I initially shelved this to read on the hoped-for assumption that it was a more ambitious book than it is. Fortuitously, I ended up actually reading it because the narrow subject matter it does tackle is something I needed to learn about for another project. So this is a narrative history walking through the steps and crises not of the international finance system in general, but of the gold standard or lack thereof. It begins in the early 1800s in Europe, and remains focused there and on the United States until more or less the 1980s, at which point it finally expands to discuss Asia and the largest South American economies.
I'm always wishing books like this were more mechanistic than narrative. Usually, the problem is that I want mechanistic hypotheses that the available data can't evaluate. This time, I think a big part of it was just that the subject matter is relatively narrow, and much of the mechanistic content is implicit in related issues that Eichengreen doesn't see fit to explain. I'll certainly admit that if I had taken the time to review the macroeconomic concepts involved here, which I have learned at least twice before, I probably would've gotten more out of the book. Still, it seems a bit odd to me that the preface frames the ups and downs the narrative describes as more or less the outcome of a single class struggle.
One side of this more or less make sense to me. The gold standard limited the growth of the money supply and thus prevented both some amount of secular growth in the economy and monetary policy to address recessions. The story of the book is one of governments constantly feeling pressure to devalue their currency, thus increasing export competitiveness and potentially wage growth. The confusing part is that this pressure is only obliged when voting rights are expanded and trade unions become politically influential (though even this change is one that is essentially asserted in the preface and whose influence is largely inferred throughout the narrative). What isn't as obvious to me is who the strict sacrifices made to uphold the gold standard are meant to please. Investors who own debt sufficient to see the value of that debt diminished by inflation and augmented by deflation. Is that all there is to it? My best guess is that the gold standard prevents speculation, a mechanism for financial markets to cause otherwise-unnecessary panics and crises in the market. However, the book suggests that this was a mistake; speculation is more limited by fundamental shifts than imagined and when those fundamentals are bad, the crises will occur regardless of the standard. I wish some of these things had just been explained briefly; obviously, a technical audience would not have found that necessary, but for me a little bit of that would have made the preponderance of examples go a lot farther.
That said, I definitely got what I wanted in terms of background and examples on the gold standard for my current project. The main take-home messages for me were these. First, that the gold standard was more of a winner/loser question than a "is this a good idea?" debate. I lean toward those explanations in general but had never heard one applied to this question. Second, I got a much clearer idea of what preceded the gold standard and how that transition occurred. Coins were made of metals at their exact values, and those values didn't change substantially as long as the value of the metals didn't change. Globalization glutted Europe with metals and increased the scale of international financial trading and investment along with the rest of trade.
Third, the main alternative to the gold standard is exchange rate pegging, which faces the same "trying to stop a river with a stick" issue that the gold standard does. In addition to the internal forces pushing for a consistent currency value, the big problem today is that extreme currency fluctuations are thought to create exchange rate wars, in which countries try to stay competitive by devaluing to counter devaluations of their trading partners. Overall, it seems like there is no ultimately effective way to avoid large fluctuations in currency value. The gold standard as an internal check doesn't work. The exchange rate reserve as an external check is equally ineffective. International cooperative organizations can be useful but only if they are backed by sufficient capital and have the major players on board. For instance, the IMF does not seem to have made a big difference in coordinating currency stability, but the US was able to achieve it in Europe through large and sustained loans.
One of the problems with the narrative rather than mechanistic approach is that it often isn't clear how much an event is due to fundamental economic circumstances and how much it can be attributed to human caprice. The fear that speculation could overwhelm real value in the economy seems to have been misguided. And on a few occasions, Eichengreen provides "rational" explanations for investor behavior that conventional wisdom suggests is something like a collective punishment for a lack of fiscal discipline. At times, political instability itself seems to be more influential than either competing policy might be. On the other hand, governments apparently valued their past reputation more than investors actually cared about. Then there are cases like Austria at the beginning of the Great Depression, a bank failure that might have been bailed out by other countries to protect the international gold standard if those other countries were not recent factors of a bitter war.
There is clearly a collective action problem at work in the system. Eichengreen makes frequent allusion to the fact that countries could easily devalue their currency without setting off the spiral of exchange rate drops if they just did it together, but apparently that has essentially never happened. It isn't entirely clear to me what the optimal cooperation scenario here with look like or how it would be superior to the absence of a consistent trend; devaluation seems to be a country specific strategy applied to deal with internal problems. Is it even possible for a coordinated strategy to provide those fixes? If not, what would be the broader goal of a coordinated strategy? Just to grow the money supply in general?
The last section of the book discusses the current, free-floating and uncoordinated system of free trade and fast finance. Here again I could have used some theoretical grounding. What are the pros and cons of a shared global currency analogous to the Euro? What sorts of perturbations could affect the present system and why are they likely/unlikely? Again, that grounding is something he warns up front I needed to bring to the table and I didn't, so I have no one to blame but myself.
