The Evolution of Private Credit

From the rise of leveraged finance in the 1970s to today's golden age of private credit — tracing the milestones, crises, and structural shifts that built today's $1.7T+ market.

1977
Origins

Drexel and the Rise of High-Yield

Michael Milken at Drexel Burnham Lambert begins underwriting high-yield bonds for non-investment-grade companies, creating the financing infrastructure that would later make leveraged buyouts and modern credit possible.

1989
Crisis

Drexel Collapses, Milken Indicted

Drexel files for bankruptcy and Milken is indicted, ending the first chapter of high-yield. The collapse triggers a wave of distressed opportunity and seeds the next generation of credit firms staffed by Drexel alumni.

1990
Landmark Formation

Apollo Founded

Leon Black, John Hannan, and Marc Rowan leave Drexel to found Apollo. The firm builds the playbook for opportunistic credit and distressed investing that defines the modern era of alternative asset management.

1995
Landmark Formation

Oaktree Founded

Howard Marks and Bruce Karsh leave TCW to found Oaktree Capital. The firm becomes the most-followed voice in distressed and credit investing, and Marks's memos become the closest thing the asset class has to a canonical text.

2002
Regulation

Sarbanes-Oxley & the New Credit Era

Post-Enron reforms reshape corporate disclosure and audit standards, raising the cost of public company status. The structural pressure that begins pushing companies — and capital — toward private markets accelerates.

2007
Cycle Peak

Pre-GFC CLO Issuance Peak

CLO issuance hits record levels as syndicated credit markets reach a cyclical peak. The leveraged finance machine is at full speed — and weeks away from breaking.

2008
Crisis

GFC: Banks Retreat from Middle-Market

The financial crisis forces banks to deleverage and exit middle-market lending. The retreat creates a structural gap that direct lending funds and BDCs spend the next decade filling — the seed of modern private credit.

2009
Structural Shift

BDC Era & Direct Lending Boom Begins

Business Development Companies scale rapidly as banks pull back. Ares, Golub, Owl Rock, and others build the operational infrastructure that turns direct lending into a recognized asset class with institutional flows.

2013
Regulation

Leveraged Lending Guidance

OCC, Fed, and FDIC release guidance restricting bank leveraged lending. Banks pull back further; non-bank lenders absorb the displaced capacity. The regulatory tailwind behind private credit becomes durable.

2017
Milestone

Private Credit AUM Crosses $700B

The asset class crosses $700B in AUM, putting it firmly in institutional territory. Allocators stop treating it as a niche and start building dedicated programs.

2018
Structure

Unitranche Becomes Standard

The unitranche structure — single document, blended pricing, single relationship — becomes the default for sponsor-backed direct lending. The market consolidates around a structure that simplifies execution at the cost of a yield premium.

2020
Cycle Event

COVID & Record Direct Lending Vintage

Public credit markets seize for weeks; private credit fills the gap and locks in a vintage with structurally favorable pricing and terms. The 2020 vintage becomes the defining proof point of direct lending's resilience.

2022
Macro

Higher Rates → Private Credit's Golden Moment

The Fed's rate-hike cycle pushes floating-rate yields into the double digits. Howard Marks's 'Sea Change' memo captures the moment: private credit is no longer competing with low-yield alternatives, and capital floods in.

2023
Structural Shift

SVB Collapse & Another Bank Retreat Wave

The collapse of Silicon Valley Bank, Signature, and First Republic triggers another wave of bank retreat from middle-market lending. The structural backdrop for private credit growth gets reinforced again.

2026
Current

Privatization of Credit & First Cracks

Apollo's framing of the $40T global fixed-income market being privatized reaches the mainstream. At the same time, rising defaults, retail-vehicle scrutiny, and questions about volatility laundering surface — the simultaneous golden age and most-questioned moment in private credit's history.

Looking Ahead

As Apollo's "$40T privatization of credit" thesis reaches the mainstream and the first cracks — rising defaults, retail-vehicle scrutiny, and questions about how returns are measured — surface, private credit enters its most consequential phase. The investors and allocators who understand these shifts will define the next era of how the modern economy is financed.
