Foreign Exchange Trading: 2019 Edition

Every so often, new data provide us a glimpse of parts of the world that few people ever see. Last week, the BIS’s Triennial Central Bank Survey of Foreign Exchange and Over-the-counter (OTC) Derivatives Markets in 2019 provided just such a view. The headline is that average daily foreign exchange (FX) turnover, adjusted for double counting, is $6.6 trillion per day. That is, nearly 8% of global GDP changes hands in FX markets every day! (For a summary, you can listen here.)

Numbers of this magnitude raise a host of questions. In this post, we explore three: first, who is shifting such large volumes of currency around, and what motivates them? Second, history teaches us that disruptions in FX markets can destabilize the broader financial system: are there signs of emerging risks? Finally, what do we learn about the relative position of the U.S. dollar?

To anticipate our conclusions, the fraction of trading involving nonfinancial entities is relatively small, so the bulk of these transactions (like those in most financial markets) are between intermediaries. In addition, there are hints of growing systemic risk in the FX settlement system, so we need to remain attentive.

The most important is that as prices and quantities of financial assets (rather than goods) are determined in markets, bureaucrats lose a great deal of control. But, as recent events very clearly demonstrate, Chinese authorities are reluctant to let go....

To RMB or not to RMB? Lessons from Currency History

China is the world’s largest trader and (on a purchasing power parity basis) is about to surpass the United States as the world’s largest economy. China already accounts for about 10% of global trade in goods and services, and over 15% of global economic activity.

So, as China takes its place as the biggest economy on the globe, will its currency, the renminbi (RMB), become the most widely used international currency as well? Will the RMB supplant the U.S. dollar as the leading reserve currency held by central bankers and others, or as the safe-haven currency in financial crises?
