Residential Mortgage-Backed Securities (RMBS) are a type of financial instrument that is created from a pool of residential debt. This debt can include mortgages, home-equity loans, and subprime mortgages, which are then sold to investors. RMBS offer a way for banks and other financial institutions to free up capital, while providing investors with a potential source of revenue.
