This document discusses futures and options contracts for foreign exchange. It begins by explaining the key differences between futures contracts and forward contracts, noting that futures are standardized contracts that are traded on organized exchanges and involve daily mark-to-market settlement. It then provides details on major currency futures markets, contract specifications, and how to read futures quotes. The document also introduces currency options, describing call and put options, and discusses currency futures options which provide exposure to futures contracts.

9.1 Futures Contracts
A futures contract is like a forward contract:
It specifies that a certain currency will be exchanged for another at a
specified time in the future at prices specified today.
A futures contract is different from a forward contract:
Futures are standardized contracts trading on organized exchanges with daily
resettlement through a clearinghouse - marked to market.
Standardizing Features: contract size, delivery month, daily
resettlement - marked to market
Initial Margin: about 2-5 % of contract value, cash or T-bills held
in a street name at your brokers.
Participants’ losses or profits are realized daily instead of at
maturity as with a forward contract.
Because of marking to market, the futures price converges through
time to the spot price on the last day of trading in the contract.

Daily Resettlement = Marking to Market
Example: On Monday morning you take a long position in SF futures
contract that matures on Wednesday afternoon at $0.75/SF.
1. At the close of trading on Monday the futures price has risen to
$0.755. Because of the daily settlement you receive a cash profit of
$625 =125,000 x (0.755-0.75)
2. At Tuesday close the price has declined to $0.743. You must pay
the $1500 loss (125,000 x [0.743-0.755]) to the other side of the
contract.
3. At Wednesday close, the price drops to $0.74, and the contract
matures. You pay $375 loss to the other side and take the delivery
of the SF, paying the prevailing price of $0.74. You have a net loss
on the contract of $1250 (625-1500-375)
You can also close out your long position with an offsetting trade, if
you don’t want the delivery of the SF.

9.3 Basic Currency Futures Relationships
Open Interest refers to the number of contracts
outstanding for a particular delivery month.
Open interest is a good proxy for demand for a
contract.
Some refer to open interest as the depth of the
market. The breadth of the market would be how
many different contracts (expiry month, currency)
are outstanding.

Eurodollar futures prices are stated as an index number of three-
month LIBOR calculated as F = 100 – LIBOR.
The closing price for the July contract is 94.68 thus the implied yield
is 5.32 percent = 100 – 94.68
The change was .01 percent of $1 million representing $100 on an
annual basis. Since it is a 3-month contract one basis point
corresponds to a $25 price change.
