Start Chapter 1Frequently Asked Questions
What is private credit?
Private credit refers to non-bank lending provided by institutional investors such as asset managers, insurance companies, and pension funds. It includes direct lending, mezzanine debt, distressed debt, and specialty finance.
How big is the private credit market in 2026?
Private credit assets under management reached approximately $1.5 trillion in 2025, rapidly converging with the US syndicated loan market which stood at $1.78 trillion in H1 2025.
What is Basel 3.1?
Basel 3.1 (also known as Basel III Endgame) is the final set of international banking regulations increasing capital requirements for large banks, particularly for lending activities, making bank lending more expensive and constrained.
What is litigation finance?
Litigation finance is the provision of capital to claimants or law firms in exchange for a share of any recovery. It is increasingly being packaged inside private credit and special situations funds.

Chapter 1 FAQs
How do private credit and bank lending compare in market size in 2026?
The traditional bank lending market and private credit are rapidly converging:
- US syndicated loans (H1 2025): $1.78 trillion
- Private credit AUM (2025): $1.5 trillion
- Growth trend: Private credit has grown at 15-20% annually, while bank lending has remained relatively flat due to capital constraints.
Morgan Stanley's 2026 outlook projects that a refinancing wave combined with new M&A activity will outpace supply, keeping yields elevated in a "higher for longer" interest rate environment.
Why do private equity sponsors choose private credit over banks?
Private equity sponsors increasingly prefer private credit for several reasons:
Advantages of private credit:
- Speed: Private credit funds can commit in 2-4 weeks versus 6-8 weeks for bank syndication.
- Certainty: No market flex risk; committed capital is actually committed.
- Flexibility: Custom covenants, PIK features, and tailored structures not available in bank loans.
- Relationship: Direct lender relationships without syndicate committee approvals.
Disadvantages:
- Higher cost: Typically 300-500 basis points above bank pricing.
- Smaller checks: Individual funds may have lower capacity than bank syndicates.
- Less liquidity: No secondary market for private credit positions.
When banks still win: Banks remain competitive on rate and existing relationship leverage. For investment-grade and large-cap borrowers, bank pricing is still significantly cheaper.
What are the key deal structure trends in private credit?
2025-2026 has seen significant evolution in private credit deal structures:
Unitranche size increase: Average unitranche facility size has jumped 45%, with deals exceeding $1 billion becoming common.
Super-priority revolvers: First-out tranches with priority over the unitranche debt, providing liquidity facilities.
First-out / Last-out stacks: Senior portion (first-out) with lower pricing and priority, junior portion (last-out) with higher pricing.
Holdco PIK (Payment-in-Kind): Interest that accrues rather than being paid in cash, preserving liquidity for portfolio companies.
Mini Case Study: The Direct Lending Advantage
Scenario: A mid-market software company needs $200 million for an add-on acquisition. Bank syndication would take 8 weeks with market flex risk.
Private credit solution: A direct lender consortium commits $200 million in 3 weeks with a unitranche structure at SOFR+700. No flex, no syndication risk. The borrower pays a premium for certainty and speed.
Result: The acquisition closes on time, the borrower achieves synergies, and the lender earns premium yield with strong covenants.
Chapter 1 Practice Questions
Practice Question 1: What are the three key advantages of private credit over bank lending?

Chapter 2 — Basel 3.1 Capital Rules: The Regulatory Push Out of Banks
Estimated Reading Time: 25 minutes
Chapter 2 FAQs
What is the status of Basel 3.1 in the United States as of 2026?
The US Basel III Endgame implementation has been significantly recalibrated:
- Original proposal (2023): Would have increased capital requirements by approximately 20% for large banks.
- Fed's "Basel III Endgame redo" (early 2026): Explicitly aimed at rightsizing and reducing capital hikes for large banks.
- Expected outcome: More moderate increases, potentially 5-10% rather than 20%.
- Timeline: Final rule expected in 2026, with phase-in periods through 2028-2030.
Impact on lending: Even with reduced capital hikes, uncertainty continues to keep bank balance sheets disciplined, leaving mid-market risk increasingly to non-bank lenders.
What is the UK's approach to Basel 3.1 implementation?
The Prudential Regulation Authority (PRA) has taken a deliberate, wait-and-see approach:
- Delay announced: Full Basel 3.1 implementation pushed to January 1, 2027.
- Reason for delay: Waiting for US clarity to ensure competitive parity.
- Phase-in period: Extended to 2030, giving banks time to adjust.
- Key modifications: Reduced output floor impact compared to original proposals.
UK bank response: Major UK banks have maintained lending appetite, but remain cautious on risk-weighted asset growth.
How is the European Union handling Basel 3.1 implementation?
The EU has taken a pragmatic, competitiveness-focused approach:
- Temporary multiplier: Implemented to neutralize trading-book capital impact from 2025.
