Investment-grade credit faces a pivotal moment in 2026. Corporate fundamentals are strong, and index quality is improving, yet spreads are tight, and issuance is expected to increase significantly. Unlike previous cycles, the main challenge is not declining credit quality, but the scale and nature of supply in a market priced toward the rich end of historical valuations. Opportunities are now defined by security selection and avoidance, focusing on areas where strong fundamentals align with manageable supply, resilient demand, and disciplined capital allocation.
Consensus reflects this tension. Most forecasts anticipate investment-grade spreads widening by 20 to 30 basis points in 2026, as markets absorb increased issuance. Gross supply is estimated to be between $1.5 and $1.8 trillion, with net issuance expected to rise sharply to about $600 to $800 billion, roughly 25% to 50% higher than in 2025. The prevailing view is clear: spreads are tight, supply is rising, and technicals are moving away from being so supportive.
This perspective is reasonable but does not capture the full picture.
How the market absorbs new supply is more important than headline forecasts. In 2026, the key questions who is issuing, why capital is being raised, how it is used, and where on the maturity spectrum it is being issued. Supply that supports productive investment, balance-sheet resilience, and sustainable earnings should be distinguished from supply driven by excessive leverage, financial engineering, or non-economic incentives. The market is increasingly differentiating between these uses of funds, resulting in greater dispersion. We expect dispersion to continue to increase in 2026.
Index quality is improving even as issuance accelerates. Large, high-quality issuers, especially in technology, infrastructure, data, and artificial intelligence, now represent a larger share of supply. Technology’s weight in the investment-grade index has risen from about 4% in 2010 to roughly 10% today and could move into the high-teens over time, supported by an estimated $150–$200 billion of issuance in 2026. These issuers generally have higher margins, stronger liquidity, higher ratings, and lower net leverage than the index average. This shift helps explain why spreads have remained resilient despite record issuance.
Demand dynamics remain positive. Although increased supply is a headwind, the market is still under-allocated to fixed-income duration, and largely underweight duration. Liquidity has improved significantly: investment-grade trading volumes reached about 89% of index notional value in 2025, up from 85% in 2024 and 71% in 2023*, with portfolio trading activity rising over 15% year over year. This depth enables markets to absorb supply more smoothly and reduces the risk of disorderly repricing as issuance increases.
Valuations leave little room for complacency. Investment-grade spreads are near historical tights, and spread curves remain flat. While all-in yields remain attractive, tight spreads limit incremental compensation for balance-sheet risk and capital allocation discipline, increasing the cost of indiscriminate exposure. In this environment, success depends less on predicting spread direction and more on avoiding situations where fundamentals are deteriorating, and spreads are vulnerable to significant widening.
Dispersion is now a dominant feature of the market.
Artificial intelligence, in our view, is central to this cycle, reshaping both the composition of supply and the distribution of outcomes. Much of the AI-related issuance is concentrated in longer maturities, increasing duration pressure even as headline spreads remain stable. Over time, performance will depend more on returns on invested capital than on issuance volume. The credit market will reward issuers whose investments generate durable earnings and penalize those whose capital intensity exceeds cash-flow realization.
This dynamic extends beyond technology. M&A activity is another source of dispersion, with issuance tied to strategic transactions expected to rise significantly in 2026. M&A-related supply is projected to increase from roughly $170 billion to approximately $245 billion, representing more than $70 billion of incremental supply year over year (+44%). Some transactions enhance competitive positioning and cash flow stability, while others add leverage when spreads offer little margin for error. In a fully priced market, avoiding risk is as important as participating. We believe that preserving optionality can be as valuable as deploying capital into acquisition-driven supply based on aggressive assumptions.
Consumer-related credits further illustrate how dispersion is developing beneath otherwise stable index conditions. Fundamentals remain broadly supportive, and many consumer-facing issuers continue to report better-than-expected results, though the pace of improvement has slowed. Outside of technology, earnings assumptions increasingly rely on steady growth rather than expansion, leaving less margin for error and reinforcing the importance of disciplined issuer selection.
These tensions are most visible in long-duration investment-grade credit as well. Long-end supply is likely to increase as fewer expected rate cuts; AI-related funding needs, and M&A activity favors longer maturities. Since the most recent bout of volatility, long-duration investment-grade spreads have widened even as the broader index remained stable, steepening the spread curve, though only marginally so far. We believe that opportunity remains, but only where balance-sheet durability and capital discipline are clear over extended horizons.
Rising stars and fallen angels add another layer of complexity. Upgrades continue to offer incremental returns as balance-sheet strengthening proves durable, and earnings visibility improves, with projected rising-star volumes estimated at $15 to $35 billion. At the same time, fallen angels are expected to increase, potentially $70–90 billion, driven by leverage tied to M&A and sector-specific pressures. These transitions create forced flows and technical dislocations, but only disciplined fundamental analysis separates opportunity from value traps.
Collectively, these factors lead to one conclusion: investment-grade credit in 2026 will not be defined by a single outcome or forecast. A modest widening of spreads is a reasonable base case, but the more significant development is the increasing dispersion beneath stable index levels. Success will depend less on predicting direction and more on identifying where supply is constructive, demand is durable, and balance sheets are strengthening. Security selection and avoidance matters.
At Smith Capital Investors, our approach aligns with this reality. We focus on risk-adjusted returns through bottom-up fundamental analysis, dynamic sector rotation, and intentional positioning. Capital preservation is central. In a changing and less forgiving market, discipline determines who succeeds.
Investment-grade credit continues to offer opportunity in 2026, but it must be earned.
