Forming the Financial Stability Oversight Council (FSOC), whose primary responsibility is to keep banks and other financial firms from becoming “too big to fail.”

       Mandating stress tests run by the Federal Reserve to more carefully monitor the largest banks and financial institutions and giant insurance companies. The annual tests make sure very large institutions are prepared for future financial crises. If a bank doesn’t pass the test, the Federal Reserve can suspend share buybacks or put a cap on dividends to ensure that the bank remains strong enough so it can lend to struggling businesses and survive hard times.

       Creating the Consumer Financial Protection Bureau (CFPB), which is intended to protect consumers from risky or abusive financial products. This bureau can regulate companies that sell financial products to consumers and enforce laws against discrimination in consumer finance.

       Creating the Volcker Rule to prevent banks from engaging in speculative trading activities. This rule was named after Federal Reserve Chairman Paul Volcker. Prior to this rule, and leading up to the financial crisis of 2008, banks were creating and then trading highly risky derivatives, most of which became huge liabilities that bankrupted entire financial institutions. American International Group (AIG) was one of the most notorious (see the nearby sidebar “What Led to Dodd-Frank?”). Under this rule, banks can only trade when it’s necessary to run their business, such as currency trading or working to support an agent, broker, or custodian for their customers’ funds.

       Providing for the regulation of derivative trading by the SEC. These are contracts between two parties to exchange financial assets, which can include bonds, commodities, currencies, interest rates, market indexes, or stocks. Regulators have the power to identify risks in the trades and take action before they trigger a financial crisis.

       Requiring hedge funds to register with the SEC. In addition, hedge funds must provide critical information about their trades and portfolios to the SEC, so it can then assess their overall risk.

       Creating the SEC Office of Credit Ratings (OCR), which oversees credit ratings agencies, such as Standard & Poor’s and Moody’s. These credit ratings agencies rank the safety of bonds and impact bond purchase decisions by brokers and individuals.

       Bank regulation was watered down and the rules intended to protect big banks from collapse were changed. Fewer banks are now required to go through stress tests to be sure they can handle a severe downturn.

       The CFPB’s role was weakened in its efforts to investigate subprime lenders. Originally, Congress made the director independent and they were only allowed to be removed for wrongdoing. The Trump administration fought a long battle all the way up to the Supreme Court, which ruled that the director can be fired at will by the president, which makes the director beholden to the political whims of a sitting president.

       The Volcker Rule was loosened so that bank capital requirements are lower and banks can be granted permission to make investments in venture-capital funds, possibly setting the banks on the road to another financial crisis.

       They prepare the required SEC documents and register the new stock offering with the SEC. These documents must include information about the company (its products, services, and markets) and its officers and directors. Additionally, they must include information about the risks the firm faces, how the business plans to use the money raised, any outstanding legal problems, holdings of company insiders, and, of course, audited financial statements.

       They price the stock so it's attractive to potential investors. If the stock is priced too high, the offering could fall flat on its face, with few shares sold. If the stock is priced too low, the company could miss out on potential cash that investors, who buy IPO shares, can get as a windfall from quickly turning around and selling the stock at a profit.

       They negotiate the price at which the stock is offered to the general public and the guarantees they give to the company owners for selling the stock. An investment banker can give an underwriting guarantee, which guarantees the amount of money that will be raised. In this scenario, the banker buys the stock from the company and then resells it to the public. Usually, an investment banker puts together a syndicate of investment bankers who help find buyers for the stock.Another method that's sometimes used is called a best efforts agreement. In this scenario, the investment banker tries to sell the stock but doesn't guarantee the number of shares that will sell.

       They decide which stock exchange to list the stock on. The New York Stock Exchange (NYSE) has the highest level of requirements. If a company wants to list on this exchange, it must have a pretax income of at least $10 million over the last three years and 2,200 or more shareholders. The NASDAQ has lower requirements. Companies can also sell stock over the counter, which means the stock isn't listed on any exchange, so selling the stock both as an IPO and after the IPO is much harder.
