The U.S. Senate passed a reform bill in May 2010, following the House which passed a bill in December 2009. These bills must now be reconciled. The New York Times provided a comparative summary of the features of the two bills, which address to varying extent the principles enumerated by the Obama administration. For instance, the Volcker Rule against proprietary trading is not part of the legislation, though in the Senate bill regulators have the discretion but not the obligation to prohibit these trades.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What rule against proprietary trading was not part of legislation passed by either the Senate or House?
Volcker Rule
