THE EQUITY RISK PREMIUM HAS VANISHED. WHAT THAT DOES AND DOES NOT TELL US.

The S&P 500 trades at approximately twenty times forward earnings. Invert that and you have an earnings yield of roughly 5.0% — the profit attributable to each dollar invested in the index over the next twelve months. The ten-year Treasury yields approximately 4.74%. The difference between those two numbers is about a quarter of one percentage point, against a long-run average somewhere between three and four points.

On the simplest reading, that quarter point is the compensation an investor receives for accepting the entire risk of owning American corporate equity rather than lending to the government that issues the currency. It is a striking number, and it has attracted a great deal of commentary this year, most of it bearish.

How the Gap Closed

It is tempting to read this as a story about expensive equities. It is not, or at least not principally. Both ends of the comparison moved, and the bond end moved further.

On the equity side, the multiple has actually compressed this year. The forward P/E stood near twenty-two in January and sits at twenty today, despite an index roughly twelve percent higher, because second-quarter earnings were exceptional and estimates were revised upward faster than prices rose. On any conventional reading, equities became modestly cheaper in 2026 while going up.

The bond side is where the change occurred. At the start of the year, consensus expected the Federal Reserve to continue cutting and the ten-year to settle near four percent. Instead the conflict involving Iran disrupted transit through the Strait of Hormuz and drove energy prices sharply higher, headline inflation has held above three percent, the Federal Reserve has not cut once, and three regional presidents dissented in July in favour of an increase. Federal debt passed forty trillion dollars, the Treasury has doubled its long-maturity buybacks in an effort to contain financing costs, and a substantial volume of artificial-intelligence-related corporate issuance has arrived to compete for the same duration buyers. The ten-year yields 4.74% and the thirty-year sits above 5.20%, the highest since 2007.

The premium did not disappear because investors bid equities to absurdity. It disappeared because the alternative improved while equities merely kept pace.

The Bearish Reading

The concern is straightforward and worth stating in its strongest form. When the premium is wide, an investor is being paid to absorb error: earnings can disappoint and multiples can compress while the starting valuation converts what would have been a loss into a period of flat returns. When the premium is a quarter of a point, that cushion is absent. Every component of the expected return depends on earnings arriving as forecast.

The arithmetic runs in one specific direction. If the ten-year yield moves sustainably above five percent — an outcome a majority of surveyed institutions now expect before year-end — the forward multiple need not fall because anything has gone wrong with corporate America. It falls because the discount rate applied to those earnings has risen. A compression from twenty times to eighteen times, which would still leave equities near their ten-year average valuation, implies an index decline of roughly ten percent with earnings entirely intact.

Our monetary policy framework had anticipated more balanced FED views, with three regional presidents dissenting in favour of an increase in July. We expected one further 25 basis point cut and a terminal rate of 3.25–3.50%. The target range has been held at 3.50–3.75% at every meeting this year. Medium-duration, high-quality paper with the 10-year near 4.0% was the view; the 10-year now yields approximately 4.74% and the 30-year sits above 5.20%, levels last seen in 2007.

The Case That It Does Not Matter

That argument has been available all year, and acting on it would have been costly. The premium was already compressed to under half a point in the spring; an investor who reduced exposure then would have forgone a substantial subsequent gain. Before treating the measure as authoritative, four objections deserve a fair hearing.

First, the comparison is theoretically unsound, and this is the most serious objection. An earnings yield is a claim on a real, growing stream of profits. A Treasury yield is a fixed nominal coupon. Subtracting one from the other conflates inflation with real growth, and in a period when headline inflation is running above three percent the calculation is biased against equities by construction. The spread looks alarming partly because inflation is elevated, which is not the same thing as equities being expensive.

Second, the measure ignores growth entirely. A five percent earnings yield attached to a stream that consensus expects to grow by nearly fourteen percent next year is not economically equivalent to a fixed 4.74% coupon, and no allocator would treat them as equivalent in practice. Over any horizon beyond a few years, the growth term dominates the starting yield.

Third, the metric has a genuinely poor record as a timing device. Its low point of the modern era came at the end of 1999, roughly three months before the dot-com peak. On a trailing earnings basis it was negative through most of the 1980s and 1990s, two of the finest decades in the history of American equity ownership. Its highest readings arrived during the global financial crisis, immediately before equities halved. It has been a reliable indicator of very little.

Fourth, the risk-free asset is not risk-free in this regime. A 4.74% nominal yield against headline inflation above three percent is a thin real return, and if inflation re-accelerates the government bond is the asset that loses purchasing power with certainty. Over long horizons equities have been the more dependable defence against precisely the fiscal and inflationary dynamics that caused this spread to compress in the first place.

What We Take From It

We do not believe the compressed premium justifies reducing equity exposure, and our published base case for the year remains constructive. We do believe it changes how that exposure should be held.

Position sizing carries more weight than security selection when there is no valuation cushion. We construct portfolios so that a twenty-five to thirty percent drawdown in the most crowded segment of the market is survivable rather than fatal, and we assess scenario-weighted drawdown potential alongside expected return for every holding. This is ordinary discipline; it simply matters more now.

Short-duration government exposure has stopped being a residual and become a genuine competitor for capital. When the two-year note yields more than four percent, holding short-dated paper is an allocation decision rather than an admission of indecision. We take yield at the front and intermediate part of the curve while declining term premium risk beyond it.

We prefer businesses whose earnings do not require a benign rate environment to arrive: durable competitive positions, free cash flow that survives capital expenditure rather than being consumed by it, balance sheets that do not need to refinance into a rising long end. In a market where the discount rate is the principal variable, the quality of the cash flow being discounted is what separates outcomes. This holds whether the bearish or the benign reading of the premium proves correct, which is the main reason we favour it.
