The 'too big to (let) fail' theory asserts that certain corporations, particularly financial institutions, are so large and so interconnected that their failure would be disastrous to the greater economic system, and that they therefore must be supported by government when they face potential failure. The colloquial term 'too big to fail' was popularized by U.S. Congressman Stewart McKinney in a 1984 Congressional hearing, discussing the Federal Deposit Insurance Corporation's intervention with Continental Illinois. The term had previously been used occasionally in the press.

The term had previously been used occasionally in the press. Proponents of this theory believe that some institutions are so important that they should become recipients of beneficial financial and economic policies from governments or central banks. Some economists such as Paul Krugman hold that economies of scale in banks and in other businesses are worth preserving, so long as they are well regulated in proportion to their economic clout, and therefore that 'too big to fail' status can be acceptable. The global economic system must also deal with sovereign states being too big to fail. Opponents believe that one of the problems that arises is moral hazard whereby a company that benefits from these protective policies will seek to profit by it, deliberately taking positions (see asset allocation) that are high-risk high-return, as they are able to leverage these risks based on the policy preference they receive. The term has emerged as prominent in public discourse since the 2007–08 global financial crisis. Critics see the policy as counterproductive and that large banks or other institutions should be left to fail if their risk management is not effective. Some critics, such as Alan Greenspan, believe that such large organisations should be deliberately broken up: 'If they're too big to fail, they're too big'. More than fifty prominent economists, financial experts, bankers, finance industry groups, and banks themselves have called for breaking up large banks into smaller institutions. In 2014, the International Monetary Fund and others said the problem still had not been dealt with. While the individual components of the new regulation for systemically important banks (additional capital requirements, enhanced supervision and resolution regimes) likely reduced the prevalence of TBTF, the fact that there is a definite list of systemically important banks considered TBTF has a partly offsetting impact. Federal Reserve Chair Ben Bernanke also defined the term in 2010: 'A too-big-to-fail firm is one whose size, complexity, interconnectedness, and critical functions are such that, should the firm go unexpectedly into liquidation, the rest of the financial system and the economy would face severe adverse consequences.' He continued that: 'Governments provide support to too-big-to-fail firms in a crisis not out of favoritism or particular concern for the management, owners, or creditors of the firm, but because they recognize that the consequences for the broader economy of allowing a disorderly failure greatly outweigh the costs of avoiding the failure in some way. Common means of avoiding failure include facilitating a merger, providing credit, or injecting government capital, all of which protect at least some creditors who otherwise would have suffered losses. ... If the crisis has a single lesson, it is that the too-big-to-fail problem must be solved.' Bernanke cited several risks with too-big-to-fail institutions: Prior to the Great Depression, U.S. consumer bank deposits were not guaranteed by the government, increasing the risk of a bank run, in which a large number of depositors withdraw their deposits at the same time. Since banks lend most of the deposits and only retain a fraction in the proverbial vault, a bank run can render the bank insolvent. During the Depression, hundreds of banks became insolvent and depositors lost their money. As a result, the U.S. enacted the 1933 Banking Act, sometimes called the Glass–Steagall Act, which created the Federal Deposit Insurance Corporation (FDIC) to insure deposits up to a limit of $2,500, with successive increases to the current $250,000. In exchange for the deposit insurance provided by the federal government, depository banks are highly regulated and expected to invest excess customer deposits in lower-risk assets.
