In its November 2009 monthly report, the Congressional Oversight Panel (COP) studied government-backed guarantees under the Troubled Asset Relief Program. The COP stated in the report that the asset guarantees from the Treasury Department, the Federal Reserve and the Federal Deposit Insurance Corporation helped calm panic in financial markets, with minimal cost to taxpayers to date. The report raised concerns about moral hazard created by the guarantees and recommended greater disclosure by the Treasury Department with regard to government-guaranteed assets of Citigroup Inc. COP Chair Elizabeth Warren commented on these issues in an interview on CNBC.
