Corporate Bond Statistics (2026)

Corporate bonds are one of the largest slices of the US fixed-income universe. The market was about $11.5 trillion outstanding at the end of 2025, up 3.5% year over year and up 0.2% on the quarter (see the table below), according to SIFMA.

That makes corporate debt second only to Treasuries and mortgage-backed securities in size. On the Federal Reserve's broader 'corporate and foreign bonds' definition, which also folds in foreign issuers and asset-backed debt, the total reaches about $16.5 trillion.

Companies sold a record wave of bonds in 2025. US corporate issuance reached roughly $2.216 trillion, up about 12.6% from 2024, with investment grade up about 10% and high yield up about 14% through late November, per SIFMA.

Issuers took advantage of a lower-rate window to fund AI infrastructure, finance acquisitions, and refinance maturing debt, with financials, technology, and communications leading supply. Q1 2026 kept the pace, with about $775 billion issued (up ~15.6% year over year, per a secondary aggregator).

The market splits into two credit tiers. Investment grade covers bonds rated BBB-/Baa3 and above and makes up the large majority of outstanding value (well over $7 trillion). High yield, or 'junk,' covers BB+/Ba1 and below, where higher default risk is paid for with higher coupons (see the table below).

The two behave differently: investment grade is more sensitive to interest rates because of longer duration, while high yield is more sensitive to the economy and credit spreads. In 2026 the yield gap between them was about 190 basis points, historically narrow.

After the 2022-2023 rate rise, corporate bond yields are the highest in more than a decade. The broad ICE BofA US Corporate (investment-grade) index yielded about 5.2% in 2026, spending most of the year between 5.0% and 5.4% yield-to-worst.

High yield paid more: the ICE BofA US High Yield index effective yield was about 6.95% in July 2026, versus a long-run average near 6.5%, and single-B bonds yielded about 7.14% (per FRED / ICE BofA data). A 10-year Treasury near 4.45% anchored the risk-free base.

Within investment grade, yield climbs steadily as ratings fall. In 2026 AAA bonds yielded roughly 4.7%, single-A about 5.1%, and BBB about 5.5%, before jumping to roughly 7% at the high-yield boundary (see the chart and table below).

The AAA-through-BBB figures here are midpoints of an industry aggregator's rating-tier ranges and should be read as approximate; the high-yield and single-B numbers are ICE BofA index yields. The pattern, more yield for more credit risk, is the core trade-off in bond investing.

A credit spread is the extra yield a corporate bond pays over a comparable Treasury, and it is the market's real-time price of default risk. In May 2026 the investment-grade spread (option-adjusted) was about 77 basis points, while high yield sat near 280 to 320 basis points.

Those are tight levels. Spreads compressed from roughly 95 basis points at the end of 2025 to 77 by mid-May 2026, meaning investors were accepting relatively little extra pay for credit risk, a sign of confident, or complacent, markets.

The 77-basis-point investment-grade spread is near the tightest in a generation. It rivals the pre-2008 cycle low of about 80 basis points (February 2007) and sits well below the roughly 130-basis-point 10-year average (see the chart above).

For contrast, spreads blew out to about 370 basis points at the COVID-19 peak in March 2020 and far wider in 2008. Tight spreads mean bonds are 'priced for perfection,' with little cushion if defaults rise or the economy weakens. These comparison points are from a secondary aggregator built on ICE BofA data.

Corporate bonds are largely an institutional asset. On the Fed's Z.1 accounts (2025 Q2), foreign investors held about $4.6 trillion of US corporate and foreign bonds, US life insurers about $3.7 trillion, and mutual funds about $2.4 trillion (see the table below).

Exchange-traded funds have grown into a major channel too, at roughly $1.2 trillion, alongside pension funds and property-casualty insurers. Households directly held only about $244 billion, a reminder that most individuals own corporate bonds through funds, not single issues.

Defaults are the central risk in credit. Investment-grade defaults are rare, running well under 1% even over long horizons, while high-yield defaults are cyclical. Moody's trailing 12-month US high-yield default rate drifted up to about 4.2% in early 2026, from roughly 3.1% a year earlier.

S&P put the speculative-grade default rate at 4.8% as of August 2025, elevated versus the post-2000 average near 2.5-3.4%. Analysts expected defaults to stay in the mid-single digits into 2026 as higher rates pressured weaker borrowers.

Default risk is overwhelmingly a function of rating. On S&P's long-run global study, about 0.82% of AAA issuers default over a 10-year horizon, versus 5.6% for BBB, 30.8% for single-B, and 53.4% for CCC/C (see the chart and table below).

That steep curve is why the investment-grade / high-yield line matters so much: crossing from BBB into BB roughly multiplies long-run default odds several times over. It is also why ratings, despite their flaws, still anchor how the market prices credit.

A default is not a total loss. When a corporate bond defaults, bondholders typically recover a portion of face value through restructuring or liquidation. Moody's long-run data puts senior unsecured recovery near 45% on average, meaning holders lose roughly half (see the table below).

Recoveries are cyclical and move inversely to defaults: senior unsecured bonds recovered about 53.3% in 2007 but only 33.8% in the 2008 downturn. Seniority matters, secured and senior bonds recover more than subordinated debt, which is why capital structure position is central to credit analysis.

Over the long run corporate bonds have delivered more than Treasuries but less than stocks, with high yield closer to equity-like returns. Since 2010 the broad Bloomberg US high-yield index returned roughly 116% cumulatively, and high yield has historically offered equity-like returns with lower volatility.

Returns are strongest coming out of stress: across seven major shocks since 1990, investment-grade corporates returned about 6.7% and high yield about 11.4% in the year after the shock began (per a Bloomberg study). The catch is timing, those gains follow the drawdowns that scare investors out.

A large share of outstanding bonds comes due over the next few years, a so-called maturity wall. Roughly $650 billion of investment-grade debt matures in 2026 and $700 billion or more in each of 2027 and 2028 (secondary estimates), which issuers must refinance at today's higher rates.

For strong investment-grade names this is manageable, but weaker high-yield borrowers face steeper refinancing costs, which is part of why default forecasts crept higher into 2026. Rising-star upgrades outpaced fallen-angel downgrades recently, a sign credit quality was still holding up.

For most individual investors, corporate bonds are a way to earn more than Treasuries and cash while taking measured risk, and yields near 5% (investment grade) to 7% (high yield) in 2026 are the most attractive in over a decade. But tight spreads mean you are not being paid much extra for credit risk right now.

The practical approach is diversification: own corporate bonds through low-cost funds or ETFs rather than single issues, so one default can't sink your position, and match duration to your time horizon. High yield can boost income but behaves more like stocks, so size it accordingly. As always, this is general information, not personalized investment advice.
