Market Interest Rates: Higher interest rates generally lead to lower bond prices as newly issued bonds become more attractive. Lower interest rates tend to increase bond prices.

Credit Risk: Changes in the perceived creditworthiness of the bond issuer (likelihood of default) directly impact bond prices. Deteriorating credit quality lowers prices, while improved creditworthiness raises them.

Inflation Expectations: Rising inflation expectations usually cause bond yields to rise, leading to lower bond prices. Conversely, decreasing inflation expectations tend to boost bond prices.

Economic Growth: Strong economic growth can sometimes lead to higher interest rates, negatively impacting bond prices. Slowing economic growth may lead to lower interest rates and higher bond prices.

Maturity Date: Bonds with longer maturities are generally more sensitive to interest rate changes, making their prices more volatile than those of short-term bonds.

Supply and Demand: Basic supply and demand principles apply to bonds as well. Higher demand for a specific bond increases its price, while increased supply may decrease its price.

Liquidity: Bonds that are actively traded (liquid) tend to be more easily bought and sold, potentially affecting their price compared to less liquid bonds.

Call Provisions: If a bond is callable (issuer can redeem it before maturity), this can limit its potential upside and affect its price, especially when interest rates are falling.
