intenvprice

Price instruments from set of zero curves

Syntax

Price = intenvprice(RateSpecInstSet)

Description

Price = intenvprice(RateSpecInstSet) computes arbitrage-free prices for instruments against a set of zero coupon bond rate curves.

intenvprice handles the following instrument types: 'Bond', 'CashFlow', 'Fixed', 'Float', 'Swap'. See instadd for information about constructing defined types.

Examples

Load Zero Curves and Instruments from Data File

Load the zero curves and instruments.

Create a Float-Float Swap and Price with intenvprice

Use instswap to create a float-float swap and price the swap with intenvprice.

RateSpec = intenvset('Rates',.05,'StartDate',today,'EndDate',datemnth(today,60));
IS = instswap([400 200],today,datemnth(today,60),[], [], [], [0 0]);
intenvprice(RateSpec,IS)

ans = 8.6440

Create Float-Float, Fixed-Fixed, and Float-Fixed Swaps and Price with intenvprice

Use instswap to create swaps and price the swaps with intenvprice.

RateSpec = intenvset('Rates',.05,'StartDate',today,'EndDate',datemnth(today,60));
IS = instswap([.03 .02],today,datemnth(today,60),[], [], [], [1 1]);
IS = instswap(IS,[200 300],today,datemnth(today,60),[], [], [], [0 0]);
IS = instswap(IS,[300 .07],today,datemnth(today,60),[], [], [], [0 1]);
intenvprice(RateSpec,IS)

ans =

Input Arguments

RateSpec — Interest-rate specification

structure

(Optional) Interest-rate specification, specified by the RateSpec obtained previously from intenvset or toRateSpec for an IRDataCurve or toRateSpec for an IRFunctionCurve.

Data Types: struct

InstSet — Instrument variable containing a collection of instruments

structure

Instrument variable containing a collection of instruments, specified using instadd. Instruments are categorized by type; each type can have different data fields. The stored data field is a row vector or character vector for each instrument.

Data Types: struct

Output Arguments

Price — Prices of each instrument

matrix

Prices of each instrument, returned as a number of instruments (NINST) by number of curves (NUMCURVES) matrix. If an instrument cannot be priced, a NaN is returned in that entry.
