Tech titans helped drive gains in the Nasdaq and S&P 500 after producer price index data broadly met expectations, tempering worries about inflation following Wednesday's figures showing a third successive upside miss in consumer prices.

The CPI figures followed a series of indicators suggesting the world's number one economy remained resilient and the jobs market strong despite interest rates sitting at two-decade highs and inflation still well above the Federal Reserve's target.

That has seen investors trim their rate cut bets from six at the start of the year to two now, while former Treasury secretary Lawrence Summers has even warned a hike could not be ruled out.

Central bank officials were reluctant to give their full backing to any reductions soon.

New York Fed chief John Williams said "tremendous progress" had been made in the battle against inflation but there was little need to move in the "very near term", while Richmond boss Thomas Barkin added that decision-makers could take their time.

Their Boston counterpart Susan Collins said the latest data "implies that less easing of policy this year than previously thought may be warranted".

While US traders pounced on the producer price numbers, Michael Shaoul at Marketfield Asset Management said: "Although we understand the relief with which this report will be received, there is nothing very encouraging contained within it -- and the best that can be said is that there was 'no new bad news' either."

Asian traders were also less impressed.

Hong Kong, Shanghai, Sydney, Seoul, Singapore and Wellington were all in the red, while Tokyo, Taipei and Manila edged up.

Dimming hopes for rate cuts continued to support the dollar, which surged to another 34-year high above 153 yen, putting Japanese officials in the spotlight after they said they were ready to intervene in markets to support their currency.

Still, gold rose on the back of the PPI reading, pushing it to a new record of 2,395.48 with traders also seeking it out as a safe haven owing to ongoing concerns about the Middle East conflict.

Attention is now turning to the corporate reporting season, which gets underway in earnest later in the day with banking giants JPMorgan and Citibank among those to open their books.

Analysts said that while reducing interest rates would be a major boost for equities, investor optimism about company profits was crucial.

"The recent run of solid US economic data releases has helped build expectations for companies to report encouraging revenue figures and guidance," said National Australia Bank's Rodrigo Catril.
