September CPI preview: Inflation seen holding firm near 3% as tariffs complicate Fed's path

The delayed September Consumer Price Index (CPI) is projected to show headline and core inflation both at 3.1% year-over-year, reflecting persistent price pressures. Analysts attribute this stickiness primarily to ongoing tariff impacts on goods, which are expected to continue boosting inflation into 2026, and stubbornly high non-housing services costs, particularly in medical care and transportation. While some anticipate a slight downside risk for the September figure from softer shelter costs, the overall outlook suggests inflation remains elevated, complicating the Federal Reserve's efforts to reach its 2% target.

Analysis

September's Consumer Price Index (CPI) is projected to show headline and core inflation both at 3.1% year-over-year, marking the highest headline rate since May and exceeding the 12-month average of 2.7%. This persistent elevation, significantly above the Federal Reserve's 2% target, underscores ongoing inflationary pressures. The delayed release due to the government shutdown highlights potential data volatility and broader economic uncertainty.

Analysts from Bank of America and Goldman Sachs identify tariffs as a primary driver, expecting them to boost goods price inflation into Q1 2026, with companies anticipated to increase pass-through to consumers by Q3/Q4 2025. Concurrently, sticky non-housing services inflation, particularly in medical care and transportation, remains "too firm for comfort," according to Steven Juneau. These factors collectively complicate the disinflationary path.

While the consensus points to elevated inflation, BNP Paribas notes "downside risks" for the September CPI, citing softer shelter costs and only modest tariff pass-through in goods. However, BNP also anticipates "more material pass-through" of tariffs into Q1 2026, suggesting that any near-term moderation might be temporary. This divergence highlights uncertainty regarding the timing and magnitude of tariff impacts.

Key Decisions for Investors

• Investors should anticipate the Federal Reserve maintaining a hawkish stance or delaying rate cuts longer than previously expected, impacting interest-rate sensitive assets, given persistent inflation expectations.
• Monitor companies with significant exposure to import tariffs and assess their ability to pass through costs, as increased consumer burden is projected by Q1 2026, potentially affecting consumer discretionary spending.
• Consider inflation-hedging strategies or investments in sectors less sensitive to goods price fluctuations but potentially benefiting from sticky services inflation, such as healthcare or transportation.
