[T]he financial crisis that began in the summer of 2007 has posed a major problem. We had grown rather accustomed to singing the praises of free financial markets. The crisis threatens to discredit them.
But this crisis was not the result of deregulation and market failure. In reality, it was born of a highly distorted financial market, in which excessive concentration, excessive leverage, spurious theories of risk management and, above all, moral hazard in the form of implicit state guarantees, combined to create huge ticking time-bombs on both sides of the Atlantic.

They could and did assume that they enjoyed an implicit government guarantee...
During the crisis it was often said that officials at the Federal Reserve and Treasury would do "whatever it takes" to avoid a Great Depression.
