President Barack Obama has signed legislation to increase the US debt ceiling and avert a financial default, after Congress voted in favour of a bipartisan compromise deal. The bill cleared its final hurdle in the Senate by 74 votes to 26, after negotiations went down to the wire. It raises the debt limit by up to $2.4tn (£1.5tn) from $14.3tn, and makes savings of at least $2.1tn in 10 years. But the bill's passage failed to lift financial markets. On Wall Street stocks ended Tuesday down by more than 2%, amid poor consumer spending data for June. Japan's Nikkei index followed suit, finishing Wednesday morning down by about the same amount. Moody's rating agency reacted to the bill by placing Washington's AAA credit score under a "negative outlook". Chinese credit agency Dagong downgraded its rating of the US from A+ to A, Xinhua news agency reported. The bill's signing came just 10 hours before the expiry of a deadline for Washington to raise its borrowing limit, after drawn-out talks between Republicans, Democrats and the White House. Without a deal to raise the debt ceiling, the US would have been unable to meet all its bills, the treasury department had warned. Speaking at the White House shortly after the decisive vote in the Senate, President Obama said it was "pretty likely that the uncertainty surrounding the raising of the debt ceiling for businesses and consumers has been unsettling". "It's something we could have avoided entirely," he added. The president said more action was needed, saying it was impossible for the US to "close the deficit with just spending cuts". He urged Congress to now look to boost the economy through measures to create jobs and increase consumer confidence. "We can't balance the budget on the backs of the very people who have borne the biggest brunt of this recession," President Obama said, reprising one of his key themes of recent weeks. Lawmakers lament In Tuesday's Senate vote, the bill was opposed by six Democrats and 19 Republicans. Some Democratic and Republican lawmakers have bitterly opposed the legislation in recent days, saying it offered too much of their opponents' agenda. But the legislation still received many of their votes in the House and Senate as lawmakers heeded warnings that the US would default on its debts if Congress did nothing. "This is a time for us to make tough choices as compared to kick the can down the road one more time," Republican Senator Jerry Moran said following the vote. Speaking after the vote in the Senate, Democratic majority leader Harry Reid echoed the discontent of some in Congress, saying "neither side got all it wanted, each side laments what it didn't get". "Today, we made sure that America will pay its bills, now it's time to make sure all Americans can pay theirs," Mr Reid added. Before the bill's passage, Senate Republican leader Mitch McConnell praised the outcome, saying: "Together, we have a new way of doing business in Washington." The legislation passed in the House of Representatives by a clear majority on Monday evening. Source: BBC
