- The latest data from the U.S. Bureau of Labor Statistics (BLS) shows that the Producer Price Index (PPI) for final demand rose by 0.5% month-on-month in March, lower than the previous market expectation of 1.1%; however, the year-on-year increase reached 4.0%, marking the largest single-month year-on-year increase since February 2023.
- The sharp rise in energy commodity prices was the core driver pushing up the PPI. Affected by geopolitical wars in the Middle East and maritime blockades, gasoline prices rose by 15.7% month-on-month, and jet fuel costs surged by 30.7%, propelling the overall energy category to continue a large increase of 8.5% in March after increasing by 2.1% in February.
- After excluding food and energy, which are volatile items, market institutions expect the March Core Personal Consumption Expenditures (PCE) Price Index to rise by 0.3% month-on-month and 3.2% year-on-year. As the stickiness of inflation transmission upstream becomes evident, the financial market's pricing of the probability of the Federal Reserve (Fed) cutting interest rates within the year has dropped to about one-third, with the overnight benchmark interest rate maintained in the range of 3.50% to 3.75%.
Supply-side Shock and Commodity Price Reassessment
The substantive escalation of geopolitical conflicts in the Middle East is profoundly reshaping the industrial ex-factory price system in the United States. Since the outbreak of conflict at the end of February, international crude oil prices have cumulatively risen by over 35%, recently breaking through the psychological barrier of $100 per barrel. This extreme geopolitical risk premium is directly reflected in the commodity price sub-index of the Bureau of Labor Statistics. In March, the overall commodity cost rose by 1.6%, significantly higher than the previous value of 1.0%. The 14.4% increase in liquefied natural gas prices and the jump in refined oil indicate that input costs are being re-priced in the energy and chemical primary industries at an unprecedented speed. If maritime blockades persist, the risk exposure of the energy supply chain may further expand.
Service Industry Inflation Divergence and Tariff Pass-Through Effect
Compared with the violent fluctuations in goods, service industry prices in March exhibited complex structural characteristics. Overall service prices remained flat for the month, cooling from a 0.3% increase in February. Among these, trade service profit margins fell by 0.3%, partially offsetting the 1.3% cost increase in transportation and warehousing services. Macroeconomists pointed out that this temporary stability in service prices may suggest that the pass-through effect of early tariff policies has reached its end. However, sub-sections such as wholesale airline prices rebounded by 2.8% after previous declines, and portfolio management fees rose for a second consecutive month by 1.0%, indicating that service sectors with strong pricing power are still passing on high operational costs to downstream consumers.
Hawkish Adjustment of Monetary Policy Path
The structural strength of the PPI data further solidifies the Federal Reserve's macro logic of maintaining tight monetary policy. Given that PPI subsections like airfares, healthcare, and portfolio management are directly linked to the calculation weights of the PCE price index, persistently high upstream prices have made the path to returning the terminal inflation target to 2% exceedingly narrow. The minutes of the central bank's March monetary policy meeting released last week have shown hints, with some policymakers even beginning to discuss the possibility of restarting the rate hike cycle. If subsequent CPI and PCE data continue to confirm the trend of a second inflation rebound, the timing of the Fed's substantial easing within the year may face a comprehensive re-evaluation, which could further raise the risk-free yield center of short-term government bonds.
