How Goldman Killed A.I.G.

By WILLIAM D. COHAN

The conventional wisdom has it that the final report of the Financial Crisis Inquiry Commission was a low-budget flop, hopelessly riven by internal political disputes and dissension among the commission’s 10 members. As usual, the conventional wisdom is completely wrong. Actually, the report — and the online archive of testimony, interviews and documents that are now available — is a treasure trove of invaluable information about the causes and consequences of the Great Recession.

For instance, on the exceptionally important but little understood role played by the increasingly lower prices Goldman Sachs placed on the complex mortgage securities on its balance sheet — which helped determine the fate of many of its shakier Wall Street brethren — the commission report, on page 237, is crystalline:

As the crisis unfolded Goldman marked mortgage-related securities at prices that were significantly lower than those of other companies. Goldman knew that those lower marks might hurt those other companies — including some clients — because they could require marking down those assets and similar assets. In addition, Goldman’s marks would get picked up by competitors in dealer surveys. As a result, Goldman’s marks could contribute to other companies recording “mark-to-market” losses: that is, the reported value of their assets could fall and their earnings would decline.
