Fixed income

Beyond yesterday’s bonds: Taking a fresh look at fixed income

September 24, 2026 - 5 min

For many investors, the bond market they remember no longer exists. Years of near-zero interest rates, followed by an inverted yield curve that rewarded staying in cash, reshaped how investors think about fixed income. Yet many investors remain anchored to those conditions, maintaining elevated cash allocations and viewing bonds primarily as a defensive asset.

Today’s market tells a different story. A normalized yield curve is once again offering attractive potential rewards to investors for extending beyond cash; bond yields have become increasingly competitive with equity income; and a broader, more complex opportunity set is creating new ways for active managers to add value. The question is no longer whether investors should own bonds but whether their fixed-income allocation reflects today’s reality.

Three reasons to reconsider fixed income

  • Cash was king when the yield curve was inverted. Now, extending duration may once again be rewarded.
  • The income advantage of equities has largely disappeared. Investors can pursue yields approaching those available from stocks without taking the same level of market risk.
  • Broad fixed income offers opportunities that passive benchmarks may miss. Active managers can seek value through security selection, sector rotation, and flexible duration positioning in the current market environment.

Cash may no longer be the only answer

One of the clearest signs that investors may be anchored to the past is their continued preference for cash.

That preference made sense when the yield curve was deeply inverted and money market funds offered yields comparable to or better than longer-term bonds. Investors were being paid handsomely to stay short. Yesterday's playbook may be less effective if current conditions persist.

The Treasury yield curve has largely normalized, transitioning from an inverted structure to a more traditional upward-sloping shape. As short-term yields have declined relative to longer maturities, the compensation for remaining exclusively in cash has become less attractive.

For advisors, this scenario leads to an important client conversation. Investors who remain concentrated in money market funds may be missing a notable opportunity. Longer-maturity fixed income offers the potential to lock in more attractive yields for an extended period.

Equally important, real yields remain historically compelling. With Treasury real yields above 2% across key maturities, investors can receive a meaningful cushion against current levels of inflation while generating income levels that were difficult to find for much of the previous decade.

The key takeaway is not that investors should abandon cash entirely. Rather, the opportunity cost of remaining overly concentrated in cash has increased. As the yield curve has steepened substantially, investors once again may be rewarded for extending maturity and reengaging with duration.

Bond income is becoming more competitive with earnings yield

At the same time cash is becoming less compelling, fixed income is regaining something it lacked for years: meaningful competition with equities on income.

For much of the post-financial-crisis era, investors seeking yield had little choice but to move up the risk spectrum. Bond yields were compressed, and equities appeared to offer a superior source of return potential. That dynamic has changed.

Treasury yields have moved materially higher, while strong equity market performance has pushed earnings yields lower. As a result, the gap between the earnings yield of the S&P 500® Index and the yield available from 10-year Treasuries has narrowed substantially. Investors can now access income levels that are approaching parity with equities while assuming significantly less risk.

This scenario becomes especially relevant when viewed through a valuation lens. Several major equity indices continue to trade at valuation levels above their long-term medians. The S&P 500®, MSCI ACWI, and MSCI EAFE all rank in elevated percentile ranges relative to the past two decades. Such conditions leave investors more vulnerable to multiple compression if earnings growth disappoints, economic conditions weaken, or investor sentiment shifts.

None of this suggests investors should replace equities wholesale. Rather, it changes the relative-value equation. When investors can earn bondlike income from equities only by accepting substantially higher volatility and valuation risk, fixed income becomes a more compelling allocation. For advisors seeking to improve portfolio efficiency, that represents a significant shift in the investment landscape.

Why active management matters more than ever

The strongest case for fixed income today may not simply be that yields are attractive. It may be that the opportunity set has become increasingly diverse.

At the index level, credit spreads are historically tight. On the surface, that might suggest limited value remains within fixed-income markets. But broad market statistics often obscure what is happening beneath the surface. Sector-level and issuer-level opportunities continue to emerge, creating a more favorable environment for active security selection.

This is particularly important because passive fixed-income benchmarks are becoming increasingly concentrated.

The Bloomberg US Aggregate Bond Index has steadily increased its Treasury allocation over time. As a result, investing in core strategies that closely track the Agg have increasingly become a bet on US Treasuries. In periods when rates remain volatile but rangebound, that concentration can reduce flexibility and limit potential sources of return.

Importantly, active managers can adjust duration – a key measure of a fixed-income portfolio’s sensitivity to changes in interest rates – as market conditions evolve. They can rotate among sectors when valuations change. They can identify issuers with improving fundamentals and avoid those facing deteriorating credit conditions. They can also access a broader mix of securitized assets, multisector strategies, and nontraditional fixed-income exposures that may not be adequately represented in traditional core benchmarks.

Recent developments within investment-grade corporate credit illustrate the point. Debt issuance tied to artificial intelligence (AI) investment has increased significantly among large technology companies. While these issuers may appear attractive at first glance, growing dispersion in spreads highlights the importance of careful credit analysis and issuer selection. Not all opportunities are created equal.

History suggests active management can be rewarded in fixed income. Our analysis shows that differentiated approaches, measured by tracking error relative to benchmarks, have been increasingly associated with alpha generation in the post-financial-crisis environment.

In other words, the current fixed-income market may offer more opportunities for managers willing and able to look beyond the benchmark.

Looking beyond cash and core bonds

Investors who remain anchored to yesterday’s bond market risk missing what has changed.

Cash is no longer as compelling as it was when the yield curve was deeply inverted. Bond yields remain attractive on both an absolute and real basis. The income advantage traditionally associated with equities has narrowed considerably. And a broader opportunity set is creating new ways for active managers to add value.

For advisors, the opportunity is to reframe how clients think about fixed income. Rather than viewing bonds solely as a defensive allocation, investors may want to consider the asset class as a source of potentially enhanced income, diversification, and portfolio flexibility. In a market where many investors remain positioned for conditions that no longer exist, revisiting fixed income may be less about returning to bonds and more about recognizing how much the asset class has evolved.

All investing involves risk, including the risk of loss. Investment risk exists with equity, fixed-income, and alternative investments. There is no assurance that any investment will meet its performance objectives or that losses will be avoided.

Fixed-income securities may carry one or more of the following risks: credit, interest rate (as interest rates rise, bond prices usually fall), inflation and liquidity.

Mortgage-related and asset-backed securities are subject to the risks of the mortgages and assets underlying the securities. Other related risks include prepayment risk, which is the risk that the securities may be prepaid, potentially resulting in the reinvestment of the prepaid amounts into securities with lower yields. Below-investment-grade fixed-income securities may be subject to greater risks (including the risk of default) than other fixed-income securities.

Foreign and emerging market securities may be subject to greater political, economic, environmental, credit, currency and information risks. Foreign securities may be subject to higher volatility than US securities due to varying degrees of regulation and limited liquidity. These risks are magnified in emerging markets. Currency exchange rates between the US dollar and foreign currencies may cause the value of the fund's investments to decline.

Inflation-protected securities move with the rate of inflation and carry the risk that in deflationary conditions (when inflation is negative), the value of the bond may decrease.

The Bloomberg U.S. Aggregate Bond Index is a broad-based index that covers the US dollar–denominated, investment-grade, fixed-rate, taxable bond market of SEC-registered securities. The index includes bonds from the Treasury; government-related, corporate, mortgage-backed, and asset-backed securities; and collateralized mortgage-backed securities sectors.
