What Municipal Bonds Are and Why They Exist

Municipal bonds are debt securities issued by state and local governments, agencies, and certain public-purpose authorities to finance projects and services. This lesson introduces what a municipal bond represents, who issues them, why communities use them, and how investors should think about the basic promise behind the security.

The lesson stays focused on market foundations: the public finance purpose, the difference between borrowing and taxation, the main issuer types, and the basic distinction between general obligation and revenue bonds. Later lessons will go deeper into tax-equivalent yield, credit analysis, bond pricing, call risk, and portfolio strategy.
