(Sharecast News) - Asia-Pacific markets displayed a mixed performance on Wednesday, with Australia's benchmark surging to an all-time high, buoyed by strong performances in several key sectors.

Japanese stocks also saw solid gains, amid reports of increased business optimism among large manufacturers.

"Asian stocks rose, joining a global surge, as the anticipation of the Fed starting to reduce interest rates led to a rush into riskier sectors of the market," said TickMill market analyst Patrick Munnelly.

"The MSCI Asia Pacific Index, which measures regional benchmarks, rebounded after a three-day decline following the record highs in US equities, propelling global stocks to a new peak.

"However, the index's earlier gains were tempered by a drop in Japanese stocks after the US cautioned its allies about stricter trade regulations in the China crackdown."

Munnelly added that traders in Hong Kong and mainland China awaited further details from the Third Plenum.

"Risk appetite seems to have returned in Asia as concerns about geopolitical and trade threats sparked by the increasing prospects of a Donald Trump administration have eased.

"The optimism surrounding the Fed's potential rate cut, coupled with signs of a retail recovery in the US, has bolstered sentiment."

Japanese manufacturers' confidence increases, Singapore exports fall

In economic news, Japanese authorities were suspected of intervening in the currency market last Thursday and Friday, with CNBC reporting that it spent around JPY 6trn to stabilise the yen.

The currency had weakened to JPY 161.82 against the dollar last Wednesday before strengthening to JPY 157.41 the next day.

Meanwhile, the latest Reuters Tankan survey revealed increased business confidence among Japanese manufacturers in July, while the service sector showed a decline.

The sentiment index for manufacturers rose to +11, up five points from June, marking its first increase in four months.

However, manufacturers predicted a slight dip to +10 in the coming three months.

Conversely, the service sector index fell to +26 from +31, with non-manufacturers expecting it to rise slightly to +27 by October.

The survey came two weeks before the Bank of Japan reviews its policy on 30-31 July.

In Singapore, exports fell more than anticipated in June, highlighting ongoing challenges for the trade-dependent economy.

Official data showed non-oil domestic exports decreased by 8.7% year-on-year, significantly more than the 1.3% contraction forecasted in a Bloomberg survey.

That followed a revised 0.7% decline in May.

On a month-on-month seasonally adjusted basis, exports dipped by 0.4% in June.

So far, exports had contracted in five out of six months this year.
