## FX Forward Valuation Calculator

## FX forward example

- trade date : 1/oct/2012
- maturity date: 1/oct/2013

on maturity date A will buy 100 USD at exchange rate EURUSD 1.23

## FX forward pricing

### What market data do we need?

- forward points
- EUR discount curve

Forward points for 1 month represent how many basis points to add to current spot to know the forward EURUSD exchange rate

(for valuation date of today could be found on page fxstreet)

for example if forward points for EURUSD for 1 month is 30 and eurusd spot for valuation date is 1.234 then

the forward rate EURUSD for valuation date+ 1 month would be $$1.234+30/10000=1.237$$

## FX forward valuation algorithm

- calculate forward exchange rate in euros: Forward in dollars=spot+Forwardpoints/10000 , Forward in Euros=1/ForwardInDollars
- caclulate net value of transaction at maturity: NetValue=Nominal*(Forward-Strike)
- discount it to valuation date with EUR discount curve: NPV=DiscountFactorEUR(maturity)*NetValue

## FX forward example valuation:

valuation date: 1/oct/2012

### market data:

forward FX points EURUSD 12months = 100

discount factor EUR (1/oct/2013) = 0.9

Spot EURUSD (1/oct/2012) = 1.234

### 1) calculate FX Forward for 12 months maturity:

Forward 12m EURUSD=1.234+100/10000 = 1.244

Forward USDEUR = 1/1.244=0.8039

### 2) calculate value at maturity:

strike in EUR = 1/1.23 = 0.813

Value(maturity)=100 (0.8039-0.813)=-0.91496 EUR

### 3) descount value to valuation date

NPV= 0.9*(-0.91496)=-0.82346 EUR
