Summary

Justin Wolfers, professor of public policy and economics at the University of Michigan, explains the global bond sell-off as a rise in demand for loans driven by the AI buildout, large U.S. deficits, and geopolitical risk. He warns that fiscal repair is not on the political agenda and that a fiscal crisis could happen suddenly. The conversation also covers tariffs, inflation, the Fed, recession risks, gold, and the US-Canada trade conflict's impact on autos.

  • Global G7 bond yields have risen sharply over the past year, with Japan leading.
  • Wolfers attributes higher long-term rates to AI-related borrowing, U.S. deficits, and geopolitical risk.
  • He sees fiscal repair as absent from public policy and warns of a possible sudden fiscal crisis.
  • Tariffs are discussed as a tax that raises revenue but also consumer prices, with limited fiscal capacity.
  • The Fed is expected by markets to hike before the election, though Wolfers downplays the exact timing.
  • He dismisses gold as an investment and the gold-to-oil ratio as a macro signal.
  • The US-Canada trade conflict is framed as damaging the integrated North American auto supply chain.
  • Recalibrated geopolitical risk may lead to higher military spending.

Long-term government bonds look unattractive.
The global bond sell-off is driven by a surge in demand for loans: the AI buildout is causing companies to borrow heavily, the U.S. government is running a historically large non-recession deficit with no political appetite for fiscal repair, and elevated geopolitical risk is likely to force more military spending. Those forces should keep long-term borrowing costs biased higher and create risk of a sudden fiscal crisis, making long-duration government bonds unattractive.

Geopolitical risk supports defense spending.
Geopolitical risk is elevated and the post-war U.S. security umbrella is less certain. If Europe no longer feels secure, it will invest more in its military; the U.S. may spend more to sustain global military dominance; and Middle Eastern countries worried about the state of the world may also spend more. That points to a multi-year tailwind for defense spending.

Tariffs threaten North American auto manufacturing.
The U.S.-Canada tariff conflict threatens the integrated North American auto supply chain built under NAFTA and USMCA. A tariff wall would leave American automakers unable to get Canadian parts at competitive prices and Canadian manufacturers without nearby customers, making North American auto manufacturing smaller, less dynamic, and less competitive.

Gold is not worth holding.
Gold is just a yellow metal that does not do anything helpful, most serious economists do not look at gold prices, and the gold-to-oil ratio is not a reliable macro or recession signal. Wolfers explicitly does not hold gold.
