Singapore's consumer price index has been rigorously tabulated by the department of statistics for all to see.
Whether you think inflation is high or not depends on many factors, such as whether your income/assets can keep up, your consumption basket mix, your frame of mind, etc. With that said, Singapore's inflation is in general lower than other countries despite robust economic growth, partially due to the strengthening Singapore dollar making imports affordable.
Economist in general view the past 30 years as low inflation because of excess capacity and cheap outputs from China as the factory of the world. The next 30 years will be deflationary because of AI related productivity gains. It'll be a world of abundance.
Lol!
