The Shanghai Accord and other secret monetary agreements

In 1989, the Asia-Pacific Economic Cooperation forum was established in Shanghai, China. The founding of this organization is sometimes referred to as the Shanghai Accord; see below¹ for further details about APEC. More recently, in 2016, there was talk of another possible Shanghai Accord. 

First, let's go back in time a little while, to 1985.

Weakening the U.S. dollar then...

The Plaza Accord is a 1985 agreement signed by then-U.S. Treasury Secretary James Baker and the finance ministers of pre-unification West Germany, Japan, France, the UK and the other G8 countries. The intent was to guide the U.S. dollar lower versus the Japanese yen and German mark.

The Plaza Accord was motivated by the U.S. dollar's sharp appreciation with respect to other countries' currencies. It was put in place in order to jump-start growth while easing the U.S. current-account deficit. This would be accomplished by weakening the U.S. dollar and making U.S.-manufactured goods and services more globally price competitive.

...and now?

The Bank of China (China's central bank) has been under pressure to allow the Chinese yuan to transition to a floating currency. The yuan remains a pegged currency, which is not consistent with participating in a global economy. The International Monetary Fund included the yuan in its basket of global reserve currencies last year (2015 Special Drawing Rights), partly with the assumption that Chinese monetary policy would become more consistent with that of a free market, rather than a centrally-planned economy.

However, the yuan has been weakening against the US dollar.

The fear is that another sharp depreciation of the yuan would send the trade-weighted dollar sharply higher, perhaps even into hyperstrong terrain not seen since 1981 to 1984.

How to inspire household animal spirits

This article in the Wall Street Journal's MarketWatch publication, To stave off currency war, is it time for a coordinated response to the Chinese yuan? conjectured that another accord might secretly take place at the G-20 meeting of central bankers in February 2016, in Shanghai. Instead of paraphrasing, I'll include an excerpt.

Emphasis mine:

Analysts at Bank of America Merrill Lynch drew parallels between the mid-1980s and today. The Plaza Accord was spurred by weak growth, macro divergence, and interestingly in light of the current political trends, rising protectionism in the U.S... Leading up to the 1985 accord, interest rates and inflation were low, but macro-cycles were out of sync and exchange rates were targeted to induce macro convergence. More important was that the global policy coordination inspired corporate and household animal spirits.

For conspiracy theorists?

The possibility of another monetary and global trade-influenced agreement having occurred was discussed in the financial press, shortly after the G20 meeting of 2016. Rumors of a secret deal in Shanghai, to weaken the U.S. dollar (greenback), in order to calm financial markets, have persisted.

Why focus on weakening the U.S. dollar again, rather than strengthening other currencies?  Because finance ministers recognized the following reality, some 35 years ago: It is far easier to weaken a strong currency than strengthen a currency with a weakening bias.

Market movements throughout the year have supported the rumors, as the effect of such an agreement, if successful, would have exactly this sort of effect:

The greenback has shaved off more than 3% since the gathering, sparking a rally in stocks, emerging markets assets, and commodities. To any conspiracy theorists, it’s all become quite clear...

Central banks are not supposed to take direct action to intervene in stock and commodity markets, thus a Shanghai Accord would need to be done in secret. That's why it has a conspiracy aura around it. It is not impossible that central banks would take action to weaken the dollar, in a concerted mutual effort, given the precedent of The Plaza Accord of 1985.

No evidence of a Shanghai Accord has ever emerged between then and now, in 2026.

¹APEC

As described by Stuart Baran in his Quora answer about APEC and reproduced here: 

The Asia-Pacific Economic Cooperation is a forum of 21 Pacific rim nations established in 1989. It was founded in response to the growing interdependence of Asia-Pacific economies as well as fears that highly industrialized countries would dominate economic activity in the Asia-Pacific region. Members are:

  • Australia
  • Brunei Darussalam
  • Canada
  • Indonesia
  • Japan
  • Republic of Korea
  • Malaysia
  • New Zealand
  • Philippines
  • Singapore
  • Thailand
  • United States
  • Chinese Taipei
  • Hong Kong
  • People's Republic of China
  • Mexico
  • Papua New Guinea
  • Chile
  • Peru
  • Russian Federation
  • Viet Nam
<end of Stuart's answer>

The composition of APEC leads me to question its ability to be effective as time passed; specifically, the inclusion of so many highly industrialized countries (U.S., PRC, Australia, Canada, Korea, Japan) that were the impetus for founding the group to begin with. 

Subsequent APEC concerns, e.g. slowing growth in Pacific Rim economies both large and small, are very real. The annual APEC Finance Meeting of 15 October 2016 (Lima, Peru) make this clear in that year's APEC Joint Finance Ministerial Statement, Part 3:

Our region [Pacific Rim countries] is facing several complex challenges that weaken growth and the recovery of our economies: low commodity prices, more volatile financial conditions, slowdown in trade accompanied by protectionist voices and the varying pace of growth...

In Part 6 of the same document, APEC commits to abstaining from the very acts of the 1985 Plaza Accord (competitive exchange rate revaluation) and the rumored act of a hypothetical 2016 Shanghai Accord:
We reaffirm our previous commitments on monetary and exchange rate policies. We will refrain from competitive devaluation, resist all forms of protectionism and not target our exchange rates for competitive purposes.

APEC's continued re-affirmation is clear from its 2025 Finance Ministerial meeting summary and even contains a caveat about the importance of floating currencies for regional trade:

We remain committed that our exchange rates reflect underlying economic fundamentals and note that exchange rate flexibility can facilitate the adjustment of our economies... We will refrain from competitive devaluations and will not target our exchange rates for competitive purposes.  
None of this makes much difference as long as China, who is a member of APEC, continues to maintain a fixed-rate currency that is pegged to the US dollar.
