FixedBond

FixedBond instrument object

Description

Create and price a FixedBond instrument object for one of more Fixed Bond instruments using this workflow:

1. Use fininstrument to create a FixedBond instrument object for one of more Fixed Bond instruments.

2. Use ratecurve to specify a curve model for the FixedBond instrument object or use a HullWhite, BraceGatarekMusiela, SABRBraceGatarekMusiela, or LinearGaussian2F model.

3. Choose a pricing method.

   • When using a ratecurve use finpricer to specify a Discount pricing method for one or more FixedBond instruments.

   • When using a HullWhite, BraceGatarekMusiela, SABRBraceGatarekMusiela, or LinearGaussian2F model, use finpricer to specify an IRMonteCarlo pricing method for one or more FixedBond instruments.

For more detailed information on this workflow, see Get Started with Workflows Using Object-Based Framework for Pricing Financial Instruments.

For more information on the available models and pricing methods for a FixedBond instrument, see Choose Instruments, Models, and Pricers.

Creation

Syntax

FixedBondObj = fininstrument(InstrumentType,'CouponRate',couponrate_value,'Maturity',maturity_date)

FixedBondObj = fininstrument(___,Name,Value)

Description

FixedBondObj = fininstrument(InstrumentType,'CouponRate',couponrate_value,'Maturity',maturity_date) creates a FixedBond object for one of more Fixed Bond instruments by specifying InstrumentType and sets the properties for the required name-value pair arguments CouponRate and Maturity.

The FixedBond instrument supports a vanilla bond, a stepped coupon bond, and an amortizing bond. For more information, see More About.

FixedBondObj = fininstrument(___,Name,Value) sets optional properties using additional name-value pairs in addition to the required arguments in the previous syntax. For example, FixedBondObj = fininstrument("FixedBond",'CouponRate',0.034,'Maturity',datetime(2019,1,30),'Period',4,'Basis',1,'Principal',100,'FirstCouponDate',datetime(2016,1,30),'EndMonthRule',true,'Name',"fixedbond_instrument") creates a FixedBond option with a coupon rate of 0.34 and a maturity of January 30, 2019. You can specify multiple name-value pair arguments.

Input Arguments

InstrumentType — Instrument type

string with value "Fixedbond" | string array with values of "Fixedbond" | character vector with value 'FixedBond' | cell array of character vectors with values of 'FixedBond'

Instrument type, specified as a string with the value of "FixedBond", a character vector with the value of 'FixedBond', an NINST-by-1 string array with values of "FixedBond", or an NINST-by-1 cell array of character vectors with values of 'FixedBond'.

Data Types: char | cell | string

Name-Value Arguments

Specify required and optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: FixedBondObj = fininstrument("FixedBond",'CouponRate',0.034,'Maturity',datetime(2019,1,30),'Period',4,'Basis',1,'Principal',100,'FirstCouponDate',datetime(2016,1,30),'EndMonthRule',true,'Name',"fixedbond_instrument")

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 nonbusiness 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 nonbusiness 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.

Data Types: char | cell | string

Holidays — Holidays used in computing business days

NaT (default) | datetimes | cell array of character vectors | date string array | serial date numbers

Holidays used in computing business days, specified as the comma-separated pair consisting of 'Holidays' and dates using an NINST-by-1 vector of datetimes, serial date numbers, cell array of date character vectors, or date string array. For example:

H = holidays(datetime('today'),datetime(2025,12,15));
FixedBondObj = fininstrument("FixedBond",'CouponRate',0.34,'Maturity',datetime(2025,12,15),'Holidays',H)

Data Types: double | cell | datetime | string

EndMonthRule — End-of-month rule flag for generating dates when Maturity is end-of-month date for month with 30 or fewer days

true (in effect) (default) | scalar logical value of true or false | vector of logical values of true or false

End-of-month rule flag for generating dates when Maturity is an end-of-month date for a month with 30 or fewer days, specified as the comma-separated pair consisting of 'EndMonthRule' and a scalar logical value or an NINST-by-1 vector of logicals with values of true or false.

• If you set EndMonthRule to false, the software ignores the rule, meaning that a payment date is always the same numerical day of the month.

• If you set EndMonthRule to true, the software sets the rule on, meaning that a payment date is always the last actual day of the month.

Data Types: logical

IssueDate — Bond issue date

NaT (default) | datetime | serial date number | date character vector | date string | vector of datetimes | vector of serial date numbers | cell array of date character vectors | date string array

Bond issue date, specified as the comma-separated pair consisting of 'IssueDate' and a scalar datetime, serial date number, date character vector, date string or an NINST-by-1 vector of datetimes, serial date numbers, cell array of date character vectors, or date string array.

If you use date character vectors or date strings, the format must be recognizable by datetime because the IssueDate property is stored as a datetime.

Data Types: double | char | cell | string | datetime

FirstCouponDate — Irregular first coupon date

NaT (default) | datetime | serial date number | date character vector | date string | vector of datetimes | vector of serial date numbers | cell array of date character vectors | date string array

Irregular first coupon date, specified as the comma-separated pair consisting of 'FirstCouponDate' and a scalar datetime, serial date number, date character vector, date string or an NINST-by-1 vector of datetimes, serial date numbers, cell array of date character vectors, or date string array.

When FirstCouponDate and LastCouponDate are both specified, FirstCouponDate takes precedence in determining the coupon payment structure. If you do not specify FirstCouponDate, the cash flow payment dates are determined from other inputs.

If you use date character vectors or date strings, the format must be recognizable by datetime because the FirstCouponDate property is stored as a datetime.

Data Types: double | cell | char | string | datetime

LastCouponDate — Irregular last coupon date

NaT (default) | datetime | serial date number | date character vector | date string | vector of datetimes | vector of serial date numbers | cell array of date character vectors | date string array

Irregular last coupon date, specified as the comma-separated pair consisting of 'LastCouponDate' and a scalar datetime, serial date number, date character vector, date string or an NINST-by-1 vector of datetimes, serial date numbers, cell array of date character vectors, or date string array.

If you specify LastCouponDate but not FirstCouponDate, LastCouponDate determines the coupon structure of the bond. The coupon structure of a bond is truncated at LastCouponDate, regardless of where it falls, and is followed only by the bond's maturity cash flow date. If you do not specify LastCouponDate, the cash flow payment dates are determined from other inputs.

If you use date character vectors or date strings, the format must be recognizable by datetime because the LastCouponDate property is stored as a datetime.

Data Types: double | cell | char | string | datetime

StartDate — Forward starting date of payments

NaT (default) | datetime | serial date number | date character vector | date string | vector of datetimes | vector of serial date numbers | cell array of date character vectors | date string array

More About

Fixed-Rate Note

A fixed-rate note is a long-term debt security with a preset interest rate and maturity, by which the interest must be paid.

The principal might or might not be paid at maturity. In Financial Instruments Toolbox™, the principal is always paid at maturity. For more information, see Fixed-Rate Note.

Vanilla Bond

A vanilla coupon bond is a security representing an obligation to repay a borrowed amount at a designated time and to make periodic interest payments until that time.

The issuer of a bond makes the periodic interest payments until the bond matures. At maturity, the issuer pays to the holder of the bond the principal amount owed (face value) and the last interest payment.

Stepped Coupon Bond

A step-up bond and a step-down bond are debt securities with a predetermined coupon structure over time.

With these instruments, coupons increase (step up) or decrease (step down) at specific times during the life of the bond.

Bond with an Amortization Schedule

An amortized bond is treated as an asset, with the discount amount being amortized to interest expense over the life of the bond.
