How do thrift institutions and credit unions serve savers and borrowers?

"Thrift Institutions A thrift institution is a depository institution formed specifically to encourage household saving and to make home mortgage loans. Thrift institutions include savings and loan associations (S&Ls) and savings banks. S&Ls keep large percentages of their assets in home mortgages. Compared with S&Ls, savings banks focus less on mortgage loans and more on stock and bond investments. Thrifts are declining in number. At their peak in the late 1960s, there were more than 4,800. But a combination of factors, including sharp increases in interest rates in the late 1970s and increased loan defaults during the recession of the early 1980s, has reduced their ranks significantly. By year-end 2016, due mostly to acquisitions by or conversions to commercial banks or other savings banks, the number of thrifts had fallen to fewer than 800. 11 Credit Unions A credit union is a not-for-profit, member-owned financial cooperative. Credit union members typically have something in common: they may, for example, work for the same employer, belong to the same union or professional group, or attend the same church or school. The credit union pools their assets, or savings, in order to make loans and offer other services to members. The not-for-profit status of credit unions makes them tax-exempt, so they can pay good interest rates on deposits and offer loans at favorable interest rates. Like banks, credit unions can have either a state or federal charter. The approximately 5,700 credit unions in the United States have more than 108 million members and over $1.34 trillion in assets. The five largest credit unions in the United States are shown in Table 15.5. Although the U.S. credit union system remained strong during the 2007–2009 financial crisis, consumer-owned credit unions in several regions weakened as a result of home foreclosures, business failures, and unemployment rates. Today, the credit union system continues to demonstrate its resilience as the economy continues to rebound. 12 Services Offered Commercial banks, thrift institutions, and credit unions offer a wide range of financial servic"
