One year in the making, a sweeping overhaul of Wall Street rules forged in the aftermath of a financial crisis cleared congressional negotiations early Friday and headed to the House and Senate for final votes.
Lawmakers hope to have a bill on President Barack Obama's desk by July 4.
Success came at 5:39 a.m., hours after Obama administration officials helped broker a deal that cracked the last impediment to the bill — a proposal to force banks to spin off their lucrative derivatives trading business.
The legislation, the most ambitious rewrite of financial regulations since the Great Depression, touches on an exhaustive range of financial transactions, from a debit card swipe at a supermarket to the most complex securities deals cut in downtown Manhattan.
Eager to avoid a recurrence of the 2008 financial meltdown, lawmakers set up a warning system for financial risks, created a powerful consumer financial protection bureau to police lending, forced large failing firms to liquidate and set new rules for financial instruments that have been largely unregulated.
"It took a crisis to bring us to the point where we could actually get this job done," Senate Banking Committee Chairman Christopher Dodd said.
In its breadth, the legislation would affect working class homebuyers negotiating their first mortgage as well as international finance ministers negotiating international regulatory regimes.
The bill came together in during a time of high unemployment for American workers, huge bonuses for bankers and rising antipathy toward bank bailouts.
"It is reassuring to know that when public opinion gets engaged it will win," said Rep. Barney Frank, the chairman of the House-Senate panel that merged House and Senate bills into one piece of legislation.
House negotiators voted a party line 20-11 in favor of the final agreement; senators voted 7-5, also along party lines.
Republicans complained the bill overreached and tackled financial issues that were not responsible for the financial crisis.
Frank and Dodd set a furious pace for lawmakers in their last day of talks, pushing them into the late hours to resolve the most nettlesome differences between the House and Senate.
Their goal, in part, was to equip Obama with a legislative agreement as he meets with leaders of the Group of 20 nations this weekend in Toronto.
"Congress has shown that America is ready to lead by example," Treasury Secretary Timothy Geithner said.
Shortly after 5 a.m., Rep. Paul Kanjorsky, D-Pa., moved to officially name the legislation the Dodd-Frank bill. Dodd, who will retire at the end of this term, jokingly objected before lawmakers voted unanimously in favor. Aides and administration officials broke into applause.
While the legislation addressed the causes of the last meltdown — and more — it left for later any restructuring of the government-related mortgage giants Fannie Mae and Freddie Mac. Time and again, Republicans tried to shift the debate to the mortgage purchasing firms, to no avail.
The government took over Fannie and Freddie in 2008 after they suffered heavy loan losses in the housing crash. Their collapse has cost $145 billion and the Obama administration has pledged to cover unlimited Fannie and Freddie losses through 2012, lifting an earlier cap of $400 billion.
While many tough provisions in the bill survived, securing the votes of moderate Democrats in the House and a handful of Republicans in the Senate meant softening some provisions in the bill.
Under the bill, banks could lose billions in lucrative trading business, though negotiators blunted some of the harsher measures under consideration.
In a blow to Obama, the consumer protection agency would not regulate auto dealers, even though they assemble loans for millions of car buyers. Payday lenders and check cashers would be regulated, but enforcement would be left to states or the Federal Trade Commission.
To pay for the costs of the bill, negotiators agreed to assess a fee on banks with assets of more than $50 billion and hedge funds of more than $10 billion in assets to raise $19 billion over 10 years.
The House-Senate panel numbered 43 total negotiators, though not all attended at all times.
The final agreement capped an all-night marathon session of public and private deal making. House Speaker Nancy Pelosi stepped in to press agreement on one of the final obstacles.
As they worked toward the home stretch early Friday, negotiators softened a contentious Wall Street restriction that would force large bank holding companies to spin off their lucrative derivatives business.
The deal, negotiated between the White House and Sen. Blanche Lincoln, D-Ark., eliminated one of the last major sticking points. Congressional leaders were eager to wrap the bill up, with hopes of getting final House and Senate passage next week.
Derivatives are complex securities often used by corporations to hedge against market fluctuations. But they also have become speculative instruments for financial institutions, the most notorious of which were credit default swaps that hedged against loan failures.
In the House, moderate Democrats and members of the New York congressional delegation fought to remove Lincoln's language.
Under the agreement banks would only spin off their riskiest derivatives trades. Banks get to keep some of their lucrative business based on trades in derivatives related to interest rates, foreign changes, gold and silver. They could even arrange credit default swaps, the notorious instruments blamed for the meltdown, as long as they were traded through clearing houses. Banks also would be allowed to trade in derivatives with their own money to hedge against market fluctuations.
Negotiators also limited the ability of banks to carry out their own high-risk trades or invest in hedge funds and private equity funds.
Bank holding companies that have commercial banking operations would not be permitted to trade in speculative investments. But negotiators agreed to let bank holding companies invest in hedge funds and private equity funds, setting an investment limit of no more than 3 percent of their capital. There are no such conditions on banks now.
