Where to Start with Roger Lowenstein: A Reading Guide
Where to start with Roger Lowenstein — how to approach When Genius Failed, his definitive account of the rise and collapse of Long-Term Capital Management and what it revealed about the gap between financial models and the real world. A complete reading guide.
By Marcus Webb
Roger Lowenstein is an American financial journalist who spent fifteen years as a reporter and columnist at The Wall Street Journal before writing When Genius Failed (2000). He has since written biographies of Warren Buffett and Benjamin Graham and histories of the 2008 financial crisis, the US pension system, and the founding of the Federal Reserve. When Genius Failed remains his most widely read work — the book that established the collapse of Long-Term Capital Management as the essential case study in the dangers of leverage and model-dependent thinking.
Where to Start: When Genius Failed (2000)
The essential Roger Lowenstein — and the most instructive single narrative in modern finance about what happens when elegant theory meets an inelegant world. When Genius Failed begins with John Meriwether, the bond-trading legend who built the most profitable desk in Salomon Brothers history before a trading scandal forced his departure, and traces his assembly of what was, by any measure, the most intellectually credentialed investment firm ever created. Meriwether hired Myron Scholes and Robert Merton — who shared the 1997 Nobel Prize in Economics for their options pricing work — along with a roster of academics and traders who were by training and reputation among the most sophisticated financial thinkers alive.
The strategy was arbitrage, and it was grounded in genuine insight. The same instrument — or two closely related instruments — should trade at the same price, or at a predictable spread. When prices diverge, they tend to converge. Buy the cheaper, short the more expensive, wait for convergence, collect the spread. The mathematics were sound. The problem was scale: to generate attractive returns from spreads measured in fractions of a percentage point, LTCM had to borrow enormous sums. At its peak, the fund held $125 billion in assets on $4.7 billion of equity — leverage of roughly 25 to 1.
The 1998 crisis is the book’s central drama, and Lowenstein reconstructs it with precision. Russia’s August 1998 default triggered a global flight to safety that the models had not adequately accounted for. In normal markets, correlated assets move somewhat together; in a panic, correlations converge sharply — everything falls at once. LTCM’s positions were designed to profit from the differences between related instruments. When everything fell together, the differences disappeared and every position moved against them simultaneously. In five weeks, the fund lost $4 billion.
The Federal Reserve intervention is the episode that elevated the LTCM collapse from a spectacular private failure to a landmark in financial history. The Fed did not bail out the fund’s partners — they were left to absorb their losses. It convened the major banks and brokered an orderly rescue of LTCM’s portfolio because an uncontrolled liquidation of $125 billion in assets would have moved every market the fund was positioned in, potentially triggering the wider crisis the models had made implausible. The fund was not too big to fail; its portfolio was too large to liquidate quickly.
What When Genius Failed established — and what every subsequent financial crisis has confirmed — is that leverage transforms the risk of being wrong from manageable to catastrophic. The Nobel laureates were right that the prices would eventually converge. They were right about almost everything except the one thing that mattered: how long the world could remain irrational.
Reading Roger Lowenstein
When Genius Failed is Lowenstein’s most widely read book and the natural starting point. Readers who want to continue should look at Buffett: The Making of an American Capitalist (1995), his biography of Warren Buffett written with access to Buffett’s associates, and The End of Wall Street (2010), his account of the 2008 financial crisis as LTCM’s larger sequel.

Frequently Asked Questions
Where should I start with Roger Lowenstein?
When Genius Failed: The Rise and Fall of Long-Term Capital Management (2000) is Lowenstein's essential book — a narrative account of the most spectacular hedge fund collapse in financial history. Long-Term Capital Management was run by Salomon Brothers bond legend John Meriwether and staffed by Nobel Prize-winning economists Myron Scholes and Robert Merton. It returned 40 percent annually for four years using leveraged arbitrage strategies, then lost $4 billion in five weeks in 1998 when Russia defaulted and the global markets entered a panic the models had not accounted for. Lowenstein reconstructs the rise and fall with the clarity and momentum of a thriller while keeping the financial mechanics accessible.
What is When Genius Failed about?
The book is about model risk — what happens when a financial strategy that is correct in theory meets a world that behaves unexpectedly. LTCM's approach was theoretically sound: exploit small pricing differences between related securities, wait for them to converge, collect the spread. The problem was leverage: to generate attractive returns from tiny spreads, the fund had to borrow 25 times its equity. When the 1998 Russia crisis triggered a global flight to safety and correlations broke down, the spreads widened instead of converging, and the leverage amplified every loss. The Federal Reserve coordinated a rescue not to save LTCM's partners but because LTCM's unwinding would have threatened the broader financial system.
Does When Genius Failed require a financial background to understand?
No — Lowenstein explains the arbitrage strategies and the mathematics without requiring technical knowledge. The book is structured as narrative non-fiction, not a financial textbook, and the underlying mechanics (buy the cheap instrument, short the expensive one, wait for convergence, borrow heavily to amplify returns) are introduced clearly enough that the logic of the strategy — and the specific way it failed — is accessible to any reader. Some of the bond arbitrage detail requires more attention than others, but the core story of confidence, leverage, and catastrophic miscalculation reads as readily as any business narrative.
What should I read after When Genius Failed?
After When Genius Failed, Michael Lewis's Liar's Poker covers the Salomon Brothers trading culture from which Meriwether and LTCM emerged — essential background that enriches the LTCM story considerably. Peter Bernstein's Against the Gods covers the history of risk and probability with comparable intellectual depth. For the 2008 financial crisis as LTCM's larger sequel, Michael Lewis's The Big Short and Andrew Ross Sorkin's Too Big to Fail are the natural companions.
