Some names sit quietly behind the biggest moves in debt markets. Austin Garrison is one of those names—longtime architect and operator inside J.P. Morgan’s credit engine. Understanding who did what, and when, isn’t just gossip; it’s a shortcut to reading liquidity, risk appetite, and execution quality across bonds, loans, and derivatives. If you care about deals getting done—or about building a career in markets—this story matters.
In May 2025, J.P. Morgan reshuffled leadership in leveraged finance and credit trading as Garrison departed after a two-decade run. The headline wasn’t just a personnel note; it was a window into how the largest U.S. bank keeps its credit machine humming through cycles.

Who Is Austin Garrison?
Roles across credit trading and leveraged finance
Garrison’s remit spanned investment-grade and high-yield credit, leveraged loans, and related derivatives—where the job is to warehouse, price, hedge, and distribute risk for issuers and investors. Titles matter less than plumbing: on a busy day, the desk touches everything from a Fortune 100 bond issue to a sponsor-backed LBO loan allocation.
Responsibilities that shaped markets
At scale players, the head of credit is air-traffic control for balance sheet, syndication, and market-making. That means calling risk in choppy tapes, prioritizing clients, and coordinating cash vs. derivatives vs. financing (CLO primary, TRS, repo) so inventory turns and spreads hold.
J.P. Morgan’s Credit Engine — Context You Need
What “credit trading” really covers (IG, HY, loans, CDS, CLOs)
Credit at a universal bank spans:
-
Cash bonds (investment-grade, high-yield)
-
Leveraged loans (institutional and pro-rata)
-
Derivatives like CDS and indices (e.g., CDX)
-
Structured credit such as CLOs (securitizations of loan pools)

