William Cohan is a name that often comes up in conversations about Wall Street, finance, and the inner workings of corporate America. As a former investment banker turned investigative journalist, Cohan brings a rare perspective to financial writing—one that blends firsthand experience with sharp storytelling.
If you’re looking to learn about money not just from a theoretical point of view, but from someone who’s actually been in the boardrooms and trading floors, Cohan’s books are a great place to start.
A Career on Wall Street
Before becoming a bestselling author, William Cohan spent 17 years working on Wall Street. He held positions at some of the biggest names in finance, including Lazard Frères, Merrill Lynch, and JPMorgan Chase. This experience gave him an insider’s view of the financial industry, and he uses that insight to dig deep into the motivations and actions of powerful business leaders.
Cohan is not just reporting on the world of finance—he’s been a part of it. That perspective adds credibility and depth to his writing, making his work stand out among other business books.
Notable Books by William Cohan
If you’re on your financial learning journey and enjoy reading books on money, you might want to check out Cohan’s work. His books go beyond surface-level advice. They dive into the human psychology behind money decisions, leadership, and risk.
Here are a few of his most popular titles:
The Last Tycoons: The Secret History of Lazard Frères & Co.
This book takes readers inside one of the most secretive investment banks in the world. It won the 2007 Financial Times and Goldman Sachs Business Book of the Year Award and is a great read for anyone curious about the power structures in finance.
House of Cards: A Tale of Hubris and Wretched Excess on Wall Street
This detailed account of the collapse of Bear Stearns offers valuable lessons about greed, risk-taking, and the importance of understanding how the financial system really works. For those interested in financial history and crisis management, this book is essential.
Money and Power: How Goldman Sachs Came to Rule the World
This book explores the rise of Goldman Sachs and how it became one of the most influential firms in the world. It’s a deep dive into corporate culture, ambition, and the psychological forces driving major financial institutions.
Why His Work Matters
Understanding how money works isn’t just about knowing how to budget or finding the best high-yield savings account. It’s also about understanding the larger financial system—how decisions on Wall Street can affect everyday people.
Cohan’s books help bridge the gap between the personal finance world and the high-stakes world of investment banking. They’re especially helpful for readers who want to go beyond basic budgeting apps and dig into how major economic events unfold behind the scenes.
By reading writers like Cohan, you’re not just learning about money—you’re learning how power and influence operate in the financial world. That kind of knowledge can shape the way you think about investing, saving, and long-term financial planning.
Who Should Read William Cohan?
If you’re someone who’s already tracking your spending, investing in the S&P 500, or thinking about buying a home instead of renting, Cohan’s books offer a higher-level view of how financial systems impact personal finance. They won’t tell you how to create a monthly budget, but they will show you how billion-dollar decisions get made—and how those decisions can affect your 401(k), your savings account, or even your job.
His books are particularly valuable for those who want to become more informed investors or who are considering working with a financial advisor. Knowing the history and psychology behind financial institutions can help you ask better questions and make smarter decisions.
The Bear Stearns Fire Sale, Worked Out
The signature story in Cohan’s House of Cards is the death of Bear Stearns, and the numbers tell it better than any narrative. In January 2007, Bear’s stock traded above $170 a share. On March 16, 2008, JPMorgan Chase agreed to buy the entire firm for $2 a share, about $236 million total. Shareholders revolted, so the price was recut to $10 a share a week later. Even at $10, investors had lost 94 percent from the 2007 peak.
The engine of the collapse was leverage. At the end, Bear was levered about 34 to 1, which means a decline of barely 3 percent in the value of its assets was enough to wipe out its entire equity base. That is the math Cohan keeps returning to: Wall Street’s disasters are not mysteries. They are arithmetic with borrowed money.
What a Top M&A Fee Looks Like
Cohan spent six years at Lazard Freres, a pure advisory shop, and The Last Tycoons reads like a front-row seat at the most lucrative toll booth in business. Here is the fee math that makes those partnerships so rich. On a $10 billion acquisition, an advisory fee of roughly 1 percent means $100 million in revenue for a handful of bankers and their team. Even at half that rate, $50 million, the fee dwarfs the salaries of everyone who will ever work on the deal.
This is why the book’s partners obsess over credit for deals the way athletes obsess over trophies. The economics are simple: enormous, lumpy paydays attached to transactions most people will never hear about. Understanding that math is the fastest way to understand why investment bankers behave the way Cohan describes. He later turned the same lens on General Electric in Power Failure (2022), chronicling how a corporate icon fell apart from the inside.
Final Thoughts
William Cohan writes about money in a way that is both accessible and deeply informed. His background in investment banking allows him to tell complex stories with authority, and his books are a solid choice for anyone serious about learning more about finance and the forces that shape our economy.
Whether you’re new to managing money or further along in your journey, reading authors like Cohan can deepen your understanding of how the financial world really works—and why it matters to your own financial goals.
