Banking crises can be caused by inadequate governmental oversight, bank runs, positive feedback loops in the market and contagion.

Learning Objectives

Describe some common causes of a banking crisis, Explain a bank run

Key Takeaways

Key Points

• A bank occurs when many people try to withdraw their deposits at the same time. As much of the capital in a bank is tied up in investments, the bank's liquidity will sometimes fail to meet the consumer demand.
• Due to the mass interdependence of economies across the globe, a banking crisis in one nation is likely to dramatically affect other international economies.
• The Great Depression in 1929 resulted from a variety of complex inputs, but the turning point came in the form of a mass stock market crash (Black Tuesday) and subsequent bank runs.
• Irresponsible and unethical leveraging in these assets by the banks, and mass governmental failure to listen to economists predicting this over the past decade, caused the 2008 stock market crash and subsequent depression.
• Irresponsible and unethical leveraging in these assets by the banks, and mass governmental failure to listen to economists predicting this over the past decade, caused the 2008 stock market crash and subsequent depression.

Key Terms

• Bank Run: A large number of customers withdraw their deposits from a financial institution at the same time due to a loss of confidence in the banks.
• leverage: The use of borrowed funds with a contractually determined return to increase the ability of a business to invest and earn an expected higher return, but usually at high risk.

In light of recent market and banking failures, the economic analysis of banking crises both historically and presently is a constant source of interest and speculation. Banking crises are when there are widespread bank runs: an abnormal number depositors try to withdraw their deposits because they don't trust that the bank will have the deposits for withdrawal in the future.

Banking crises are not a new economic phenomenon, and similarly are not the only source of financial crises. Over the course of the past two centuries there have been a surprisingly large number of financial crises, as demonstrated in the attached figure. In understanding banking crises over time, it is useful to identify the causes in context with historic examples of banking collapses.

Financial Crises Globally since 1800: This chart is an interesting take on the relatively consistent frequency in which financial crises occur across the globe. It is interesting to note both the efficacy of |Bretton Woods alongside the increasing risk of financial collapse in modern times.

Causes of Banking Crises

Banks can fail for several different reasons:

• Bank Run: A bank occurs when many people try to withdraw their deposits at the same time. As much of the capital in a bank is tied up in investments, the bank's liquidity will sometimes fail to meet the consumer demand. This can quickly induce panic in the public, driving up withdrawals as everyone tries to get their money back from a system that they are increasingly skeptical of. This leads to a bank panic which can result in a systemic banking crisis, which simply means that all of the free capital in the banking system is withdrawn.
• Stock Market Positive Feedback Loops: One particularly interesting cause of banking disasters is a similar positive feedback loop effect in the stock markets, which was a much more dynamic factor in more recent banking crises (i.e. 2007-2009 sub-prime mortgage disaster). John Maynard Keynes once compared financial markets to a beauty contest, where investors are merely trying to pick what is attractive to other investors. There is a profound truth to this, creating an interdependent and potentially self-fulfilling investment thought process. This can create dramatic rises and falls (bubbles and crashes), which in turn can throw banks with poorly designed leverage into huge losses.
• Regulatory Failure: One of the simplest ways in which bank crises can occur is a lack of governmental oversight. As noted above, banks often leverage themselves to capture gains despite extremely high risks (such as over-dependence on derivatives).
• Contagion: Due to globalization and international interdependence, the failure of one economy can create something of a domino effect. In 2008, when the U.S. economy collapses, the reduced buying power and economic output from that economy dramatically damaged all economies dependent upon it (which includes most of the world). This is called contagion.

The Great Depression highlights how bank runs caused a banking crisis, which ultimately became a global economic crisis. The Great Depression in 1929 resulted from a variety of complex inputs, but the turning point came in the form of a mass stock market crash (Black Tuesday) and subsequent bank runs. As fear began to grip consumers across the United States, people became protective of their assets (including their cash). This caused a large number of people to the banks to withdraw, which in turn motivated others to go to the banks and get their capital out also. Since banks lend out some of their deposits, they did not have enough cash on hand to meet the immediate withdrawal requests (they became illiquid) and therefore went bankrupt. Within a few weeks this resulted in a systemic banking crisis.

1929 Stock Market Crash: As the market falls, investors create a positive feedback loop and self-fulfilling prophecy due to a lack of confidence that drives it down even further.
