Ask economists what the most important U.S. asset class is, and they’ll likely tell you bonds. Treasury Secretary Scott Bessent has said the same. Across Wall Street, one of the first orders of an analyst’s day is to check the performance of longer-term Treasuries and the yields on them, which indicate investors’ perceptions of risk.
For good reason: As well as acting as a temperature check for the economic outlook, the yields on longer-term Treasuries, such as 10- and 30-year bonds, provide lenders with a benchmark for consumer interest repayments, compared to the low-risk asset of government borrowing. As such, these yields are reflected in the rates offered to borrowers elsewhere in the economy—think houses, cars, and credit cards—influencing the financial decisions of businesses and consumers.
10-year Treasury yield performance has been increasingly bumpy recently: This year alone, lows have hit 3.96% with highs of 4.66%. The 30-year has gone as low as 4.54% and as high as 5.18%. Those are all big moves for U.S. bonds.
Warsh’s fresh thinking at the Fed is likely to undo investors’ habit of focusing on the long end, according to Morgan Stanley’s Jim Caron. Investors will still take note of Treasury moves, but volatility should be watched at the short end of the curve (a year or two), rather than at the long end (10- and 30-year Treasuries).
This is entirely by design, Caron told Fortune, owing to Warsh’s highly scrutinized task force strategy. The new Federal Reserve chairman has asked for fresh thinking on the quality and timeliness of data, potentially meaning the Fed will collect more real-time data rather than relying on backdated surveys.
Likewise, Warsh has outlined the beginnings of a new communication strategy, one without the forward guidance that previously signaled to markets the path interest rates may take over the longer term.
The combination of more reactive Fed policy in the short term, and a less forthcoming central bank over the longer term, may result in more volatility in short-term bonds (which are more directly impacted by the base rate set by the central bank) and a smoothing at the longer end of the yield curve.
Caron, Chief Investment Officer of portfolio solutions at Morgan Stanley, explains: “The way that I’ve interpreted it is that if [Warsh] is gonna be more variable in terms of his views because he wants to be more contemporaneous and more real-time in his thinking, then that means that the front end of the yield curve is going to be more volatile.
“But if he does his job, if the Fed does their job—and that is indeed a better way to go—then what should be true is that the front end will gain volatility, but then it will lose volatility in the longer run, like at the 10-year point and beyond, because basically what they’re saying is that they will address the situation in more real time.”
Conveniently for Warsh, if the potential plan pans out, it addresses the central bank’s oft-forgotten third aspect of its mandate: Moderate long-term interest rates.
“So let’s say inflation’s heating up,” Caron says as an example, “[Warsh] may become more hawkish earlier, and that’ll tamp down that inflation. Now that’ll be very volatile for the two-year note, but the 10-year note will have less volatility.
“What that could ultimately mean—if it all works well—is when you think about corporate borrowing rates, when you think about a homeowner for a mortgage, these tend to be at the longer end. These tend to be 5-year, 10-year, longer term. So if you can stabilize the volatility in the longer end by addressing the higher frequency of data in the shorter end … it could be a really good thing.”
Rethinking investment habits
If pricing in policy speculation and risk happens at the longer end, then investors may want to adjust their habits. Caron said: “You do want to pay much more attention to those short-term interest rates, versus opening up your screens and saying, ‘Where’s the 10-year, where’s the 30-year?'”
Investors, to some extent, already know the short rate because they’re aware of central bank policy around the world, but Caron added, “I would think about the front end of the yield curve as the shock absorber for the back end of the yield curve. The task force hasn’t come out, this is my interpretation of everything, that’s the way I would think about it.”
The suggestion that Warsh may move hawkish or dovish in line with the data may not be popular with President Trump, who has lobbied since he entered the Oval Office for a lower base rate.
It would be a mistake to expect Warsh, in any fashion, to come out as a committed dove. Caron described that idea as “low-resolution thinking.” He added: “Any economist that’s looked at the Fed can’t paint Kevin Warsh as dovish or hawkish. He’s been on both sides of this whole thing.”
