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. Finally, no other currency is threatening the dominance of the U.S. dollar—at least, not yet….

China's Awkward Exchange Rate Regime: an Update

As 2016 draws to a close, it’s natural to look back over the year’s posts. With all the swirling concerns about China-U.S. relations—including the selection of the protectionist co-author of Death by China to head a new White House National Trade Council—we wondered whether our February doubts about China’s exchange rate regime remain intact.

The answer is yes, but for reasons radically inconsistent with President-elect Trump’s promise to declare China a currency manipulator on his first day in office. Like any country with a fixed exchange rate, China’s central bank intervenes actively to maintain its (evolving) currency target. But, for the past two years, the People’s Bank has been intervening to prevent (or at least to slow), rather than promote, the depreciation of its currency versus the dollar. That is, the RMB remains overvalued compared to what it would be in the absence of official intervention.

And, despite secretive instincts of China's authorities, the evidence is there for all to see....

China's Awkward Exchange Rate Regime

A recent op-ed in a major Chinese English-language newspaper, The People’s Daily, asserts that George Soros “has declared ‘war’ on China, claiming he had sold short Asian currencies.” For those who observed firms like those of Mr. Soros profiting from the collapse of the British pound in 1992, a speculative attack on China’s currency, the RMB, merits close attention.

There are surely parallels to that earlier episode where Soros' firm is reputed to have made $1 billion in a couple of days. Yet, it would be difficult to overlook the enormous differences. Perhaps most important, the United Kingdom was committed to maintaining the free flow of capital across its borders. This is in stark contrast to China, where policymakers have been tightening capital controls in recent months....

Is China's devaluation a game changer?

Since 1978, China has engaged in an unprecedented and wildly successful experiment, moving gradually from a command economy to one based on markets; in small steps transforming a system where administrators controlled the goods that were produced to one where prices allocate resources. There were surely miscalculations along the way. But, even big blunders could largely be concealed. Until now!

What has changed in recent months? The day has come for China to become more closely integrated into the global financial system, and this has a number of implications. 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....

China's Capital Controls and the Exchange Rate Regime

When the Chinese government wanted to damn the great Yangtze River, it moved more than a million people. When it wanted ring roads running through the 20 million people of Beijing, China built 270 miles in less than 30 years. So, when Chinese leaders say that they want Shanghai to be a global financial center and their currency the renminbi (RMB) to be an international leader, it’s natural to ask how, when, and at what cost...
