How to Win a Trade War: Soumaya Keynes on Trump, China, and Her Great-Great-Uncle Maynard

“The rules-based system just hasn’t worked. China’s system is so opaque that you can’t see the subsidies. And when you’ve got China not interested in new rules and the US not interested in a referee, you’ve got two of the world’s biggest actors who aren’t on board.” — Soumaya Keynes

It would have been nice to get John Maynard Keynes on the show to get his critique of Trump’s trade war. But in the long run, we’re all dead — even old Maynard. So instead, we found his great-great-niece, Soumaya Keynes — Financial Times columnist and co-author of How to Win a Trade War: An Optimistic Guide to an Anxious Global Economy.

Having already appeared on Jon Stewart this week, Soumaya has a bit of Keynesian star quality about her. But she’s also a first-rate economist. Her thesis is that the old rules-based trading system that her great-great-uncle helped design after World War II is gone. And it ain’t coming back. China’s subsidies are so opaque that rules can’t be written to constrain them, let alone enforced. The US is no longer willing to submit to a referee. Without the two biggest players, no rules-based system is meaningful.

So — now what? Keynes says we must think like a trade warrior. Donald Trump should leverage the tools available — but use them strategically. Trump’s error in his second term was not being tough on China while being too tough on everyone else, especially allies like Canada and Mexico.

Soumaya Keynes’ most contemporary idea might be her most Keynesian one. John Maynard Keynes proposed penalties for countries running large trade surpluses as well as those running deficits — recognising that global imbalances are a two-sided problem. That idea didn’t make it into the 1944 Bretton Woods agreement. Eighty years later, in equally anxious economic times, his optimistic great-great-niece is reviving it.

Five Takeaways

•       Can Trade Wars Be Won? Yes, Sometimes: The conventional wisdom: no one wins a trade war. Keynes and Bown agree — in theory. In practice, countries in a weaker position cave. History has examples: France in the late nineteenth century told its trading partners they were renegotiating treaties, and the smaller partners complied. Trump’s tariffs in his first term produced concessions. The problem is not that trade wars can’t be won. It’s that the smaller power’s only defence — coordinating with other smaller powers — is extremely hard to sustain. There’s always an incentive to cut a deal first.

•       China Is the Doper on the Sports Field: Keynes’s sharpest analogy: the global trading system is like a sports game that needs rules to ensure a level playing field. China’s subsidies — cheap credit, corporate handouts, opaque support for state-linked companies — are the equivalent of performance-enhancing drugs. The problem is that unlike doping in sport, China’s subsidies are invisible. You can write a rule saying China won’t give these handouts. But you can’t verify compliance. And without enforcement, rules are meaningless. The WTO has not solved this. Nothing has solved this.

•       Trump Was Right About China, Wrong About Everything Else: Keynes is careful here. She credits Robert Lighthizer in Trump’s first term with identifying China as the real problem and building a focused strategy. In the second term, Trump put tariffs on everyone simultaneously — which dissipated leverage, alienated the coalition of allies needed to pressure Beijing, and mixed up the problem of China’s subsidies with grievances against Canada, Mexico, and the EU.
