Securitization transforms illiquid financial assets into tradable securities. A pool of loans or receivables is transferred to a special legal entity. That entity issues bonds to investors. The originator receives immediate cash, freeing regulatory capital for new lending. The benefits reach well beyond the originator: issuers free up balance-sheet capacity, investors gain access to diversified and tradable exposures, and broader economies and financial markets gain liquidity and more efficient credit allocation.
A securitization brings together several parties, and the roles they play determine how cash and risk move through the structure.
- Originator: the entity that created the underlying assets (bank, auto lender, credit card company)
- SPV/SPE: a bankruptcy-remote entity that holds the asset pool and issues securities
- Servicer: collects borrower payments and passes them through the waterfall (often the originator itself, earning 25-50 bps per year)
KEY: Bankruptcy remoteness is the entire reason the SPV exists. Assets are transferred through a true sale that severs ownership ties. If the originator files for bankruptcy, its creditors have no claim on the SPV's assets.
Common mistakes
- Confusing the SPV with the originator. After a true sale, the originator has no ownership of the assets. ABS investors have a claim only against the SPV pool. Trap: selecting the originator as the party bearing borrower credit risk after securitization.
- Reversing the direction of loss absorption. Losses flow from the bottom up. Equity absorbs first, then mezzanine, then senior. Seniority means priority of payment and last in line for losses. Trap: stating the senior tranche absorbs the first 80% of losses because it is 80% of the capital structure.
- Treating subordination and overcollateralization as identical. Subordination = junior tranches absorb losses first. OC = extra collateral beyond securities issued. Both are internal, but different mechanisms. Trap: selecting "overcollateralization" when the question describes junior tranches bearing first losses.
Bottom line
- Securitization transfers assets to a bankruptcy-remote SPV: investors hold a claim on the SPV pool, not the originator
- True sale severs ownership ties: if the originator goes bankrupt, SPV investors are unaffected
- Four internal credit enhancements: subordination, overcollateralization, excess spread, reserve accounts
- Losses flow up (equity first); payments flow down (senior first), as set by the waterfall
Exam shortcut
When the exam describes a feature and asks "which type of credit enhancement?", map it: junior tranches taking losses = subordination. Collateral exceeding issuance = overcollateralization. Interest income exceeding outflows = excess spread. Cash set aside at closing = reserve account. Remember: "Losses rise, payments fall." Senior gets paid first and loses last. Equity gets paid last and loses first.
