If you don't recall this hallmark moment in our economic system in 1933 that the separation of commercial bank and investment bank was considered controversial. There was a belief that the separation would lead to a healthier financial system.
In the 1960s the Office of the Comptroller of the Currency issued aggressive interpretations of Glass–Steagall to permit national banks to engage in certain securities activities. Although most of these interpretations were overturned by court decisions, by the late 1970s bank regulators began issuing Glass–Steagall interpretations that were upheld by courts and that permitted banks and their affiliates to engage in an increasing variety and amount of securities activities. Starting in the 1960s banks and non-banks developed financial products that blurred the distinction between banking and securities products, as they increasingly competed with each other.
In 1999 Congress passed the Gramm–Leach–Bliley Act to repeal them. Eight days later, President Bill Clinton signed it into law. Now here is the problem!
When POTUS Clinton signed that measure it repealed part of the Glass–Steagall Act of 1933, removing barriers in the market among banking companies, securities companies and insurance companies that prohibited any one institution from acting as any combination of an investment bank, a commercial bank, and an insurance company.
Which allowed all commercial banks, investment banks, securities firms, and insurance companies to consolidate. Furthermore, it failed to give to the SEC or any other financial regulatory agency the authority to regulate large investment bank holding companies. Fast forward to this playing a major factor in leading to the housing bubble and financial crisis dubbed the financial crisis of 2007–08. Also known as the global financial crisis and the 2008 financial crisis, is considered by many economists to have been the worst financial crisis since the Great Depression of the 1930s.
So, when ask if she will undo what her HUSBAND had helped to cause the worst financial debacle in modern history. Hillary Clinton said "NO"!
