What Is a Bank Run? Definition, Examples, and How It Works

A bank run is a financial crisis scenario where a large number of depositors simultaneously withdraw their funds from a bank, typically due to concerns about the bank's solvency or liquidity. This phenomenon can have devastating consequences for the affected bank and, if left unchecked, can potentially trigger a broader financial crisis.

What Is a Bank Run?

A bank run occurs when a significant number of customers simultaneously withdraw their deposits from a bank due to concerns about the bank's financial stability. This sudden surge in withdrawal requests can quickly deplete the bank's cash reserves, making it difficult or impossible for the institution to meet its obligations to depositors.

What Is a Bank Run? Definition, Examples, and How It Works

Causes of Bank Runs

Bank runs can be triggered by various factors, including:

  1. Rumors or speculation: Negative rumors or reports about a bank's financial health can spread quickly, leading to increased anxiety among depositors.
  1. Economic downturns: During periods of economic instability or recession, depositors may become more cautious and seek to withdraw their funds from banks they perceive as vulnerable.
  1. Loss of confidence: If a bank's management or lending practices come under scrutiny or if the bank experiences significant losses, depositors may lose confidence in the institution's ability to safeguard their deposits.
  1. Contagion effect: When one bank experiences a run, it can create a ripple effect, causing depositors at other banks to panic and withdraw their funds as well.

Consequences of Bank Runs

Bank runs can have severe consequences for both the affected bank and the broader financial system:

  1. Liquidity crisis: As depositors withdraw their funds, the bank's cash reserves are quickly depleted, making it difficult to meet its obligations to remaining depositors.
  1. Asset fire sale: To raise additional cash, the bank may be forced to sell off assets at deeply discounted prices, further eroding its financial position.
  1. Insolvency and failure: If the bank cannot meet its obligations or raise sufficient funds, it may be forced into insolvency and ultimately fail, leading to losses for depositors and other creditors.
  1. Contagion effect: The failure of one bank can trigger a loss of confidence in the broader banking system, potentially leading to additional bank runs and systemic financial instability.

How Bank Runs Work

The mechanics of a bank run are relatively straightforward but can have far-reaching consequences:

  1. Withdrawal requests: A bank run typically begins when a significant number of depositors, driven by fear or uncertainty, attempt to withdraw their funds simultaneously.
  1. Cash depletion: As withdrawal requests mount, the bank's cash reserves are rapidly depleted, making it increasingly difficult to meet the demands of depositors.
  1. Asset liquidation: To raise additional cash, the bank may be forced to sell off various assets, such as loans, securities, or other investments. However, during a crisis, these assets often fetch much lower prices than their true value, further exacerbating the bank's financial position.
  1. Liquidity spiral: As the bank struggles to meet withdrawal demands, depositors' concerns may escalate, leading to even more withdrawal requests and a vicious cycle of liquidity depletion.
  1. Insolvency and failure: If the bank cannot raise sufficient funds to meet its obligations, it may become insolvent and ultimately fail, leaving depositors with potentially significant losses, especially if their deposits exceed the insured limit.

 

 

Contagion Effect

One of the most concerning aspects of bank runs is the potential for contagion, where the failure of one bank can trigger a loss of confidence in the broader banking system. This can lead to a cascade of bank runs, as depositors at other institutions become anxious and seek to withdraw their funds as a precautionary measure. If left unchecked, this contagion effect can contribute to a broader financial crisis and severe economic consequences.

Examples of Bank Runs

Throughout history, bank runs have played a significant role in several financial crises, highlighting the vulnerability of the banking system to public confidence and the potential for widespread economic disruption.

The Great Depression

One of the most notable examples of bank runs occurred during the Great Depression of the 1930s. In the wake of the stock market crash of 1929, depositors lost confidence in the banking system, leading to widespread runs on banks across the United States. Between 1930 and 1933, approximately 9,000 banks failed, wiping out billions of dollars in deposits and exacerbating the economic crisis.

Silicon Valley Bank

In March 2023, Silicon Valley Bank (SVB), a prominent lender to technology startups and venture capital firms, experienced a bank run that ultimately led to its collapse. The run was triggered by the bank's announcement of significant losses on its investment portfolio and its plans to raise additional capital. This news sparked concerns among depositors, many of whom were startups and tech companies with substantial sums deposited at SVB. Within days, depositors had withdrawn over $40 billion, forcing regulators to take over the bank and initiate a sale process.

Washington Mutual (WaMu)

In September 2008, during the height of the global financial crisis, Washington Mutual (WaMu), one of the largest savings and loan associations in the United States, fell victim to a bank run. Over the course of two weeks, customers withdrew approximately $16.7 billion from WaMu, representing nearly 9% of the bank's total deposits. This massive outflow of funds, coupled with mounting losses from the subprime mortgage crisis, ultimately led to WaMu's failure and its seizure by the Federal Deposit Insurance Corporation (FDIC).

Wachovia Bank

In the same year as the WaMu crisis, Wachovia Bank, another major U.S. bank, experienced a similar run. Over a two-week period, depositors withdrew over $15 billion from the bank, representing approximately 5% of its total deposits. This run was fueled by concerns about Wachovia's exposure to the housing market and its acquisition of the troubled mortgage lender Golden West Financial Corporation. Ultimately, Wachovia was acquired by Wells Fargo in a government-brokered deal, averting a potential collapse.

Preventing Bank Runs

Given the devastating consequences of bank runs, various measures have been implemented to help prevent and mitigate their impact:

FDIC Insurance

One of the most effective safeguards against bank runs is the Federal Deposit Insurance Corporation (FDIC) insurance. Established in 1933 in response to the bank failures during the Great Depression, the FDIC insures deposits up to $250,000 per depositor, per insured bank. This insurance provides confidence to depositors that their funds are protected, reducing the incentive for panic withdrawals.

Proactive Bank Measures

Banks themselves can take proactive measures to deter bank runs and maintain public confidence:

  1. Temporary closures: In some cases, banks may temporarily close their doors to prevent a run from escalating. This measure can help calm depositors and give the bank time to address underlying issues or secure additional liquidity.
  1. Suspension of withdrawals: Banks may also impose temporary restrictions on withdrawals, allowing only a limited amount of funds to be withdrawn during a specified period. This measure can help preserve the bank's liquidity and prevent a complete depletion of cash reserves.
  1. Communication and transparency: Clear and transparent communication from bank management can help alleviate depositors' concerns and maintain public trust. Banks may issue statements reassuring depositors about the institution's financial stability and addressing any rumors or speculation that may be fueling panic.

Market Confidence

Ultimately, maintaining public confidence in the banking system is crucial for preventing bank runs. This confidence can be fostered through:

  1. Robust regulatory oversight: Strong regulatory frameworks and effective supervision of banks can help ensure their financial stability and adherence to sound banking practices, reducing the likelihood of crises that could trigger runs.
  1. Stable economic conditions: A strong and stable economy, with low unemployment and steady growth, can contribute to public confidence in the financial system, reducing the likelihood of panic-driven withdrawals.
  1. Effective crisis management: When crises do occur, swift and coordinated action by regulatory authorities, central banks, and governments can help restore confidence and prevent isolated incidents from escalating into broader financial instability.
