The US is scooping up treasury bonds in an effort to raise their price and push yields down – but it’s not working

The bond market is driving the Trump administration crazy. Last week, the treasury secretary, Scott Bessent, announced that the government would sharply ramp up its purchase of treasury bonds, in an effort to raise their price and thus push down their yield, which amounts to the interest rate the government pays on its debt.

It didn’t quite work as planned. Yields on treasurys fell after Bessent’s bond market intervention but soon bounced back. By Friday afternoon, the yield on the 10-year treasury was back near where it was before the secretary’s announcement. The yield on the 30-year bond was again trading around its highest level in 20 years or more.

The enormous US debt under Trump will hobble the next Democratic administration – just as the GOP planned

• Why is the Trump administration causing turmoil in the bond markets?

You could pin the US’s staggering $40tn in government debt to Donald Trump’s Keystone Cops-style governance. Tariffs he sold as a new source of revenue were struck down by the supreme court, forcing the government to return tens of billions of dollars to importers. Elon Musk’s “department of government efficiency” (Doge), ostensibly created to stop wasteful government spending, decimated federal programs and probably killed millions of children, but did nothing to close the budget deficit. The burst of inflation following Trump’s misguided adventure in Iran sharply raised the cost of serving the government’s obligations.

Yet as the federal debt hits an all-time high, up from about $35tn when Trump took office less than two years ago, it is worth noting that the US’s gargantuan indebtedness is in fact the product of a longstanding Republican strategy that took shape well before Trump could even dream about gold-plating the White House. It was called “starve the beast”.
