Do bonds move inversely to stocks?

Lead

Do bonds move inversely to stocks? Historically bond prices have often risen when stocks fell and vice versa, but this negative correlation is conditional and can reverse. This article explains the mechanics behind the apparent inverse move, reviews empirical patterns and notable episodes (including July 2025 Treasury moves), and outlines practical implications for investors and portfolio construction.

Background and definitions

Bonds and bond prices

A bond is a debt contract issued by a government or corporation; bond prices move inversely to yields — when yields fall prices rise, and when yields rise prices fall.

Stocks (equities)

Stocks are ownership claims on companies; their returns come from earnings growth and changes in valuation (multiples), and they react to growth, risk appetite and discount rates.

Correlation and related metrics

Correlation measures co-movement between two assets (from −1 to +1). Practitioners also use rolling correlations and beta estimates — for example bond beta to equities — to quantify how bonds move relative to stocks over time.

The textbook/investor intuition for an inverse relationship

Investor risk preference and portfolio flows

The classic story: in risk-off periods investors rotate from equities into high-quality bonds (a flight to safety). That shift increases bond prices and pushes down stock prices, producing an inverse relationship between the two asset classes.

Interest rates and discounting

Lower interest rates reduce discount rates used in valuing future cash flows. That makes both long-duration bonds and the present value of equity cash flows more attractive, so an easing cycle can lift bonds and equities through different channels.

Opportunity-cost argument

Bonds and stocks compete for finite savings; when bonds offer relatively higher real returns they can draw capital away from equities and vice versa.

Economic and market mechanisms that drive the relationship

Monetary policy and rate expectations

Central banks alter short-term policy rates and shape expectations for the path of rates. Rate cuts lower yields and can support both bond prices and equity valuations; rate hikes raise yields, increase discount rates and can pressure stocks. Expectations about future policy frequently drive asset re-pricing before policy changes arrive.

Inflation and real rates

Real yields (nominal yields minus inflation expectations) matter for both bonds and equities. Rising inflation that pushes up real yields can hurt bond prices and reduce the present value of equities, potentially turning a normally negative correlation into a positive one.

Growth vs. inflation regimes

The stock–bond relationship is regime-dependent. In growth-scare episodes (slowing growth, stable inflation), high-quality bonds often hedge equity losses. When inflation dominates or stagflation risks rise, both bonds and stocks may fall together.

Duration and term structure

Sensitivity to rate moves depends on bond duration and maturity. Long-term Treasuries typically show larger price moves for a given change in yields than short-term bills; corporate bonds also embed credit risk that can align their moves with equities.

Empirical evidence and historical patterns

Long-run patterns and regime shifts

Empirical studies find the stock–bond correlation is not static. Over decades it has swung from negative to positive in different periods. Rolling-correlation analyses show extended intervals of negative correlation separated by episodes where correlation rises toward zero or positive territory.

Recent examples and notable episodes

A clear recent example: in 2022 both stocks and bonds fell as central banks tightened rapidly to combat inflation. More recently, as of July 2025, the US 10-year Treasury yield spiked to 4.27%, exerting downward pressure on risk assets including equities and crypto. That episode highlights how rising yields tied to macro and geopolitical dynamics can push bonds and stocks lower at the same time.

Research findings and sources

Academics and industry researchers use rolling windows and regime-switching models to show that inflation surprises, real-rate moves and liquidity shocks explain much of the time-variation in the stock–bond correlation.

When bonds do not act as an inverse hedge

Inflation-driven selloffs and stagflation

When inflation rises materially and real yields increase, both bond prices and equities can decline together. Supply shocks or stagflation reduce corporate profit prospects while increasing required yields, defeating the usual negative correlation.

Rising yields from improved growth expectations

If improved growth expectations drive higher yields (and stronger earnings), equities may rise while bond prices fall; the correlation can be positive or ambiguous depending on the balance between valuation multiple expansion and discount-rate effects.

Credit risk and corporate bond behavior

Corporate and high-yield bonds embed credit risk and tend to move more like equities when credit spreads widen. In stress episodes, corporate bond prices often fall with equities even as Treasuries rally as flight-to-quality occurs.

Practical implications for investors and portfolio construction

Diversification and the 60/40 paradigm

Historically, a negative correlation between stocks and high-quality bonds supported the long-standing 60/40 equity–bond allocation. But when correlations shift, the diversification benefit can shrink, requiring investors to reassess tail-risk and rebalancing plans.

Tactical responses and hedging

Practical approaches include: adjusting duration (long-duration Treasuries can hedge equity risk when growth concerns dominate), adding inflation-protected securities (TIPS) when inflation risk is rising, diversifying across credit quality and maturities, and using alternative hedges such as volatility strategies or non-correlated assets. For crypto and digital-asset investors, monitor how traditional bond yield moves influence risk asset valuations and consider custody or wallet solutions like Bitget Wallet for secure asset management.

Measuring and monitoring correlation risk

Track rolling correlations, the term structure, inflation breakevens and central bank guidance. Regularly stress-test portfolios across different macro scenarios to understand how the equity–bond relationship might change.

Measurement and tools

Key metrics to track

Useful indicators include the 10-year Treasury yield (a global benchmark), the yield curve (term spreads), breakeven inflation rates (nominal minus real yields), equity volatility measures (e.g., VIX), and rolling correlation windows (30-, 90-, 252-day) to capture evolving co-movement.

How practitioners estimate bond beta to equities

Analysts commonly run regressions of bond returns on equity returns to estimate bond beta to equities. Caveats: betas are time-varying, sample- and window-dependent, and sensitive to regime changes and outliers.

Common misconceptions and caveats

“Always inverse” is false

The statement that bonds always move inversely to stocks is false — it is a conditional tendency, not an immutable rule.

Different bonds behave differently

Government Treasuries, corporates and municipals differ in liquidity, credit exposure and duration — they do not move as a single block.

Short-term noise vs long-term relationships

Short-term episodes can deviate sharply from long-run tendencies. Investors should distinguish between transient volatility and structural regime shifts.

Empirical vignette: July 2025 market context

As of July 2025, according to a market report, the US 10-year Treasury yield rose to 4.27%. That climb created meaningful headwinds for risk assets. The rise in the 10-year yield increased global borrowing costs, pressured valuations across growth-sensitive sectors, and contributed to declines in risk assets including certain equities and cryptocurrencies. The episode underlined that rising nominal and real yields tied to macro and geopolitical developments can drive bonds and stocks in the same direction for sustained periods.

Key observable impacts in that episode included: rising yields pulling capital into government debt, higher discount rates re-pricing future earnings (negative for long-duration stocks), stronger dollar dynamics that pressured dollar-denominated risk assets like Bitcoin, and elevated market volatility. On-chain indicators during the selloff showed higher exchange inflows for older cryptocurrency holdings and negative futures funding rates, consistent with deleveraging behavior.

Summary / Conclusion

Bonds often—but not always—move inversely to stocks. The relationship depends on monetary policy, inflation and real-rate moves, growth expectations, bond type and maturity, and market liquidity. Investors should treat the inverse relationship as a conditional tool, monitor key indicators (10-year yield, breakevens, vol, rolling correlations), and consider duration, credit, and inflation-protected allocation tweaks.
