In his insightful work, The Economics of Financial Markets and the 1987 Crash, Paul A. Samuels explores one of the most dramatic financial events of the 20th century—the 1987 stock market crash. The book intricately examines the underlying causes of the crash, how financial markets operate, and the economic implications of such an event. Samuels brings readers into the intricate world of market psychology, regulatory failures, and the mechanisms that led to the sudden collapse. With financial markets more interconnected than ever, understanding the lessons of 1987 remains essential for investors, economists, and policymakers alike.

Samuels begins by setting the stage for the events leading up to October 19, 1987, commonly referred to as “Black Monday.” He provides an analysis of the economic conditions in the early 1980s, emphasizing the shift toward deregulation, rapid growth in computer-driven trading, and the accumulation of excessive leverage in the markets.

“The seeds of the crash were sown in the very euphoria that fueled the bull markets of the early 1980s,” Samuels writes, pointing to how unchecked speculation and over-reliance on new financial instruments such as derivatives set the stage for the disaster.

He discusses the increasing use of program trading—computer algorithms designed to execute large-scale trades at lightning speed, which he argues contributed to the market’s volatility. Samuels gives a concrete example of how these computer-driven trades amplified losses during the initial sell-off, leading to a cascade of margin calls and forced liquidations.

Example 1: In the weeks leading up to the crash, investment banks and institutional traders relied heavily on portfolio insurance strategies, which automatically sold assets as prices declined, pushing the market into a self-reinforcing downward spiral.

The second section delves into the minute-by-minute events of Black Monday. Samuels explains that the Dow Jones Industrial Average (DJIA) plummeted by 22.6% in a single day, marking the largest one-day percentage decline in stock market history.

He provides a gripping narrative of how panic spread across trading floors, with traders unable to keep up with the volume of orders being processed by the early computer systems. “As liquidity evaporated, even the most seasoned market participants found themselves caught in the whirlwind,” Samuels recounts, highlighting how human decision-making was overwhelmed by automated systems that exacerbated the sell-off.

Example 2: One key moment came when the New York Stock Exchange (NYSE) was forced to suspend trading in several stocks, leading to price discrepancies between the NYSE and the futures markets, which worsened the confusion and magnified the market’s instability.

Samuels also discusses how global markets were not immune to the panic. The Tokyo Stock Exchange and London’s FTSE were both hit hard in the aftermath of the U.S. collapse, demonstrating the interconnectedness of global financial markets—a theme that remains relevant in today’s economy.

In the third part of the book, Samuels explores the aftermath of the crash and the immediate responses from central banks and governments. He points out that the Federal Reserve’s intervention was crucial in restoring liquidity to the markets. By lowering interest rates and providing banks with access to emergency funds, the Fed managed to calm the storm, but the damage had already been done.

“The 1987 crash served as a wake-up call for policymakers who had long neglected the structural weaknesses of the financial system,” Samuels argues, referencing the regulatory changes that followed.

One of the major responses to the crash was the introduction of circuit breakers—mechanisms designed to halt trading temporarily in the event of significant market declines. Samuels critically assesses these regulatory responses, questioning whether they merely treated the symptoms rather than addressing the root causes of financial instability.

Example 3: Samuels discusses how the Commodity Futures Trading Commission (CFTC) and the Securities and Exchange Commission (SEC) clashed over the regulation of futures markets versus stock markets. This regulatory fragmentation, according to Samuels, was one of the reasons why the crisis spiraled out of control.

The book’s final section addresses the long-term implications of the 1987 crash for both financial markets and economic theory. Samuels explores the psychological impact of the crash, emphasizing how it changed investor behavior and risk perception. The event led to a reevaluation of market efficiency, with many questioning the assumption that markets are always rational.

“In the aftermath of Black Monday, the myth of the rational market was shattered,” Samuels states, pointing to how the crash exposed vulnerabilities in financial models that failed to account for panic-driven behavior.

He also discusses the role of moral hazard, questioning whether the government’s interventions in the financial markets created perverse incentives for risk-taking. Samuels concludes that while regulatory changes were made, the fundamental issues of leverage, speculation, and complex financial instruments persist in modern financial systems.

In his concluding remarks, Samuels highlights the enduring relevance of the 1987 crash in today’s increasingly complex and interconnected financial markets. While new technologies and regulatory frameworks have been introduced, the underlying dynamics of market psychology, speculation, and leverage continue to pose risks. The book serves as a reminder that financial markets are not infallible and that vigilance and robust regulatory oversight are necessary to prevent future crises.
