tfutimprepo

Implied repo rates for Treasury bond future given price

Syntax

ImpliedRepo = tfutimprepo(ReinvestData,Price,QtdFutPrice,Settle,MatFut,ConvFactor,CouponRate,Maturity)

Description

ImpliedRepo = tfutimprepo(ReinvestData,Price,QtdFutPrice,Settle,MatFut,ConvFactor,CouponRate,Maturity) computes the implied repo rate that prevents arbitrage of Treasury bond futures, given the clean price at the settlement and delivery dates.

Examples

Compute the Implied Repo Rates for Treasury Bond Futures Given the Price

This example shows how to compute the implied repo rate given the following set of data.

ReinvestData = [0.018  3];
Price = [114.4160; 113.1710];
QtdFutPrice = [114.1201; 113.7090];
Settle = datenum('11/15/2002'); 
MatFut = [datenum('15-Dec-2002'); datenum('15-Mar-2003')];
ConvFactor = [1; 0.9854];
CouponRate = [0.06; 0.0575];
Maturity = [datenum('15-Aug-2009'); datenum('15-Aug-2010')];
 
ImpliedRepo = tfutimprepo(ReinvestData, Price, QtdFutPrice, ...
Settle, MatFut, ConvFactor, CouponRate, Maturity)

ImpliedRepo = 2×1

    0.0200
    0.0200

Input Arguments

ReinvestData — Reinvestment of intervening coupons

matrix

Reinvestment of intervening coupons, specified as a number of futures NFUT-by-2 matrix of rates and bases in the form of [ReinvestRate ReinvestBasis].

ReinvestRate is the simple reinvestment rate, in decimal. Specify ReinvestBasis as 0 = not reinvested, 2 = actual/360, or 3 = actual/365.
