2. Credit risk: the risk that the bond issuer or debtor cannot repay the debt in full and on time. If the bond rating is downgraded, the bond price may fall, resulting in losses.

3. Market risk: the fluctuation of market price or trading volume leads to the fluctuation of bond price, which brings investment risk.

4. Liquidity risk: Some bonds with poor liquidity may be difficult to sell quickly.

5. Inflation risk: Inflation will lead to a decline in the real purchasing power of cash income, which may lead to a decline in the real yield of bonds.

6. Policy risk: changes in government policies may have an impact on specific types of bonds, thus affecting the price and yield of bonds.

7. Foreign exchange risk: If bonds are denominated in foreign currencies, exchange rate fluctuations may affect bond prices and investment returns.

Matters needing attention in bond investment risk

1. Assessing credit risk: Investors should carefully assess the credit status of bond issuers or debtors to avoid buying bonds with high default risk.

5. Pay attention to the macroeconomic environment: The performance of the bond market is usually closely related to the macroeconomic environment. Investors should pay attention to the trend of macroeconomic environment in order to adjust their investment portfolio according to market trends.
