The foreign exchange market has evolved extensively over time, undergoing important shifts in the types of market participants and the mix of instruments traded, within a trading ecosystem that has become increasingly complex. In this post, we discuss fundamental changes in this market over the past twenty-five years and highlight some of the implications for its future evolution. Our analysis suggests that maintaining a healthy price discovery process and fostering a level playing field among participants are areas to watch for challenges. The consequences of the evolution of the FX market—well beyond those anticipated twenty-five years ago—remain active areas of research and policy consideration.
Evolving Size, Instruments, and Currency Composition
In 1998, when flexible exchange rates had been in place for twenty-five years, the definitive guide to how the FX market operated—“All About The Foreign Exchange Market in the United States”—was written by Sam Cross, at that time the Executive Vice President of the Foreign Department at the Federal Reserve Bank of New York. The FX market has grown substantially in the last twenty-five years since that publication, and it continues to be the largest financial market in the world by trading volume. Average daily turnover increased from $1.5 to $7.5 trillion between 1998 and 2022 (BIS 2022), with the increase occurring across both FX spot and FX derivatives. Over the past ten years, however, FX spot trading volume has stagnated, while much of the growth has come from activity in FX swaps, instruments used primarily for funding and hedging. The growth in FX swap turnover owes in part to the shortening in maturity of these instruments, as they now have to be rolled over more frequently.
