Interest Rate Expectations: Anticipated changes in the Federal Reserve's monetary policy significantly impact bond yields, and consequently, prices. Higher expected rates typically decrease bond prices. Inflation Expectations: Rising inflation erodes the purchasing power of future fixed income payments, leading to lower bond prices to compensate for this risk. Economic Growth: Stronger economic growth often leads to higher interest rates and inflation, negatively affecting bond prices. Conversely, weaker growth can boost demand for bonds. Supply and Demand: Increased Treasury supply can push bond prices lower, while higher demand from investors can drive prices upward. Global Events: Geopolitical instability or major economic events in other countries can influence investor demand for US Treasury bonds as a safe haven asset.
