The Consumer Price Index, which is a key economic indicator that acts like a magnifying glass which allows us to deep dive into trends reflecting average change in cost of purchasing a specific basket of goods and service over a period of time. Why is this important in terms of our daily live consumption?
This is because when CPI goes up, it means that the cost of our items (think groceries, clothes, medical expenditure) is going up. This phenomenon in economic terms is known as inflation. In simple terms, this would feel like your paycheck shrinking even when your salary has not actually changed. In contrast if CPI goes down, this is like finding out you have a special discount card in your wallet as goods or services you often consume becomes cheaper.
So, the CPI is not just another economic statistic. This is a window, looking into our own purchasing power where it acts as a signal of how much one person’s hard-earned money can buy.
