WASHINGTON - The Federal Reserve may be about to turn more aggressive in its regulation of the financial system.
Fed Chair Janet Yellen suggested Tuesday that current regulatory rules might not be enough to prevent the kind of risk-taking that triggered the 2008 financial crisis and nearly toppled the entire banking system.
She said the largest U.S. banks may need to hold additional capital to withstand periods of financial stress. Non-banks with deep reaches into the financial system might also need to meet tougher rules, she said. Such firms range from money market mutual funds to private equity and hedge funds.

Yellen said Tuesday, that the largest U.S. banks might need to hold additional capital to withstand periods of financial stress.
Yellen told a banking conference in Atlanta that current rules on how much capital banks must hold to protect against losses don't address all threats. The Fed's staff is considering what further measures might be needed, she said.
At the same time, Yellen said the Fed would review the likely effects of imposing stricter rules on banks. Banks and their advocates have warned that further tightening bank regulation would lead to reduced lending to businesses and financial institutions and could slow economic growth.
Analysts said Yellen's message echoed remarks that Daniel Tarullo, a Fed governor and the board's point person on bank regulatory issues, has made in the past. They said it could be a sign that the Fed under Yellen will take a more assertive stance toward bank regulation.
In her speech, Yellen said further actions to address risks, such as requiring firms to hold more capital, would likely apply only to the largest, most complex banks. But she suggested that other requirements could be applied more broadly to medium-size banks and non-bank financial institutions.
Karen Shaw Petrou, an analyst who heads Federal Financial Analytics in Washington, said Yellen also appeared to be signaling a desire to ensure that in tightening rules for big banks, regulators don't just drive risky behavior into less regulated areas of the financial system. These areas are often called the shadow banking system.
