U.S. Treasury Secretary Timothy Geithner will soon propose an overhaul of the financial regulatory system that is expected to give the Federal Reserve powers to monitor broad economic risks, a Treasury spokesman confirmed on Monday.

Geithner is due to soon outline proposed changes that are also expected to include tougher capital standards for banks, according to a report in the Wall Street Journal that a Treasury spokesman said is accurate.

The administration's goal is to unveil its proposals before the meeting of the heads of state of the Group of 20 rich and developing economies in early April, the report said.

The rules are further expected to aim to ensure that banks cannot shop among different regulatory agencies to obtain the most lenient supervision and require more transparency and stricter rules for the way money flows between banks.

Consolidated consumer protection enforcement is also among contemplated changes.
