Apologies in advance for this very long thread, but as regular readers know, I worry greatly about common misunderstandings of the role of reserve currencies. The author seems to assume that what makes a currency a dominant reserve currency is...

But while a low frictional trading cost is a necessary condition, it is not nearly sufficient. A quick glance at the role of the...

In the next five decades, however, when the global economy was substantially rebuilt and needed to export excess savings, the US automatically became a permanent net...

This was no mere coincidence. To me it suggests three things. First, that reserve currency status is a function of a lot more than low-cost trading. In fact given that the cost is already so low, and seems to be in permanent decline...

What seems to matter a lot more is the willingness of the reserve-currency country to run large imbalances in response not to its own needs but rather to the needs of the rest of the world. As an excellent...

CFR resource shows, the US typically absorbs 40-50% of global imbalances, and the Anglophone economies — with similar financial markets all of whom, like the US, punch way above their weights as international reserve currencies — collectively...
Given that China's currency (and that of other surplus countries, like Japan) punches so far below it's weight, it is surprising that anyone would argue that there is no relationship between the international status of a currency...

and its willingness and ability to absorb global imbalances.
Second, the reason these countries are "willing" to accept major reserve-currency status has more to do with ideology than with economic rationality, driven by, and reinforcing, the disproportionate power of...

show in our book, is that these reserve-currency countries have constantly to choose between allowing unemployment to rise or allowing debt to rise. They have mostly chosen the latter.
And third, while China has been promising for nearly two decades that its currency will achieve dominant reserve status within five years or so, in fact the RMB is probably the least important of the top ten currencies given China's status as the second largest economy...

NZD 9.4
HKD 8.9

GPB 4.2

USD 3.6
Yen 2.9
Can. dollar 2.7
Euro 2.2

There are a lot of problems with this table, not least because it reflects a single point in time, and obviously the smaller the economy, the more likely it is to be an outlier, but it is still interesting.

This talk about Europe's ability to wield its holdings of US Treasuries as a political tool is as divorced from reality as the talk about China's ability to wield its holdings of US Treasuries as a political tool.

For all the huffing and puffing, Chinese holdings of US assets actually increased. This shouldn't have been a surprise. If you run massive trade surpluses, you have no choice but to acquire foreign assets, and if you won't acquire the alternatives, you must buy US assets.

These analysts seem to forget that you cannot change your capital account without also changing your trade account, and that you cannot change your external imbalances without also changing your internal imbalances.
1/7 EU commissioner for trade Maroš Šefčovič is absolutely right to question the usefulness of the WTO: "If the WTO is to meet today’s challenges, its rules must be fair and deliver balanced, legitimate outcomes. Currently, they do neither." ft.com/content/2ff1d4…
2/7 The fact that decades of the largest, persistent trade imbalances in history have largely been WTO compliant suggests strongly that the WTO is more about maintaining legal fictions than it is about discouraging the adverse impact of trade intervention on the global economy.
3/7 As Keynes (and many others) pointed out nearly a century ago, evidence that a country is intervening in trade shows up very clearly in the form of persistent, beggar-thy-neighbor trade surpluses. If the latter exists, then the former exists.
1/6 Reuters: "Chinese leaders have pledged to "significantly" lift household consumption’s share of the economy over the next five years, but have not given a specific target." reuters.com/world/asia-pac…
2/6 If we assume that Beijing hopes to raise the consumption share of GDP by 3-5 percentage points (roughly a third of what it would need to be a more "normal" low-consuming economy), consumption would have to grow by 1-2 percentage points faster than GDP over the period.
3/6 That's a pretty big gap, and one we have never yet seen in the past 3-4 decades of Chinese growth. The good way to manage this, of course, would be for consumption growth to accelerate, although it is not at all clear what would cause that acceleration.

2/7 open external accounts began to implement trade restrictions and otherwise control their external accounts. It started earlier, when economies that controlled their external accounts implemented trade and industrial policies that led to beggar-thy-neighbor trade surpluses.

1/6 Wall Street bankers and owners of movable capital would hate it, but if the rest of the world were to reduce its dependence on the US dollar, this would be good for the US economy, good for US manufacturing, and good for US farmers and workers. wsj.com/finance/curren…
2/6 The claim that the US benefits from the global use of the dollar is one of those things that people believe even though they can't explain why – except perhaps in terms of sanctions. None of the world's fastest-growing economies (including... foreignaffairs.com/united-states/…
3/6 advanced economies like the US in the 100 years before the 1970s, Germany in the same time period, or post-war Japan, Taiwan and South Korea) had major reserve currency status, and yet they all had rapidly growing economies driven by even more rapid growth in manufacturing.
1/4 Bloomberg: "“Even with strong determination and sufficient resources, transforming China’s economy into one driven by consumption and services will take years,” Goldman said. “With a more reluctant, measured approach, it could take decades.”" bloomberg.com/news/articles/…
2/4 Goldman is right, of course, unless a debt crisis, or a serious acceleration of trade war, forces a much faster, disruptive adjustment. While the latter might happen, the former is, for now at least, pretty unlikely.
3/4 A long adjustment, however, means a Japanese-style adjustment over two or three decades, in which consumption growth continues at more or less the same pace it had in the past while GDP growth drops sharply, and investment growth goes negative.
