Congratulations to Scott Bessent for hijacking the market narrative this week.

There wasn’t much on offer in terms of data or scheduled events, so the bar was low for stealing the show. Upsized Treasury buybacks — the latest manifestation of Bessent’s interventionist tendencies — easily fit the bill.

Bessent, who described himself last year as America’s “top bond salesman,” will be buying (back) more of his own wares from September. Not because he found his own pitch convincing, but because other people who aren’t compelled to buy or own US Treasurys as a matter of course or mandate didn’t. Didn’t find Bessent’s salesmanship convincing, I mean.

On Thursday, Bessent doubled down as yields retraced the prior day’s decline, telling CNBC that buybacks could be upsized further if necessary to — wink, wink — improve liquidity, which he called “very poor.”

“All we’re trying to do is get people to focus on the fundamentals,” he said, in the same interview. “Not trade the headlines during a quiet period in a thin market.”

The audacity on display in that chat was “impressive” — and befitting of an administration whose calling card is shamelessness. You gotta be pretty brazen to say something like that less than 24 hours after America’s national debt hit $40 trillion, up 33% in the short space of five years. The figures below, which I highlighted last week, are worth recycling.

At the current run rate, total outstanding public debt will be $50 trillion three summers from now. If rates don’t fall ~100bps or so, the cost to service that debt over a year will reach $1.7 trillion by the next election.

As debt servicing costs rise, comprising a higher and higher share of overall spending, investors demand even higher yields (more compensation for the inherent risk), pushing the interest bill higher still and so on.

Bessent was (obviously) right to tell CNBC “there’s nothing magic about the $40 trillion number,” but the point isn’t about any threshold, it’s about optics. As I put it Monday, in an article that looked prescient just 36 hours later, the Treasury has a PR problem. If you’re the nation’s “top bond salesman,” you don’t make things any better by showing up on business television to talk up the “fundamentals” while the chyron sitting just below the tip of your tie testifies to the parlous state of America’s finances.

A more prudent Treasury secretary would’ve either i) tipped the upsized buybacks earlier this month, in the QRA, and made it clearer than Bessent did that Treasury’s considering cutting coupon auction sizes sooner rather than later or ii) stayed out of this until the next QRA in November. Those are regularly scheduled Treasury communications events, and as such they’re the natural place for telegraphing shifts. By announcing the upsized buybacks between QRAs — and just two weeks after the last QRA — Bessent conveyed a sense of panic.

One common refrain says markets stop panicking when policymakers start, but as we’ve seen time and again with — ironically in the context of Bessent the interventionist Treasury chief — the Japanese yen, markets have a nose for fear. Like sharks smelling blood, they’ll push the envelope if they doubt the credibility and/or the commitment of this or that official backstop. Bessent should know: He made his fortune being just such a shark.

I worry Bessent’s opened a Pandora’s box. Unlike the Fed, he can’t conjure reserves to buy bonds. He has to sell Bills to fund the buybacks, and if this turns into a grudge match between Bessent and markets, one risk is a flood of short-term paper. Someone has to absorb that, and depending on the size, it could cause distortions in funding markets. Because that’s a non-starter, it’s pretty easy to see a path to stepped-up Fed RMPs in true “cleanup on aisle five!” fashion.

Again, Bessent should’ve let this play out on its own, which is to say he should’ve told Trump that the risks of intervening outweighed the rewards even if the bond market pushed yields even higher into the mid-terms. Ironically, that might happen anyway because, again, the vigilantes can sense the fear behind the castle walls.

“On the surface, the [buyback] operations are designed to increase liquidity at a point in the calendar when summer trading conditions and significant corporate issuance could strain the Treasury market [but] it is difficult for investors to fully embrace this rationale considering the outright level of 30-year yields and the recent spike in 30-year real rates,” BMO’s Ian Lyngen remarked, adding that it won’t be surprising “to see any initial drop in long bond yields largely eroded.”

“Bessent should clearly be aware that a nation’s fiscal fundamentals eclipse the stance Treasury is taking,” JonesTrading’s O’Rourke said. “The last thing anyone wants to do is be on the other side of a trade that requires fiscal discipline to emerge in Washington, DC,” he went on. “While the Treasury market has been soft since the election, we do not view it as dire [and Bessent] drawing attention to it may turn it into a problem.”
