In 1997, Rubin and Federal Reserve chairman Alan Greenspan strongly opposed giving the Commodity Futures Trading Commission oversight of over-the-counter credit derivatives when this was proposed by Brooksley Born, the head of the CFTC. Rubin's role was highlighted in a Public Broadcasting Service "Frontline" report, "The Warning". Over-the-counter credit derivatives were eventually excluded from regulation by the CFTC by the Commodity Futures Modernization Act of 2000. According to the "Frontline" documentary, they played a key role in the 2008 financial crisis.
