WASHINGTON (AP) — Treasury Secretary Tim Geithner said Tuesday that the recent $2 billion trading loss by JPMorgan "helps make the case" for tougher rules on financial institutions, as regulators continue to implement the 2010 law aimed at policing Wall Street.

Geithner said that the Federal Reserve, the Securities and Exchange Commission and the Obama administration are "going to take a very careful look" at the JPMorgan incident as they implement new regulations like the so-called "Volker Rule," which bans banks from making bets with firm money.

"The Fed and the SEC and the other regulators — and we'll be part of this process — are going to take a very careful look at this incident of course, and make sure that we review the implications of what that means for the design of these remaining rules," Geithner said at a Washington event hosted by the Peter G. Peterson Foundation.
