- The equity risk premium (ERP) — the gap between the S&P 500’s earnings yield and the 10-year Treasury yield — has nearly disappeared, hovering at its lowest levels since the early 2000s as bond yields surge and stock prices stay elevated despite stretched valuations.
- The 10-year Treasury yield settled at 4.57% Friday, up from 3.96% just before US and Israeli strikes on Iran in late February, while the S&P 500’s forward earnings yield has declined as share prices rallied — compressing the premium investors get for taking equity risk over holding safe government debt.
- The last time the ERP dipped below zero for an extended period was after the dot-com bubble burst; strategists note stocks are essentially promising only marginally higher returns than ultrasafe Treasuries at current price levels.
- Equity bulls argue the AI earnings boom justifies the stretched premium, while bears counter that sustaining current valuations requires years of exceptional earnings growth — and that oil prices and Fed policy uncertainty could derail both conditions simultaneously.
What Happened?
A global bond selloff driven by Iran war inflation fears has pushed Treasury yields sharply higher, while stock markets simultaneously rallied on AI optimism and deal hopes — creating a rare convergence in which the return from holding safe government bonds is nearly equal to what equities promise. The equity risk premium has nearly zeroed out, with the S&P 500’s forward earnings yield declining as share prices jump while the 10-year Treasury yield has risen 60 basis points since the Iran war began. Mercer Advisors’ Don Calcagni called it “a little bit of a disconnect between the bond market and the equity market,” warning that inflation fears are growing while valuations are stretched.
Why It Matters?
Historically, periods of very low or negative ERP have preceded subpar equity returns relative to bonds over multi-year horizons. The current setup means investors are accepting near-bond levels of expected return for the volatility and downside risk of equities. That trade is only rational if AI-driven earnings growth delivers sustained upside that bonds cannot match. LPL Financial’s Jeff Buchbinder framed the key test plainly: “Lower rates, more earnings — if we don’t get both those things, then this stock market looks expensive.” He also calls oil prices the “chart of truth” for negotiations: “If we’re still looking at $100 oil in late summer, then the formula changes.” The PCE inflation data and retail earnings due this week provide early reads on both variables.
What’s Next?
Near-term catalysts include consumer confidence data, Costco and Dollar Tree earnings, and the Fed’s preferred PCE inflation gauge. A further escalation in Treasury yields — driven by fiscal concerns, Fed hike pricing, or a delayed Iran deal — would widen the bond-equity disconnect further and increase the probability of a valuation correction in equities even if the macro backdrop does not deteriorate. Neuberger’s Jeff Blazek offered the bull case: “Stocks aren’t cheap, but they’re not horribly expensive” — contingent on the Fed staying softer than the market fears. Nobel economist Robert Shiller’s excess CAPE yield, which has a century-long track record of predicting forward equity-over-bond returns, is flashing a warning that few in the current rally are heeding.
