Inflation
US inflation softened in May; services inflation slowed, supercore near 2021 lows. Tariff risks loom, but disinflationary forces persist, keeping Fed in wait-and-see mode.
US inflation data for May surprised to the downside, with both headline and core CPI rising just 0.1% month-on-month, below consensus forecasts of 0.2% and 0.3% respectively. On an annual basis, headline CPI remained at 2.4% YoY, in line with expectations, while core CPI eased slightly to 2.8% YoY, just below the 2.9% forecast. The core “supercore” measure — core services excluding housing — rose slightly to 2.86% YoY in May, though it remains near its lowest levels since 2021, reflecting a continued moderation in underlying services inflation. On a year-over-year basis, service sector cost pressures are decelerating, while goods prices are stabilising or increasing only very modestly. Key categories such as apparel (-0.4% MoM), new vehicles (-0.3% MoM), and airline fares (down for a fourth consecutive month) helped restrain price pressures, while shelter inflation remained moderate at 0.3% MoM. Despite the benign May data, risks remain on the horizon: the Fed’s Beige Book notes many businesses plan to pass on higher input costs — largely tariff-related — within the next few months, which could push headline CPI closer to 4% YoY by Q3. However, these tariff-driven increases are expected to be transitory and will gradually roll off the annual comparisons by late summer 2026. Meanwhile, disinflationary forces persist, with indicators such as the Cleveland Fed’s new tenant rent index pointing to further softening in shelter inflation, and a cooling labour market potentially helping to contain wage-driven service inflation. Against this backdrop, the Federal Reserve is likely to remain in a data-dependent wait-and-see mode as it assesses both near-term upside risks and the underlying disinflationary trends in the broader economy.
We expect inflation to rise modestly short term due to tariffs, but disinflationary trends in services, housing, and labour will likely keep the Fed cautious and data-dependent.
