Takeaways by Dark Side of the Boom™

• Wednesday’s quarterly refunding could mark the biggest change in Treasury issuance guidance since early 2024, with Wall Street increasingly expecting Washington to give itself more freedom to reduce long-duration supply.

• The temptation is obvious. Thirty-year yields remain above 5%, and shifting issuance toward bills and shorter notes could take some immediate pressure off the long end. But it does not make the borrowing requirement disappear.

• Bills already represent roughly 22% of Treasury debt outstanding, above the 20% level previously suggested by Treasury’s advisory committee as an average over time. America is increasingly financing a structural deficit with increasingly short-duration paper.

• The real question is not whether Bessent can temporarily lean against long yields. It is whether investors eventually demand a higher price for a debt-management strategy that exchanges duration risk today for refinancing risk tomorrow.

Bessent’s Next Treasury Experiment

There are moments in the Treasury market when the auction calendar is just plumbing, and then there are moments when the plumbing tells you something considerably bigger about how Washington intends to finance itself.

Wednesday could be one of those moments.

After Treasury Secretary Scott Bessent surprised dealers with his willingness to intervene in the bond market to drive down yields in recent months, Wall Street is now girding for the biggest revamp in guidance for US Treasuries issuance since early 2024.

Many dealers expect the Treasury to alter the guidance in its quarterly policy statement, which for more than two years has laid out steady plans for note and bond issuance. A shift in Wednesday’s announcement could pave the way for potential cuts in 2027 to sales of the longest-dated debt, balanced by bigger auctions of bills and shorter-term notes.

Some are prepping for more drastic action. Citigroup Inc. predicts the Treasury will announce cuts to sales of 20- and 30-year bonds starting this month — effectively violating the guidance issued in the last so-called quarterly refunding statement. Just one week after that last plan, Bessent unexpectedly ramped up buybacks of outstanding securities, in a move seen as a reaction to a surge in yields.

“Buybacks are too small to really move the needle,” April LaRusse, head of investment specialists at Insight Investment, said in an interview. She put it simply: “if you’re running the Treasury and your main power is issuance, if you don’t like where the yields are, you adjust your issuance.”

The proviso for any major shakeup this week is that yields have retreated since longer-dated rates hit their highest in more than two decades in early October. Still, 30-year bonds on Friday were trading with yields above 5.30%, around levels seen in mid-August when Bessent intervened with his expanded buyback program.

Another consideration: relying even more heavily on bills, which mature in up to a year, to meet expanding funding needs at some point is bound at some point to test the appetite of investors. With rapidly maturing bills having to be refunded constantly, the US now auctions in excess of half a trillion dollars in any given week, leaving the Treasury exposed to sudden swings. Last week, officials sold a record $839 billion.

“Guidance is more likely than immediate action” to alter issuance strategy, said Phoebe White, head of US rates strategy at UBS Group AG. Still, the Treasury’s recent “unconventional” behavior does “increase the odds that Treasury actions continue to deviate from historical precedent,” she said.

UBS is among those seeing no change in actual issuance until May. The Treasury already opened the door to a shift in August, when officials made a subtle tweak to their guidance, saying they were evaluating potential future “changes” in coupon and floating-rate note sales instead of the previous reference to potential “increases.”

As for next week’s quarterly refunding auctions, unchanged issuance sizes would mean they will total $125 billion, and consist of:

Ever since Bessent’s predecessor, Janet Yellen, established the current guidance about expecting to hold note and bond sales steady for quarters to come, dealers have expected increases to resume in time. That’s due to the ever-increasing amount of public debt, with the government running annual deficits of around $2 trillion. On Monday, the Treasury will offer an update of its latest estimate of quarterly borrowing needs.

In preparing for Wednesday’s statement, the Treasury used its regular pre-refunding questionnaire of primary dealers to ask about “structural changes in investor demand” for Treasuries, and “what futures changes to auction sizes should Treasury consider.”

At the heart of what the Treasury’s been engaged in is its “discomfort with the level of yields,” JPMorgan Chase and Co. strategists led by Jay Barry wrote in their refunding preview. Even so, the team expects the Treasury to maintain the “next several quarters” language into 2027, and to keep auction sizes unchanged through next August, before embarking on a series of increases focused on 2- to 10-year securities.

