Major bourses in Asia largely fell on Monday, as traders braced for a key policy decision from the US Fed amid concerns over soaring inflation. The Hang Seng shed 0.9%, as Hong Kong battles rising COVID-19 cases ahead of the Lunar New Year holiday. Shares in China were almost flat, as the PBoC cut the 14-day reverse repo rate by 10 bps to 2.25% following a reduction of a slew of short- and medium-term rates last week.
