Q1 2026 Corporate Bond Market Outlook
Summary
- The Bloomberg (BBG) U.S. Investment Grade (IG) Corporate Bond Index [1] (the Index) generated a total return of 7.77 percent for 2025.
- Spreads touched their tightest level in 20 years. [2] We expect modest spread widening in 2026, and full valuations argue for a defensive stance.
- We see stable credit fundamentals for Industrials in 2026, supported by solid revenue growth and cost discipline, buoying margins, and earnings. [3]
- Rising cap ex and mergers and acquisitions may strain credit metrics if debt funding is used prodigiously. Idiosyncratic events in sub-prime and private credit are risks. [4]
Investment Review and Outlook
IG Credit Looks Poised for Another Year of Attractive Total Returns
As we enter 2026, we are of the view that the next 12 months may be more about total return and less about excess return. In 2025, the corporate market delivered positive excess returns for a third year in a row.5 Favorable coupon income, price appreciation, and modest spread tightening drove the total return on IG corporate credit north of 7.5 percent.6 With potentially range-bound Treasuries and slightly wider spreads, we do not expect a comparable price return in 2026. But we view the income proposition for IG credit as attractive, with a coupon return near 5-percent.
Inflows were nearly half a trillion dollars into taxable bond funds in 2025.7 Foreign investor net corporate bond purchases were one-third of a trillion dollars for the 12 months through October.8 The domestic Insurance sector continues to be a steady source of demand.9 Favorable risk-adjusted performance over the last 12 months may continue to attract steady fund flows into IG corporates. Investor demand will need to remain robust if peak estimates for new issuance come to fruition in 2026. Should markets remain amendable, 2026 gross supply may reach a record at north of $2 trillion.10
We expect stable credit fundamentals in 2026. Agency rating actions have continued with positive bias.11 Credit is supported by solid revenue growth and cost discipline, driving margin improvement and steady debt metrics. However, mergers and acquisitions (M&A) and capital expenditures (cap ex) are each rising notably and may strain credit metrics if debt funding is used prodigiously. Idiosyncratic events in sub-prime and private credit are risks.
Our macro-outlook for 2026 is for moderate real economic growth. Growth has been driven by spending from high income households and a boost in productivity from AI related cap ex. The Breckinridge Investment Committee anticipates one additional rate cut in 2026, with the 10-year Treasury yield expected to trade between 4.0 percent and 4.5 percent. Payroll growth slowed down in the fourth quarter of 2025, and the Federal Reserve’s (Fed’s) view is clear that the labor market has softened sufficiently to warrant additional monetary accommodation to stimulate demand.
We see tactical opportunities in short--to-intermediate-term corporates on reasonable credit curves and breakeven spreads.12 We expect more 30-year issuance, which may present opportunities. Relative value should emerge across capital structures in Banks, Insurers, and Utilities as these sectors may see an increase in hybrid capital supply. Above-average yields, steady investor demand, and stable credit fundamentals are counterbalanced by tight spreads, rising new issue supply, cap ex, and M&A, driving a modest overweight to the corporate sector with a defensive posture.
Valuations: Sector Dispersion and Opportunities
IG corporate bond spreads, as measured by the Index, tightened by two basis points (bps) during the year, ending the fourth quarter at an option-adjusted spread (OAS) of 78bps.13 Spreads are rich, in the 2nd percentile over a 20-year lookback. Compressed valuations argue for a defensive stance entering 2026. The yield-to-worst (YTW) for the Index was 4.81 percent on December 31st. An IG YTW in the 66th percentile, since 2005, may support investor demand via domestic and foreign funds flows.14
Long corporates (-4bps) modestly outperformed intermediate corporates (-2bps) on a spread basis, as credit curves flattened slightly. There was dispersion across industries, with tighter spreads in sectors such as Healthcare (-13bps), Banking (-9bps) and Capital Goods (-8bps), partially offset by wider spreads in Finance (+30bps), Technology (+11bps), and Utilities (+2bps) for the full year.
