With the huge growth in world trade over the last few decades, companies increasing-
ly deal, as buyer, seller or investor, in foreign currency, making it a key factor in finan-
cial management. For competitive reasons, exporters are commonly obliged to invoice
in the customer’s currency – in 2001, the Customs and Excise (www.hmce.gov.uk)
reported that 50 per cent of UK exports were invoiced in foreign currencies (and, sur-
prisingly, 60 per cent of imports).
Foreign currency can change in value relative to the home currency to significant
degrees over a short time.
Table 21.1 and Figure 21.1 illustrate changes of the exchange rate of sterling against
other currencies. The data in Table 21.1 are the average of daily Telegraphic Transfer
rates in London. The charts on Figure 21.1 are based on a log scale.
Such changes can seriously undermine the often wafer-thin profit margin of a trad-
er awaiting payment in foreign currency. If sterling appreciates, the sterling value of
the deal can evaporate before its eyes, while the likelihood of repeat business dimin-
ishes unless it lowers price, i.e. takes a smaller profit margin in sterling terms. It is easy
to understand the concern of a major exporter like VW, a great proportion of whose
export trade is priced in dollars.
In this chapter, we explain the theory of foreign exchange markets and how they
work in practice, and how exporters and importers can protect themselves against the
risks of foreign exchange rate variations. There are two key issues for the treasurer of
a company with significant foreign trading links to address:
1 Whether to seek protection against these variations, i.e. to ‘hedge’, or to ride the risks,
on the basis that in the long-term they will even out. Most companies do seek
hedges, being risk-averters. Yet some actively seek out foreign exchange risk, and
use dealing opportunities as a source of profit by deliberately taking ‘positions’ in
particular currencies. BP plc (www.bp.com) for example, exploits its position as a
multinational with a substantial two-way flow in several currencies to operate its
currency dealing activity as a separate profit centre. Such companies are called
‘speculators’.
2 The second issue concerns the extent to which the firm wants to hedge – whether to
totally avoid exposure to exchange rate risk or to control the degree of exposure.
The policy of the Anglo-Dutch steel group Corus plc (www.corusgroup.com) is
clear. It states in its 2004 Annual Report, ‘It is the group’s policy that substantial-
ly all of the net currency transaction exposure arising from contracted sales and
