The three most important functions are credit, deposit, and money management. First, retail banks offer consumers credit to purchase homes, cars, and furniture. These include mortgages, auto loans, and credit cards. The resulting consumer spending drives almost 70% of the U.S. economy. They provide extra liquidity to the economy this way. Credit allows people to spend future earnings now. Second, retail banks provide a safe place for people to deposit their money. Savings accounts, certificates of deposit, and other financial products offer a better rate of return compared to stuffing their money under a mattress. Banks base their interest rates on the fed funds rate and Treasury bond interest rates. These rise and fall over time. The Federal Deposit Insurance Corporation insures most of these deposits. Third, retail banks allow you, the customer, to manage your money with checking accounts and debit cards. You don't have to do all your transactions with dollar bills and coins. All of this can be done online, making banking an added convenience. Types of Retail Banks Most of America's largest banks have retail banking divisions. These include Bank of America, JP Morgan Chase, Wells Fargo, and Citigroup. Retail banking makes up 50% to 75% of these banks' total revenue. There are many smaller community banks as well. They focus on building relationships with the people in their local towns, cities, and regions. They have less than $10 billion in total assets. Credit unions are another type of retail bank. They may restrict services to employees of companies or schools. They operate as nonprofits. They may offer better terms to savers and borrowers because they aren't as focused on profitability as the bigger banks. Savings and loans are retail banks that target mortgages. They've almost disappeared since the savings and loans crisis of the 1980s. Lastly, Sharia banking conforms to Islamic prohibition against interest rates. So borrowers share their profits with the bank instead of paying interest. This policy helped Islamic banks avoid the 2008 financial crisis. They didn't invest in risky derivatives. These banks cannot invest in alcohol, tobacco, and gambling businesses. How Retail Banks Work Retail banks use the depositors' funds to make loans. To make a profit, banks charge higher interest rates on loans than they pay on deposits. This is how they make a profit. The Federal Reserve, the nation's central bank, regulates most retail banks. One of their regulatory powers is to require banks to maintain a percentage of their deposits on an account at the Fed. They must meet the reserve requirement set by the Fed or restrict business growth. At the end of each day, some banks might be a little short of the Fed's reserve requirement. But this usually isn't a problem because banks that have excess reserves will lend them the necessary difference to make up for the shortfall. The amount borrowed is called the "fed funds." The average rate they're lent at is referred to as the "fed funds rate." That rate is tied closely to the "discount rate," which is the rate the Fed charges them if they have to loan them the overnight funds. The discount rate is the only rate the Fed actually sets. The Fed funds rate is a target range that the Fed hopes to influence the banks to maintain. As goes the discount rate, so moves the Fed funds rate, then other overnight and short-term lending rates to bank customers. How They Affect the U.S. Economy and You Retail banks create the supply of money in the economy. As you can imagine, this is a powerful tool for economic expansion. To ensure proper conduct, the Fed controls this as well. It sets the interest rate banks use to lend fed funds to each other. That's called the fed funds rate. That's the most important interest rate in the world. Why? Banks set all other interest rates against it. If the fed funds rate moves higher, so do all other rates. Most retail banks sell their mortgages to large banks in the secondary market. They retain their large deposits. As a result, they were spared from the worst of the 2007 banking crisis. Retail Banking History In the Roaring 20s, banks were unregulated. Many of them invested their depositors' savings in the stock market without telling them. After the 1929 stock market crash, people demanded their money. Banks didn't have enough to honor depositors' withdrawals. That helped cause the Great Depression. In response, President Franklin D. Roosevelt created the FDIC. It guaranteed depositors' savings as part of the New Deal. The Federal Home Loan Bank Act of 1932 created the savings and loans banking system to promote homeownership for the working class. They offered low mortgage rates in return for low interest rates on deposits. They couldn't lend for commercial real estate, business expansion, or education. They didn't even provide checking accounts. In 1933, Congress imposed the Glass-Steagall Act. It prohibited retail banks from using deposits to fund risky investments. They could only use their depositors' funds for lending. Banks could not operate across state lines. They often could not raise interest rates. Note In the 1970s, stagflation created double-digit inflation. Retail banks' paltry interest rates weren't enough of a reward for people to save. They lost business as customers withdrew deposits. Banks cried out to Congress for deregulation. The 1980 Depository Institutions Deregulation and Monetary Control Act allowed banks to pay interest on certain types of accounts. In 1982, President Ronald Reagan signed the Garn-St. Germain Depository Institutions Act. It removed restrictions on loan-to-value ratios for savings and loan banks. It also allowed these banks to invest in risky real estate ventures. The Fed lowered its reserve requirements. That gave banks more money to lend, but it also increased risk. To compensate depositors, the FDIC raised its limit from $40,000 to $100,000 of savings. Deregulation allowed banks to raise interest rates on deposits and loans. In fact, it overrode state limits on interest rates. Banks no longer had to direct a portion of their funds toward specific industries, such as home mortgages. They could instead use their funds in a wide range of loans, including commercial investments. By 1985, savings and loans assets increased by 56%. But many of their investments were bad. By 1989, many had failed. The resultant S&L crisis cost $160 billion. Large banks began gobbling up small ones. In 1998, Nations Bank bought Bank of America to become the first nationwide bank. The other banks soon followed. That consolidation created the national banking giants in operation today. In 1999, the Gramm-Leach-Bliley Act repealed Glass-Steagall. It allowed banks to invest in even riskier ventures. They promised to restrict themselves to low-risk securities. That would diversify their portfolios and lower risk. But as competition increased, even traditional banks invested in risky derivatives to increase profit and shareholder value. That risk destroyed many banks during the 2008 financial crisis. That changed retail banking again. Losses from derivatives forced many banks out of business. In 2010, President Barack Obama signed the Dodd-Frank Wall Street Reform Act. It prevented banks from using depositor funds for their own investments. They had to sell any hedge funds they owned. It also required banks to verify borrowers' income to make sure they could afford loans. All these extra factors forced banks to cut costs. They closed rural branch banks. They relied more on ATMs and less on tellers. They focused on personal services to high-net-worth clients and began charging more fees to everyone else. Was this page helpful?
