A commercial bank has fixed-rate, long term loans in its asset portfolio and variable-rate CDs in its liability portfolio. Bank managers believe interest rates will increase in the future. What side of a fixed-floating rate swap would the commercial bank need to take to protect against this interest rate risk?
Bank would pay fixed and receive floating. The bank would earn fixed rate on its assets but would have to pay variable rates on its' liabilities. Bank would want to protect against this. Bank would want to receive variable or floating and pay fixed. Basically what the bank would receive from the loan, it would pass on to the counterparty of the swap and what it would receive from swap would pass on on to the CD investors. Here in, the spread over LIBOR it would receive in swap compared to the spread over LIBOR it would pay to the CD investor, and fixed rate it would receive from loan compared to the fixed rate it would pay in the swap would determine net profit/loss

What are the differences between a cap, a floor, and a collar? When would a firm enter any of these derivative security positions?
Cap- actually a limitation just like a stop loss. It creates a maximum limit say for interest rate so that higher interest liability can be avoided. EX: if a person has taken a loan on floating rates of LIBOR and he buys a cap for 5%, then if the interest rate increases above 5%, he will get the amount equal to excess paid by him above 5% Floor- sets a base level interest rate. It is the least rate of interest that the lender will expect to earn in case of failing interest rates EX: Lender lends to LIBOR and buys a floor of 3.5%. If LIBOR falls below 3.5%, the lender will receive the balance amount from the seller of the floor, making his effective interest earning approx. equals 3.5% Collar- mix of cap and floor. It includes the feature of both the cap and floor. The investor can fix the higher limit as well as the lower limit. This will create a band or say a range within which the interest rate will fluctuate. Using this, high fluctuation can be avoided A firm would enter into these derivative securities when there is a high level of uncertainty or fluctuations in the interest rate market. These derivatives will work as an effective hedge against the flux's in the interest rates.
What are the three ways on option holder can liquidate his or her position?
Closing Position- Once the option contract is bought or sold, the trader can hold the contract till maturity. If the trader wants to get out of the position before maturity he or she will square off the position by closing the contract before the expiry period. Exercise- Exercising option means buying or selling the underlying asset of the option contract. It means exercising the right to buy or sell the contract on the expiry day Expire- On mentioned expiry date, if the option contract is not exercised and is still with the holder of the contract, it is considered as an expired contract. On expiry the left over value of the contract is transferred to buyer's account and the seller has to pay the amount. Most of the option contracts are closed by the traders rather than exercising or waiting till expiry. Few contracts are actually excerised.

Currency swap has the following main uses: -to buy debt at cheaper rate -to hedge against exchange rate flux's -to convert a liability in one currency to other currency -to convert an asset in one currency to other currency Thus, the American firm will convert the fixed rate liability to floating rate liability by swapping the contract. Hence, the American firm will take the Fixed for-Floating currency swap to protect itself from the floating rate risk
What is a derivative security
Derivative Security- a financial instrument whose value is derived from the value of the underlying asset. Futures, forwards, options and swaps are some common types of derivative instruments. They are one of the important components of the financial system.

In derivatives markets, the sale and purchase of shares are able to be settled on a future date and there is only a contract executed in the current. Therefore if a client occurs loss at the future date there may arise a situation of default of non-payment. To curb these stock exchanges have certain regulations related to margin. There are two types of margin that are deducted from the account of the traders when they enter into a future or options transactions( initial margin and maintenance margin) Initial Margin- Post only a portion of the value of the futures(and options) contracts any time they request a trade. Minimum margin levels are set by each exchange. Maintenance Margin- The margin a futures trader must maintain once a futures position is taken. If losses on the customer's futures position occur and level of the funds in the margin account drop below the maintenance margin, a customer is required to deposit additional funds into his margin account, bringing the balance back up to the initial margin.
