Rising bond yields are once again pressuring portfolios, and a negative equity-bond correlation regime may persist

Overview

This report is a global cross-asset and fixed income strategy study focused on how rising bond yields affect equities, bonds, and balanced portfolios. Goldman Sachs points out that recent upside inflation surprises in the United States and resilient activity data have made the macro backdrop more reflationary, triggering a selloff in global long-duration bonds. Market responses to higher yields are currently closer to an inflation and monetary policy shock than to a pure growth improvement, so the equity-bond yield correlation has turned sharply negative and portfolio diversification has been challenged.

Core views

The report's core view is that the impact of higher rates on equities depends on the source, speed, and starting level of the yield move. Growth-driven yield increases are usually buffered by earnings and growth optimism; inflation-driven or monetary-tightening-driven yield increases are more likely to weigh on equity valuations. Even when the source of the yield move is relatively benign, if the move is too fast or disorderly, it can become a headwind for equities. Goldman therefore keeps bonds neutral while recommending hedges through option structures that benefit from equity declines and rising rates.

Analysis framework

The report uses frameworks such as cross-asset correlations, yield levels, real rates, growth expectations, volatility, risk premia, and option pricing to compare the linkage between equities and bonds under different types of macro shocks. The analysis focuses on the short-term correlation between US equities and the US 10-year yield, the relative volatility of the PC1 "global growth" and PC2 "monetary policy" factors, front-end inflation pricing versus forward inflation pricing, and the historical payoff profile of different hedging tools under rate shocks.

Methodology notes

• Cross-asset correlationEquity returns and bond yield correlation

  Use the correlation between equity returns and changes in bond yields to judge the direction of the rate shock's impact on portfolios.

  The report notes that the 2-month correlation between US equities and the US 10-year yield has dropped to its most negative level since the late 1990s, suggesting that yield increases are more likely to be interpreted as inflation or monetary policy pressure by the market.

• Macro factor decompositionPC1 "Global Growth" and PC2 "Monetary Policy" factors

  Use the relative volatility of growth and monetary policy factors to distinguish the source of the shock behind rising yields.

  The report says that since the Middle East war and the energy price shock, markets have focused more on inflation and monetary policy shocks, while the relative volatility of PC1 "global growth" versus PC2 "monetary policy" has declined, alongside a more negative equity-bond yield correlation.

• Interest rate constraint indicator10-year real rate vs long-term real GDP growth expectation gap

  Compare 10-year real rates with consensus long-term real GDP growth expectations to judge whether monetary policy is too tight.

  The report notes that when the 10-year real rate is above long-term real GDP growth expectations, monetary policy is usually tighter and more challenging for equities. Current long-term real GDP growth expectations are about 2.1%.

• Derivative hedgingEquity downside / higher rates double-digital mixed structure

  Use an option structure that benefits from both equity declines and higher rates to hedge further rate shock-driven equity selling.

  The report believes that 3-month 25-delta put/call options and double-digital mixed structures are attractive in a further rate shock scenario, especially as an overlay hedge for balanced portfolios.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Bonds

  The report's core asset and the direct transmission channel of higher-yield shocks.

  Strengths

  Bond attractiveness has improved from a risk-premium perspective.

  Weaknesses

  Global long-duration bonds have already sold off amid the reflation backdrop and spillover shocks, and the negative equity-bond correlation regime may persist.

  Comparison

  Relative to equities, bonds are more directly exposed to rising yields; however, their risk premium is relatively more attractive at higher yield levels.

  Risks

  Inflation surprises, hawkish central bank messaging, spillovers from UK and Japan rates, and a further rapid rise in the US 10-year yield.

• Equities

  Affected by the source, speed, and starting point of higher bond yields.

  Strengths

  If higher yields are driven by stronger growth, equities can be buffered by growth optimism and earnings expectations; the report also notes that micro catalysts such as AI investment have supported share prices since April.

  Weaknesses

  If higher yields are driven by inflation or monetary policy, discount-rate pressure is greater and the equity-bond yield correlation turns negative.

