Start with the carry. A 10-year at 4.78% sitting 115 basis points above the effective federal funds rate implies an overnight rate near 3.63% [1][2][12], which means a buyer funding at the overnight rate is paid 115bp a year to hold the note before taking any view at all on direction [17], and that is normally the setup in which levered money crowds the long end until the spread closes. Wolf Richter's account in Wolf Street is that some of that money has been nibbling and the new supply keeps arriving anyway [8]. If he is right, the number worth noting is that positive carry has not been enough to absorb the issuance, more than the yield itself.
Bessent's side of this is harder to score than either camp allows. He has made three attempts to bring the 10-year down, which Richter calls hocus-pocus shows, and Bessent has said they may have helped keep a lid on long-term yields, a claim Richter answers by conceding that nobody knows where the yield would otherwise be [5]. The record includes no size and no measured yield response for any of the three, so "the interventions failed" and "the interventions are the only reason this is 4.78 and not higher" remain equally untestable. The 80bp of increase since the Fed began cutting needs no counterfactual [3].
The 30-year is the cleaner instrument for the argument, because there is no round number where the buyers gather. It closed Friday at 5.24%, a two-decade high and above the level it printed on October 23, 2023 [4], which leaves 46bp between it and the 10-year [14]. The 10-year's 5% line has a history of behaving like a standing bid: in 2023 the yield reached 5.02% intraday after a 170bp run in six months, 19bp came back out within the same day, and two months of decline followed [6]. That earlier run covered more than twice the ground, 170bp against 80bp, that the market has taken to get here [15], which is the difference between a stampede and a grind, and the grind is the harder one to reverse because it never exhausts the sellers.
Here is the reading the evidence supports, without proving it: the long end is pricing supply and inflation on its own clock, since two cuts have been met with a higher 10-year [3], and Friday's 4.78% sits 6bp above the top of the 4.62% to 4.72% band that held for two months [1][7][16]. What would break that reading is a rerun of October 2023. If the 10-year touches 5%, the bid shows up, and 20 or 30bp comes back out over the following weeks, then 5% is a clearing price rather than a destination, and the 22bp still to travel [13] is the entire story. A cooling inflation print that pulls the long end down alongside the policy rate would do the same damage.
For anyone setting a hurdle rate, the historical note is the load-bearing part. Above 5% was the norm before 2008 and QE, nearly always above 5% from the mid-1960s to the Dotcom Bust recession, and as high as 15% [9], and the 10-year did not drop below 4% until the Fed began QE in 2008 [11]. Richter's own view is that the economy did fine with a 10-year at 5% to 8%, the 1990s included, amid a tight labor market and growth [10]. Discount rates under 4% were manufactured, and the capital plans built on them were priced off a policy choice.
