Asian stocks reverse losses as China tech roars back

The greenback stabilised after two consecutive days of decline, with the dollar index up 0.2% at 97.438. Against the yen, the dollar was up 0.3% at 148.05.

U.S. stock futures were last up 0.2%, recovering from a dip on Wall Street on Tuesday. The S&P 500 sank 0.6% to mark its biggest one-day loss in three weeks, after remarks by Federal Reserve Chair Jerome Powell on Tuesday.

"U.S. equities and bond yields declined because Fed Chair Jerome Powell’s speech explicitly described equities as 'fairly highly valued' and acknowledged that there was no 'risk-free path' for policy," DBS analysts wrote in a note. "He did not commit to aggressive rate cuts due to the challenging situation of balancing the upside risk to inflation with the downside risk to employment."

Asian stocks are trading near a four-year high and remain on track this month for their best monthly performance in a year, following weakness in the dollar, a surge in regional technology stocks and a resumption of the Federal Reserve's policy easing cycle.

Australian shares were a notable drag on the Asian benchmark on Wednesday, down 0.9%, extending losses after a bigger-than-expected rise in consumer prices in August.

"Although the RBA won’t pay much heed to the pickup in headline inflation, the strength in core inflation will give it pause for thought," Capital Economics analysts wrote in a research note.

Japan's Nikkei stock index was last trading up 0.3%, reversing earlier declines. Traders have ramped up bets on further U.S. rate cuts, with Fed funds futures implying a 91.9% chance of a rate cut at the central bank's October meeting, up from a 89.8% probability on Tuesday, according to the CME Group's FedWatch tool. Longer-dated U.S. government bonds attracted buyers, with the yield on benchmark 10-year Treasury notes falling to 4.1042%, compared with its U.S. close of 4.118% on Tuesday. The two-year yield, which rises with traders' expectations of higher Fed funds rates, fell to 3.5673% compared with a U.S. close of 3.57%.

U.S. economic data released on Tuesday stoked growth concerns, with purchasing managers' index (PMI) data from S&P Global showing business activity slowed for a second straight month in September.

"The S&P PMIs were softer in the September preliminary release, but both remain in expansion and are within the range of the last few months," Citi analysts wrote in a research note. But they pointed to more weakness in the details than implied in the headline numbers.

"The composite output prices index fell to the lowest level since April with anecdotes mentioning that firms are having difficulty passing on higher costs to consumers due to weak demand and more competition," the analysts said. In oil markets, Brent crude was last up 0.1% at $67.71 per barrel, after a deal to resume exports from Iraq's Kurdistan stalled, pacifying some investor concerns that the restart would exacerbate worries about global oversupply. Gold was slightly higher after hitting a record high on Tuesday, with spot gold last up 0.3% at $3,773.36 per ounce.
