Foreign Exchange Investing

Foreign exchange (forex or FX) markets form the core of the global financial market, a seamless twenty-four hour structure dominated by sophisticated professional players commercial banks, central banks, hedge funds and forex brokers and often extremely volatile. Many investors, particularly American ones, tend to ignore currency movements, and few financial analysts are trained to analyze the details of forex markets. But this is a mistake. As the 1997 Asian crisis and its aftermath vividly reveal, foreign exchange these days tends to lead economic activity. And the foreign exchange markets are huge, growing and increasingly powerful.

According to the Bank for International Settlements, the central bank for central banks, average daily turnover on the world's foreign exchange markets reached almost $1,500 billion ($1.5 trillion) in April 1998, 26% higher than when it last measured forex flows in 43 different countries three years earlier. Transactions in-volving dollars on one side of the trade accounted for 87% of that forex business. Almost a third of all forex trading takes place in London, by far the world's largest center, with New York and To-kyo second and third. Although London forex trading grew more slowly than New York over the three years to 1998, its average daily turnover remains greater than New York and Tokyo combined, having risen from $464 billion to $637 billion.

To put these figures in perspective, daily trading volume on the New York Stock Exchange (NYSE) is only about $20 billion; activity in short-term US government securities is around ten times that at $200 billion; and so at $1,500 billion, foreign exchange trading is seven and a half times the volume of trading in short-term US government securities and seventy-five times NYSE trading. This volume is far greater than the size of foreign currency reserves held by any single country. The forex markets cannot be ignored: for their size and forecasting ability; and for the potential that developments in these markets have for the future of the dollar as the world's dominant currency.

In the past, trading in the real economy controlled relative currency relationships. Since most currency flows were to settle trading patterns, there was a balance as goods and capital moved at about the same speed. But now the leads and lags are the other way around. While in name, forex markets exist to facilitate international trade, in practice, the bulk of turnover in these markets is attributable to speculation. Because financial flows are many times the size of trade flows and because financial flows are nearly instantaneous, currency market levels now tend to set trade: if a country's currency becomes low relative to others, domestic producers find it easier to export. The market sets the economy.
