Inflation Takes a Breather: US Sees Lowest Annual Rate in Over Two Years

The inflation rate in the United States receded in May to its lowest annual rate in over two years, as per a report from the Labor Department. The consumer price index (CPI), a key measure of changes in the prices of various goods and services, increased by a mere 0.1% for the month. This deceleration brought the annual inflation rate down to 4% from 4.9% in April, marking the smallest 12-month increase since March 2021.

But what exactly is inflation? In simple terms, inflation is the rate at which the general level of prices for goods and services is rising, and subsequently, purchasing power is falling. Central banks attempt to limit inflation — and avoid deflation — in order to keep the economy running smoothly. Although moderate inflation is normal in a growing economy, high inflation can erode purchasing power and can harm the economy. Conversely, deflation can also be harmful, as it encourages consumers to delay purchases in anticipation of further price drops, which can lead to a slowdown in economic growth.

Interestingly, when we exclude the notoriously unpredictable food and energy prices, we see a different figure known as core inflation. Core inflation in May rose 0.4% on the month and was still up 5.3% from a year ago. This suggests that, although the general price pressures have somewhat eased, consumers are still feeling the impact.

Core inflation is a measure of inflation that excludes certain items that face volatile price movements because it’s believed the volatility can distort the overall view of inflation. These excluded items, typically food and energy commodities, are known to have prices that can be quite variable, influenced by factors such as weather, natural disasters, or international events.

This case study provides a real-world example of how inflation rates can oscillate and the repercussions these changes can have on consumers and the wider economy. It also underscores the role of the Federal Reserve in managing inflation through adjustments to the interest rate. By manipulating interest rates, the Federal Reserve can control money supply in the economy, which, in turn, influences the rate of inflation: a lower interest rate increases the supply of money, which can potentially lead to increased inflation, while a higher interest rate can slow the economy and reduce inflation. Understanding these fundamental economic concepts is crucial for interpreting the financial world around us and making informed decisions.
