Wholesale Inflation Hits Highest Level Since 2022 in May

Wholesale prices rose 1.1% in May, exceeding economist expectations of a 0.7% gain and matching the increase seen in April [1, 2]. The Bureau of Labor Statistics reported that this surge pushed the 12-month wholesale inflation rate to 6.5%, the highest level recorded since November 2022 [1, 2].

Key takeaways

• Energy prices accounted for 80% of the rise in final demand goods, led by a 23.4% jump in wholesale gasoline costs [1, 2].
• The core PPI, which excludes food and energy, rose 0.4% in May, coming in slightly below the 0.5% increase expected by analysts [1, 2].
• A measure excluding food, energy, and trade services saw its largest monthly gain since March 2022, rising 0.8% [1, 2].
• Portfolio management fees contributed to service-side inflation, rising 4.8% as the stock market reached record highs [1, 2].

Energy costs drive inflationary pressure

The sharp increase in wholesale prices is largely attributed to the ongoing conflict in Iran, which has disrupted energy supplies and led to a blockade in the Strait of Hormuz [1, 2]. According to the Bureau of Labor Statistics, final demand goods prices surged 2.8%, the largest increase in a data series dating back to December 2009 [2]. Beyond gasoline, the price of diesel, jet fuel, natural gas liquids, and industrial chemicals also saw significant jumps, creating a ripple effect that has increased costs for apparel, food, and air travel [1].

While the headline numbers remain elevated, some underlying metrics show a more nuanced picture. The core PPI, which strips out volatile food and energy costs, rose 0.4% [1]. However, when trade services are also excluded, the index rose 0.8%, marking its highest monthly gain since March 2022 [2]. Analysts suggest that while the current spike is likely temporary and tied to the war, there is growing concern that the conflict could persist, keeping oil prices and inflation elevated for an extended period [1].

Why it matters

The latest inflation data has complicated the outlook for the Federal Reserve, which is scheduled to meet next week to discuss interest rates. While market participants overwhelmingly expect the Fed to keep rates steady at the upcoming meeting, the probability of a rate hike at the July meeting has risen above 12% according to some estimates, while other market pricing suggests a potential hike as late as December [1, 2].

Federal Reserve officials have generally advocated for a patient approach to determine if the current energy-related price shock will subside on its own [2]. In contrast, the European Central Bank has already taken action, raising its benchmark interest rate to 2.25% in response to the global inflation surge [1, 2]. Meanwhile, domestic political discourse remains focused on the impact of these figures, with President Trump noting that he expects current inflation rates to represent the peak of the price surge [1].
