The U.S. dollar sagged to eight-month lows on Thursday as the U.S. government shutdown dragged on with no end in sight, though share markets found comfort in expectations major central banks might now have to stay super-loose for longer.
Also helping sentiment was an upbeat survey on China's huge services sector, an antidote to a disappointing report on manufacturing earlier in the week.
MSCI's broadest index of Asia-Pacific shares outside Japan moved 0.8 percent higher, after a flat performance on Wednesday.
Japan's Nikkei recovered early losses to be steady on the day, while Australian shares added 0.7 percent.
A meeting between U.S. President Barack Obama and congressional leaders produced nothing but blame and counter-blame, dimming hopes of an early end to the budget impasse.

The ceiling is far more important than the shutdown since it could lead to an unprecedented default by the United States, an outcome the market assumes is unthinkable.
"To the extent that we have never been in a situation where the debt ceiling has not been raised, there is a high degree of uncertainty over how events will transpire," said Elliot Clarke, an economist at Westpac in Sydney.

That in turn has helped drag yields on the benchmark 10-year U.S. Treasury note down to 2.62 percent,
