On Some Misunderstandings of the ‘Balance of Trade’

Responding to this Cafe Hayek post, a regular reader e-mails the following to me:

1 – I have never heard of Trump or anyone being against a Chinese or Japanese investing their money IN the US – he complains about a Chinese glass factory IN China exporting to the US especially if the exchange is subsidized. – I am not in favor of his position but do not think it is quite what you write.

2 – the two situations are not comparable either – the US fellow is investing US dollars in the US – The Chinese fellow has to convert yuan into dollars before investing in the US – a big positive for us. He not only soaks up some of the trade balance to get the dollars but then uses them to increase American employment rather than Chinese employment at home.

This reader is mistaken, but his error is forgivable given the swirl of confusions that engulf discussions of trade and so-called ‘trade balances.’  Here’s is my (edited, expanded, and grammatically corrected) reply to him:

Whenever Trump and others complain about the U.S. trade deficit they are necessarily complaining about foreigners investing in the U.S. or in dollar-denominated assets.  The fact that Trump and other such complainers do not understand that they are complaining about foreigners investing in the U.S. or in dollar-denominated assets does not change the economic reality.  Every cent of the U.S. trade deficit – or, more accurately, every cent of the U.S. current-account deficit – is offset by a cent in the U.S. capital-account surplus.

If a Chinese exporter uses dollars to build a plant in China, he must first convert those dollars to yuan.  And then we must ask what the new holders of the dollars do with them.  Do they spend them on U.S. exports?  If so, the U.S. trade deficit doesn’t rise.  If they invest them in the U.S., then the U.S. trade deficit rises for the reasons explained in my post (and detailed further in the following paragraphs).

As for your second point, in both examples in my original post it is U.S. dollars that are invested in the U.S. (that is, in the Ohio glass-making factory).  The details of how the Chinese entrepreneur who actually carries out this investment got those dollars are immaterial (assuming, of course, that it was through peaceful commerce).  The Chinese entrepreneur might well have gotten most, or even all, of those dollars in exactly the same way that the American is assumed to have gotten those dollars: by selling outputs to Americans who paid for those outputs using U.S. dollars.

But even if Mr. Cho, the Chinese entrepreneur, got all of his dollars by converting yuan into them, then the person who sold to him the dollars had to get those dollars from somewhere – and they were, at some point, gotten by the sale of Chinese exports to Americans or by Chinese earnings on investments in dollar-denominated assets (which assets were bought with U.S. dollars gotten originally from the sale of exports to Americans).  The fact that the specific dollars in question might perhaps have been initially earned by some other Chinese individuals and then sold (for yuan) to Mr. Cho does nothing whatsoever to alter the economics of the situation: in both cases – the American building the glass-producing factory in Ohio, or the Chinese person building that factory – the economic consequences for Americans are identical.

By the way, it’s incorrect to say that the Chinese entrepreneur who, in order to get dollars to invest in America converts yuan to dollars, “soaks up some of the trade balance.”  In fact he does no such thing if he invests all of those dollars in the Ohio factory.  Because foreign direct investments, just like foreign holdings of U.S. dollars, are not recorded on the U.S. current account, the trade balance is unchanged if this investment occurs compared to if the previous Chinese owner of those dollars simply stuffed them into his mattress in Shanghai.

Yet your belief that Mr. Cho’s purchase of dollars with yuan “soaks up” of some of the U.S. trade deficit reveals an understandable misconception, but a misconception nevertheless – namely, that the U.S. trade deficit consists only of funds withdrawn from the U.S. economy and not returned to it either as demand for U.S. exports or as investments in the U.S.  In fact, and as alluded to earlier, the U.S. trade (current-account) deficit rises whenever foreigners ‘return’ dollars to the U.S. on the U.S. capital account – which include foreigners’ investing, in whatever ways (passively or actively) in U.S.-based equity (such as the factory in Ohio, or buying a single share of Apple stock from an American), foreigners lending funds to Americans (including to the U.S. government), foreigners purchasing real estate in America, and foreigners simply holding Federal Reserve Notes.

Some of the complaint about the U.S. trade deficit is that much of it is converted into debt owed to the U.S. Treasury.  While I share concerns about Uncle Sam’s profligate borrowing, (1) I do not care what are the nationalities of the creditors, for that is irrelevant, and (2) the problem is Uncle Sam’s fiscal profligacy and not trade policy or American-consumers’ profligacy.  Another source of misguided worry about the U.S. trade deficit is that foreigners simply hoard large piles of Federal Reserve Notes.  If and to the extent such hoarding occurs, that is the best of all possible outcomes for us Americans, for it means that we get valuable goods and services from foreigners in exchange for mere pieces of paper smeared with green and black ink and featuring nothing but corny drawings, the signatures of some American mandarins, and monochrome portraits of dead American statesmen.

Adam Smith’s wisdom warrants repetition here: “Nothing, however, can be more absurd than this whole doctrine of the balance of trade.”
