative-easing/" class="ency-link">Quantitative Easing</a> (QE), where central banks increase their balance sheets to inject liquidity and stimulate economic growth.</p>

<h2>How It Works</h2>
<p>Central banks typically engage in QT by allowing bonds in their portfolio to mature without replacing them, or by selling bonds back to the market. This reduces the money supply, as the bonds are effectively being taken out of circulation. Here's a simplified breakdown:</p>
<ul>
  <li>Central banks hold large quantities of bonds, purchased during QE, which pay interest to the central bank.</li>
  <li>During QT, the central bank stops replacing these bonds as they mature, or sells them back to the market.</li>
  <li>This reduces the money supply, as the bonds are no longer paying interest to the central bank, and the money used to purchase them is no longer in circulation.</li>
</ul>

<h2>Why It Matters</h2>
<p>QT is a tool used to combat inflation and stabilize the economy. Here's why it matters:</p>
<ul>
  <li><strong>Inflation Control:</strong> By reducing the money supply, QT helps to control inflation. Too much money chasing too few goods can drive up prices, so reducing the money supply can help to keep inflation in check.</li>
  <li><strong>Interest Rates:</strong> QT can also influence interest rates. When the money supply is reduced, interest rates tend to rise, as there is less money available for lending. This can help to cool down an overheating economy.</li>
  <li><strong>Market Impact:</strong> QT can have significant impacts on financial markets. As the central bank sells bonds, their prices tend to fall, and their yields (which move in the opposite direction to price) tend to rise. This can lead to changes in other asset prices, as investors adjust their portfolios.</li>
