US May Core PCE Edges Down to 3.3%, Inflation Stickiness Continues to Test Fed's Patience
According to the latest data from DataTrack, the US core PCE (Personal Consumption Expenditures) price index for May 2026 recorded a year-over-year increase of 3.3%, edging down from 3.4% in April and ending the trend of consecutive monthly increases since the beginning of the year. Although the initial market consensus mostly landed at 3.4%, this data pullback partially reflects the impact of potential methodological revisions by the Bureau of Economic Analysis (BEA), and the overall figure remains well above the Federal Reserve's (Fed) 2% long-term target. This indicates that while US inflation pressure shows signs of marginal cooling, it has not yet fully dissipated.
Regarding key details, according to breakdowns by institutions like Babypips, the month-over-month growth rate of core PCE in May maintained a steady pace of approximately 0.3%. Services inflation continues to be the core driver supporting prices, while commodity prices present a mixed picture. Notably, VT Markets pointed out that the BEA's statistical adjustments on items such as portfolio management, legal services, and software provided roughly 15 basis points of downside revision room for the year-over-year core PCE rate. This is also one of the reasons why the given data dropped to 3.3%, which is milder than the external initial consensus.
In terms of deep attribution, market analysts generally believe that the "tariff effect" and "geopolitics" are the two major drivers of current inflation stickiness. Tensions in the Strait of Hormuz in the Middle East have not only driven up energy prices, but their associated transportation and production costs are also gradually passing through to core goods. In addition, the secondary pass-through effects of tariffs since the beginning of this year have not fully dissipated, offsetting some of the consumer demand suppressed by high interest rates, making the path of inflation retreat particularly bumpy.
Looking ahead at future risks and opportunities, in the short term (1-2 months), the market will highly focus on whether Middle East geopolitical developments will trigger a new wave of energy price shocks, thereby driving up the month-over-month increases of subsequent PCE data. In the medium term (3-6 months), given that core inflation still exhibits strong stickiness, investment banks have drastically compressed their expectations for Fed rate cuts this year from 3 times at the beginning of the year to 1-2 times, and even face the risk of delay. Investors should guard against the asset repricing risks brought by "Higher for Longer" interest rates and pay attention to potential short-term volatility in the fixed-income market.
