Bootstrap default probability curve from bond prices

Syntax

[ProbabilityData,HazardData]
= bondDefaultBootstrap(ZeroData,MarketData,Settle)

[ProbabilityData,HazardData]
= bondDefaultBootstrap(___,Name,Value)

Description

[ProbabilityData,HazardData] = bondDefaultBootstrap(ZeroData,MarketData,Settle) bootstraps the default probability curve from bond prices.

Using bondDefaultBootstrap, you can:

Extract discrete default probabilities for a certain period from market bond data.
Interpolate these default probabilities to get the default probability curve for pricing and risk management purposes.

example

[ProbabilityData,HazardData] = bondDefaultBootstrap(___,Name,Value) adds optional name-value pair arguments.

In bondDefaultBootstrap, the first column of the ProbabilityData output and the first column of the HazardData output contain the respective ending dates for the corresponding default probabilities and hazard rates. However, the starting dates used for the computation of the time ranges for default probabilities can be different from those of hazard rates. For default probabilities, the time ranges are all computed from the Settle date to the respective end dates shown in the first column of ProbabilityData. In contrast, the time ranges for the hazard rates are computed using the Settle date and the first column of HazardData, so that the first hazard rate applies from the Settle date to the first market date, the second hazard rate from the first to the second market date, and so on, and the last hazard rate applies from the second-to-last market date onwards.

End-of-month rule flag, specified as the comma-separated pair consisting of 'EndMonthRule' and a nonnegative integer, 0 or 1, using a NINST-by-1 vector. This rule applies only when Maturity is an end-of-month date for a month having 30 or fewer days.

0 = Ignore rule, meaning that a bond coupon payment date is always the same numerical day of the month.
1 = Set rule on, meaning that a bond coupon payment date is always the last actual day of the month.

Data Types: double

`IssueDate` — Bond issue date
if `IssueDate` not specified, cash flow payment dates determined from other inputs (default) | datetime array | string array | date character vector

Bond issue date, specified as the comma-separated pair consisting of 'IssueDate' and a N-by-1 vector using a datetime array, string array, or date character vectors.

To support existing code, bondDefaultBootstrap also accepts serial date numbers as inputs, but they are not recommended.

Data Types: char | datetime | string

`FirstCouponDate` — First actual coupon date
if you do not specify a `FirstCouponDate`, cash flow payment dates are determined from other inputs (default) | datetime scalar | string scalar | date character vector

First actual coupon date, specified as the comma-separated pair consisting of 'FirstCouponDate' and a scalar datetime, string, or date character vector. FirstCouponDate is used when a bond has an irregular first coupon period. When FirstCouponDate and LastCouponDate are both specified, FirstCouponDate takes precedence in determining the coupon payment structure.

To support existing code, bondDefaultBootstrap also accepts serial date numbers as inputs, but they are not recommended.

Data Types: char | datetime | string

`LastCouponDate` — Last actual coupon date
if you do not specify a `LastCouponDate`, cash flow payment dates are determined from other inputs (default) | datetime scalar | string scalar | date character vector

Last actual coupon date, specified as the comma-separated pair consisting of 'LastCouponDate' and a scalar datetime, string, or date character vector. LastCouponDate is used when a bond has an irregular last coupon period. In the absence of a specified FirstCouponDate, a specified LastCouponDate determines the coupon structure of the bond. The coupon structure of a bond is truncated at the LastCouponDate, regardless of where it falls, and is followed only by the bond's maturity cash flow date.

To support existing code, bondDefaultBootstrap also accepts serial date numbers as inputs, but they are not recommended.

Data Types: char | datetime | string

`StartDate` — Forward starting date of payments
if you do not specify `StartDate`, effective start date is `Settle` date (default) | datetime scalar | string scalar | date character vector

Forward starting date of payments, specified as the comma-separated pair consisting of 'StartDate' and a scalar datetime, string, or date character vector. StartDate is when a bond actually starts (the date from which a bond cash flow is considered). To make an instrument forward-starting, specify this date as a future date.

To support existing code, bondDefaultBootstrap also accepts serial date numbers as inputs, but they are not recommended.

Data Types: char | datetime | string

`BusinessDayConvention` — Business day conventions
`'actual'` (default) | character vector or string object with values`'actual'`, `'follow'`, `'modifiedfollow'`, `'previous'`or `'modifiedprevious'`

Business day conventions, specified as the comma-separated pair consisting of 'BusinessDayConvention' and a character vector or a string object. The selection for business day convention determines how nonbusiness days are treated. Nonbusiness days are defined as weekends plus any other date that businesses are not open (for example, statutory holidays). Values are:

'actual' — Nonbusiness days are effectively ignored. Cash flows that fall on non-business days are assumed to be distributed on the actual date.
'follow' — Cash flows that fall on a nonbusiness day are assumed to be distributed on the following business day.
'modifiedfollow' — Cash flows that fall on a non-business day are assumed to be distributed on the following business day. However if the following business day is in a different month, the previous business day is adopted instead.
'previous' — Cash flows that fall on a nonbusiness day are assumed to be distributed on the previous business day.
'modifiedprevious' — Cash flows that fall on a nonbusiness day are assumed to be distributed on the previous business day. However if the previous business day is in a different month, the following business day is adopted instead.

Bootstrap Default Probability

A default probability curve can be bootstrapped from a collection of bond market quotes.

Extracting discrete default probabilities for a certain period from market bond data is represented by the formula

$P r i c e = D i s c (t_{N}) \times F V \times Q (t_{N}) + \frac{C}{f} \times \sum_{i = 1}^{N} D i s c (t_{i}) \times Q (t_{i}) + \sum_{(i = 1)}^{N} D i s c (t_{i}) \times R (t_{i}) \times (Q (t_{i} - 1) - Q (t_{i}))$

where:

FV — Face value

Q — Survival probability

C — Coupon

R — Recovery amount

f — Payment frequency (for example, 2 for semiannual coupon bonds)

The default probability is:

DefaultProbability = 1 – SurvivalProbability

R2022b: Serial date numbers not recommended

Although bondDefaultBootstrap supports serial date numbers, datetime values are recommended instead. The datetime data type provides flexible date and time formats, storage out to nanosecond precision, and properties to account for time zones and daylight saving time.

To convert serial date numbers or text to datetime values, use the datetime function. For example:

t = datetime(738427.656845093,"ConvertFrom","datenum");
y = year(t)

y =

        2021

There are no plans to remove support for serial date number inputs.
