Sorted by total, highest first. Every row is indexed to the last month complete before the first day in office ("from" marks a start that had to move because that period had no data, or because the period cut it); Levels are per cent changes, rates are differences in pp; "per year" compounds levels and divides rates. Tenures with under 12 months, or under three observations, are left out. % change on a year earlier · SingStat Table Builder (M213781), consumer price index, all items, change on the same month a year earlier · Singapore data · as of Sep 2026.
