I recently posted a piece on the trade deficit. I wrote in generalities there and broad estimates. I suppose I should have included a little more data.
I have a question about figure 2. The red line is the capital account, right? It is quite volatile. The black line is the trade deficit. Adding the net investment income to the trade deficit should give the current account. The net investment income is pretty stable. The current account and the capital account should be equal to each other (of opposite sign). So why is the capital account so volatile? Is it because of measurement error?
You said, "Foreigners would increasingly earn greater profits on their growing American investments. Over time, that would cause the dollar to depreciate. And, if that was happening, the trade deficit would naturally decline."
What do you make of Japan's growing current account surplus along with a trade deficit? It has been accompanied by a weakening yen and a growing trade deficit. Presumably the growing current account surplus is because Japan is earning greater investment income abroad than foreigners are earning in Japan. Shouldn't that increase the value of the yen? Instead the yen is decreasing in value and at the same time, the trade deficit is increasing.
Savers choose investments based on both risk and return. They willingly give up return because they are seeking more safety. One reason that capital flows to the US is because the US has a history of financial and public institutions that have demonstrated that they are capable of providing safety.
Why would the United States be better at investing in foreign countries than foreigners? Wouldn’t they understand their own investments better?
Why would foreigners be more risk averse than Americans?
What if risk were to reverse? Stocks in Japan underperformed for decades. Treasuries are backed by my tax dollars. These foreign assets are backed by?
Imagine that I maxed out my credit card and put it all it bitcoin. For a decade now I’m rich! What about tomorrow?
And do I own those assets? I certainly own the debt on the treasuries.
It seems that there are two narratives here:
1) foreigners are so stupid that we can get twice the returns investing in their own economy for them.
2) foreigners are so stupid that they give us free shit and we are totally going to default on them.
Now I’ve got a low opinion of foreigners, but neither if these two give me confidence in the situation. Especially since the best idea we could think of to do with the money is cheap plastic shit we throw out, paying people to be locked down in their home ordering uber eats, and wiping peoples butts in nursing homes.
3. Foreigners are older and poorer and more interested in liquid, low volatility assets compared to the younger, richer Americans (even within the US, it is well established that risk aversion is basically a function of wealth and age). Furthermore, America's comparative advantage in providing safe assets means that its main export product will be safe assets. This does not mean anyone is getting screwed, everything is priced in. Americans are just better at providing consistent returns, other countries are better at providing riskier and more profitable investments, so investors allocate money accordingly. Much like for trade of physical goods, specialization benefits both.
It is difficult for me to believe low yield America assets are the best investments that Chinese can come up with (being a society with tons of catch up growth and an average IQ of 105).
I might be able to believe that the Chinese communists are politically captured by exporters and force their citizens to save to much while restricting their investment options, but this would again be a kind of "foreigners are dumb and getting ripped off" circumstance.
As to Europe and Japan, I do have a low opinion of them, but again "foreigners are dumb". Best of the worst is still depressing.
As to old vs young, I think a better idea for the rest of the world would be to invest in making more babies rather then assuming that an also aging American demography is somehow going to turn around and send goods back to them when everyone is old just because they have slips of paper.
If they refuse, then I think we should again "tax" them in order to invest in us via tariffs and invest it in our own baby making.
"Furthermore, America's comparative advantage in providing safe assets means that its main export product will be safe assets."
Beyond being "hand wavy", if true we should charge people for the privilege. Which is what tariffs do!
If such a comparative advantage really exists, tariffs serve both to redistribute it and change its nature (say, from cheap imports to lower income taxes, as trump is doing).
I don't want to sound rude, but do you know *anything* about finance? So, you have a country with rule of law, constitutional protection against arbitrary seizure, and (more importantly), a long history of *actually* respecting property rights and honoring its debt. That alone is worth a significant premium over Chinese assets if you are care about risk. But let's say our Chinese investor abstracts all these considerations away. You know what is the best way to reduce your portfolio risl? To *diversity*. If you are a Chinese guy with a job and real property in China, then most of your income and wealth is already tied to China, and you really need to put your movable assets somewhere else to get an hedge. IQ does not change anything here. Again, you insist in seeing it as a zero-sum game when we *both* are better off for having the opportunity of investing in the other country.
