This Time Would Have To Be Very Different

Hanno Lustig The Two Cents

At 40.7, CAPE is nearing its December 1999 peak of 44.2. For the S&P 500 to beat TIPS over the next decade, today’s near-record P/E multiple must persist for ten years, or real earnings must grow more than 5.8% a year—a pace exceeded in only two decades since 1880: the 1920s and 2010s.

The CAPE is currently trading at 40.7, which is close to an all-time high. You’re paying close to 41 times annual earnings when you buy the S&P 500. The implied earnings yield is only 2.46%. According to AQR, a reasonable estimate for real earnings growth (on a per share basis) is 1.8% per annum. If you plug in today’s numbers, you end up with a real expected return of around 3% per year for U.S. equity. That’s a surprisingly low number. When you compare it to the 10-year TIPS yield of 2.75%, you’re left with a razor-thin equity premium. The stock market will only yield an extra 25 basis points per annum over the next, say, 10 years to compensate you for taking on equity risk. You might think this is a very conservative estimate, but it’s actually not, because we’re implicitly assuming that the CAPE stays at 40.7 over the next 10 years. That’s quite a lofty multiple. Even casual eyeball econometrics suggests that that’s not a great assumption, because the price-earnings ratio tends to revert back to its mean.

The S&P 500’s cyclically adjusted price-earnings ratio stands at 40.7, close to an all-time high, implying an earnings yield of just 2.46% for buyers of the index.
Combining the 2.46% earnings yield with AQR’s estimate of 1.8% annual real per-share earnings growth yields a real expected return of roughly 3% per year for U.S. equity.
Against a 10-year TIPS yield of 2.75%, U.S. equities offer an equity premium of about 25 basis points per year, an estimate that assumes the CAPE stays at 40.7 for a decade despite the price-earnings ratio’s tendency to revert to its mean.

Circularity in AI Shows Up in Token Spending Too

According to Ramp data, 80% of firms in the top 1% of AI spending are VC-backed, compared with just 13% of firms at the median. This suggests that the largest purchasers of AI computing capacity rely heavily on venture capital rather than internally generated earnings.

Ramp data show that 80% of the top 1% of AI spenders are VC-backed, compared with only 13% of the median spender, suggesting that the circularity seen among AI hyperscalers and model providers also extends to token spending, as the startups buying the most compute are paying for it with venture capital rather than organic earnings. If the AI payoff is slow to materialize or never arrives, VC returns would come under pressure, since the capital funding today’s token spending would have little to show for it, and a pullback in venture funding could in turn weaken demand for compute.

Revenue Per Worker Is Up. Are Firms Getting a Larger Share?

Nonfarm business output per hour grew 2.2% annually between 2019 and 2025, up from 1% in 2010–19. Among public firms, growth in real revenue per worker accelerated from 0.7% to 2.2%. Operating margins rose from 16% to 18% of sales (2.4% annual growth).

A profit margin is profit divided by sales: the share of each sales dollar the firm keeps after paying its costs. The gross margin subtracts the direct cost of production (cost of goods sold), while the operating margin also subtracts overhead (selling, general, and administrative expense, which in Compustat typically includes R&D). If productivity gains were flowing to firms’ profits, margins should show it. Through the 2010s margins were flat: gross margins grew about 0.4% a year from 2010 to 2019, and operating margins were roughly flat. Both then turned up: on average, gross margins went from about 34% of sales in 2019 to 37% in 2025 (1.3% growth per year), and operating margins from 16% to 18% (2.4% growth per year). Part of the gains surfaced with wider profit margins: on a reasonable baseline, the operating margin rose over 2% a year from 2019 to 2025.

Earnings Will Be Spectacular. It May Not Be Enough

Since 2000, post-tax corporate profits as a share of GDP have trended upward across cyclical setbacks and are now near an all time high, above their 1929 level.

Throughout the 20th century, profit margins were regarded as one of the purest mean-reverting series in the economy. So far this century, however, margins have done nothing but rise. Measured with the National Income and Product Accounts, part of the GDP calculation, profits are currently taking a bigger share of the economy even than on the eve of the Great Crash in 1929. The series comes with a lag, so we can assume the profit share on this basis is comfortably at a record by now.

The Bond Market Reckoning Has Only Begun

The spread between 10-year French OATs and German Bunds has widened at a pace seen only during the eurozone sovereign-debt crisis. John Authers warns that France “satisfies all the classic conditions for a major debt crisis.”

Only in the worst days of the euro zone’s sovereign debt crisis, in 2011 and 2012, has the [spread of 10-Year French OATS over German Bunds] risen so fast. Talk of a second euro-zone crisis, this time with an epicenter in Paris, is growing, and it’s easy to see why. Why is this more of a problem for France and the UK? Beyond their deficits, they also shoulder much higher tax burdens than the US. Tax revenues are 25.2% of GDP in the US, the lowest of the major developed economies - but 35.3% in the UK and 43.9% in France. It’s hard to imagine after decades of tax-cutting, but a US politician could deal with the deficit fairly easily with a tax hike. It’s not clear that option is open to French lawmakers, even if they could somehow persuade voters to go along with them. The populist politicians of left and right, who currently look well placed in next year’s presidential elections, are in any case unlikely to try.

Foreign investors made a record $942bn in net purchases of US equities and investment fund shares in the 12 months to July, accelerating a shift in overseas investment towards American stocks and away from debt. The flows represented the highest rolling 12-month total in Treasury data going back to 1985. Net purchases of US equities and investment fund shares by foreign investors jumped to $426bn in the second quarter, up 62% from the same period in 2025, and surpassing the previous quarterly record of $299bn in 2022, according to the Bureau of Economic Analysis.

De-reservification, Not De-dollarization

The stock of global dollar reserves has been roughly stable over the past decade. The world is not moving away from the dollar: dollar assets are shifting from official holdings of Treasurys towards private and quasi-sovereign holdings of risk assets.

Most of the current flow into the US from the “official” sector is coming from investors who are not classic reserve managers. Those flows remain heavily tilted toward the dollar, at least for now. Any real de-dollarization would likely occur first among these investors. Put differently, the dollar’s global role is increasingly as a source of returns, not a source of safety. The foreign bid, private and public, is for risk, not for Treasuries. It is currently fashionable in some circles to point to the diminution of the “convenience yield” on Treasuries even while the U.S. dollar continues to enjoy such a privilege. But the shift in the global investor base and their apparent portfolio preference for U.S. risk assets in lieu of Treasuries may help explain the divergence between the convenience yield on Treasuries and the convenience yield on the USD.
