The bond market is getting all the attention these days, and according to Mike Santoli’s latest Market Memo on CNBC, there’s a good reason why. Yields have climbed to multiyear highs as governments and companies alike flood the market with debt, and the red-hot AI buildout is soaking up capital at a staggering pace—some $2 trillion is being directed into new computing capacity by the end of next year.
That surge in borrowing costs hasn’t done much to cool corporate investment, but it could start to bite in other corners of the economy, like housing and consumer spending. Last week, Treasury Secretary Scott Bessent expanded a program to buy back small amounts of less-liquid government debt in the open market, a move aimed at restraining longer-term yields. The reaction was swift and loud, with critics calling it either an inappropriate attempt to massage rates or too small to matter—or both.
The criticism only grew after the initial dip in yields reversed a day later, while the dollar fell and gold jumped—a combination some read as a vote of no confidence in the stewards of financial policy. And, of course, the bond selloff reignited fears about a fiscal breakpoint, the kind of worry that flares up under stress and then often fades.
Putting the Move in Perspective
But Santoli urges some perspective. The 10-year Treasury yield rose just 4 basis points last week, to 4.74%. It’s been at these levels a few times over the past three years, if only briefly. Meanwhile, the yield on investment-grade corporate debt remains below its peak from a few years ago, because credit spreads are so tight. In other words, the absolute level of yields isn’t broadly punitive for big companies yet, and it’s not acting as a strong undertow pulling down equity values.
With nominal GDP growth running near 5–6%, he asks, how much lower would you expect 10-year yields to be? The yield curve’s steepness is also within historical ranges, and the move in bonds has been orderly enough that the stock market has held up relatively well.
Still, textbooks say the cycle high in real yields—the 30-year real yield now exceeds 3%—should eventually restrain growth and valuations. Those effects can be subtle and slow to show up, especially when corporate growth is as exciting as it is right now.
A Market Living in the AI Kitchen
Santoli points out that the S&P 500 has been living quite comfortably in that same sweltering AI kitchen. About a third of recent earnings growth comes directly from AI infrastructure companies. The index is more of a capital-goods, business-to-business benchmark than a gauge of broad U.S. consumption—consumer discretionary makes up just 9.2% of the S&P, and that drops below 4% if you exclude Amazon and Tesla.
That helps explain why the market is hovering within a couple of percent of record highs even as July housing starts fell 12.4% and Walmart posted its weakest quarterly same-store sales growth since 2020. The economy isn’t struggling broadly—consumer spending is stable, unemployment is low, and debt-service burdens are manageable—but wage growth is sagging while inflation stays elevated. The real juice is coming from corporate spending, a capital-over-labor dynamic that makes rising rates an affordability issue rather than a sign of household strength.
Bonds Getting Interesting?
For investors, the same rise in real yields that raises the hurdle rate for borrowers also means better compensation for bondholders. Is value building in bonds just as conventional wisdom turns against them as a diversifier?
Barry Knapp of Ironsides Macroeconomics thinks there’s room for a countertrend rally in long-dated Treasuries, even though he remains a secular bond bear and doesn’t see Bessent’s actions as a major catalyst. The latest climb in yields has come despite softer inflation and employment data, which he says leaves scope for a bounce.
Equity investors are watching closely. The S&P 500 slipped 1.4% last week, with semiconductor stocks down more than 5% and banks off 4%. Industrials lost over 3%. Rick Bensignor of Bensignor Investment Strategies sees tech peaking in relative terms and prefers healthcare and financials, flagging a cautionary note if Nvidia’s results don’t bring new buying. John Kolovos of Macro Risk Advisors notes sentiment has jumped, and with implied volatility low, he’s been advocating tactical VIX call spreads as insurance despite a bullish overall forecast.
Santoli also draws a parallel to the 1960s computer-leasing boom, where the logic of “practically infinite” demand and circular financing sounded eerily familiar. Then, as now, the market’s bet is that the growth story outpaces the cost of capital. So far, it has. But the bond market is reminding everyone that the kitchen is getting hotter.
