Core Insights - The article discusses the significant differences between government bonds and corporate bonds, focusing on their risk characteristics and investment attributes [1][2][3] Group 1: Credit Risk - Government bonds are issued by the central government and backed by national credit, resulting in a very low credit risk level [1] - Corporate bonds are issued by domestic companies and their credit risk is closely tied to the financial health and profitability of the issuing company, leading to a higher overall credit risk compared to government bonds [1] Group 2: Default Risk - Government bonds have the highest stability in terms of repayment, supported by stable cash flows from taxes and bond issuance, making default almost impossible [2] - Corporate bonds depend on the operational performance and cash flow of the issuing company, which can lead to potential defaults if the company faces financial difficulties [2] Group 3: Liquidity Risk - Government bonds typically have larger issuance sizes and are actively traded across various platforms, providing strong asset liquidity [2] - Corporate bonds' liquidity is influenced by factors such as issuance size and credit rating, with many corporate bonds having lower trading activity, especially those from smaller companies [2] Group 4: Market Risk - Both government and corporate bonds are sensitive to market interest rate changes, but their sensitivity differs due to variations in coupon rates and maturity structures [2] - Government bonds generally have lower coupon rates and a higher proportion of long-term bonds, making them more sensitive to rising interest rates compared to corporate bonds [2] Group 5: Policy Environment - Government bonds are influenced by macroeconomic policies, but such adjustments do not affect their repayment safety [3] - Corporate bonds are more susceptible to industry-specific policies and regulations, which can increase credit and market risks for the issuing companies [3]
