This example shows how to compute the cash flows for a CMS instrument.

Create CMS Instrument Object

Use fininstrument to create a CMS instrument object.

Settle = datetime(2022,9,15);
Maturity = datetime(2028,9,15);
CMSLegPeriod = 2;
FixedLegPeriod = 2;

CMSInstrument = fininstrument("CMS",Maturity=datetime(2028,9,15),CMSReferenceTenor=10,Reset=[CMSLegPeriod FixedLegPeriod],LegRate=[0 0.01],LegType=["cms" "fixed"],Name="CMS instrument")
CMSInstrument = 
  CMS with properties:

           CMSReferenceReset: 2
           CMSReferenceTenor: 10
                     LegRate: [0 0.0100]
                     LegType: ["cms"    "fixed"]

Compute Cash Flows

Create the CMSRateTimeTable using cfdates with Settle and Matrurity values.

Time = [Settle;cfdates(Settle,Maturity,CMSLegPeriod)'];
CMSRates = [0.0216 0.0216 0.0231 0.0246 0.0262 0.0279 ...

Input Arguments

collapse all

Instrument object, specified using a previously created instrument object for one of the following: CMS or CMSNote.

Note

If the InstrumentObject is a vector of instruments, you must use CMSCashflows separately with each instrument.

Data Types: object

Settlement date, specified as a scalar datetime value, string, or date character vector. The Settle date must be before the Maturity date for the CMS or CMSNote instrument.

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

CMS rate timetable, specified as CMSRateTimeTable and a timetable with the following columns:

  • Time — NumCashFlows-by-1 cash flow dates in datetime format in the first column of the timetable

  • CMSRates — NumCashFlows-by-1 CMS rates in decimals

Data Types: timetable

Output Arguments

collapse all

Cash flow for underlying asset (InstrumentObject), returned as a timetable.

Note

To compute outCF for float legs for a CMS instrument, you must specify a ProjectionCurve name-value argument when creating the CMS instrument object.
