[email protected] [email protected] Sizing up global foreign exchange markets1 The latest BIS Triennial Survey shows that global foreign exchange trading increased to more than $6 trillion per day. Trading bounced back strongly following a dip in 2016, buoyed by increased trading with financial clients such as lower-tier banks, hedge funds and principal trading firms. Prime brokerage volumes recovered in tandem. These developments were driven in large part by the greater use of FX swaps for managing funding and greater electronification of customer trading. They led to further concentration of trading in a few financial hubs. JEL classification: C42, C82, F31, G12, G15. Turnover in global foreign exchange (FX) markets reached $6.6 trillion per day in April 2019. This is up from $5.1 trillion per day in April 2016 and marked a return to the long-term upward trend in turnover recorded in each BIS Triennial Central Bank Survey since 2001. In this article, we explore the recent evolution in the size and structure of global FX markets by drawing on the latest survey. The global FX market is more opaque than many other financial markets because it is organised as an over-the-counter (OTC) market built upon credit relationships. In recent years, changes in market structure, such as the internalisation of trades in dealers’ proprietary liquidity pools, further reduced the share of trading activity that is “visible” to other market participants (Schrimpf and Sushko (2019) in this issue). The Triennial Survey provides a comprehensive, albeit infrequent, snapshot of activity in this highly fragmented market.2 1 We thank Sirio Aramonte, Claudio Borio, Alain Chaboud, Ying-Wong Cheung, Stijn Claessens, Torsten Ehlers, Ingo Fender, Brian Hardy, Wenqian Huang, Robert McCauley, Dagfinn Rime, Maik Schmeling, Olav Syrstad and Philip Wooldridge for helpful comments and suggestions.
