Key Points The seasonally adjusted US Consumer Price Index (CPI) increased 0.6% month-over-month in April, with the year-over-year rate rising to 3.8%, the highest level since May 2023. Excluding food and energy, the core CPI rose 0.4% month-over-month and 2.8% year-over-year, indicating inflation remains well above the Federal Reserve's 2% policy target. While energy prices, particularly gasoline, were a primary driver of higher inflation, price pressures have now spread to numerous other sectors. The data also presents a negative outlook for workers: real average hourly earnings declined 0.5% month-over-month and fell 0.3% year-over-year. The stronger-than-expected increase in prices for a broad range of goods and services in April has intensified market concerns about inflation's impact on the US economy.

The US Bureau of Labor Statistics reported Tuesday that the CPI rose 0.6% on a seasonally adjusted monthly basis, with the annual rate climbing to 3.8%. The monthly figure matched market expectations, while the annual rate was 0.1 percentage point higher than the Dow Jones consensus estimate. Core CPI, which excludes food and energy, increased 0.4% month-over-month and 2.8% year-over-year, remaining significantly above the Federal Reserve's 2% target. Fed officials view core inflation as a better indicator of long-term price trends. The headline annual inflation rate reached its highest point since May 2023, accelerating by 0.5 percentage points from March. The core annual inflation rate also increased by 0.2 percentage points.

Energy prices surged 3.8% for the month, re-emerging as a primary contributor to rising inflation. Food prices also increased 0.5% month-over-month. Over the past 12 months, energy prices have risen 17.9%, while food prices are up 3.2%. Gasoline prices have soared 28.4% year-over-year. Although energy, and specifically gasoline, has captured market attention, inflationary pressures have broadened across multiple other categories. Housing costs, which had shown signs of moderating in prior months, rose 0.6% month-over-month in April, suggesting the inflation problem extends beyond the impacts of the situation involving Iran. Apparel prices, significantly affected by tariffs, rose 0.6% month-over-month. Airline fares jumped 2.8% for the month and are up a substantial 20.7% year-over-year. Tariff impacts were also felt elsewhere, with prices for household furnishings and operations increasing 0.7% month-over-month.

This inflation report carried negative implications for wage earners: real average hourly earnings decreased 0.5% month-over-month and declined 0.3% year-over-year. Following the data release, US stock index futures turned lower, while Treasury yields moved higher. Data from the CME Group Inc indicated traders increased the implied probability of a Federal Reserve rate hike this year to approximately 30%. Heather Long, Chief Economist at Navy Federal Credit Union, stated, "Inflation is now the primary drag on the US economy, tangibly harming people's lives and significantly increasing financial pressure on households. For the first time in three years, inflation has completely eroded wage gains, and middle- and low-income families are clearly feeling the impact."

The latest inflation data arrives as the Federal Reserve stands at a policy crossroads. The Fed has held its benchmark interest rate steady this year, with policymakers displaying clear divisions over the future path of rates and the communication of policy. At the end of April, the Fed once again voted to hold rates steady, but the decision saw four dissenting votes, the highest number since 1992. Fed Governor Stephen Milan again advocated for a 25 basis point rate cut. Three regional Fed bank presidents objected to the policy statement's wording, which markets had interpreted as signaling a bias toward future rate cuts. Meanwhile, incoming Fed Chair Kevin Warsh has advocated for rate cuts, but the resurgence of inflation following the outbreak of conflict involving Iran has made his dovish stance difficult to justify. Data from the American Automobile Association (AAA) shows energy prices have surged dramatically, with oil prices surpassing $100 per barrel and the national average gasoline price rising to $4.50 per gallon. Chris Zaccarelli, Chief Investment Officer at Northlight Asset Management, commented, "Given the renewed deterioration in inflation trends and the continued resilience of the labor market, a Fed rate cut in the near term is almost impossible. The market may even begin pricing in expectations for a rate hike next year."

Amid the high-interest-rate environment, consumer confidence has fallen to historically low levels, yet US stock markets have shown remarkable resilience. Major US stock indices are within striking distance of their all-time highs, and the current strong corporate earnings season is drawing to a close. Consumer spending has remained robust, but this strength is primarily supported by higher-income groups and is also being inflated by the overall rise in price levels.
