Safe Investments - Risks by the foreign exchange on Forex

As it was mentioned above trading on the Forex is essentially risk-bearing. By the evaluation of the grade of a possible risk accounted should be the following kinds of it: exchange rate risk, interest rate risk, and credit risk, country risk.

Exchange rate risk is the effect of the continuous shift in the worldwide market supply and demand balance on an outstanding foreign exchange position. For the period it is outstanding, the position will be subject to all the price changes. The most popular measures to cut losses short and ride profitable positions that losses should be kept within manageable limits are the position limit and the loss limit. By the position limitation a maximum amount of a certain currency a trader is allowed to carry at any single time during the regular trading hours is to be established. The loss limit is a measure designed to avoid unsustainable losses made by traders by means of stop-loss levels setting.

Interest rate risk refers to the profit and loss generated by fluctuations in the forward spreads, along with forward amount mismatches and maturity gaps among transactions in the foreign exchange book. This risk is pertinent to currency swaps; forward outright, futures, and options (See below). To minimize interest rate risk, one sets limits on the total size of mismatches. 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 dates of the delivery, gains and losses. Continuous analysis of the interest rate environment is necessary to forecast any changes that may impact on the outstanding gaps.

Credit risk refers to 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, such as the clearinghouse of Chicago. The following forms of credit risk are known:

1. Replacement risk occurs when counterparties of the failed bank find their books are subjected to the danger not to get refunds from the bank, where appropriate accounts became unbalanced.
2. Settlement risk occurs because of the time zones on different continents. Consequently, currencies may be traded at the different price at different times during the trading 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.

Therefore, in assessing the credit risk, end users must consider not only the market value of their currency portfolios, but also the potential exposure of these portfolios. The potential exposure may be determined through probability analysis over the time to maturity of the outstanding position. The computerized systems currently available are very useful in implementing credit risk policies. Credit lines are easily monitored. In addition, the matching systems introduced in foreign exchange since April 1993 are used by traders for credit policy implementation as well. Traders input the total line of credit for a specific counterparty. During the trading session, the line of credit is automatically adjusted. If the line is fully used, the system will prevent the trader from further dealing with that counterparty. After maturity, the credit line reverts to its original level.

Kinds of the Forex
Spot Market. Currency spot trading is the most popular foreign currency instrument around the world, making up 37 percent of the total activity (See Figure 1.2). The features of the fast-paced spot market are high volatility and quick profits (as well losses).

A spot deal consists of a bilateral contract whereby a party delivers a specified amount of a given currency against receipt of a specified amount of another currency from counterparty, based on an agreed exchange rate, within two business days of the deal date. The exception is the Canadian dollar, in which the spot delivery is executed next business day. The two-day spot delivery for currencies was developed long before technological breakthroughs in information processing. This time period was necessary to check out all transactions' details among counterparties. Although technologically feasible, the contemporary markets did not find it necessary to reduce the time to make payments. Human errors still occur and they need to be fixed before delivery. By the entering into a contract on the spot market a bank serving a trader tells the latter the quota - an evaluation of the currency traded against the U.S. dollar or another currency. A quota consists of two figures (for example, USD/JPY = 133.27/133.32 or USD/JPY = 133.27/32 which means the same). The first of these figures (the left part) is called the bid - price (that is a price at which the trader sells), the second (the right part) is called the ask - price (the price at which the trader buys the currency). The difference between asks and bid is called the spread. The spread, as any currency price alteration, is being measured in points (pips).

In terms of volume, currencies around the world are traded mostly against the U.S. dollar, because the U.S. dollar is the currency of reference. The other major currencies are the euro, followed by the Japanese yen, the British pound, and the Swiss franc. Other currencies with significant spot market shares are the Canadian dollar and the Australian dollar. In addition, a significant share of trading takes place in the currencies crosses, a non-dollar instrument whereby foreign currencies are quoted against other foreign currencies, such as euro against Japanese yen. The spot market is characterized by high liquidity and high volatility. Volatility is the degree to which the price of currency tends to fluctuate within a certain period of time. For instance, in an active global trading day (24 hours), the euro/dollar exchange rate may change its value 18,000 times "flying" 100-200 pips in a matter of seconds if the market gets wind of a significant event.

On the other hand, the exchange rate may remain quite static for extended periods of time, even in excess of an hour, when one market is almost finished trading and waiting for the next market to take over. For example, there is a technical trading gap between around 4:30 PM and 6 PM EDT. In the New York market, the majority of transactions occur between 8 AM and 12 PM, when the New York and European markets overlap. The activity drops sharply in the afternoon, over 50 percent in fact, when New York loses the international trading support. (See Figure 1.3) Overnight trading is limited, as very few banks have overnight desks. Most of the banks send their overnight orders to branches or other banks that operate in the active time zones. Reasons for the popularity of the spot-market include the rapid liquidity, thanks to the market volatility, and short term contract execution. Therefore, the credit risk is restricted. The profit and loss can be either realized or unrealized. The realized P&L is a certain amount of money netted when a position is closed. The unrealized P&L consists of an uncertain amount of money that an outstanding position would roughly generate if it were closed at the current rate. The unrealized P&L changes continuously in tandem with the exchange rate.
