Debt Capital Markets & The Debt Universe
Unit 4.3 within Module 4: Credit Risk & Debt Markets. This unit maps the landscape of corporate and leveraged debt --- the instruments, the players, and the contractual mechanics that determine who gets paid first when things go wrong.
Why this unit matters
Understanding the debt universe is essential for anyone who has built credit systems (Credimi, Capital One) and wants to see where those loans sit in the broader capital structure. The difference between investment grade and high yield is not just a rating --- it reflects fundamentally different investor bases, covenant structures, and market dynamics.
Learning roadmap
| Topic | Key concepts | Status |
|---|---|---|
| Investment Grade (IG) vs High Yield (HY) | Rating boundaries (BBB-/BB+), spread dynamics, crossover credits, fallen angels | Planned |
| Leveraged loans | Senior secured, term loan A/B, LIBOR/SOFR floors, CLO demand as a driver | Planned |
| Mezzanine debt | Subordinated debt, PIK (payment-in-kind), warrants, unitranche structures | Planned |
| Subordination & seniority | The priority waterfall: secured senior unsecured subordinated equity | Planned |
| Covenants | Maintenance vs incurrence covenants, covenant-lite trends, leverage ratios, interest coverage | Planned |
| Distressed debt | Trading below par, restructuring, DIP financing, Chapter 11, fulcrum security analysis | Planned |
| The leveraged finance ecosystem | Sponsors (PE firms), arrangers (banks), institutional investors (CLOs, funds), rating agencies | Planned |
Core ideas to internalize
The capital structure waterfall
When a firm generates cash or enters distress, claims are paid in strict order of seniority:
Recovery rates vary dramatically by position: senior secured bonds historically recover ~65% in default, while subordinated debt recovers ~30%. This hierarchy is the backbone of tranching in securitization.
Covenants: maintenance vs. incurrence
Maintenance covenants (traditional IG and old-school leveraged loans) require the borrower to continuously satisfy financial tests --- e.g., tested quarterly. Breach triggers a default.
Incurrence covenants (HY bonds, covenant-lite loans) only apply when the borrower takes an action --- e.g., you can only issue new debt if at that moment. This gives borrowers much more operational flexibility and shifts risk to creditors.
The post-2010 “covenant-lite” trend has blurred the line: most leveraged loans today use incurrence-style covenants, reducing early-warning signals for lenders.
Distressed debt and the fulcrum security
In a restructuring, the fulcrum security is the most senior class of debt that will not be repaid in full. It typically converts to equity in the reorganized firm. Distressed debt investors target this security because:
- It trades at a steep discount (e.g., 40 cents on the dollar)
- It gives control in the restructuring process
- Upside comes from the equity conversion if the business recovers
The analysis requires estimating enterprise value and mapping it against the capital structure to find where value “breaks.”
