First of all, analyzing whether there is a bubble economy in a local economy has nothing to do with deposit and loan interest rates, because this is the macro-control of the country. Of course, if we analyze the economic history of a country, we must analyze the deposit and loan interest rates.

Secondly, to analyze whether there is a bubble in a local economy, we mainly analyze it from the following points: 1, the proportion of bank loans in the real estate sector to the whole bank loan scale; 2. The ratio of house price to per capita income; 3. Real GDP growth rate and bank loan growth rate of real estate industry. In Japan, before the economic bubble burst, the above three indicators were: 1, and the proportion of bank loans to the real estate sector in the whole bank loan scale surged from 18% to more than 30%; 2. The price of real estate has climbed to more than five times the per capita income, making it difficult for families with average income to buy; 3. The growth rate of bank loans to the real estate industry far exceeds the actual GDP growth rate.

Finally, the CPI you mentioned. If CPI continues to rise, it means there is inflation. If you analyze a place, you need a lot of data. You can refer to other documents.
