SINGAPORE- Asian equities extended their winning run to scale their highest levels in seven months on Wednesday, with South Korean stocks leading the way, and the Australian dollar hit multi-month highs as surging inflation made higher interest rates more likely.

MSCI's broadest index of Asia-Pacific shares outside Japan advanced 0.4 percent to a seven-month high, with South Korean shares gaining 1.3 percent as trading resumed after the Lunar New Year holidays.

The MSCI gauge has rallied 9 percent so far this year after slumping nearly 20 percent in 2022.

Nikkei gained 0.1 percent and Singapore jumped 1.7 percent.

Globally, stocks have posted strong gains this year after a torrid 2022, based on expectations that inflation is close to peaking and the rise in US interest rates will taper off.

Stronger-than-expected economic data in Europe has eased market worries of a sharp recession in the euro zone as energy prices decline, though interest rates are still seen creeping up.

The euro held near a nine-month peak against the dollar, as trades were encouraged by a rosier growth outlook for the euro zone against signs of a recession looming in the United States.

Australian equity markets slipped 0.2 percent on Wednesday after a shock surge in inflation to a 33-year high last quarter added to the case for the Reserve Bank of Australia to keep raising interest rates.

Investors sharply narrowed the odds on the Reserve Bank of Australia (RBA) lifting its cash rate by a quarter point to 3.35 percent when it meets on Feb 7. Analysts had thought there was some chance the RBA might even pause its tightening campaign, but the pace of inflation put paid to that.

The Kiwi however slid nearly 0.4 percent to $0.648 after New Zealand's annual inflation of 7.2 percent in the fourth quarter came in below its central bank's forecast of 7.5 percent.
