A foreign exchange (FX) transaction is a transaction which
allows funds to flow between bank deposits denominated in
different currencies.
Last available figures from the
Bank for International Settlements (BIS) show that on an
average day, over $1.9 trillion changed hands in the 24 hour
global FX marketplace.
Surprisingly, only about 15% of FX is directly driven by
cross-border trade in goods and services. Approximately 85% is
driven by capital transactions conducted by banks for financial
engineering and speculation.
Each sovereign state issues and manages its own currency
through a national central bank. The exception is the
eurozone. This new currency area is made up of 12 European
Member States. A politically independent
European Central Bank issues and manages the trans-national
currency, the
euro.
The euro should not be confused with
eurocurrencies, which are currencies held in deposits
outside their national banking system.
For example, dollars held in the account of a German bank are
known as eurodollars, yen held in the account of a London bank
- and as an asset of the London bank - are known as euroyen,
and so on.
Terminology
In the markets, currency names are shortened to 3 letters to
meet the needs of screen-based tables. These were developed by
the International Organisation for Standardisation and are
called ISO codes or
SWIFT codes. We use these conventions throughout.
The currencies in purple are the 'legacy' national currency
units (NCUs) which represented localised denominations of a
single currency, the euro. They were tradeable as NCUs until
1.01.2002 when the euro became the sole denomination.
Interbank fund flows are predominantly in euro because pricing,
trading and settlement in all
EMU money, debt and equity markets are now denominated
solely in euro.
