Why The Protectionist Cure Could Be Worse Than The Globalization Disease

Dramatic promises to restrict international trade were a signature element of Donald Trump’s presidential campaign. So far, he seems to be following through, with an early reaffirmation of his intent to withdraw US participation in the Trans-Pacific Partnership (TPP).

An aggressive stance on trade played a key role in gaining the support of working class voters in Midwestern manufacturing states, where upset wins swept him into the White House. What is more, trade is one area in which Trump, as President, will have the power to act on his own without action by Congress. As Gary Clyde Hufbauer of the Peterson Institute has explained, both the US Constitution and past acts of Congress give the President ample authority to do things like withdraw from the TPP or NAFTA, label China a currency manipulator, or impose retaliatory tariffs on any country he sees as a threat to US economic security.

But how would American workers actually fare under a protectionist regime, especially older workers, and those with few skills and little education, who voted for Trump by wide margins? Not well. Here is why the protectionist cure could be worse than the globalization disease.

Calling out China as a currency manipulator won’t help

Trump has repeatedly blamed US trade deficits and job losses on currency manipulation, especially by China, which he charges with weakening the yuan to keep its exports artificially cheap. In fact, calling out China as a currency manipulator will not bring back jobs for the simple reason that the charge is obsolete. Far from holding down the value of its currency, China has, for more than two years now, been fighting to keep the yuan strong. Mexico, another of Trump’s favorite targets for retaliation, has been doing much the same, although the details of its policy differ.

When Chinese authorities want to weaken the yuan (or renminbi), they do so by asking the People’s Bank of China to buy dollars to add to foreign exchange reserves. The Chinese did that consistently until early 2014, but since then, as the following chart shows, China has been selling reserves at a frantic pace in an attempt to keep the yuan strong. Despite those efforts, fears of a trade war have pushed the yuan sharply lower since election day.
