Release Date: December 18, 2025
Hosts: Michael Lewis, Lydia Jean Kot, Sean Pyles, Elizabeth Ayola
Featured Guest: Matt Levine (Bloomberg columnist, former Goldman Sachs investment banker)

Overview

This special episode explores the lasting financial, cultural, and structural consequences of the 2008 financial crisis on Wall Street, using Michael Lewis’s The Big Short as a jumping-off point. Michael Lewis and Matt Levine (Bloomberg columnist, former Goldman Sachs banker) dissect how regulation, risk-taking, and even the labor market have transformed, and delve into the rise of crypto, the status revolution on Wall Street, and whether the system is safer—or just different—15 years later.

Key Discussion Points & Insights

1. Wall Street Then vs. Now: The Shift in Risk ([04:13–13:56])

• Change in Institutional Status

  • Pre-2008, Goldman Sachs, Morgan Stanley, and similar investment banks were the elite places to work, drawing the best talent and undertaking the biggest trades.
  • Post-crisis, regulatory changes (stricter supervision, requirements for more stable funding, curbs on proprietary trading) shifted power and prestige away from traditional banks to hedge funds, private equity, and high-frequency trading firms.
  • Matt Levine:

    “After the financial crisis the power really shifted away from the investment banks for a bunch of reasons, largely regulatory... the prestige locations on Wall Street have shifted to the big hedge funds, the big asset managers, the big high-frequency trading firms.” (10:12)

• Risk Socialization and Regulation

  • The crisis revealed that bank failures could have economy-wide consequences, leading to socialized losses (i.e., government bailouts).
  • Regulators aimed to limit banks’ risk-taking since the public ultimately bore the downside.
  • Matt Levine:

    “The system right now feels less blow up than it was in 2007 because there is less of that short-term financing against like whatever people are up to.” (13:54)

2. New Players, New Risks: The Rise of Alternative Asset Managers ([10:12–15:09])

• Who Takes Risks Now?

  • Roles once exclusive to banks are now performed by private credit funds, hedge funds, and “shadow banks” (less-regulated firms).
  • Michael Lewis:

    “We all decided that these places shouldn’t be doing this thing because the risk gets socialized if they screw it up.” (12:19)

• Potential Dangers of the New Structure

  • Shadow banks aren’t subject to the same oversight, and risk is creeping back into the system through leverage in hedge funds and private credit, sometimes reconnected with traditional banks.
  • Matt Levine:

    “Leverage is creeping back into the system because it has a habit of doing that. Private credit firms do get leverage from banks, so it’s kind of circulating back into the banking system..." (15:09)

3. Bitcoin & Crypto: The Crisis’s Most Radical Legacy ([17:15–22:10])

• Bitcoin as a Reaction

  • The pseudonymous Satoshi Nakamoto created bitcoin, per its white paper, in direct response to the financial crisis’s revealed flaws—the dangers of central intermediaries and socialized risk.
  • Matt Levine:

    “It seems like Satoshi Nakamoto was upset by the leverage in the banking system and by the socialization of losses... and wanted a financial system... that was peer to peer and decentralized and safe.” (17:15)

• Ironies and Cycles

  • Despite this origin, crypto has quickly recreated many features of traditional finance—the use of leverage, opaque intermediaries, and crashes—culminating in events like the collapse of FTX.
  • Michael Lewis:

    “One of the many ironies of crypto is that it seems to be born out of mistrust of institutions… and then it goes and recreates institutions and intermediaries and requires even more trust...” (18:33)

  • Matt Levine:

    "Crypto winter... really beat for beat is like this is what happens when you over lever something... and there’s no regulation and there’s a lot of nontransparency." (19:18)

• Bailouts and Systemic Impact

  • In 2008, banks were bailed out to protect the real economy. In crypto’s crises, there were no bailouts—because, at least for now, the fallout is largely contained within the crypto sector.
  • Matt Levine:

    “There’s no government bailout because it didn’t matter. Like all of crypto could go to zero and nothing outside of crypto would be affected by that.” (21:06)

4. Key Lessons (Learned and Unlearned) from the Crisis ([24:33–29:09])

• Root Cause of Crises: Short-term Funding on Long-term or Risky Assets

  • The most dangerous banking practice is funding long-term or supposedly "safe" assets with short-term, “runnable” debt.
  • Matt Levine:

    “Short term information-insensitive leverage on stuff that you think is safe is the dangerous thing, right?” (24:40)
    “The problem is when you... buy stuff that they think is pretty safe... So we can fund it by borrowing overnight... That is the source of all financial crises.” (24:57)

• Did We Fix It?