JPMorgan’s view contrasts with the many dealers anticipating a change. The Barclays Plc team led by Anshul Pradhan suggested officials replace the “at least the next several quarters” language with “the coming quarters” — a move they say would provide the Treasury with “flexibility over both the timing and composition of issuance.”

Some version of the current language has been in place since January 2024, despite intermittent investor calls to get rid of it. Bank of America Corp., Goldman Sachs Group Inc. and UBS are among other banks on the lookout for a change.

Observers will also on Wednesday be on watch for discussion points from the Treasury Borrowing Advisory Committee, a panel of investors, dealers and other market participants that meets with top officials. Any TBAC feedback on the market’s ability to keep absorbing bigger bill sales could be particularly meaningful.

Treasury has effectively been leaning on the short end because coupon issuance has not risen sufficiently to absorb the government’s expanding financing requirement. If Washington decides that the solution to uncomfortable long yields is even more bill issuance, that 22% share becomes less of a temporary feature and more of a financing strategy.

There are perfectly reasonable arguments for doing it.

Money-market funds remain enormous. Regulatory liquidity demand remains substantial. Stablecoins have been touted as another potential structural source of T-bill demand. And if investors are willing to absorb the paper cheaply, there is no law saying Treasury must issue more 30-year bonds simply because that is how previous cycles were financed.

Stablecoin demand has yet to arrive at anything like the scale sometimes advertised, while there are early signs that appetite for continually larger bill issuance may be becoming less elastic. Nobody knows where the market’s saturation point sits because the US has never tried to finance deficits of this size with this particular investor base and this particular maturity mix.

That is why the Treasury’s pre-refunding questions were unusually revealing.

Officials specifically asked primary dealers about structural changes in investor demand and what future changes to auction sizes Treasury should consider.

You do not ask that question because you are perfectly satisfied with the status quo.

Treasury has already tripled buybacks in the 10- to 30-year sector to $6 billion per operation, and most dealers expect that amount to remain in place. Buybacks are still too small relative to the size of the market to mechanically dictate yields, but their importance may be more about signalling than firepower.

If Treasury explicitly describes buybacks as part of the permanent toolkit for managing the maturity composition of outstanding debt, the market will naturally assume the programme can become larger or more flexible when liquidity deteriorates or yields become uncomfortable.

That creates an interesting policy loop.

Treasury sells more at the front end because long yields are expensive, buys back some older long-duration securities to improve market functioning, and leaves itself the option of changing coupon issuance if the curve does something Washington dislikes.

None of this is quantitative easing, and it would be wrong to pretend otherwise. Treasury cannot manufacture reserves and set the overnight policy rate. But debt management absolutely affects the amount of duration private investors must absorb, and at these deficit levels that distinction increasingly matters.

The immediate market reaction on Wednesday could therefore be straightforward.

Any credible hint of reduced 20- and 30-year supply would probably be welcomed by the long end. A change from “at least the next several quarters” to something softer such as “the coming quarters” would also matter because it would effectively give Bessent permission to alter issuance without appearing to reverse an explicit commitment.

But I would be careful about confusing a tactical rally in bonds with a solution to the underlying problem.

If anything, the numbers are moving in the opposite direction.

The government’s financing requirement is simply becoming large enough that Treasury must increasingly decide where on the curve it wants the market to absorb the risk.

And that is the part I find most interesting.

Under Janet Yellen, the market debate was largely about when coupon auction sizes eventually had to rise to meet the deficit trajectory. Under Bessent, the question has become whether Treasury can actively manage the maturity mix to prevent that borrowing requirement from translating too quickly into higher long-term yields.

There is a logic to it. If investors are punishing you for duration, issue less duration.

But markets rarely give policymakers a free lunch.

Lean too heavily on bills and the government becomes more exposed to rollover conditions and short-term interest rates. Push more issuance into the 2- to 10-year sector and that part of the curve eventually has to clear at a price. Suppress long-duration supply for too long and you risk distorting the very term premium you are trying to manage.

That is why Wednesday’s refunding could matter far beyond the initial Treasury-market reaction. We may be watching the beginning of a more activist era of US debt management, one where Washington is no longer content merely to finance the deficit predictably but increasingly thinks about how the composition of issuance affects financial conditions.

Bessent may be able to take some duration out of the market.

He cannot take the deficit out of the market.

And over the long run, that distinction is likely to matter a great deal more than whether the next 30-year auction is $25 billion or a few billion dollars smaller.
