Asian stocks were mixed Monday as traders struggled to maintain momentum from last week's rally, though Shanghai advanced as mainland Chinese markets reopened after a week-long Lunar New Year break.
Even a strong performance on Wall Street was not enough to lift sentiment across the region as data showed the Federal Reserve's preferred gauge of inflation rose in December at its slowest pace in more than a year.
The reading saw dealers ramp up bets on the central bank lifting interest rates this week by just 25 basis points, down from the half-point hike last month, which followed four straight 75-point increases.
The European Central Bank and Bank of England are also due to announce decisions this week.

Oil prices rose on increased demand expectations as China emerges from years of strict Covid controls.
There was little impact on the commodity market from news of a drone strike on an Iranian defence ministry site.
"While oil prices opened higher on the headlines, the risk to global supply seems relatively limited at present," said SPI Asset Management's Stephen Innes.
