B1. Currency Forwards  The exchange of one currency for another at a future date using a pre-determined exchange rate  At inception, the two parties—long and short—simply agree on the forward price.  At maturity, the short delivers the contracted units of the base currency and in return the long makes payment using the terms currency.  Certain currency forwards do not entail actual delivery of the foreign currency and are known as non-deliverable forwards (NDF). 3-5

B2. Forward Price and Forward Premium  Price is calculated using the following equation:  Premium (or discount) is calculated as follows: 3-6

B3. Forward Pricing Example  S = (INRUSD)  r = 5% (US interest rate)  r* = 10% (Indian interest rate)  t = 2 (years) 3-7

B4. Currency Futures  A currency futures contract is an exchange traded version of the currency forward contract.  Futures are standardized. For instance, the GBP futures traded in the Chicago Mercantile Exchange has very specific maturities (every 3 months) and size (62,500 currency units).  Futures may be priced using the forward pricing equation since futures and forwards are very similar instruments. 3-8

B4. Currency Futures (cont.)  Daily settlement of profits and losses in margin accounts eliminates counterparty risk  The CME lists more than 20 futures contracts in various currencies, cross- currencies and currency indexes. This list includes the major currencies—JPY, GBP, EUR and CHF—as well as emerging markets currencies such as the Chinese Renminbi, South African Rand and the Russian Ruble (CNY, ZAR and RUB respectively). 3-9

C1. Currency Options  Provides the right but not the obligation to purchase (or sell) the underlying or base currency at a future date at a pre-specified strike price denominated in the terms currency.  Options may be calls (allowing purchase) or puts (allowing sale).  Unlike forwards and futures, an option may only be acquired by paying a premium.  Currency options are traded in the PHLX and CME. 3-10
