'DOUBLE TIGHTENING'
Singapore's bellwether economy is expected to grow 3-5%, unchanged from earlier forecasts.
"2022 will be year of double tightening for Singapore - both fiscal and monetary levers will grind tighter," said OCBC's Ling.
The MAS expects core inflation to be 2.0–3.0% this year, from the 1.0–2.0% expected in October. Headline inflation is expected to be 2.5–3.5%, from the earlier forecast range of 1.5–2.5%.
"While core inflation is expected to moderate in the second half of the year from the elevated levels in the first half as supply constraints ease, the risks remain skewed to the upside," the MAS said.
Singapore will release its annual budget on Feb. 18, when the government is expected to announce the timing for an anticipated hike in goods and services tax.
The city-state's economy grew 7.2% in 2021, its fastest pace in over a decade, rebounding from a record 5.4% contraction in 2020. The government has spent more than S$100 billion over the last two years to cushion its economy from the impact of the pandemic.
Instead of interest rates, the MAS manages policy by letting the local dollar rise or fall against the currencies of its main trading partners within an undisclosed band.
It adjusts its policy via three levers: the slope, mid-point and width of the policy band.