Quality spreads widened slightly during the year, with the A Index (+64bps) 4bps tighter and the BBB Index (+97bps) unchanged on the year. The spread differential of 33bps is tight relative to recent history with a Z-Score15 of negative 1.5 compared to the average over the last five years.16 The spread/yield conundrum reminds us of prior periods (1995-1997 and 2004-2006), with relatively high risk-free rates and tight spreads that lasted for a few years. This relationship can persist until a financial shock and/or a sharply weakening economy prompts a material drop in the fed funds rate and Treasury yields that correspond with a higher credit risk premium.
Technicals: Supply Rising, Demand Still Deep
Entering 2026, we think bond supply may accelerate on rising cap ex and M&A activity. IG gross bond supply was $321 billion in the fourth quarter, and $1.82 trillion in 2025. On a net basis, after redemptions, issuance was $86 billion and $548 billion, respectively.17
We expect to see more supply in longer-maturity corporate bonds this year, which may present opportunities, particularly for yield-oriented buyers. One investment bank is estimating gross and net issuance of $2.25 trillion and $1.0 trillion in 2026, respectively, which would eclipse the previous gross record of $2.1 trillion in 2020.18
We think fund flows can remain healthy while IG supply may accelerate on rising cap ex and M&A activity. Inflows into taxable bond funds and exchange-traded funds (ETFs) were $156 billion in the fourth quarter and $490 billion in 2025.19 Foreign investor net corporate purchases were $83 billion for the three months and $304 billion for the 12 months through October.20
On the supply side, we expect large issuance from the Technology and Utility sectors to be somewhat counterbalanced by less supply from the Banking sector.
Utilities may also materially increase their borrowing in the corporate bond market in 2026. Utility cap ex grew from $104 billion in 2015 to $208 billion in 2025 and may reach $248 billion in 2029.21 Cap ex will bring a wave of new debt issuance.22
In the fourth quarter, U.S. Bank regulators issued a final rule to modify certain regulatory capital standards including changes to the Supplementary Leverage Ratio (SLR) that will likely reduce holding company long-term debt (LTD) issuance needs.23 These regulatory changes could reduce external LTD requirement by over $150 billion and Total Loss Absorbing Capital (TLAC) needs by nearly $100 billion.24 Higher surplus LTD suggests reduced refinancing and U.S. Bank net supply may be sharply lower, potentially down 40 percent in 2026.25 We view lower supply as a supportive technical for Bank bond spreads.
Fundamentals: Stable, With Pockets to Watch
We see stable credit fundamentals for Industrials in 2026. Non-financial credit metrics were stable in the last quarter and indeed over the past few years.26 Credit is supported by solid revenue growth and cost discipline, which are driving margin improvement and steady debt metrics.
Net leverage was flat for the Index, at about 2.9 times. Sectors with the biggest increase in net leverage on a year-over-year (Y/Y) basis included Basic Industries (+0.5x), and the biggest reduction in net leverage on a Y/Y basis included Communications (-0.3x) and Consumer Non-Cyclical (-0.2x).27
Industrials margins continued their steady march higher and corporate investments in artificial intelligence (AI) may drive additional costs savings and productivity. Forecasts for solid growth in operating earnings suggest a constructive backdrop in credit.28 Agency credit rating actions continued to have a positive bias in 2025 and that may continue.29 Cap ex and M&A are rising and may strain metrics if heavily debt funded.30 Not surprisingly, there is divergence across sectors.
Bank fundamental credit looks stable. Merger activity may be supportive of credit, given equity funding, and M&A among regional banks. Regulatory capital relief may allow for greater loan growth and more profitable lending activities. Idiosyncratic events in sub-prime, private credit, and bank exposure to non-depository financial institutions (NDFI’s) are risks.31 We expect large issuance in the Tech sector to fund data center buildouts. Some deals may present opportunities given how highly rated these credits are. We expect Utilities to maintain current credit ratings driven by rate increases, increased equity funding in the form of common and hybrid issuance, and asset sales.32
