Securitization is the process of pooling mortgage loans and turning them into securities that can be sold to investors.
Securitization is the process of pooling mortgage loans and turning them into securities that can be sold to investors.
Securitization matters because it helps lenders free up capital and keep making new loans. That is one reason mortgage lending can happen at scale rather than only through lenders keeping every loan in-house.
It also matters because borrowers sometimes hear about loan sales and servicing changes without understanding the larger system behind them. Securitization is one of the core reasons those changes happen.
Borrowers encounter securitization indirectly after closing or during market discussions about rates and lending standards.
The term becomes practical when a borrower wants to understand how a closed mortgage can move from an originator into a broader investor-backed market structure.
A lender closes many similar mortgages, and those loans are eventually pooled and used to back investor securities. That conversion from individual loans to a security-backed pool is securitization.
Securitization differs from a Mortgage-Backed Security (MBS) because securitization is the process and the MBS is the product created by that process.
It also differs from a Loan Sale. A loan sale can happen one loan at a time, while securitization usually refers to the pooling-and-security structure.
