Central to bank risk management is credit risk, as discussed in Week 6 and Week 8.
Traditionally, banks adopt several mechanisms to manage credit risk:
In addition, FIs can use derivatives (e.g., forward, options, swaps) to manage their credit risk.
However, FIs now increasingly use loan sales and securitisation to control credit risk.
Traditional short-term loan sales
Leveraged loan sales
Note
The definition of “leveraged loan” is ambiguous: some use spreads (e.g., +125bps) and others use rating criteria (e.g., BB- or lower).
Note
Leveraged loans can be:
Two basic forms by which loans can be transferred from seller to buyer.

Sellers
Apart from credit risk management, there are some other reasons for FIs to sell loans.
Asset securitisation is another mechanism to manage credit risk, interest rate risk, liquidity and more.
The mechanism is:
Note
The underlying loans belong to the ultimate investors in these ABS.
Note
The underlying loans belong to the SIV.
SIV acts like a traditional bank: hold loans until maturity and issue short-term debt instruments.
The major forms of asset securitisation are:
Pass-through securities “pass through” payments by underlying borrowers (e.g., household borrowers of mortgages) to secondary market investors holding an interest in the mortgage pool.
Note
Pass-throughs are the primary mechanism for securitisation.
CMO is a second and growing securitisation mechanism.
Class A
Class B
Class C
MBB or covered bonds are the third securitisation vehicle.
They differ from pass-throughs and CMOs in two main aspects:
Note
Underlying mortgages are more of collateral for the MBBs.
The process involved:
However, MBBs are less appealing to FIs for a number of reasons:
Caution
But FIs issuing MBBs could gain at the cost of taxpayers’ money (deposit insurance)! Let’s see why.
Consider an FI with $20 million in long-term mortgages as assets financed with $10 million in short-term uninsured deposits and $10 million in insured deposits.
Assets | Liabilities | ||
---|---|---|---|
Long-term mortgages | $20 | Insured deposits | $10 |
Uninsured deposits | $10 | ||
$20 | $20 |
To lower the duration gap and funding cost, the FI may choose securitisation via MBB issue.
Assets | Liabilities | ||
---|---|---|---|
Collateral (market value of segregated mortgages) | $12 | MBB issue | $10 |
Other mortgages | 8 | Insured deposits | $10 |
$20 | $20 |
Important
The $10 million insured deposits are now backed only by $8 million in unpledged assets!!
The major use of the three securitisation vehicles (pass-throughs, CMOs and MBBs) packages fixed-rate mortgages. But securitisation can also be applied for other assets:
