Interest Rate Risk
Interest rate risk is pertinent to currency swaps, forward out rights, futures, and options. It refers to the profit and loss generated by both the fluctuations in the forward spreads and by forward amount mismatches and maturity gaps among transactions in the foreign exchange book. An amount mismatch is the difference between the spot and the forward amounts. For an active forward desk the complete elimination of maturity gaps is virtually impossible. However, this may not be a serious problem if the amounts involved in these mismatches are small. On a daily basis, traders balance the net payments and receipts for each currency through a special type of swap, called tomorrow/next or rollover.
To minimize interest rate risk, management sets limits on the total size of mismatches. The policies differ among banks, but a common approach is to separate the mismatches, based on their maturity dates, into up to six months and past six months. All the transactions are entered in computerized systems in order to calculate the positions for all the delivery dates and the profit and loss. Continuous analysis of the interest rate environment is necessary to forecast any changes that may impact on the outstanding gaps.
Credit Risk
Credit risk is connected with the possibility that an outstanding currency position may not be repaid as agreed, due to a voluntary or involuntary action by a counter party. In these cases, trading occurs on regulated exchanges, where all trades are settled by the learing house. On such exchanges, traders of all sizes can deal without any credit concern.
The following forms of credit risk are known:
1. Replacement risk which occurs when counter parties of the failed bank find their books unbalanced to the extent of their exposure to the insolvent party. To rebalance their books, these banks enter new transactions.
2. Settlement risk which occurs because of different time zones on different continents. Such a way, currencies may be credited at different times during the day. Australian and New Zealand dollars are credited first, then Japanese yen, followed by the European currencies and ending with the U.S. dollar. Therefore, payment may be made to a party that will declare insolvency (or be declared insolvent) immediately after, but prior to executing its own payments.
The credit risk for instruments traded off regulated exchanges is to be minimized through the customers' creditworthiness. Commercial and investment banks, trading companies, and banks' customers must have credit lines with each other to be able to trade. Even after the credit lines are extended, the counter parties financial soundness should be continuously monitored. Along with the market value of their currency portfolios, end users, in assessing the credit risk, must consider also the potential portfolios exposure. The latter may be determined through probability analysis over the time to maturity of the outstanding position. For the same purposes netting is used. Netting is a process that enables institutions to settle only their net positions with one another not trade by trade but at the end of the day, in a single transaction. If signs of payment difficulty of a bank are shown, a group of large banks may provide short-term backing from a common reserve pool.
