HONG KONG, RAW – Asian shares are on edge, hurt by persistent uncertainty around the fate of debt-ridden China Evergrande even as more risk appetite drove gains for Wall Street and US benchmark Treasury yields.

MSCI’s broadest index of Asia-Pacific shares outside Japan lost 0.1 per cent and was set for a weekly loss of 0.68 per cent. Australian shares fell 0.41 per cent while the Hong Kong benchmark was mostly flat.

Japan’s Nikkei rose 1.93 per cent, however, catching up on global gains after a public holiday. Chinese blue chips reversed early losses to gain 0.6 per cent after a cash injection from the central bank brought its weekly injection to 270 billion yuan ($A57 billion) – the largest since January.

US stock futures, the S&P 500 e-minis, were up 0.5 per cent.

Investors continue to worry about the fate of property developer Evergrande, which faces an interest payment deadline that due on Thursday. Its shares fell 5.2 per cent on Friday after bouncing 17.6 per cent a day earlier.

Ray Ferris, chief investment officer for South Asia at Credit Suisse, said while investors were jittery about prospects for China due to woes in the property sector and a slew of regulatory changes, there was positive sentiment elsewhere.

“Growth in the large developed economies is above trend, likely to remain above trend, and monetary policy remains very supportive of asset prices likely all the way through the middle of next year, he said.

“Every once in a while shocks to the system give us a correction, but these are more shallow than in the last several decades because of the weight of money out there that needs a home.”

The Dow Jones Industrial Average, the S&P 500 and the Nasdaq Composite all gained more than one per cent overnight, with the Federal Reserve’s stance on tapering stimulus – set out on Wednesday – appearing to reassure investors interest rates hikes remain a way off, even if the tapering of its massive asset-purchase program is set to start this year.

That risk-on sentiment weighed on the US dollar, which dropped sharply overnight against a basket of its peers, falling from near a one-month high to a week low. It then rested in Asian hours.

The yield on benchmark 10-year Treasury notes was also little changed in early Asian hours at 1.4267 per cent, having risen to its highest in two and a half months after a rate rise by the Norwegian central bank and hawkish remarks from the Bank of England, both on Thursday, reinforced Wednesday’s hawkish remarks from the Federal Reserve’s policy committee.

Oil dropped back after hitting two-month highs the day before.

US crude shed 0.27 per cent to $US73.11 a barrel. Brent crude lost 0.14 per cent to $US77.14 per barrel.

Gold regained some ground on Friday, with the spot price rising 0.5 per cent to $1751 per ounce having fallen more than one per cent the day before as higher yields hurt the non-interest bearing asset.
