As inflation remains a persistent concern, the Federal Reserve's next move has become a focal point for global markets. If inflation is a tug-of-war with economic growth, the unexpected decline in March's U.S. Consumer Price Index (CPI) has given the "growth" side a much-needed breather. Does this data signal that the Fed will resume its rate-cutting path in June to inject new vitality into the economy?

1. March CPI Overview: A Notable Drop, Exceeding Expectations

Data released by the U.S. Bureau of Labor Statistics (BLS) showed that the CPI rose 2.4% year-over-year in March 2024—lower than the market consensus of 2.5% and February's 2.8%. More strikingly, the monthly CPI declined by 0.1%, marking the first negative growth in nearly five years and falling well below expectations of a 0.1% increase and February's 0.2% rise. These figures suggest a significant easing of inflationary pressures in March.

2. Core CPI: Also Shows a Downward Trend

Excluding volatile food and energy prices, core CPI—which better reflects underlying inflation—rose 2.8% year-over-year in March, hitting a nearly four-year low. This was below both the market forecast of 3.0% and February's 3.1%. The monthly increase in core CPI slowed to 0.1%, the smallest gain in nine months, and below expectations of 0.3% and February's 0.2%. The downward trend in core CPI further supports the view that inflation is cooling.

3. Supercore CPI: Growth Slows to Multi-Year Low

Supercore CPI (excluding housing), which better reflects service-sector inflation, saw its annual growth rate drop to 3.2% in March—the lowest since December 2021—while monthly growth fell by 0.1%. This indicates that service-sector inflation is also beginning to ease, a positive signal for the Fed.

4. Housing and Rent: Key Inflation Drivers Show Signs of Cooling

Housing and rent costs have been major contributors to U.S. inflation in recent years. In March, housing inflation rose 0.3% month-over-month and 3.99% year-over-year—the latter marking the slowest pace since November 2021. Rent inflation followed a similar pattern, increasing 0.3% monthly and 3.99% annually, down from February's 4.09% and the lowest since January 2022. The notable slowdown in housing and rent inflation helps alleviate overall price pressures.

5. Factors Behind the CPI Decline: A Combination of Drivers

The unexpected drop in March's CPI resulted from multiple factors:

  • Energy prices fell: Fluctuations in global oil prices directly impacted energy costs, contributing to the CPI decline.
  • Used car prices dropped: After a prolonged surge, used car prices began to retreat as supply chain issues eased and new vehicle availability improved.
  • Airfare declined: Seasonal travel patterns led to lower ticket prices in March.
  • Apparel prices grew slowly: Weakness in clothing prices also weighed on overall inflation.

6. Tariff Policies: A Potential Inflation Risk

Despite March's encouraging CPI data, future inflation risks remain. Former President Donald Trump has proposed expansive tariff policies that could reintroduce price pressures. Key measures include:

  • A 10% tariff on imports from multiple countries, raising costs for consumers.
  • Additional tariffs on steel and aluminum imports, increasing production expenses.
  • Higher tariffs on Chinese goods, potentially escalating trade tensions.

Companies such as Target and Volkswagen have already warned of impending price hikes. Fed officials are closely monitoring how tariffs may affect inflation and the broader economy.

7. Market Reaction: Rate Cut Expectations Rise

Following the CPI release, traders increased bets on Fed rate cuts, pricing in a 67% chance of a 25-basis-point reduction in June. Some now expect a full percentage point (100 basis points) of cuts by year-end. Earlier expectations had centered on 75 basis points of easing in 2024.

This shift pushed Treasury yields lower and extended the dollar's decline.

8. The Fed's Focus: PCE Inflation and Policy Outlook

Fed officials emphasize core Personal Consumption Expenditures (PCE) inflation as their preferred gauge, which is now trending toward the 2% target. March's Producer Price Index (PPI) will offer further clues about PCE trends and the Fed's next steps.

According to CME's FedWatch tool, markets currently assign a 67% probability to a June rate cut, with a 16.5% chance of no change or a 50-basis-point reduction. For May, an 80% likelihood favors unchanged rates.

9. Rate Cut Probabilities: July and September Outlook

Markets also see elevated odds of cuts in July (56%) and September (45%), with a 33.8% chance of another move in December. This reflects expectations that the Fed will continue easing in the second half of 2024 to balance inflation risks against growth concerns.

10. Conclusion: Rate Cuts Likely, but Caution Persists

March's softer inflation data has opened the door for Fed rate cuts, reshaping market expectations. However, uncertainties—particularly around tariffs—warrant vigilance. The Fed must weigh multiple factors to achieve its dual mandate of price stability and maximum employment. Investors should stay attuned to upcoming economic releases and policy signals to navigate potential risks and opportunities.

  • Supercore CPI: Further excludes housing costs to assess service-sector inflation.
  • Personal Consumption Expenditures (PCE) Index: The Fed's preferred inflation measure, reflecting actual consumer spending.
  • Producer Price Index (PPI): Tracks input costs for producers, often a leading indicator for CPI.
