Brady bonds, proposed by U.S. Treasury Secretary Nicholas Brady in 1989, aimed to help reduce debt in developing countries, particularly in Latin America facing defaults in the 1980s. These long-term bonds have features such as call options, step-up coupon payments linked to inflation, and allow commercial banks to replace non-performing debts. However, they carry risks including interest rate risk, sovereign risk due to political instability, and the potential for default by the issuing country.
