国债和企业债风险差异有多大？

Core Viewpoint - The article highlights the significant differences between government bonds and corporate bonds in terms of credit risk, market risk, liquidity risk, and tax policy impacts, emphasizing the importance of understanding these differences for investment decisions [1][2][3]. Credit Risk - Government bonds are issued by the central government and are backed by fiscal revenue, making them highly reliable with no default risk. In contrast, corporate bonds depend on the issuing company's operational performance and cash flow, leading to potential default risks, especially for lower-rated corporate bonds [1]. Market Risk - Market interest rate changes affect all bonds, but corporate bonds exhibit greater price volatility due to credit risk premiums. When market rates rise, corporate bonds typically experience a more significant price decline compared to government bonds. Economic downturns can further widen credit spreads for corporate bonds, amplifying price fluctuations [1]. Liquidity Risk - Government bonds have high trading activity and liquidity, allowing investors to easily buy and sell. Corporate bonds, however, show varying liquidity levels based on credit ratings and issuance size, with lower-rated corporate bonds facing higher liquidity risks and challenges in finding buyers [2]. Tax Policy Impact - Interest income from government bonds is tax-exempt, while corporate bond interest is subject to personal or corporate income tax. This tax difference results in lower actual returns for corporate bond investors compared to nominal returns, affecting perceived risk and return stability [2]. Overall Comparison - The differences in credit risk, market risk, liquidity risk, and policy impacts between government and corporate bonds stem from their distinct issuing entities. These differences influence their roles in investment portfolios, necessitating a thorough assessment of risk characteristics based on individual investor profiles [3].
