This example shows how to price a 4% fixedrate note using a set of zero curves by loading the file deriv.mat
, which provides ZeroRateSpec
, the interestrate term structure needed to price the note.
load deriv.mat CouponRate = 0.04; Settle = '01Jan2000'; Maturity = '01Jan2003'; Price = fixedbyzero(ZeroRateSpec, CouponRate, Settle, Maturity)
Price = 98.7159
Assume that a financial institution has an existing swap with three years left to maturity where they are receiving 5% per year in yen and paying 8% per year in USD. The reset frequency for the swap is annual, the principals for the two legs are 1200 million yen and $10 million USD, and both term structures are flat.
Settle = datenum('15Aug2015'); Maturity = datenum('15Aug2018'); Reset = 1; r_d = .09; r_f = .04; FixedRate_d = .08; FixedRate_f = .05; Principal_d = 10000000; Principal_f = 1200000000; S0 = 1/110;
Construct term structures.
RateSpec_d = intenvset('StartDate',Settle,'EndDate',Maturity,'Rates',r_d,'Compounding',1); RateSpec_f = intenvset('StartDate',Settle,'EndDate',Maturity,'Rates',r_f,'Compounding',1);
Use fixedbyzero:
B_d = fixedbyzero(RateSpec_d,FixedRate_d,Settle,Maturity,'Principal',Principal_d,'Reset',Reset); B_f = fixedbyzero(RateSpec_f,FixedRate_f,Settle,Maturity,'Principal',Principal_f,'Reset',Reset);
Compute swap price. Based on Hull (see References), a cross currency swap can be valued with the following formula V_swap
= S0*B_f
− B_d
.
V_swap = S0*B_f  B_d
V_swap = 1.5430e+06
RateSpec

'EndMonthRule'
— Endofmonth rule flag for generating dates when Maturity
is endofmonth date for month having 30 or fewer days1
(in effect) (default)  nonnegative integer [0,1]
Endofmonth rule flag for generating dates when Maturity
is an
endofmonth date for a month having 30 or fewer
days, specified as the commaseparated pair
consisting of 'EndMonthRule'

= Ignore rule, meaning
that a payment date is always the same numerical
day of the month.

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.

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.

A fixedrate note is a longterm debt security with a preset interest rate and maturity, by which the interest must be paid.
The principal may or may not be paid at maturity. In Financial Instruments Toolbox™, the principal is always paid at maturity. For more information, see FixedRate Note.
