CLO Default Rates: Historical Analysis 1994-2025
Last reviewed on May 10, 2026.
Understanding default rates is foundational to evaluating CLO risk. While CLO tranches have never experienced an AAA default, the underlying leveraged loan portfolios do experience periodic defaults—typically 1-10% annually depending on the credit cycle. This page provides comprehensive default rate data and analysis of how defaults flow through the CLO structure.
Key Concepts: Defaults vs. Losses
Critical Distinction
Default ≠ Total Loss. When a leveraged loan defaults, lenders typically recover 70-80 cents on the dollar through bankruptcy proceedings or asset sales. A 3% default rate with 75% recovery = 0.75% net loss rate to the CLO portfolio.
The Loss Calculation
Net Loss Rate = Default Rate × (1 - Recovery Rate)
Example:
- Portfolio: $500M in loans
- Annual defaults: 3% = $15M
- Recovery rate: 75% = $11.25M recovered
- Net loss: $15M - $11.25M = $3.75M (0.75% of portfolio)
This 0.75% loss is absorbed first by equity (8-12% of capital structure), then BB (4-6%), then BBB (5-7%), and so on. AAA (60-65% of structure) has 35-40% subordination protecting it, meaning losses would need to exceed 35-40% of the portfolio before AAA is impaired—a scenario that has never occurred.
Leveraged Loan Default Rates by Year
| Year | Default Rate | Recovery Rate | Net Loss Rate | Macro Context |
|---|---|---|---|---|
| 2000 | 3.2% | 72% | 0.90% | Dotcom bubble peak |
| 2001 | 5.7% | 68% | 1.82% | Dotcom crash; telecom stress |
| 2002 | 6.4% | 65% | 2.24% | Post-9/11 recession |
| 2003 | 4.1% | 70% | 1.23% | Recovery begins |
| 2004-2006 | 1.2-1.8% | 75-78% | 0.30-0.45% | Benign credit environment |
| 2007 | 1.1% | 78% | 0.24% | Credit bubble peak |
| 2008 | 3.4% | 65% | 1.19% | Financial crisis begins |
| 2009 | 9.8% | 58% | 4.12% | Peak of Global Financial Crisis |
| 2010 | 3.5% | 70% | 1.05% | Recovery phase |
| 2011-2014 | 1.8-2.5% | 72-76% | 0.48-0.70% | Post-crisis normalization |
| 2015 | 2.2% | 68% | 0.70% | Energy sector stress begins |
| 2016 | 3.8% | 62% | 1.44% | Energy/commodity defaults peak |
| 2017-2019 | 1.5-1.9% | 74-76% | 0.38-0.49% | Late-cycle benign environment |
| 2020 | 3.2% | 68% | 1.02% | COVID-19 pandemic (rapid recovery) |
| 2021-2023 | 0.8-1.3% | 76-78% | 0.19-0.31% | Post-COVID recovery; benign defaults |
| 2024 | 1.5% | 75% | 0.38% | Higher rates; resilient economy |

Key Observations
- Long-term average: 3.2% annual default rate (1994-2024)
- Range: 0.8% (2021 low) to 9.8% (2009 peak)
- Recovery rates: Consistently 60-80%, averaging 72% over full cycle
- Net losses: Typically 0.5-1.5% in normal years; 2-4% in severe recessions
Recovery Rates: Why Senior Secured Matters
CLOs hold senior secured loans—the first lien on a company's assets. This seniority drives high recovery rates even when companies fail.
Recovery Rates by Loan Type
| Loan/Bond Type | Average Recovery Rate | Range |
|---|---|---|
| 1st Lien Senior Secured Loans (CLO collateral) | 70-80% | 55-90% |
| 2nd Lien Loans | 30-40% | 10-60% |
| Senior Unsecured Bonds | 40-50% | 20-70% |
| Subordinated Bonds | 20-30% | 5-50% |
| Subprime Mortgages (2008 crisis) | 20-40% | 10-50% |
Why 1st lien loans recover more:
- Collateral: Secured by all company assets (equipment, inventory, receivables, IP)
- Priority: Paid first in bankruptcy, ahead of unsecured creditors and equity
- Covenants: Maintenance covenants trigger default before company runs out of cash
- Enterprise value: Loan balance typically 4-6x EBITDA; company's going-concern value >> loan amount
Default Rates vs. CLO Tranche Impairment
The table below shows what default rates would be required to impair each CLO tranche, assuming 75% recovery rates:
| Tranche | Subordination | Default Rate Required for Impairment | Historical Precedent |
|---|---|---|---|
| AAA | 35-40% | 140-160% cumulative defaults (35-40% net losses) | Never occurred |
| AA | 28-35% | 112-140% cumulative defaults | Never occurred |
| A | 21-28% | 84-112% cumulative defaults | Extremely rare |
| BBB | 14-21% | 56-84% cumulative defaults | Rare; 2007 vintages experienced stress |
| BB | 8-14% | 32-56% cumulative defaults | Some 2007-2008 vintages impaired |
| Equity | 0% | Any net losses reduce equity returns | All vintages experience some impact |
Note: "Cumulative defaults" refers to total defaults over the 10-12 year life of the CLO, not annual. A 140% cumulative default means $140 defaults per $100 of original portfolio (due to reinvestment, portfolios turn over).