- Competitiveness debate: Ongoing discussions about whether EU banks are at a disadvantage to US and UK competitors.
- CRR III implementation: EU's Capital Requirements Regulation III incorporates Basel 3.1 with some modifications.
- Timeline: Phased implementation from 2025 through 2030.
Net effect: Global softening of capital requirements, but continued regulatory uncertainty keeps bank balance sheets disciplined across all three jurisdictions.
How does regulatory arbitrage drive the shift to private credit?
Regulatory arbitrage refers to the practice of moving lending activity from highly regulated banks to less regulated non-bank lenders.
How it works:
- Banks face capital charges of 10-20% for corporate loans under Basel 3.1.
- Private credit funds face no such capital charges.
- Banks can originate loans and sell them to private credit funds, freeing up capital.
- Direct lending by private credit funds bypasses bank balance sheets entirely.
The result: Private credit funds can offer competitive yields to investors while providing loans that banks find capital-inefficient to hold.
Mini Case Study: The Capital Relief Trade
Scenario: A large regional bank has a $500 million corporate loan portfolio earning SOFR+400. Under Basel 3.1, holding these loans requires $50 million in additional Tier 1 capital.
The trade: The bank sells the loan portfolio to a private credit fund at a slight discount. The fund holds the loans with no capital charge. The bank redeploys capital to more efficient uses.
Result: Bank capital relief, private credit assets, and continued borrower financing.
Chapter 2 Practice Questions
Practice Question 1: When is the UK's full Basel 3.1 implementation expected?
Answer: January 1, 2027, with phase-in to 2030.
Practice Question 2: What is regulatory arbitrage in the context of private credit?
Answer: Moving lending activity from capital-constrained banks to unconstrained non-bank lenders to avoid capital charges.
Chapter 2 Summary
What are the key takeaways from Chapter 2?
Chapter 2 covered Basel 3.1 capital rules across jurisdictions:
- US: Basel III Endgame redo expected early 2026 with reduced capital hikes.
- UK: Full implementation delayed to January 1, 2027, waiting on US clarity.
- EU: Temporary multiplier to neutralize trading-book impact, competitiveness debates ongoing.
- Net effect: Global softening but continued uncertainty keeps bank balance sheets disciplined.
- Regulatory arbitrage: The fundamental driver of the shift to private credit.

Chapter 3 — Litigation Funding Regulation: Alternative Credit Goes Mainstream
Estimated Reading Time: 25 minutes
Chapter 3 FAQs
What is the current state of litigation funding regulation in the UK?
The UK litigation funding market has experienced significant regulatory developments:
- 2023 Supreme Court ruling (PACCAR): Dealt a major blow to mass-claim funding by classifying some funding agreements as damages-based agreements subject to strict regulation.
- Civil Justice Council (2025-2026): Urges reversal of the PACCAR ruling, proposing light-touch regulation with court approval and capital requirements.
- Proposed framework: Licensing for funders, mandatory disclosure, capital adequacy requirements, and court oversight of funding terms.
- Expected outcome: New legislation or court rules clarifying the status of litigation funding agreements.
How is the European Union approaching litigation finance regulation?
The EU is actively debating harmonized rules for third-party funding:
- European Parliament proposal: Debating licensing requirements for litigation funders operating across EU member states.
- Transparency requirements: Mandatory disclosure of funding terms to courts and counterparties.
- Fee caps: Potential limits on funder returns to prevent exploitation of claimants.
- Capital adequacy: Minimum capital requirements for funders to ensure ability to meet obligations.
Market context: Litigation funding is increasingly framed as a $50 billion by 2035 asset class, with major asset managers packaging funded claims inside private credit and special situations funds.
Why does litigation funding matter for the mid-market?
Litigation funding provides a new source of non-bank liquidity for mid-market companies:
- Affirmative claims: Companies can monetize litigation assets without diluting equity.
- Defense funding: Protection against litigation brought by better-funded opponents.
- Portfolio financing: Law firms can fund multiple cases with institutional capital.
- Special situations: Distressed companies can pursue recovery claims without upfront capital.
Strings attached: Disclosure requirements, funder control rights, and capital adequacy requirements impose new compliance burdens on funders and their portfolio companies.
Mini Case Study: Litigation Finance in Private Credit
Scenario: A private credit fund creates a special purpose vehicle to invest $100 million in a portfolio of commercial litigation claims.
Structure: The fund provides capital to law firms in exchange for a percentage of recoveries. Returns are uncorrelated with public markets.
Result: Diversified returns for fund investors, liquidity for claimants, and a new asset class for private credit managers.
Chapter 3 Practice Questions
Practice Question 1: What did the UK Supreme Court rule in the PACCAR case (2023)?
