Risk Management interview preparation
Market, credit and operational risk, plus model validation, regulatory capital, liquidity and ALM, the statistical foundations and the Indian regulatory syllabus. Every question is either traced to a named firm from a public candidate report, or tagged at desk level when we could not trace it — and answers lead with the point, then the mechanism, then the limitation.

032What is structured finance, how would you evaluate it, and what are the credit risks?Moody'sCredit Risk · New York · 2024
Say this
Structured finance is taking a pool of cash-flow-generating assets, putting it in a bankruptcy-remote vehicle, and slicing the cash flows into tranches of different seniority. You evaluate it in three layers: the collateral, the structure, and the parties.
Then walk it
- Layer one, the collateral. Pool composition, weighted average life, seasoning, geographic and obligor concentration, historical default and prepayment behaviour, and how the underwriting was done. Everything downstream depends on this, and it's where the 2007 failure actually was.
- Layer two, the structure. Where does the cash go, and in what order. Credit enhancement comes from subordination, excess spread, overcollateralisation and reserve accounts. Then the triggers: performance triggers that turn a pro-rata waterfall sequential, and cash-trapping mechanics.
- Layer three, the parties. Originator, servicer, trustee, swap counterparty. Servicer quality drives recoveries, and servicer failure has broken deals whose collateral was fine. Then the legal question: is the true sale robust, and is the SPV actually bankruptcy remote?
- How I'd analyse it: model the pool, run default and prepayment scenarios, and see at what cumulative loss each tranche takes its first rupee of loss. That break-even loss compared with the expected loss is the real measure of a tranche's safety.
- The credit risks specific to tranching. Correlation risk: a senior tranche is a bet on correlation, not just on average defaults, because it only fails if losses cluster. Cliff risk: a mezzanine tranche goes from untouched to wiped out over a narrow loss range, so it's far more convex than its rating suggests.
- Then prepayment and extension risk on the timing, basis risk if the assets and liabilities reprice off different benchmarks, and originator alignment. Skin in the game is why post-crisis rules require the sponsor to retain a slice.
- The Indian version worth naming: pass-through certificates and direct assignments on NBFC loan pools, where the live risks are servicer concentration, priority-sector motivation on the buyer side, and the 2018 to 2019 NBFC liquidity episode showing how quickly refinancing assumptions fail.
- And the honest limitation: the rating of a structured tranche is far more model-dependent than a corporate rating. Small changes in a correlation assumption move a AAA to a BBB, and that is exactly what happened to CDOs.
Where candidates lose it
Explaining tranching and stopping. The two things a credit risk interviewer at a rating agency wants are the sensitivity of senior tranches to correlation rather than to average default rates, and the cliff-risk convexity of mezzanine. Naming the servicer and the true-sale question shows you've read a deal document, not a textbook.
