CHAPTER 2
Futures Markets and Central Counterparties
Practice Questions
Problem 2.1.
sql索引字段Distinguish between the terms open interest and trading volume.
The open interest of a futures contract at a particular time is the total number of long positions outstanding. (Equivalently, it is the total number of short positions outstanding.) The trading volume during a certain period of time is the number of contracts traded during this periodposition of the day.
Problem 2.2.
汉译英翻译器在线翻译What is the difference between a local and a futures commission merchant?
A futures commission merchant trades on behalf of a client and charges a commission. A local trades on his or her own behalf.
Problem 2.3.
Suppose that you enter into a short futures contract to sell July silver for $17.20 per ounce. The size of the contract is 5,000 ounces. The initial margin is $4,000, and the maintenance margin is $3,000. What change in the futures price will lead to a margin call? What happens if you do not meet the margin call?
There will be a margin call when $1,000 has been lost from the margin account. This will occur when the price of silver increases by 1,000/5,000 $0.20. The price of silver must therefore rise to $17.40 per ounce for there to be a margin call. If the margin call is not met, your broker closes out your position.
Problem 2.4.
Suppose that in September 2018 a company takes a long position in a contract on May 2简单网页设计html
019 crude oil futures. It closes out its position in March 2019. The futures price (per barrel) is $48.30 when it enters into the contract, $50.50 when it closes out its position, and $49.10 at the end of December 2018. One contract is for the delivery of 1,000 barrels. What is the company’s total profit? When is it realized? How is it taxed if it is (a) a hedger and (b) a speculator? Assume that the company has a December 31 year-end.
The total profit is ($50.50 $48.30) 1,000 $2,200. Of this ($49.10 $48.30) 1,000  or $800 is realized on a day-by-day basis between September 2018 and December 31, 2018. A further ($50.50 $49.10) 1,000  or $1,400  is realized on a day-by-day basis between January 1, 2019, and March 2019. A hedger would be taxed on the whole profit of $2,200 in 2019. A speculator would be taxed on $800 in 2018 and $1,400 in 2019.
Problem 2.5.
What does a stop order to sell at $2 mean? When might it be used? What does a limit order to sell at $2 mean? When might it be used?
A js截取前10个字符串stop order to sell at $2 is an order to sell at the best available price once a price of $2 or less is reached. It could be used to limit the losses from an existing long position. A limit order to sell at $2 is an order to sell at a price of $2 or more. It could be used to instruct a broker that a short position should be taken, providing it can be done at a price at least as favorable as $2.
Problem 2.6.
What is the difference between the operation of the margin accounts administered by a clearing house and those administered by a broker?
The margin account administered by the clearing house is marked to market daily, and the clearing house member is required to bring the account back up to the prescribed level daily. The margin account administered by the broker is also marked to market daily. However, the account does not have to be brought up to the initial margin level on a daily basis. It has to be brought up to the initial margin level when the balance in the account falls below the maintenance margin level. The maintenance margin is usually about 75%
of the initial margin.
Problem 2.7.
What differences exist in the way prices are quoted in the foreign exchange futures market, the foreign exchange spot market, and the foreign exchange forward market?
In futures markets, prices are quoted as the number of U.S. dollars per unit of foreign currency. Spot and forward rates are quoted in this way for the British pound, euro, Australian dollar, and New Zealand dollar. For other major currencies, spot and forward rates are quoted as the number of units of foreign currency per U.S. dollar.

The party with a short position in a futures contract sometimes has options as to the precise asset that will be delivered, where delivery will take place, when delivery will take place, and so on. Do these options increase or decrease the futures price? Explain your reasoning.
These options make the contract less attractive to the party with the long position and more attractive to the party with the short position. They therefore tend to reduce the futures price.
