Debentures are long-term debt instruments that allow companies and governments to raise capital without pledging specific assets as collateral. These unsecured bonds appeal to investors seeking portfolio diversification and fixed income, though they carry risks tied to the issuer’s creditworthiness. 

While government-issued debentures are generally low-risk due to sovereign backing, corporate debentures rely on the company’s financial health and reputation, making credit ratings an essential consideration. 

There are various types: convertible debentures can later be exchanged for company stock, while nonconvertible ones cannot but typically offer higher interest rates; similarly, secured debentures are backed by company assets, whereas unsecured ones are not, increasing the investment risk but potentially offering higher yields. 

Finsum: While they provide regular income and reduced exposure to market volatility, investors must weigh those benefits against interest rate sensitivity and potential default risk.
