The Treasury Department tripled the size of its next buyback of longer-dated government debt, to $6 billion, and Ira Jersey said the number still underwhelmed.
The buyback exists to bring long-term yields down. Jersey said $6 billion cannot do that, and that the program has to reach $10 billion or more before the size starts to matter — and even then he is not sure it works, because investors are pricing the deficit and 5% to 6% nominal growth, not the buyback.
"Ultimately, he's shooting BB guns instead of shooting a bigger round."
Jersey is Bloomberg Intelligence's Chief US Interest Rate Strategist, and his desk grades every Treasury auction. The 10-year sale that followed this announcement got an A+, the first the team has awarded since April 2025.

Key Takeaways
A $6 billion buyback is too small to move 30-year yields, and $10 billion is where Jersey thinks it starts to work
Even at that size he doubts it, because the deficit and nominal growth are what investors are pricing
A 5% 30-year bond is the rational price when nominal growth is running at 5% to 6%
The 10-year auction two hours after the disappointing buyback drew the first A+ grade Jersey's team has given since April 2025
Lower mortgage rates do not fix housing, because the constraint is supply and the size of the down payment
An extra 25 or 50 basis points on a 30-year mortgage is not what keeps buyers out
The yen intervention is a coordinated central-bank operation, not one official's bet
Japan holds a trillion dollars of Treasuries precisely so it can act in weeks like this one
1. A $6B Buyback Miss
Masser opened on the Treasury Department tripling the initial size of its next buyback of longer-dated government debt, an announcement investors met with some disappointment. Jersey's first response was a caution about the Treasury Secretary's public confidence in his own hand.
"Well, first we have to remember the House doesn't always win," Jersey said, and then gave the verdict: "today's buybacks announcement underwhelmed"
The market had been guided toward more than the $4 billion minimum previously discussed; the announcement came in at $6 billion, below what some had expected
The Treasury market fell on the news, and Jersey spelled out what that means for a general audience: "So the market sold off immediately on that information. When I say sold off, I mean the Treasury market. So price down, yield higher."
2. The A+ 10-Year Auction
The selloff did not hold, because a scheduled auction landed on top of it.
Less than two hours after the buyback announcement, the Treasury sold 10-year notes, and Jersey said the sale "went exceedingly well"
His team graded it A+, which he said was the first A+ it has given since April 2025: "So really strong demand at these higher yield levels here"
His conclusion is that the market absorbs a $6 billion-ish program without much drama
"And I think we found a range that we're going to continue to trade in here for at least a little while." — Ira Jersey
3. Why $10B Is the Number
Asked whether that meant the Treasury Secretary's plan is working, Jersey said the size is the problem.
"I think ultimately, he needs to do $10 billion or more in order to get yields lower," Jersey said, and put the current effort in the terms of the Charlton Heston gun metaphor the hosts had started: "Ultimately, he's shooting BB guns instead of shooting a bigger round."
Even at $10 billion he is unconvinced: "And even then, I'm not sure that it's going to work in a very significant way because people are still concerned about the deficit"
The deeper reason yields are where they are, in his account, is growth rather than supply. "Nominal growth rates are upwards of 5% and 6%, depending on how you measure growth in the U.S." — which is why he said "it's completely reasonable for you as a bond investor to price the 30-year bond at 5% or a little bit over 5% here"
4. Everything Is Not Awesome
Masser referred back to the show's earlier discussion of the K-shaped economy and passed on a viewer's question: are we wrong to think everything is awesome?
Jersey said "everything's not awesome," while holding that the economy is doing okay in aggregate
His framing was technological change producing winners and losers rather than a uniform slowdown
He cited "the 1990s, for example, manufacturing did really poorly, but technology did exceedingly well"
"So, you do have winners and losers as you have this creative destruction in the economy and move to new paradigms and new ways of doing business." — Ira Jersey
He flagged that the household side is not his own field, and said higher rates do reach the housing market and housing affordability
He also pushed back on the format of the question itself: "And we always try to, I think, narrow things down to lowest common denominator. What is the one thing that if we changed it, everything would change and be better?"
5. Housing Is a Supply Story
Jersey handed the housing argument to a colleague who does mortgage strategy at Bloomberg Intelligence, and the answer was not about the level of rates.
"It's really a supply problem, right? We don't have enough housing in the areas where that housing is demanded to be able to stabilize or bring prices down, regardless of the interest rate, right?" — Ira Jersey
The rate move that dominates commentary is not the binding constraint on a buyer
"An extra 25 or 50 basis points over a 30-year mortgage, based on a 30-year mortgage rate, that's not the impediment to people buying houses. It's the large down payments that they have to make, and it's the fact that the overall payment is so high." — Ira Jersey
He extended it to a bigger cut in rates: "Like I said, an extra 50 or even 100 basis points lower mortgage rates not going to all of a sudden mean that everyone in the world can afford a mortgage."
6. The Yen Move Is Joint
With about a minute left, Masser turned to the Treasury Secretary's stance on the Japanese currency and what it means for traders who have lived with the carry trade.
Jersey's first correction was that this is not one man's position: "Well, it's not only him"
Currency intervention runs through finance ministries acting together, in his description: "Oftentimes, you have ministries of finance, which in our case is the Treasury Department. They coordinate efforts in order to intervene in markets," and "Secretary Bessent wouldn't be doing this unilaterally if the Ministry of Finance in Japan wasn't doing the same thing"
The direction has simply reversed after years of the opposite trade
"And look, for a very long time, the Japanese were buying U.S. Dollars in order to keep the yen artificially low when it would have been strengthening. And now they're just going in the other direction." — Ira Jersey
Japan's Treasury holdings are the ammunition for exactly this: "The reason why they have a trillion dollars of Treasuries and the Ministry of Finance owns so many T-bills is because they need to use them at times like this when their currency is very weak and they want to go the other direction. Completely normal types of things in my view."
Bonus Insights
Masser reached for a gunfight comparison to describe the mismatch between the buyback's size and the job it is being asked to do, and Jersey took the metaphor further into caliber, which is where the BB gun line came from
Jersey said interest rates and their effect on households are "obviously not my bailiwick," marking the limit of what he was willing to claim before he answered anyway
Masser closed by complaining that Jersey had got through a whole segment without a Planet of the Apes reference, a running joke on his appearances
Jersey's bottom line is that the Treasury cannot buy long-term yields down at this scale, and that at 5% to 6% nominal growth it should not expect to.
