The statistical caliber is inconsistent. Inflation generally refers to CPI index. For example, in economics, more than 6% is inflation, and the goods counted by this CPI are generally final consumer goods, such as steamed bread and bicycles. Futures commodity price index calculates the price of main raw materials or commodities, that is, the price of wheat or steel. Generally speaking, if the price of raw materials rises a little, it will go through several processes and circulation channels to become the final consumer goods, and the price will increase exponentially.

Generally speaking, inflation is an economic definition or people's livelihood significance, and even the language of news media reflects the phenomenon, but it cannot accurately reflect the magnitude and speed of price increase. The futures commodity price index accurately reflects the time and magnitude of price changes, and the inconsistency between them is understandable.
