Structured finance is the engineering side of finance — creating complex financial products by pooling assets, repackaging cash flows, and redistributing risk. Instead of a simple loan or bond, structured finance creates layered instruments tailored to different investor needs.
Common products include mortgage-backed securities (MBS), asset-backed securities (ABS), collateralized debt obligations (CDOs), and collateralized loan obligations (CLOs). A bank might take 1,000 car loans, bundle them into an ABS, and sell it to investors — freeing up capital to make more loans.
The structured finance market is worth trillions of dollars globally. When done responsibly, it expands credit access and distributes risk efficiently. When abused (as in the 2008 subprime crisis), it can amplify systemic risk. Post-crisis regulations now require better transparency, risk retention, and disclosure in structured products.
