SYDNEY Oct 17 (Reuters) - Banking stocks led a modest rise in Australian shares on Thursday morning, as global markets breathed a sigh of relief after the U.S. Senate approved a deal to break a fiscal impasse that brought the world's biggest economy to the brink of a debt default.
Speaking after the Senate voted to end the fiscal logjam, but before the House of Representatives took a vote, President Barack Obama said the government will reopen immediately after he signs the bill, ending a 16-day shutdown.
The deal will reopen the government through Jan. 15 and raise the debt ceiling until Feb. 7.
"A decision's gone down to the wire, and very much confirmed traders' expectations that there was going to be resolution to this deadline," said City Index market maker and trader Kara Ordway in Sydney.
The S&P/ASX 200 index added 23.2 points to 5,286.1 by 0033 GMT. The benchmark tacked on a modest 0.1 percent on Wednesday.
The positive mood reflected relief in global markets, with Wall Street rallying more than 1 percent on Wednesday.
Still, there was some caution ahead of the House vote on the debt deal.
"In terms of the vote, it will be harder to push through the House of Representatives and that might be slightly more rocky in terms of sentiment this afternoon," Ordway said.
Australia's Boral stole the limelight in the morning session.
The building materials maker's stock jumped 5.3 percent, the biggest one-day surge in nine months, after it announced a $1.6 billion plasterboard joint venture with its U.S. peer USG Corp .

A handful of underwhelming earnings reports capped the broader market's gains.
