Explain how securitisation works and the role of the special purpose entity
The idea
Securitisation pools loans and sells claims on their cash flows as securities. The originator sells the loans to a special purpose entity, and the sale must be a true sale that puts the assets beyond the reach of the originator's creditors — that bankruptcy remoteness is the point of the structure, and it lets the securities be rated on the loans rather than on the originator. A servicer continues to collect payments. The benefits are cheaper funding for the originator and access for investors to loan exposures they could not otherwise buy, in tranches matched to their risk appetite.
A practice question
What is the purpose of the special purpose entity in a securitisation?
- To service the underlying loansWhy not: Servicing usually stays with the originator, which is why the borrower notices nothing. The entity's purpose is legal isolation, not administration.
- To hold the assets separately — correct
- To guarantee the securities issuedWhy not: It guarantees nothing — it has no capital of its own beyond the assets transferred to it. Credit enhancement comes from structure, not from a promise.
Separation puts them beyond the reach of the originator's creditors. Bankruptcy remoteness is what allows the securities to be rated on the quality of the loan pool rather than on the originator's own credit.
A harder one
Why can securitisation lower an originator's funding cost?
- Because the securities can be rated higher — correct
- Because securitised loans carry no credit riskWhy not: The loans carry exactly the credit risk they always did. What changes is whose credit risk sits alongside it.
- Because regulators subsidise securitisationWhy not: No subsidy exists, and capital rules have generally tightened around it.
They depend on the isolated pool rather than on the firm, so they can be rated above the originator's own credit. A weak bank with a strong loan pool can fund at the pool's cost rather than its own, and the separation is the whole mechanism.
The hardest tier
Why does the sale of assets to the special purpose entity have to be a true sale rather than a pledge?
- Because a pledge would require regulatory approvalWhy not: Pledges are routine and need no special approval. The objection is what happens in an insolvency.
- Because a pledge cannot be recorded in the accountsWhy not: It can be, and is. Secured borrowing is ordinary accounting — the problem is that the assets stay on the balance sheet.
- Because under a pledge the assets stay the originator's — correct
If a court can reconsolidate the assets, investors are exposed to the originator after all. The legal characterisation of the transfer is therefore central to the rating, not a formality.
