instbond

Construct bond instrument

Syntax

InstSet = instbond(CouponRate,Settle,Maturity)

InstSet = instbond(InstSet,CouponRate,Settle,Maturity)

InstSet = instbond(___,Period,Basis,EndMonthRule,IssueDate,FirstCouponDate,LastCouponDate,StartDate,Face)

[FieldList,ClassList,TypeString] = instbond

Description

InstSet = instbond(CouponRate,Settle,Maturity) creates a new instrument set containing Bond instruments.

InstSet = instbond(InstSet,CouponRate,Settle,Maturity) adds Bond instruments to an existing instrument set.

InstSet = instbond(___,Period,Basis,EndMonthRule,IssueDate,FirstCouponDate,LastCouponDate,StartDate,Face) adds optional arguments.

[FieldList,ClassList,TypeString] = instbond lists field meta-data for the Bond instrument.

Examples

Create a Bond Instrument

Create a new instrument variable with the following information:

CouponRate= [0.035;0.04];
Settle= datetime(2013,11,1); 
Maturity = datetime(2014,11,1); 
Period =1; 

InstSet = instbond(CouponRate, Settle, Maturity, ...
Period)

InstSet = struct with fields:
        FinObj: 'Instruments'
    IndexTable: [1×1 struct]
          Type: {'Bond'}
     FieldName: {{11×1 cell}}
    FieldClass: {{11×1 cell}}
     FieldData: {{11×1 cell}}

Display the instrument set.

Input Arguments

InstSet — Instrument variable

structure

Instrument variable, specified only when adding Bond instruments to an existing instrument set. For more information on the InstSet variable, see instget.

Data Types: struct

CouponRate — Coupon rate indicating the annual percentage rate

decimal

Coupon rate indicating the annual percentage rate, specified as an NINST-by-1 vector or an NINST-by-1 cell array of decimal annual rates, or decimal annual rate schedules. For the latter case of a variable coupon schedule, each element of the cell array is a NumDates-by-2 cell array, where the first column is dates and the second column is its associated rate. The date indicates the last day that the coupon rate is valid.

Data Types: double | cell

Settle — Settlement dates

datetime array | string array | date character vector

Settlement dates, specified as scalar or an NINST-by-1 vector using a datetime array, string array, or date character vectors.

Note

Settle must be earlier than Maturity.

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

Maturity — Maturity dates

datetime array | string array | date character vector

Maturity dates, specified as scalar or an NINST-by-1 vector using a datetime array, string array, or date character vectors.

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

Period — Coupons per year

2 per year (default) | vector

(Optional) Coupons per year, specified as a scalar or an NINST-by-1 vector. Values for Period are 1, 2, 3, 4, 6, and 12.

Data Types: double

Basis — Day-count basis

0 (actual/actual) (default) | integer from 0 to 13

(Optional) Day-count basis, specified as scalar or an NINST-by-1 vector.

• 0 = actual/actual

• 1 = 30/360 (SIA)

• 2 = actual/360

• 3 = actual/365

• 4 = 30/360 (PSA)

• 5 = 30/360 (ISDA)

• 6 = 30/360 (European)

• 7 = actual/365 (Japanese)

• 8 = actual/actual (ICMA)

• 9 = actual/360 (ICMA)

• 10 = actual/365 (ICMA)

• 11 = 30/360E (ICMA)

• 12 = actual/365 (ISDA)

• 13 = BUS/252

For more information, see Basis.

Data Types: double

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

1 (in effect) (default) | nonnegative integer [0,1]

(Optional) End-of-month rule flag for generating dates when Maturity is an end-of-month date for a month having 30 or fewer days, specified as a scalar or a nonnegative integer [0, 1] using an NINST-by-1 vector.

• 0 = Ignore rule, meaning that a bond's coupon payment date is always the same numerical day of the month.

• 1 = Set rule on, meaning that a bond's coupon payment date is always the last actual day of the month.

Data Types: logical

IssueDate — Bond issue date

datetime array | string array | date character vector

(Optional) Bond issue date, specified as a scalar or an NINST-by-1 vector using a datetime array, string array, or date character vectors.

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

FirstCouponDate — Irregular first coupon date

datetime array | string array | date character vector

(Optional) Irregular first coupon date, specified as a scalar or an NINST-by-1 vector using a datetime array, string array, or date character vectors.

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

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

LastCouponDate — Irregular last coupon date

datetime array | string array | date character vector

(Optional) Irregular last coupon date, specified as a scalar or an NINST-by-1 vector using a datetime array, string array, or date character vectors.

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

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. If you do not specify a LastCouponDate, the cash flow payment dates are determined from other inputs.

StartDate — Forward starting date of payments

Settle date (default) | datetime array | string array | date character vector

Forward starting date of payments (the date from which a bond cash flow is considered), specified as a scalar or an NINST-by-1 vector using a datetime array, string array, or date character vectors.

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

If you do not specify StartDate, the effective start date is the Settle date.

Face — Face value

100 (default) | nonnegative value | cell array of nonnegative values

(Optional) Face or par value, specified as a scalar or an NINST-by-1 vector of nonnegative face values or an NINST-by-1 cell array of face values or face value schedules. For the latter case, each element of the cell array is a NumDates-by-2 cell array, where the first column is dates and the second column is its associated face value. The date indicates the last day that the face value is valid.

Data Types: cell | double

Output Arguments

InstSet — Variable containing a collection of instruments

structure

Variable containing a collection of instruments, returned as a structure. Instruments are broken down by type and each type can have different data fields. Each stored data field has a row vector or string for each instrument. For more information on the InstSet variable, see instget.

FieldList — Name of each data field for Bond instrument

cell array of character vectors

Name of each data field for a Bond instrument, returned as an NFIELDS-by-1 cell array of character vectors.

ClassList — Data class for each field

cell array of character vectors

Data class for each field, returned as an NFIELDS-by-1 cell array of character vectors. The class determines how arguments are parsed. Valid character vectors are 'dble', 'date', and 'char'.

TypeString — Type of instrument

character vector

Type of instrument, returned as a character vector. For a Bond instrument, TypeString = 'Bond'.

More About

Bond

A bond is a fixed-income financial instrument that represents a loan made by an investor to a borrower, typically a corporation or government.

In return for the loan, the borrower agrees to pay the bondholder periodic interest payments and to return the principal amount (the face value) of the bond at maturity.

Version History

Introduced before R2006a

R2022b: Serial date numbers not recommended

Although instbond 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.
