Market Interest Rates: Rising rates generally decrease bond values, as newer bonds offer higher yields, making existing, lower-yielding bonds less attractive.

Inflation Expectations: Higher inflation erodes future bond values, reducing their present price to compensate for decreased purchasing power.

Economic Growth: Stronger economic growth can lead to higher interest rates, impacting bond prices negatively, and vice versa during recessions.

Credit Risk: Changes in the perceived creditworthiness of the bond issuer (government or corporation) directly affect bond prices; higher risk lowers the price.

Liquidity: Lower liquidity means it's harder to sell the bond quickly, leading to a lower price compared to more liquid bonds.

Maturity Date: Longer-term bonds are more sensitive to interest rate changes, experiencing larger price fluctuations than shorter-term bonds.

Supply and Demand: Increased supply of similar bonds or decreased demand will lower prices, while reduced supply or increased demand will raise prices.