"As to old vs young, I think a better idea for the rest of the world would be to invest in making more babies rather then assuming that an also aging American demography is somehow going to turn around and send goods back to them when everyone is old just because they have slips of paper"
They don't need Americans to produce goods, they just need Americans to return the amount promised on those pieces of papers and then *someone* to sell them goods in exchange of USD. You know which institution is really really good at evaluating how likely this is to happen? Yes, exactly, markets. No offense anonymous user with protonmail, I'll still take market prices as more informative than your opinion on whether this is a good idea or not.
"Beyond being "hand wavy", if true we should charge people for the privilege. Which is what tariffs do! "
No, the 19% foreigners *already* pay on all the income from their US investments is what they are charged for the privilege. And it's quite an heavy charge, given that unlike American taxpayers, they don't receive anything in return, but they're happy to pay it, so fine. Tariffs are a tax *on American consumers* which also lowers competition for American firms thus lowering *American* productivity. You want to squeeze foreigners more? Raise taxes on capital income. Tariffs only squeeze Americans, beyond having terrible second-order effects
I know that if the Chinese government artificially juices exports that capital has to go abroad by default. That isn't individual diversifying by choice so much as "this is my only option given the shitty options my government has given me."
Ditto for "let me stash capital abroad so I can flee if the government comes after me." These are less signs of American strength than foreign weakness.
I would note too that Europe and Japan have plenty of rule of law and they are running big trade surpluses with us too.
"They don't need Americans to produce goods, they just need Americans to return the amount promised on those pieces of papers and then *someone* to sell them goods in exchange of USD."
Who?
Real goods exist in the real world. Who's going to provide those goods for that paper if we won't? The Europeans? The Japanese? People also running huge trade surpluses with us and also with lower growth and aging populations?
China is running an ever escalating trade surplus with THE ENTIRE WORLD. *Someone* is going to have to turn around and start exporting back to them at some point for any of these pieces of paper to be worth something real one day.
"You want to squeeze foreigners more? Raise taxes on capital income."
I don't think it's particularly possible to raise huge taxes on capital income for only foreigners. Unless you're looking to give guaranteed lifetime employment to an army of tax accountants and lawyers.
Germans want to buy Word and Excel. Microsoft opens up an office in Berlin and sells it to them. Microsoft now has profits in Euros. Americans buy things from Europe with those Euros. Who do you think is better suited to manage that office than Microsoft?
You're sort of begging the question in your reasoning here. I'm not saying anyone is stupid. You're bringing that to the conversation and then you're trying to make sense of what I wrote. It's not going to make sense to you if your conclusion requires foreigners being stupid.
Why don't they make their own Microsoft and Excel? It's not exactly advanced software.
Why don't the Chinese just violate the copyright? I hear they are good at that. They are the real drivers of this trade deficit stuff.
The fundamental question you're posing is why do foreigners lend to us at X% so we can lend back to them at 2X% in assets in their own country.
That seems stupid.
I kind of buy that the Europeans and Japanese are inferior to us and that we are the best game in town (best via least worst option). That's still a sad story that I don't think ends well.
China is harder because it's a country of 1.5B people with 105 IQ that should still be in a massive catch up growth phase.
The only explanation I've ever gotten is the ChiComs are communists and East Asians are uncreative ant people and therefore through a mixture of their creative inferiority and the communists authoritarian political capture by exporters they are forcing poor Chinese workers to save too much and invest in US treasures which doesn't seem like a great idea for anyone. Kind of seems like the kind of thing that will blow up one day.
Personally, I think they should invest more in their domestic economy and especially making more babies, but maybe communists and/or asians just can't manage it.
I hate being the best of a bad lot. "Stupid" seems like a good word for it.
Trump recently said something to the effect that if the tariffs eliminated several hundred billion dollars in trade then that meant the U.S. had saved that money. Similar to if I cut off my leg just below the knee I would save blood and other resources for the rest of my body.
There's a scene in Jabberwocky where a beggar has cut off his foot to encourage donations. He appears in a later scene with both feet cut off. There seem to be limits to this type of economic policy.
Coincidentally, I’m pretty sure today’s post from Noah Smith is making much of the same point as you are. Great minds think alike!

Adding the net investment income to the trade deficit should give the current account. The net investment income is pretty stable.

Perhaps its the capital flows that drive the deficit and not the reverse...
Why do foreigners give us money at X% when there are investment opportunities in their own country at 2X%?
