Economists, investors, and historians alike have long been intrigued by the unpredictable nature of financial markets. Market volatility is hardly a modern phenomenon––it has been a part of the economic landscape for centuries. By looking to past financial crises, we can learn valuable lessons. This article delves into historical financial crises and what we can learn from them.

The Great Depression: A Study in Extreme Market Volatility

The Great Depression (1929-1939) was one of the most devastating economic downturns in history. The stock market crash of 1929 marked the beginning of this era of extreme volatility. Historical accounts suggest that a combination of market speculation, banking failures, and inadequate policy response exacerbated this crisis. This period offers a few key takeaways.

Regulation is Crucial 

The lack of oversight during the 1920s allowed speculative bubbles and risky banking practices to proliferate. This resulted in the stock market crash of 1929. In response, the US government implemented regulations like the Glass-Steagall Act to separate commercial and investment banking, aiming to prevent conflicts of interest and reduce systemic risks. 

The Necessity of Proactive Central Banking Policies

The Federal Reserve’s role evolved significantly during the Great Depression. The crisis revealed the importance of solid central banking policies, leading to a more interventionist approach to managing the economy. The Fed learned to use tools like interest rate adjustments and open market operations to stabilize financial markets, control inflation, and promote employment.

Diversification Matters in Market Volatility

Building a diversified portfolio is crucial. Coming out of the Great Depression, economists had to face the reality that concentrating investments in a single asset class led to disaster. Thus, diversification became a fundamental principle in investment strategy, proving that you should never put all your eggs in one basket. 

The Role of Technology in the 1987 Stock Market Crash

Also known as “Black Monday,” the 1987 stock market crash was a sudden and severe event, with the Dow Jones Industrial Average dropping by 22.6% in a single day. This period of market volatility was influenced by automated trading systems, which triggered massive sell-offs at an unprecedented speed. 

Technology’s Double-Edged Sword

One of the most painful lessons to come out of this crisis was the realization that, while advancements in technology lead to greater efficiency, they can also amplify market movements. This, in turn, can cause market volatility. 

The Importance of Circuit Breakers 

Circuit breakers are mechanisms that temporarily halt trading to prevent panic-induced market freefalls, and they really came into the spotlight after the 1987 crash. On October 19, 1987, the Dow Jones Industrial Average plummeted by 22% in a single day, largely due to a lack of safeguards to slow trading.

This rapid decline led to a cascading effect where panic selling intensified, exacerbating the market drop. In response, regulatory bodies introduced circuit breakers to pause trading during extreme market volatility, allowing time for information to disseminate and for market participants to make more rational decisions.

Behavioral Economics’ Impact on Market Volatility and Dynamics

The crash also highlighted the powerful role of behavioral economics in market dynamics. The sharp decline wasn’t just driven by economic fundamentals, but also by investors’ psychology. Essentially, fear and herd behavior led to a self-reinforcing cycle of panic selling. This event underscored that markets are not always rational and that investor behavior can significantly impact market outcomes. 

The 2008 Financial Crisis and the Perils of Over-Leverage

The 2008 financial crisis, triggered by the collapse of the housing bubble in the United States, had far-reaching global repercussions. The excessive use of leverage and risky financial instruments like mortgage-backed securities and credit default swaps was pivotal in the economic meltdown. Here are a few things that came about as a result of the crisis. 

The Need For Risk Management

Leading up to the crisis, many banks and financial firms engaged in highly leveraged and risky practices. At the time, these instruments were poorly understood and inadequately managed, leading to catastrophic losses when the housing market collapsed. It highlighted that effective risk management is vital to preventing large-scale financial failures.

Transparency in Financial Products

The widespread issuance of opaque, complex financial products like collateralized debt obligations (CDOs) concealed the true risk from investors and regulators. Many investors, including institutions, were unaware of the actual level of risk they were exposed to, causing widespread panic when these products failed. 

This lack of transparency contributed significantly to the crisis, demonstrating the need for clear, accurate, and comprehensive disclosure of the risks associated with financial products. 

Regulatory Reforms

In response to the crisis, the government introduced the Dodd-Frank Act in 2010, hoping to reduce systemic risk and prevent further crises of that nature. The Act brought sweeping regulatory reforms, including stricter oversight of financial institutions and the creation of the Consumer Financial Protection Bureau (CFPB).

Applying Historical Market Volatility Lessons to Modern Day

It’s easy to dismiss past crises as mistakes we’ve moved on from, but by continually studying these events, we can learn to read the market and avoid financial ruin. Applying these lessons can also help you make better decisions regarding your own finances, which is ultimately the first step in building a lasting foundation for success.