Answer: The court classified some litigation funding agreements as damages-based agreements subject to strict regulation, creating uncertainty for mass-claim funding.
Practice Question 2: What is the projected size of the litigation finance market by 2035?
Answer: Approximately $50 billion.
Chapter 3 Summary
What are the key takeaways from Chapter 3?
Chapter 3 covered litigation funding regulation:
- UK: Civil Justice Council urges reversal of PACCAR ruling, proposing light-touch regulation with court approval and capital requirements.
- EU: Debating licensing, transparency, fee caps, and capital adequacy for third-party funders.
- Market context: Litigation funding projected to be a $50 billion asset class by 2035.
- Mid-market relevance: New source of non-bank liquidity, but with disclosure and capital-adequacy strings attached.
Keywords: litigation finance, third-party funding, PACCAR, Civil Justice Council, damages-based agreement, special situations, alternative credit
Chapter 4 — The New Mid-Market Architecture: Who Wins When Banks Don't Lend
Estimated Reading Time: 25 minutes
Chapter 4 FAQs
How has the relationship between banks and private credit evolved?
The bank-private credit relationship has shifted from competition to collaboration:
- Early stage (2010-2020): Direct competition for mid-market lending opportunities.
- Current stage (2021-2026): Banks originate loans and sell them to private credit funds (capital relief trades).
- Ecosystem partnerships: Banks provide warehouse facilities to private credit funds.
- Consolidation: Large private credit managers acquiring smaller competitors and building out platform capabilities.
The result: A more integrated ecosystem where banks and private credit funds play complementary roles, with banks focused on capital-efficient products and private credit taking balance sheet-intensive exposures.
What are the key loan terms to watch in 2026?
Several loan terms have become critical negotiation points in private credit transactions:
Covenant packages:
- Maintenance covenants (financial ratio testing) remain standard in private credit.
- Incurrence covenants (only tested upon specific actions) are more common in bank debt.
- Covenant-lite structures are rare in private credit.
PIK toggles: Payment-in-kind options allowing borrowers to pay interest with additional debt rather than cash. Critical for portfolio companies needing liquidity.
Portability: Provisions allowing the loan to be transferred upon a change of control, typically requiring lender consent.
Real-time performance triggers: Modern loan agreements increasingly include automated triggers based on financial covenants, compliance certificates, and key performance indicators.
What are the key risk management considerations in private credit?
As private credit grows, risk management becomes increasingly important:
Concentration risk: Private credit portfolios are heavily concentrated in technology and finance exposures, creating sector-specific vulnerability.
Opaque marks: Private credit assets are not marked to market daily, creating valuation uncertainty and potential for sudden write-downs.
The coming refinancing cycle test: A significant portion of private credit deals were executed at peak valuations. The next refinancing cycle will test underwriting standards.
Mitigation strategies: Diversification across sectors, regular independent valuations, and stress testing of portfolio companies.
Playbook: When to take the bank club vs when to take the direct deal?
Take the bank club when:
- Pricing is the primary consideration (bank debt is cheaper).
- You have an existing relationship with lead banks.
- Loan size exceeds $500 million (private credit capacity may be limited).
- You need ongoing access to capital markets and future refinancing flexibility.
- You can accept longer execution timeline (6-8 weeks).
Take the direct private deal when:
- Speed and certainty are paramount (2-4 weeks to close).
- You need flexible covenant structures or PIK features.
- Loan size is $50-500 million (sweet spot for private credit).
- You are willing to pay a premium for execution certainty.
- You value a direct relationship with decision-makers.
How to price regulatory arbitrage: The spread between bank debt and private credit is effectively the price of regulatory capital relief. Borrowers should model whether the premium for certainty and flexibility justifies the additional cost.
Mini Case Study: The Hybrid Financing Solution
Scenario: A mid-market manufacturing company needs $300 million for a strategic acquisition.
Hybrid solution:
- $200 million senior bank club at SOFR+350 (cheap, but slower execution).
- $100 million private credit unitranche at SOFR+700 (more expensive, but provides speed and certainty).
Result: The company achieves the best of both worlds: cheap capital for the majority of the financing, and a flexible, certain tranche to ensure timely closing.
Chapter 4 Practice Questions
Practice Question 1: When should a borrower choose private credit over bank lending?
Answer: When speed and certainty are paramount, flexible covenants are needed, or loan size is in the $50-500 million range.
Practice Question 2: What is a PIK toggle?
Answer: A payment-in-kind option allowing borrowers to pay interest with additional debt rather than cash, preserving liquidity.
Chapter 4 Summary
What are the key takeaways from Chapter 4?
Chapter 4 covered the new mid-market architecture:
- Evolution: From competition to collaboration, with banks and private credit playing complementary roles.
- Loan terms to watch: Covenant packages, PIK toggles, portability, and real-time performance triggers.
