JPMorgan issued a note this week highlighting a notable decline in the equity risk premium - the additional return investors expect for holding stocks over bonds. Strategist Nikolaos Panigirtzoglou estimates that the S&P 500 equity risk premium now sits at about 2.1%, a level JPMorgan says is the lowest since 2002.
The bank attributes the compression of the premium to two forces operating this year: an extended rally in equities and a sharp increase in real bond yields. According to JPMorgan's calculations, the current estimate is roughly 100 basis points below long-run historical averages and has fallen beneath the prior cycle low of 2.4% recorded in 2007.
Panigirtzoglou set out three implications arising from the reduced premium. First, he warned that equities could become more responsive to moves in bond yields, likening the potential regime to the 1974-to-1998 period of low risk premia. In his words: "Going forward equity markets could exhibit higher sensitivity to bond yields than the one exhibited over the past couple of decades."
Second, the strategist argued that a smaller equity risk premium strengthens the case for bonds within long-term asset allocation frameworks. JPMorgan's own metrics indicate that non-bank investors, along with G4 pension funds and insurers, are the most overweight equities relative to bonds since 2002. The bank said that such positioning could prompt more substantial rebalancing into bonds if real rates continue to drift higher.
Third, Panigirtzoglou expects the shift to reinforce the positive correlation between bonds and equities that appeared in 2022 following the inflation shock. He noted that this dynamic presents a persistent headwind for the so-called "risk parity trade," which relies on bonds as a hedge against equity risk, and could increase demand for direct equity hedges such as put options.
The note frames these outcomes as interrelated: lower risk premia driven by stronger equity prices and higher real yields make portfolios more sensitive to rate movements, encourage a rebalancing toward fixed income where investors are heavily underweight, and sustain a bond-equity relationship that complicates traditional hedging strategies.
Clear Summary
The S&P 500 equity risk premium has declined to about 2.1% on JPMorgan's estimates, the lowest since 2002. This change - propelled by an equity rally and rising real yields - implies greater equity sensitivity to bond yields, a case for increased bond allocations among heavily equity-overweight investors, and continued pressure on risk parity strategies plus likely greater use of direct equity hedges.
Key Points
- Equity risk premium estimated at roughly 2.1%, about 100 basis points below historical averages.
- Potential market effects include higher equity sensitivity to bond yields and increased appeal of bonds for long-term allocation, affecting asset managers, pension funds, and insurers.
- The evolving bond-equity correlation presents challenges for risk parity strategies and could raise demand for equity puts.
Risks and Uncertainties
- Higher sensitivity of equities to bond yields - could increase volatility for equity-heavy portfolios, particularly those exposed to rate moves.
- Large overweight in equities by non-bank investors, G4 pension funds, and insurers - may trigger pronounced rebalancing into bonds if real rates continue upward, affecting equity markets.
- Reinforced positive bond-equity correlation - poses a sustained headwind to strategies that use bonds as equity hedges, pressuring risk parity allocations.
