Americans demanded retribution from the mortgage lenders whose subprime loans defaulted and from investment bankers whose mortgage-backed securities sharply declined in value in 2007, leading to financial panic and the Great Recession. From 2008 to 2019, the federal government extracted hundreds of billions in fines from dozens of corporations, but few individual business executives were held accountable, and no senior banker was convicted of a crime. I use the trial court record of five government enforcement cases against individuals to explain this apparently anomalous result. I conclude that, in addition to a lack of funding, the prosecution effort was hindered by the government’s erroneous selection of cases to pursue. Further, the diffused nature of decision making in the mortgage finance market made it difficult to prove that any one senior-level participant had the criminal intent necessary for a conviction or a Securities and Exchange Commission civil fine or injunction. The trial results also support the argument that the growth and consolidation of investment banks from 1990 to 2008 created incentives for misconduct within the firms.
