In Section 122, Congress endowed the president with narrow, temporary authority to impose tariffs “to deal with large and serious United States balance-of-payments deficits” (emphasis added). What Trump is complaining about — something he insists is a crisis but is not — is the balance of trade, not of payments. The United States does not have an overall balance of payments deficit, much less a large and serious one.

A trade deficit between the U.S. and a foreign nation occurs, mainly in connection with goods (which is just one aspect of international commerce), when imports are greater than exports. This is not really a problem for a variety of reasons — e.g., a trade deficit results in an investment surplus, the U.S. is a major services economy and often runs exported services surpluses that mitigate the imports deficit in goods, etc.

The balance of payments is a broader concept than the balance of trade. It accounts for all the economic transactions that take place between the United States and the rest of the world. Even without getting into every kind of transaction that entails, suffice it to say that foreign investment in the United States, coupled with the advantages our nation accrues because the dollar is the world’s reserve currency, more than make up for the longstanding trade deficit in goods.

Our overall payments are in balance. There is no crisis.

It’s vital to understand why Section 122 was enacted. There was a financial crisis in the late 60s and early 70s under the Bretton Woods system, when the dollar was tied to gold. Foreign countries that held dollar reserves could exchange them for gold at a fixed rate. Meanwhile, our government was spending at a high clip due to the Vietnam War and Great Society programs. This and the obligation to pay out gold put enormous pressure on the dollar. In response, in 1971, President Nixon severed the dollar’s tie to gold and — as several justices recounted in Friday’s Learning Resources opinions — imposed a temporary 10 percent import surcharge (a tariff) to stabilize the economy......

There is no rationale under Section 122 to impose tariffs. Because President Trump has no unilateral authority to order tariffs, he must meet the preconditions of Section 122 to justify levying them. He cannot. Not even close.
