The Currency of Reference

In terms of volume, currencies around the world are traded mostly against the U.S. dollar, because the U.S. dollar is the currency of reference. The other major currencies are the euro, followed by the Japanese yen, the British pound, and the Swiss franc. Other currencies with significant spot market shares are the Canadian dollar and the Australian dollar.

The spot market is characterized by high liquidity and high volatility. Volatility is the degree to which the price of currency tends to fluctuate within a certain period of time. For instance, in an active global trading day (24 hours), the euro/dollar exchange rate may change its value 18,000 times "flying" 100-200 pips in a matter of seconds if the market gets wind of a significant event.

On the other hand, the exchange rate may remain quite static for extended periods of time, even in excess of an hour, when one market is almost finished trading and waiting for the next market to take over. For example, there is a technical trading gap between around 4:30 PM and 6 PM EDT. In the New York market, the majority of transactions occur between 8 AM and 12 PM, when the New York and European markets overlap.

The activity drops sharply in the afternoon, over 50 percent in fact, when New York loses the international trading support. Overnight trading is limited, as very few banks have overnight desks. Most of the banks send their overnight orders to branches or other banks that operate in the active time zones.
