Understanding the CPI inflation of India is crucial. As many of the economic metrics are directly dependent on it. Hence, in this note, I plan to tell the story through charts. These charts are not static, they are dynamic. As it enables the readers to drill down to get further insights into not only the inflationary trends but also the ability to see the picture from different angles based on chosen metrics from the dropdown menus.

CPI — Main Category

Here is the screenshot of the trend of the last 10 months of the CPI main category of items.

Key takeaways:- a) Fuel inflation is on a downward trend; b) Food inflation is shown a sharp decline after a peak on Sept 22, and it has a large impact on the overall inflation as its corresponding weight on the general index is 45.9%; c) Housing inflation is on an increasing trend.

CPI — Sub Category
