US May PCE inflation keeps Fed hike in play

The Personal Consumption Expenditures price index, a key measure of U.S. inflation, rose 4.1% year over year in May. On a monthly basis, the index increased 0.4%. These readings marked a firm pace of price gains and underscored that inflation pressures have not yet receded to levels consistent with the Federal Reserve’s 2% target.

Core PCE, which excludes the more volatile food and energy categories, advanced 3.4% compared with a year earlier. Month over month, core prices rose 0.3%. The core measure is closely watched as an indicator of underlying inflation trends, and its May performance pointed to persistent, though not accelerating, price pressures.

Alongside elevated inflation, the May data showed solid household nominal income and outlays. Personal income increased 0.7% during the month, matching a 0.7% rise in personal consumption expenditures. These figures indicated that consumers continued to see income growth and sustained their spending despite higher prices.

The combination of rising incomes and steady spending suggests that demand in the economy remained resilient. That resilience can support ongoing economic activity but also has the potential to make it harder for inflation to slow quickly if strong demand persists against constrained supply in some sectors.

Market commentary following the release of the May PCE data highlighted its implications for U.S. monetary policy. With both headline and core inflation running above the Federal Reserve’s stated objective, investors assessed that the prospect of additional interest rate increases remained in play.

Traders assigned a significant probability to a further rate hike later in the year, with some focusing on the potential for action around September. The persistence of elevated inflation, set against ongoing income and spending growth, reinforced expectations that the central bank may need to keep policy tight, or potentially tighten further, to bring inflation closer to target.
