Should you invest into bonds? Learn about factors that influence the price of a bond, such as interest rates, credit ratings, yield, and market sentiment.The response of the yield curve to changes in the demand for, or supply of, bonds will depend on the nature of the change. The spike in bond yields presents an opportunity for fixed income investors to earn capital gains and diversify portfolios. In recent months, there has been a substantial increase in the supply of corporate bonds. When demand for a bond increases, its price rises, and conversely, when demand decreases, its price falls. Higher inflation expectations decrease demand for bonds and increase their supply. Both factors result in lower bond prices and higher interest rates. Or, in Keynes's framework, the demand for money increases with inflation expectations because people want to maintain real money balances.
