Nowadays securities that blooming and popular are Asset Backed Securities. An Asset Backed Security is a security whose value and income payments are derived from and collateralized or "backed" by a specified pool of underlying assets. The pool of assets is typically a group of small and illiquid assets that are unable to be sold individually. Pooling the assets into financial instruments allows them to be sold to general investors, a process called securitization, and allows the risk of investing in the underlying assets to be diversified because each security will represent a fraction of the total value of the diverse pool of underlying assets. The pools of underlying assets can include common payments from credit cards, auto loans, and mortgage loans. One incentive for banks to create securitized assets is to remove risky assets from their balance sheet by having another institution assume the credit risk, so that they will receive cash in return. This allows banks to invest more of their capital in new loans or other assets and possibly have a lower capital requirement. This practice will trigger the economic growth of a nation.
