What is securitization, and how do MBS/CMOs relate to bank risk?

• A. Pooling assets into securities sold to investors; MBS/CMOs transfer credit risk but can transfer and concentrate risk if underwriting is weak.
• B. Issuing new stocks to investors.
• C. Setting the interest rates on central bank loans.
• D. Hedging currency risk only.

Answer: (A)

Securitization pools a bunch of loans or other assets and then issues securities backed by the cash flows those assets generate. Mortgage-backed securities and collateralized mortgage obligations are prime examples: they take borrowers’ mortgage payments and pass them through to investors, while the securities are structured into tranches that allocate credit risk among buyers.

This process moves credit risk away from the originating bank onto investors and can improve liquidity and capital treatment for the bank. But the risk isn’t eliminated. If the underlying underwriting is weak, the pool can perform poorly, and that risk can be transferred but also concentrated in specific tranches or among investors holding those securities. In other words, securitization can shift risk off the bank’s balance sheet while potentially concentrating or spreading it in ways that can still affect banks’ overall risk exposure if loan quality deteriorates or if exposure is widespread across similar deals.

Not about issuing new stock, setting central-bank rates, or hedging only currency risk.