2009 Case Study: Worst-Case Scenario
Even during the 2009 peak (9.8% annual default rate, the worst year on record):
- Cumulative defaults (2007-2010 cohort): ~18-22% of original portfolio
- Net losses (after recoveries): ~5-6% of portfolio
- AAA impairment: Zero. The 35-40% subordination cushion absorbed all losses.
- AA/A impairment: Minimal. A few 2007 A-rated tranches were downgraded but experienced no principal losses.
- BBB/BB impact: Many experienced payment deferrals (interest diverted to AAA); some BB tranches had principal write-downs.
- Equity impact: 2006-2008 vintages saw 30-60% capital losses.
Default Rates by Industry Sector
CLO portfolios are diversified across 30+ industries. Some sectors default more frequently than others:
| Industry Sector | Avg. Default Rate (2000-2024) | Typical CLO Exposure Limit |
|---|---|---|
| Retail (non-grocery) | 5.8% | 8-10% |
| Energy (exploration & production) | 5.2% | 8-10% |
| Telecommunications | 4.9% | 8-10% |
| Media & Entertainment | 4.1% | 10-12% |
| Healthcare Services | 3.2% | 12-15% |
| Business Services | 2.9% | 12-15% |
| Technology (software) | 2.5% | 12-15% |
| Food & Beverage | 2.1% | 10-12% |
| Chemicals | 1.8% | 8-10% |
| Aerospace & Defense | 1.2% | 6-8% |
Diversification requirements: CLO indentures typically limit single-industry exposure to 10-15% to prevent concentration risk. This ensures no single sector default wave can devastate the portfolio.
Default Rates: CLO Portfolios vs. Broad Market
A critical question: Do CLO managers select better credits, leading to lower defaults than the broad loan market?
CLO Portfolio Defaults vs. Market (2010-2024)
| Year | Broad Loan Market Default Rate | Avg. CLO Portfolio Default Rate | Manager Value-Add |
|---|---|---|---|
| 2010-2014 | 2.1% | 1.8% | -30 bps |
| 2015-2016 | 3.0% | 2.5% | -50 bps |
| 2017-2019 | 1.7% | 1.4% | -30 bps |
| 2020 | 3.2% | 2.8% | -40 bps |
| 2021-2024 | 1.1% | 0.9% | -20 bps |
Key insight: CLO portfolios consistently default 20-50 bps less than the broad market, suggesting manager credit selection adds value. However, this advantage varies by manager tier:
- Tier 1 managers: 40-60 bps below market
- Tier 2 managers: 20-40 bps below market
- Tier 3 managers: In-line with or slightly above market
Forward-Looking Default Expectations (2025-2026)
As of Q4 2024, consensus default rate forecasts:
| Scenario | 2025 Default Rate | 2026 Default Rate | Probability (Consensus) |
|---|---|---|---|
| Base Case | 2.0-2.5% | 2.5-3.0% | 55% |
| Optimistic (Soft Landing) | 1.5-2.0% | 1.5-2.0% | 25% |
| Pessimistic (Mild Recession) | 3.5-4.5% | 5.0-6.0% | 15% |
| Severe Recession | 5.0-7.0% | 7.0-9.0% | 5% |
Key drivers:
- Interest rates: Higher for longer (5%+ SOFR) pressures borrowers with floating-rate debt
- Maturity wall: $500B+ of leveraged loans mature 2025-2027, requiring refinancing
- Covenant-lite: 85%+ of loans are cov-lite, delaying early warning signals
- Private equity dry powder: $1.5T+ available to support portfolio companies
Defaults vs. Credit Spread Widening
Important distinction for CLO debt investors:
- Actual defaults: Impact equity and mezzanine tranches' cash flows
- Expected defaults (spread widening): Impact all tranches' market pricing
Example (March 2020):
- Analysts projected 8-12% default rates
- AAA CLO spreads widened from 130 bps to 500+ bps
- AAA CLO prices fell from 100 to 85-90
- Actual outcome: Defaults peaked at 3.2%; AAA recovered to par by Q4 2020
Lesson: Mark-to-market losses ≠ credit losses. Investors with long time horizons can often "look through" volatility driven by expected (but unrealized) defaults.
How Defaults Flow Through the Waterfall
When a loan defaults:
- Immediate impact: Loan marked down to recovery value (typically 70-80 cents)
- OC test impact: If enough loans default, OC ratios fall below triggers
- Cash diversion: Interest payments diverted from equity/mezzanine to AAA/AA (deleveraging)
- Principal loss: Once loan is liquidated or restructured, realized loss reduces equity NAV
- Sequential absorption: Equity absorbs 100% of losses until wiped out, then BB, then BBB, etc.
