TARRIF WARSThe Trade Deficit Isn’t an Emergency – It’s a Sign of America’s Strength
A trade deficit is often viewed as a problem. And yes, the U.S. trade deficit is both large and persistent. But far from a national emergency, this persistent deficit is actually a sign of America’s financial and technological dominance. Trump’s extreme tariffs, rather than reviving U.S. manufacturing, will erode the very pillars of the country’s economic dominance, at a steep cost to American firms and families.
When U.S. President Donald Trump imposed sweeping new tariffs on imported goods on April 2, 2025 – upending global trade and sending markets into a tailspin – he presented the move as a response to a crisis. In an executive order released the same day, the White House said the move was necessary to address “the national emergency posed by the large and persistent trade deficit.”
A trade deficit – when a country imports more than it exports – is often viewed as a problem. And yes, the U.S. trade deficit is both large and persistent. Yet, as an economist who has taught international finance at Boston University, the University of Chicago and Harvard, I maintain that far from a national emergency, this persistent deficit is actually a sign of America’s financial and technological dominance.
The Trade Deficit Is the Flip Side of an Investment Magnet
A trade deficit sounds bad, but it is neither good nor bad.
It doesn’t mean the U.S. is losing money. It simply means foreigners are sending the U.S. more goods than the U.S. is sending them. America is getting more cheap goods, and in return it is giving foreigners financial assets: dollars issued by the Federal Reserve, bonds from the U.S. government and American corporations, and stocks in newly created firms.
That is, a trade deficit can only arise if foreigners invest more in the U.S. than Americans invest abroad. In other words, a country can only have a trade deficit if it also has an equally sized investment surplus. The U.S. is able to sustain a large trade deficit because so many foreigners are eager to invest here.
Why? One major reason is the safety of the U.S. dollar. Around the world, from large corporations to ordinary households, the dollar is used for saving, trading and settling debts. As the world economy grows, so does foreigners’ demand for dollars and dollar-denominated assets, from cash to Treasury bills and corporate bonds.
Because the dollar is so attractive, the Federal Reserve gets to mint extra cash for use abroad, and the U.S. government and American employers and families can borrow money at lower interest rates. Foreigners eagerly buy these U.S. financial assets, which enables Americans to consume and invest more than they ordinarily could. In return for our financial assets, we buy more German machines, Scotch whiskey, Chinese smartphones, Mexican steel and so on.
