Subject 1. The Foreign Exchange Market
Let's say a:b = S.
- a is the price currency.
- b is the base currency.
- S is the cost of one unit of currency b in terms of currency a.
For example, US$ : £ = 1.5 indicates that £1 is priced at US$1.5.
The exchange rate above is referred to as the nominal exchange rate. The real exchange rate is the nominal rate adjusted somehow by inflation measures.
For example, if country A has an inflation rate of 10%, country B an inflation rate of 5%, and no changes in the nominal exchange rate took place, then country A now has a currency whose real value is higher than before.
Market Functions and Participants
A foreign exchange market is a place where foreign exchange transactions take place. Measured by average daily turnover, the foreign exchange market is by far the largest financial market in the world. It has important effects, either directly or indirectly, on the pricing and flows in all other financial markets.
There is a wide diversity of global FX market participants that have a wide variety of motives for entering into foreign exchange transactions. Commercial companies undertake FX transactions during cross-border purchases and sales of goods and services. Hedge funds trade FX currencies for hedging or even speculative purposes. Central banks use their FX reserves to stabilize the market and control the money supply. Large dealing banks provide FX price quotes to their clients. With so many different market participants, motives, and strategies, it is very difficult to describe the FX market adequately with simple characterizations.
