How Trade Policies and Inflation Shape the S&P 500

The U.S. economy is navigating a complex landscape. Inflation continues its gradual descent toward the Federal Reserve’s 2% target, while the labor market shows signs of cooling yet remains relatively resilient. February 2025 data reveal significant economic shifts, with the annual inflation rate falling to 2.8% and the unemployment rate rising to 4.1%.

As you can see from the S&P 500 chart, the index is now testing local support at 5,500-5,700 points. But let’s take a closer look at the market dynamics, particularly within the equity space, to identify key points for the analysis at a pivotal juncture — on the brink of either a recovery or the confirmation of a new bear market.

Recent inflation figures present an overall positive picture, with a steady decline, albeit at a pace slower than analysts had hoped. According to the Bureau of Labor Statistics, the U.S. annual inflation rate decreased to 2.8% in February 2025, down from 3% in January and beneath market expectations of 2.9%. On a monthly basis, consumer prices increased by 0.2% in February, a notable deceleration compared to January’s 0.5% rise and below the anticipated 0.3%. This cooling trend provides encouraging evidence that inflationary pressures are gradually abating.

On the labor market front, the U.S. economy added 151,000 nonfarm jobs in February 2025 — slightly below market expectations of 160,000 units. However, several sectors, notably healthcare and personal care services, experienced job losses, indicating uneven economic growth. The national unemployment rate climbed to 4.1% in February from 4.0% in January. While this marginal increase still reflects historically low levels—consistent with many economists’ definition of full employment — the upward trend warrants close attention, especially given that unemployment has been rising steadily from the post-pandemic lows of approximately 3.7% (currently not triggering the Sahm Rule).

In its March 2025 meeting, the Federal Open Market Committee (FOMC) maintained the federal funds rate in the range of 4.25%-4.5%, extending the pause in rate cuts initiated in January 2025. This decision aligned with market expectations and underscored the Fed’s cautious approach amid persistent inflation concerns and growing economic uncertainty. Currently, the market anticipates two rate cuts of approximately 50 basis points each later this year—likely in June and December—should economic data continue to evolve as projected.

Trade and Tariff Effects

Several economic forecasts now incorporate the expected impact of new tariffs on inflation. The Personal Consumption Expenditures (PCE) inflation rate is projected to rise to 2.4% in Q3-Q4 2025 “due to the new tariffs,” before retreating to lower levels in 2026. This suggests that the Trump administration’s trade policies are likely to exert upward pressure on inflation in the short term.

Not all government policies are expected to have inflationary effects. Deregulation and increased energy production are bolstering business optimism. These supply-side measures could help mitigate some inflationary pressures by enhancing productive capacity and reducing energy costs, though their impact may take longer to materialize compared to the more immediate effects of the tariffs.

The combination of moderate growth, persistent inflation, and significant political uncertainty is creating conditions for increased market volatility. Atlanta Fed President Bostic has explicitly highlighted the “significant economic volatility” stemming from multiple sources of uncertainty, including tariffs, trade policy, the impact of immigration policy on the workforce, energy policy, fiscal reforms, federal spending, and geopolitical tensions.

In this environment, risk premiums could rise across all asset classes, and markets may become more sensitive to economic data, particularly regarding inflation and employment. For instance, the Consumer Price Index (CPI) released on March 12, 2025, registering 3.5% year-over-year against a forecast of 3.2%, triggered a 2.31% drop in S&P 500 futures within 30 minutes — from 5,200 to 5,080. Negative moves in assets like Bitcoin (-4.62%) and Ethereum (-4.29%) further reflect the heightened sensitivity of risk assets to inflation readings that exceed expectations. Market participants remain acutely focused on the timing of interest rate cuts, with swap markets pricing in complete cuts by July 2025 following December’s softer CPI data.

A positive signal for equity markets is the continued growth in EBITDA for the S&P 500, with a price-to-earnings ratio of 22 supported by a rebound in corporate earnings.

Conclusion

The trajectory of the S&P 500 hinges on three key factors:

  • CPI Trajectory: An uptick in PCE inflation in Q3 2025 driven by tariffs could trigger a significant market downturn.
               
  • Fed Guidance: Markets are pricing in a 50 basis point cut; any deviation from this expectation could substantially increase volatility.
               
  • Earnings Performance: Analysts project the index could reach 6,500 by year-end (a 14% increase) if earnings grow in line with forecasts of 8-10%.

At present, the S&P 500 is operating in a “sweet spot” with respect to volatility, balancing moderate economic growth against political risks arising from the Trump administration’s trade policies. Investors should brace for fluctuations surrounding CPI/Fed meetings while favoring sectors characterized by earnings visibility and quality.
