Asian stock markets wobble -

HONG KONG, Sept 24 (Reuters): Asian shares were on edge on Friday, hurt by persistent uncertainty around the fate of debt-ridden China Evergrande, even as increased risk appetite drove US stocks and Treasury yields higher.

MSCI's broadest index of Asia-Pacific shares outside Japan was little changed after falling 0.7 per cent this week, poised for its third weekly loss in a row.

Australian shares fell 0.4 per cent, while the Hong Kong benchmark was mostly flat.

Japan's Nikkei rose 2 per cent, however, catching up with global gains after the market was closed for a public holiday. Chinese blue chips reversed early losses to gain 0.3 per cent after a cash injection from the central bank brought its weekly injection to 270 billion yuan ($42 billion) - the largest since January.

US stock futures, the S&P 500 e-minis, were up 0.5 per cent, while European stock futures and British stock futures , slipped.

Investors continued to worry about the fate of property developer Evergrande which missed an interest payment deadline on Thursday and has entered a 30-day grace period.

Evergrande shares fell 11 per cent on Friday, extending losses following a Reuters report that some offshore bondholders had not received interest payments by the Thursday deadline. It rallied 17.6 per cent the previous day after the company said it had agreed to settle interest payments on a domestic bond.

Global investors have been on tenterhooks as debt payment obligations of Evergrande, labouring under a $305 billion mountain of debt, triggered fears its malaise could pose systemic risks to China's financial system.
