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.
