Modeling Debt Prepayment as a Callable Bond or Swaption

Summary

The document asks for papers or books on pricing debt instruments that allow prepayment. The author has found general material on callable bonds but wants references explaining whether a prepayment option can be modeled as a call feature or as an option such as a swaption. The question spans debt and credit pricing, including mortgage-related prepayment.

The sole response recommends a starting reference suited to the reader’s mathematical background, describing it as an accessible introduction to the general idea. It suggests that more detailed models can make assumptions about default and the timing of prepayments more intricate. However, the reference itself is not identified in the supplied text, and no model specification, pricing method, evidence, or bibliography is provided. The exchange therefore points toward modeling prepayment arrival and default jointly as possible extensions, but does not answer which option analogy is appropriate or provide enough information to implement a valuation.

Key ideas

• The question concerns pricing debt whose borrower can repay before maturity.
• Callable bonds and swaptions are raised as possible analogies for the prepayment option.
• The response recommends beginning with an accessible conceptual treatment suited to the reader’s background.
• Default and the timing of prepayment are identified as assumptions that could be modeled in greater detail.
• No reference details, equations, or valuation results are supplied, so the specific modeling choice remains unanswered.

Does someone know some good literature(Papers or Books) regarding the topic how to Price debt/credit with prepayment? I just found literature about the general topic , like how to price callable bonds, but I never found literature that clearly states that a debt with a prepayment Option can be f.e. be modelled as a callable bond or a bond with a swaption. Maybe u have some recommendations?

Kosta, that would depend on your level of math or background knowledge already on the subject. I believe that a good starting point would be this. Not heavy on math but it presents the general idea. You can then expand on making the underlying assumptions (default, prepayment arrival) more intricate.