  • Regulations now focus on requiring banks to hold more capital and less short-term funding, reducing this vulnerability—at least in traditional banks.
  • However, parallel risks persist and reemerge in new sectors (shadow banks, crypto) that are less stringently regulated.

• Where Does the Next Crisis Hide?

  • Levine sees large, highly-leveraged multi-strategy hedge funds as possible sources of future crises:

    “The big hedge funds are really interesting... they do a lot of the businesses that banks used to do. They’re very levered…” (28:04)

5. The Broader Social Impact: Power Loss and the CFPB ([29:20–30:40])

• Political and Cultural Fallout

  • Public anger and loss of stature for banks post-crisis made regulation politically easier, exemplified by the creation of the Consumer Financial Protection Bureau (CFPB).
  • Matt Levine:

    “The big banks lost status. Now you can go to Congress and say banks should not be able to charge overdraft fees, and everyone’s like, oh yeah, those banks—they suck.” (29:20)

• The CFPB’s Complex Legacy

  • While rooted in consumer protection, much of the CFPB’s work is not directly tied to the specific causes of the 2008 crisis, but arises from a climate more willing to regulate and penalize banks.

6. Narrow Banking, Stablecoins & The Future of Finance ([30:40–34:53])

• Stablecoins as Narrow Banking

  • Stablecoins and money market funds are ways to “de-risk” holdings by parking money in very low-risk assets (like Treasury bills) instead of relying on banks making riskier loans.
  • This trend could threaten the traditional banking model, especially for regional banks dependent on deposits.
  • Matt Levine:

    "Banking has become narrower... Instead of having your money at a bank... you have your money in this thing, a stablecoin that basically invested in treasury bills." (30:40)

• A Bankless World?

  • It’s possible to imagine a future financial system where banks fade in importance—deposits held as stablecoins or directly with the Fed, and loans given by alternative institutions.
  • Matt Levine:

    “I think it’s pretty easy to imagine a world without banks. It’s very hard to imagine the transition... but if it happens... the financial crisis would be the great catalyst for it.” (34:41)

Notable Quotes & Memorable Moments

• Matt Levine on the day Lehman collapsed ([06:30]):

  “I went outside to get coffee and everyone was walking around being completely normal. And I had the thought of, like, what? Do you not understand the world just ended?”

• Michael Lewis reflecting on Wall Street’s esprit de corps ([09:29]):

  “You know who also feels like that? People who work at the IRS... they know everybody hates them, and they think what they’re doing is virtuous, but they know everybody hates them, and it somehow brings them together.”

• Matt Levine on learning from the crisis ([24:56]):

  “Runnable short-term debt is the thing that causes financial crises... Can people take their money out? It’s not the asset side. And so people worry a lot about risky stuff. Risky stuff is fine.”

• Michael Lewis on the endless cycles of finance ([20:27]):

  “One thing you learn is that it’s all the same thing, right? Like a financial crisis is they all look the same.”

Overall Tone

The tone is both candid and analytical, mixing Lewis’s narrative wit with Levine’s technical grasp. The discussion is accessible while delving deep into systemic issues and encouraging listeners to consider both the progress and perils in the decade-plus since the 2008 collapse.

Conclusion

The episode provides a nuanced look at “what’s changed, what hasn’t, and what’s coming” in the post-2008 financial world. It encourages vigilance about systemic risk migration, skepticism about overly simple solutions (crypto included), and awareness that each financial innovation or regulation creates new opportunities—but also new vulnerabilities. The 2008 financial crisis did not end risk, but it redistributed, shape-shifted, and possibly even seeded revolutions in finance still unfolding today.
