Singapore's bellwether economy is expected to grow 3-5%, unchanged from earlier forecasts.

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.

It adjusts its policy via three levers: the slope, mid-point and width of the policy band.
