  1. Use fininstrument to create a FloatBond instrument object.

  2. Use ratecurve to specify a curve model for the FloatBond instrument.

  3. Use finpricer to specify a Discount pricing method for the FloatBond instrument.

For more 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 FloatBond instrument, see Choose Instruments, Models, and Pricers.

Creation

Syntax

FloatBondObj = fininstrument(InstrumentType,'Spread',spread_value,'Maturity',maturity_date)
FloatBondObj = fininstrument(___,Name,Value)

Description

example

FloatBondObj = fininstrument(InstrumentType,'Spread',spread_value,'Maturity',maturity_date) creates a FloatBond object by specifying InstrumentType and sets the properties for the required name-value pair arguments Spread and Maturity.

The FloatBond instrument supports a vanilla floating rate note and an amortizing floating rate note. For more information, see Floating-Rate Note.

example

FloatBondObj = fininstrument(___,Name,Value) sets optional properties using additional name-value pairs in addition to the required arguments in the previous syntax. For example, FloatBondObj = fininstrument("FloatBond",'Spread',0.6,'Maturity',datetime(2019,1,30),'Basis',1,'Principal',100,'FirstCouponDate',datetime(2016,1,30),'EndMonthRule',true,'Name',"float_bond_instrument") creates a FloatBond instrument with a spread of 0.6 and a maturity of January 30, 2019. You can specify multiple name-value pair arguments.

Input Arguments

expand all

Instrument type, specified as a string with the value of "FloatBond" or a character vector with the value of 'FloatBond'.

Data Types: char | string

FloatBond Name-Value Pair Arguments

Specify required and optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: FloatBondObj = fininstrument("FloatBond",'Spread',0.6,'Maturity',datetime(2019,1,30),'Basis',1,'Principal',100,'FirstCouponDate',datetime(2016,1,30),'EndMonthRule',true,'Name',"float_bond_instrument")
Required FloatBond Name-Value Pair Arguments

expand all

Decimal value over the reference rate, specified as the comma-separated pair consisting of 'Spread' and a scalar nonnegative decimal.

Data Types: double

Maturity date, specified as the comma-separated pair consisting of 'Maturity' and a scalar datetime, serial date number, date character vector, or date string.

If you use a date character vector or date string, the format must be recognizable by datetime because the Maturity property is stored as a datetime.

Data Types: char | double | string | datetime

Optional FloatBond Name-Value Pair Arguments

expand all

Frequency of payments per year, specified as the comma-separated pair consisting of 'Reset' and a scalar integer. Values for Reset are: 1, 2, 3, 4, 6, or 12.

Data Types: double

Day count basis, specified as the comma-separated pair consisting of 'Basis' and a scalar integer using one of the following values:

  • 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

Notional principal amount or principal value schedule, specified as the comma-separated pair consisting of 'Principal' and a scalar numeric or timetable.

Principal accepts a timetable, where the first column is dates and the second column is the associated notional principal value. The date indicates the last day that the principal value is valid.

Data Types: double | timetable

Rate curve for projecting floating cash flows, specified as the comma-separated pair consisting of 'ProjectionCurve' and a ratecurve object. You must create this object using ratecurve.

Data Types: object

Lag in rate setting, specified as the comma-separated pair consisting of 'ResetOffset' and a scalar numeric.

Data Types: double

Latest floating rate for the FloatBond object, specified as the comma-separated pair consisting of 'LatestFloatingRate' and a scalar decimal.

Data Types: double

Flag to adjust cash flows based on actual period day count, specified as the comma-separated pair consisting of 'DaycountAdjustedCashFlow' and a scalar logical with a value of true or false.

Data Types: logical

Business day conventions, specified as the comma-separated pair consisting of 'BusinessDayConvention' and a scalar string or character vector. 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 | string

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

H = holidays(datetime('today'),datetime(2025,12,15));
FloatBondObj = fininstrument("floatbond",'Spread',100,'Maturity',datetime(2025,12,15),'Holidays',H)

Data Types: double | cell | datetime | string

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 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

Bond issue date, specified as the comma-separated pair consisting of 'IssueDate' and a scalar datetime, serial date number, date character vector, or date string.

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

Data Types: double | char | string | datetime

Irregular first coupon date, specified as the comma-separated pair consisting of 'FirstCouponDate' and a scalar datetime, serial date number, date character vector, or date string.

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 a date character vector or date string, the format must be recognizable by datetime because the FirstCouponDate property is stored as a datetime.

Data Types: double | char | string | datetime

Irregular last coupon date, specified as the comma-separated pair consisting of 'LastCouponDate' and a scalar datetime, serial date number, date character vector, or date string.

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 a date character vector or date string, the format must be recognizable by datetime because the LastCouponDate property is stored as a datetime.

Data Types: double | char | string | datetime

Forward starting date of payments, specified as the comma-separated pair consisting of 'StartDate' and a scalar datetime, serial date number, character vector, or date string.

If you use a date character vector or date string, the format must be recognizable by datetime because the StartDate property is stored as a datetime.

Data Types: char | double | string | datetime

User-defined name for the instrument, specified as the comma-separated pair consisting of 'Name' and a scalar string or character vector.

Data Types: char | string
