Banks and mortgage lenders collect mortgages from borrowers, then package and sell them to government-sponsored entities like Fannie Mae and Freddie Mac. These entities further pool these mortgages, turning them into tradable securities known as MBS. Investors can buy these securities, receiving payments based on the interest and principal repayments made by homeowners.

During the 2008 financial crisis, MBS played a central and controversial role. Risky lending practices, subprime mortgages packaged into MBS, and complex financial instruments contributed to the housing market collapse. The widespread default on these mortgages led to significant losses for investors and financial institutions, triggering a global financial crisis.

MBS, particularly those backed by high-risk mortgages, faced substantial downgrades in credit ratings, causing investor panic and market turmoil. The crisis revealed weaknesses in the housing market, financial regulations, and the interconnectedness of global financial institutions.

Understanding the complexities and risks associated with MBS is crucial in preventing similar crises and ensuring a stable housing and financial market environment.
