Using a Vector Autoregressive (VAR) model, we analysed the dynamic interactions between key economic variables, including Treasury yields, QE amounts, GDP, inflation rates, and Federal Funds rates. The quantitative easing policies pursued by the US Federal Reserve have led to increased scrutiny of the debts of countries issuing reserve currencies. The US sovereign debt was significantly affected by these policies, but there has not been much work on the direct dynamics between QE policy and the value of sovereign debt for the US market. The study strives to contribute to the literature by estimating the US sovereign debt valuation reaction to changes in the balance sheet caused by the quantitative easing policy. Valuation of US sovereign debts is an important issue due to the influential role of US sovereign bonds in diverse international financial markets. Our findings indicate that large-scale asset purchases cause changes in U.S. sovereign debt bond prices and their valuation.enQuantitative Easing policyUS sovereign debtVector Autoregressive (VAR) modelTreasury yieldsQE amounts.Article
