(Reuters) - Asian currencies strengthened on Friday as the dollar languished on fears over a U.S. government shutdown and as China's strong economic growth figures boosted sentiment in the region.
The dollar index was down 0.165 at 90.35, hovering near the three-year low of 90.104 it hit on Thursday.
The U.S. House of Representatives on Thursday passed a bill to fund government operations through Feb. 16 and avoid agency shutdowns this weekend when existing money expires. The bill must still be approved by the Senate, where it faces some uncertainties.
"If a shutdown occurs, history tells us the dollar will sell off marginally in the ensuing weeks but the scope for weakness will be somewhat limited," said Stephen Innes, head of trading in Asia-Pacific for Oanda in Singapore.
"We should expect investors to look past Washington contempt regardless of the length of the interruption but apparently from a more risk adverse perspective."