Wikipedia
For a broader bond-market orientation, Wikipedia’s core article is handy.
Why scale and balance sheet matter
J.P. Morgan’s market-leading footprint and “fortress balance sheet” make it a natural hub for underwriting and market-making. For context on the firm, see Wikipedia’s profile of JPMorgan Chase.
The 2025 Leadership Transition
Global leveraged finance co-heads named
The bank appointed Brett Nunziata and Rikesh Patel as co-heads of Global Leveraged Finance, aligning sponsor coverage, loan/bond syndicate, and trading under leaders steeped in leveraged products.
Who took over regional credit trading
Jake Pollack, a long-time markets executive who already runs Credit Financing globally, stepped into the North America credit trading seat. He appears frequently in bank and industry content discussing private and public credit.
What stays the same vs. what evolves
-
Same: client focus, distribution heft, and cross-product connectivity.
-
Evolves: deeper integration with private credit partners and financing flows, and sharper capital allocation as regulation shifts.
State of the Market Around the Transition
Corporate bond issuance and trading volumes
U.S. corporate bonds remain a massive market: $11.4T outstanding (1Q25), with $1.31T issuance YTD end-July and $59.5B average daily trading—each up year-over-year. Scale like this is why leadership on a top desk reverberates.
Private credit’s surge and the bank/PCO nexus
Private credit has exploded since 2010, touching roughly $1.7T AUM as of 2023 and on track to keep expanding, with mainstream wealth inflows hitting records in 1H25. Banks, including J.P. Morgan, increasingly partner with private credit managers across financing and distribution.
Leveraged loans, CLOs, and defaults
The leveraged loan and CLO complex has been buoyant, with 2024 a record year for loan activity and 2025 starting strong—though repricings dominated and defaults remain a core risk to monitor. S&P/PitchBook data pointed to a loan default rate near 1.5% through mid-2025, with scenario-based upside/downside.
Case Studies & Real-World Examples
Case Study 1: The 2024–2025 Loan Repricing Wave
With rates stabilizing and technicals tightening, issuers stampeded to reprice and refinance existing loans. January 2025 alone saw staggering volumes, before activity cooled. Syndicate, sales & trading, and financing had to synchronize so investors received paper at fair spreads while issuers locked in savings.
Case Study 2: The High-Yield Issuance Summer
In mid-2025, junk-rated issuance surged on expectations of Fed cuts and strong risk appetite, pushing seasonal records and enabling refinancings. Trading heads shape staffing, inventory risk, and hedges so desks digest supply without blowing out spreads.
How a head of credit shapes execution
On real desks, leadership calibrates:
-
Balance sheet for warehousing;
-
Hedge overlays via CDS/indices;
-
Distribution across real-money, hedge funds, and CLOs;
-
Financing (TRS, repo) so risk turns efficiently.
Significance & Impact
For issuers and sponsors
A strong head of credit reduces execution risk. When a bank underwrites your bridge or launches your HY/loan deal, you want a team that can hold inventory, read the tape, and place risk. That interplay is what Garrison’s organization was built to do.
For investors and liquidity
In a market averaging $59.5B of daily corporate bond trading, depth depends on committed market-makers. Leadership continuity helps maintain two-way liquidity during macro shocks.
For talent and desk culture
Trading floors take on the tone of their leaders. Clear risk frameworks, respect for clients, and smart capital use foster a culture that attracts quant, structuring, and sales talent.
Benefits of J.P. Morgan’s Model
Fortress balance sheet & distribution
The firm’s scale—documented widely—lets it intermediate at size and through volatility. That’s critical when markets shift from risk-off to risk-on in a week. For a general profile, see JPMorgan’s Wikipedia page.
Cross-product connectivity (cash, derivatives, financing)
The modern credit platform links cash bonds/loans with CDS and financing. For a refresher on CDOs/CLOs and credit derivatives, Investopedia’s primers are useful context.
Challenges in Today’s Credit Markets
Liquidity pockets, regulation, and clearing changes
Structural shifts continue: the U.S. moved to T+1 settlement and is implementing SEC Treasury clearing mandates by 2025–2026. While not directly corporate credit, these changes affect funding, margin, and collateral ecosystems that touch every desk. Leaders must plan for new liquidity and operations realities.
Spread cycles and default risk management
Spreads compress during hot issuance windows, then gap on shocks. Scenario planning around defaults and fallen angels remains central, especially with private credit exposures becoming more intertwined with banks’ financing activities. Recent research and outlooks highlight the push-pull between tight spreads and fundamental risk.
Practical Tips — How to Read Leadership Moves in Credit
7 signals to watch in your research
-
Desk mandate: Is the replacement leader more trading- or syndicate-oriented?
-
Capital signals: Does the bank telegraph tighter or looser balance-sheet use?
-
Client coverage: Any shifts toward sponsors vs. corporates?
-
Financing mix: Greater emphasis on CLO primary, TRS, or private credit partnerships?
-
Hedge posture: Watch basis between cash and CDS indices.
-
Distribution breadth: Are allocations broadening beyond the usual buyers?
-
Content cadence: Speeches, podcasts, and thought leadership often flag priorities.
A simple framework for deal watchers
-
Pipeline (mandates, bridges)
-
Placement (orderbooks, price talk vs. prints)

Performance (day-one and week-one)
-
Turnover (inventory velocity and ETF flows)

Future Outlook
Private credit partnerships
Expect deeper bank-PCO collaboration: warehousing, distribution, and co-lending. Recent data show wealth-channel inflows accelerating into evergreen private credit vehicles—another pool of buyers for structured and levered solutions.
Baseline, bull, and bear scenarios for 2025–2027
-
Baseline: Gradual rate cuts, healthy refinancing, and steady HY/loan issuance; defaults range-bound near recent medians.
-
Bull: Faster disinflation, tighter spreads, and record issuance; CLO creation re-accelerates.
-
Bear: Sticky inflation or growth scare; liquidity fractures, and bid-ask gaps widen; banks ration balance sheet.
Why It Matters (Cultural, Social, Economic)
Financing real economy growth
Capital markets fund the majority of corporate financing in the U.S., with debt markets doing most of the heavy lifting—evidence that healthy bond/loan markets are a public good, not just a Wall Street pastime.
Jobs, skills, and inclusion in markets
Large credit platforms employ thousands—sales, trading, quant, tech, ops. Upskilling around data, risk, and market structure expands opportunity and resilience across the labor market.