  Comparison

  Compared with bonds, equities are more resilient to growth-driven rate increases; however, they are more sensitive to inflation and real-rate shocks.

  Risks

  Disorderly yield increases, real rates above long-term growth expectations, and front-end inflation pricing pushed higher by energy prices.

• Balanced portfolios

  Affected by the combined pressure on both equities and bonds.

  Strengths

  Can use a double-digital structure that benefits from equity downside and higher rates as a targeted overlay.

  Weaknesses

  When equities fall and yields rise at the same time, the diversification benefit of a traditional equity-bond portfolio declines.

  Comparison

  Compared with single-asset portfolios, balanced portfolios depend more on the stability of negative equity-bond correlation; the current environment weakens that mechanism.

  Risks

  Persistently negative equity-bond correlation, right-tail rate risk, and elevated hedging costs and option-implied correlation pricing.

• Options and double-digital mixed structures

  Recommended by the report as a hedge against equity downside under further rate shocks.

  Strengths

  Can target the combined risk of equity declines and rising yields, serving as a coverage tool for balanced portfolios.

  Weaknesses

  Option prices and volatility are indicative estimates, and trading costs and structural complexity may be high.

  Comparison

  Compared with directly reducing risk assets, option overlays can preserve some upside participation, but require paying premium and accepting pricing risk.

  Risks

  Divergence between implied and realized correlation, path risk before expiration, liquidity constraints, and trading costs.

Key data

• Report date2026-05-18The cover shows Portfolio Strategy Research, with publication at 9:00 PM BST.
• Asset allocation viewNeutral on bonds for 3M/12MThe report says it is still maintaining a neutral bond allocation in asset allocation, even though bonds look more attractive from a risk premium perspective.
• Equity-bond correlation2-month correlation is the most negative since the late 1990sThe 2-month correlation between US equities and the US 10-year yield has turned sharply negative.
• Key yield thresholdsUS 10-year yield above 5%; real yields above 2%-2.5%Historically these ranges were associated with more negative equity/bond-yield correlation, but the report argues this metric is weaker than the real-rate versus long-term growth expectation gap.
• Long-term real GDP growth expectationAbout 2.1%The report compares this with the 10-year real rate to judge the degree of policy constraint.
• Recent rate volatilityUS 10-year yield rose by more than 2 standard deviations in a single weekThe report treats this as a reminder not to dismiss right-tail rate risk too early.

Impact & implications

For portfolios, traditional equity-bond diversification may fail in an environment dominated by inflation and monetary policy shocks. A rapid rise in yields not only pressures bond prices, but can also weigh on equities through the discount-rate channel and risk appetite. The report's view on bonds is not a turn to bullishness; rather, it emphasizes that improved risk premia coexist with correlation risk. For balanced portfolios, it is more important to manage the combined risk of higher rates and equity downside through targeted option overlays.

Risks

• Inflation data continues to come in above expectations, causing markets to interpret rising yields as monetary policy pressure.
• The US 10-year yield rises quickly and disorderly, triggering equity valuation pressure.
• The 10-year real rate moves above long-term real GDP growth expectations, signaling a tighter policy environment.
• Volatility in the UK and Japanese bond markets spills over into global rates markets.
• An energy price shock pushes front-end inflation pricing higher, deepening the negative correlation between equities and rates.
• Options and double-digital mixed structures carry premium loss, liquidity, trading cost, and model-pricing risks.

What to watch

• Speeches by Federal Reserve officials, especially Waller, Barr, Paulson, and Barkin.
• European inflation data and preliminary PMI readings.
• Whether the US 10-year nominal yield approaches or breaks 5%.
• Whether the 10-year real rate continues to stay above the long-term real GDP growth expectation of about 2.1%.
• The divergence between front-end inflation pricing, energy prices, and forward inflation expectations.
• Whether the short-term correlation between equities and bond yields remains in an extreme negative range.
• The gap between option-implied equity-bond yield correlation and realized correlation.
