What Is Securitization? Securitization is the process of pooling financial assets (like mortgages, auto loans, credit card receivables) and transforming them into tradable securities—typically asset-backed securities (ABS) or mortgage-backed securities (MBS).Example: A bank bundles 1,000 mortgages into a trust. The trust issues bonds that represent ownership in the pool’s cash flows. Investors buy the bonds. The borrowers keep paying their mortgages, and that money flows to investors. | Antoine
