Dodd–Frank Wall Street Reform and Consumer Protection Act in the context of "Investment banks"

The Federal Deposit Insurance Corporation (FDIC) is a United States government corporation supplying deposit insurance to depositors in American commercial banks and savings banks. The FDIC was created by the Banking Act of 1933, enacted during the Great Depression to restore trust in the American banking system. More than one-third of banks failed in the years before the FDIC's creation, and bank runs were common. The insurance limit was initially US$2,500 per ownership category, and this has been increased several times over the years. Since the enactment of the Dodd–Frank Wall Street Reform and Consumer Protection Act in 2010, the FDIC insures deposits in member banks up to $250,000 per ownership category. FDIC insurance is backed by the full faith and credit of the government of the United States, and according to the FDIC, "since its start in 1933 no depositor has ever lost a penny of FDIC-insured funds".

Deposits placed with non-bank fintech financial technology companies are not protected by the FDIC against failure of the fintech company. If the company places the money in an FDIC-insured bank account consumers are protected only under some conditions.

Investment banking is an advisory-based financial service for institutional investors, corporations, governments, and similar clients. Traditionally associated with corporate finance, such a bank might assist in raising financial capital by underwriting or acting as the client's agent in the issuance of debt or equity securities. An investment bank may also assist companies involved in mergers and acquisitions (M&A) and provide ancillary services such as market making, trading of derivatives and equity securities, FICC services (fixed income instruments, currencies, and commodities) or research (macroeconomic, credit or equity research). Most investment banks maintain prime brokerage and asset management departments in conjunction with their investment research businesses. As an industry, it is broken up into the Bulge Bracket (upper tier), Middle Market (mid-level businesses), and boutique market (specialized businesses).

Unlike commercial banks and retail banks, investment banks do not take deposits. The revenue model of an investment bank comes mostly from the collection of fees for advising on a transaction, contrary to a commercial or retail bank. From the passage of Glass–Steagall Act in 1933 until its repeal in 1999 by the Gramm–Leach–Bliley Act, the United States maintained a separation between investment banking and commercial banks. Other industrialized countries, including G7 countries, have historically not maintained such a separation. As part of the Dodd–Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd–Frank Act of 2010), the Volcker Rule requires some institutional separation of investment banking services from commercial banking.

The Troubled Asset Relief Program (TARP) is a program of the United States government to purchase toxic assets and equity from financial institutions to strengthen its financial sector that was passed by Congress and signed into law by President George W. Bush. It was a component of the government's measures in 2008 to address the subprime mortgage crisis.

The TARP originally authorized expenditures of $700 billion. The Emergency Economic Stabilization Act of 2008 created the TARP. The Dodd–Frank Wall Street Reform and Consumer Protection Act, signed into law in 2010, reduced the amount authorized to $475 billion (approximately $665 billion in 2024). By October 11, 2012, the Congressional Budget Office (CBO) stated that total disbursements would be $431 billion, and estimated the total cost, including grants for mortgage programs that have not yet been made, would be $24 billion.
