    4. How does the Federal Deposit Insurance Corporation (FDIC) protect depositors’ funds?

    The U.S. banking system worked fairly well from when the Federal Reserve System was established in 1913 until the stock market crash of 1929 and the Great Depression that followed. Business failures caused by these events resulted in major cash shortages as people rushed to withdraw their money from banks. Many cash-starved banks failed because the Federal Reserve did not, as expected, lend money to them. The government’s efforts to prevent bank failures were ineffective. Over the next two years, 5,000 banks—about 20 percent of the total number—failed.

    President Franklin D. Roosevelt made strengthening the banking system his first priority. After taking office in 1933, Roosevelt declared a bank holiday, closing all banks for a week so he could take corrective action. Congress passed the Banking Act of 1933, which empowered the Federal Reserve System to regulate banks and reform the banking system. The act’s most important provision was the creation of the Federal Deposit Insurance Corporation (FDIC) to insure deposits in commercial banks. The 1933 act also gave the Federal Reserve authority to set reserve requirements, ban interest on demand deposits, regulate the interest rates on time deposits, and prohibit banks from investing in specified types of securities. In 1934 the Federal Savings and Loan Insurance Corporation (FSLIC) was formed to insure deposits at S&Ls. When the FSLIC went bankrupt in the 1980s, the FDIC took over responsibility for administering the fund that insures deposits at thrift institutions.

    Today, the major deposit insurance funds include the following:

    • The Deposit Insurance Fund (DIF): Administered by the FDIC, this fund provides deposit insurance to commercial banks and thrift institutions.
    • The National Credit Union Share Insurance Fund: Administered by the National Credit Union Administration, this fund provides deposit insurance to credit unions.

    Role of the FDIC

    The FDIC is an independent, quasi-public corporation backed by the full faith and credit of the U.S. government. It examines and supervises about 4,000 banks and savings banks, more than half the institutions in the banking system. It insures trillions of dollars of deposits in U.S. banks and thrift institutions against loss if the financial institution fails.14 The FDIC insures all member banks in the Federal Reserve System. The ceiling on insured deposits is $250,000 per account. Each insured bank pays the insurance premiums, which are a fixed percentage of the bank’s domestic deposits. In 1993, the FDIC switched from a flat rate for deposit insurance to a risk-based premium system because of the large number of bank and thrift failures during the 1980s and early 1990s. Some experts argue that certain banks take too much risk because they view deposit insurance as a safety net for their depositors—a view many believe contributed to earlier bank failures.

    Enforcement by the FDIC

    To ensure that banks operate fairly and profitably, the FDIC sets guidelines for banks and then reviews the financial records and management practices of member banks at least once a year. Bank examiners perform these reviews during unannounced visits, rating banks on their compliance with banking regulations—for example, the Equal Credit Opportunity Act, which states that a bank cannot refuse to lend money to people because of their color, religion, or national origin. Examiners also rate a bank’s overall financial condition, focusing on loan quality, management practices, earnings, liquidity, and whether the bank has enough capital (equity) to safely support its activities.

    When bank examiners conclude that a bank has serious financial problems, the FDIC can take several actions. It can lend money to the bank, recommend that the bank merge with a stronger bank, require the bank to use new management practices or replace its managers, buy loans from the bank, or provide extra equity capital to the bank. The FDIC may even cover all deposits at a troubled bank, including those over $250,000, to restore the public’s confidence in the financial system.

    With the fallout from the financial crisis of 2007–2009 still having an effect on banking and financial markets in this country and abroad, the FDIC works closely with the Federal Reserve to make sure that banks continue to maintain healthy balance sheets by “testing” their solvency on a regular basis. Although the future of Dodd-Frank regulations is open to speculation in 2017, the consequences of thinking that banks and other financial institutions were “too big to fail” has had a positive impact on banking and financial transactions with the hope that such a financial crisis can be avoided in the future.
