Asian stocks rise as PBOC eases fear on yuan

Asian stocks mostly erased losses to rise on Thursday, after the People's Bank of China (PBOC) reiterated that there was no basis for continued currency depreciation.

In a closely-watched press conference in Beijing, the Chinese central bank said the country's strong economic environment, sustained trade surplus, sound fiscal position and deep foreign exchange reserves remain "strong support" for the exchange rate, while adding that it will monitor "abnormal" cross border flows.

Prior to that, the PBOC set the midpoint rate for the at 6.4010 per dollar, weaker than the previous day's close of 6.3870, sending the currency down 0.4 percent to 6.4067.

Mainland markets up

China's Shanghai Composite index reversed early losses to lurch higher by more than 1 percent in late-afternoon trading. The Shanghai bourse eventually closed up 1.8 percent after choppy trade saw the index swinging between 1 percent on either side of the flatline.

Mirroring the moves in the benchmark index, the blue chip CSI300 index and Shenzhen Composite ended up 1.5 and 2.2 percent, respectively.

After coming under intense selling pressure in the past two trading sessions, Chinese carriers enjoyed a reprieve on Thursday, with China Eastern Airlines and Air China gaining 4.1 and 2.8 percent, respectively. Worries that a weaker currency could increase borrowing costs and fuel bills of Chinese carriers have weighed on airline shares for the past two trading sessions.

Analysts attributed the earlier declines to "confusion" in the mainland equity markets. "We had confusion in the markets last month due to self-inflicted wounds with regards to curbs on margin trading. It's confusion again today... as the [PBOC's comments] adds to further uncertainty and questions about the opacity in decision making," Stephen Davies, CEO at Javelin Wealth Management, told CNBC.

Japan's benchmark index fell into negative territory after the yuan fixing, but quickly hurled itself back above the flatline on the back of expectations that the yuan's depreciation could prompt further easing in Japan.

The [Bank of Japan] minutes out yesterday showed there were significant concerns by the central bank's board members about hitting the 2 percent inflation target by September 2016," IG's market analyst Angus Nicholson wrote in a note. "With deflationary pressures from the yuan's devaluation, there is going to be a high likelihood of further BOJ easing to stop an increase in the yen, possibly as soon as October."
