Tahvil ihraç refers to the issuance of bonds by governments or corporations to raise funds. These bonds are essentially loans made by investors to the issuer, who promises to pay back the principal amount along with interest over a specified period. Investors buy these bonds as a way to earn interest income while contributing to financing projects or operations. The terms of the bond, including interest rates and maturity dates, are outlined in a document called a bond prospectus. This process is a key component of financial markets, facilitating capital flow and investment opportunities.
