The May inflation report came in exactly where many expected, yet the details beneath the headline reveal what is actually taking place in the economy. Consumer prices rose 0.5% for the month and 4.2% year-over-year, the highest inflation reading in three years. Core inflation, which excludes food and energy, rose only 0.2% for the month and 2.9% annually. This is primarily an energy shock that is spreading through transportation, travel, and production costs due to the war in Iran.
Government data show that energy alone accounted for more than 60% of the monthly increase in consumer prices. Energy prices rose 3.9% in May after climbing 3.8% in April. Gasoline prices surged 7.0% in a single month and are now up 40.5% compared to a year ago. Electricity prices rose 5.9% over the past year while natural gas prices increased 3.0%. These are not insignificant numbers. Energy is the foundation of every economy. Every product must be manufactured and transported. Every store must be heated, cooled, and illuminated. When energy rises, it eventually works its way into virtually every aspect of economic activity.
What is particularly important is that shelter inflation remains elevated. Shelter costs rose another 0.3% in May and are up 3.4% over the past year. Rent increased 0.4% for the month while owners’ equivalent rent rose 0.3%. Housing remains one of the largest expenses for the average household, and these increases continue to erode disposable income even as policymakers insist inflation is under control.
Food prices are also moving higher, though at a slower pace than energy. The overall food index rose 0.2% during May and 3.1% over the past year. Food away from home increased 3.5% annually, showing that restaurants continue passing higher operating costs on to consumers. Fruits and vegetables are up 6.1% over the past year while beverages increased 5.8%. The average family notices these increases every week at the grocery store regardless of what economists may say about “core inflation.”
Transportation is beginning to show the impact of rising fuel costs. Airline fares jumped 2.7% in May alone and continue to rise as carriers pass along higher jet fuel expenses. The travel sector has been particularly vulnerable because energy prices affect everything from airline tickets to hotel operations and rental cars. We are seeing the same pattern that has repeated throughout history whenever geopolitical tensions disrupt energy supplies.
The political establishment will attempt to debate whether inflation is temporary or permanent. They always focus on labels instead of causes. The numbers show that this inflation surge is being driven primarily by energy. Whenever governments become involved in war or geopolitical confrontation, energy becomes the transmission mechanism that spreads economic pain throughout the system. The current Middle East conflict has once again demonstrated how fragile global supply chains remain and how dependent modern economies are on stable energy markets.
The May CPI report demonstrates that inflation has not disappeared. It merely changed form. The energy sector is once again dictating economic reality. As we move deeper into a Panic Cycle year, geopolitical events are becoming increasingly important drivers of economic activity. The lesson remains the same as it has throughout history: when energy prices move sharply higher, they eventually impact everything else.
