Senate kills proposed OTC energy regulation

The measure was defeated on a routine procedural vote that required 60 affirmative votes for the amendment to advance. Feinstein’s proposals received 48 votes, forcing her to withdraw her amendment, admitting it lacked sufficient support "at this time".

Texan Republican Senator Phil Gramm led the opposition to the proposals, with support from Alan Greenspan, chairman of the Federal Reserve, and Paul O'Neill, the US Treasury secretary.

The International Swaps and Derivatives Association, and other trade associations, also urged the Senate to vote against the proposals, noting that Feinstein’s amendments unfairly applied to OTC metals derivatives, which have no connection to either the Enron collapse or the Californian energy crisis.

Feinstein had previously rejected a request from Gramm, the top-ranking Republican on the Senate Banking Committee, to exempt metals derivatives and to drop price-transparency requirements from her proposed reforms.
