September CPI Preview: Renewal of a softer trend
中文标题
9月CPI预览： softer trend 的重现
Core conclusion · Tlines extraction
Natixis expects September core CPI at 0.19% m/m and headline CPI at 0.6% m/m, both in line with consensus, reinforcing its view that underlying inflation keeps drifting lower. It sees little evidence of reacceleration: tariff and energy shocks are acyclical one-off drivers, inflation breadth has narrowed, and wage-driven core services ex-housing remain target-consistent. The Fed will treat incoming CPI data as its lodestar, so Natixis sees one more hike, likely the last of the cycle, with another possible in December or January.

Key arguments
- September core CPI is forecast at 0.19% m/m and headline CPI at 0.6% m/m, both in line with consensus.
- Inflation breadth narrowed before the second-half 2025 'Liberation Day' tariffs, and the Iran War energy shock added a further temporary supply-driven bump.
- The SF Fed's cyclical/acyclical split suggests one-off shocks, not monetary-policy-sensitive components, are keeping inflation elevated; core services ex-housing track wage growth consistent with target inflation.
- With the Fed calibrating its reaction function on incoming data, Natixis sees one more hike as its base case and that September may have been the lone hike of the cycle.
Key numbers

- 0.19%
- Headline CPI forecast, September (m/m)
- 0.6%
- Fed 2% inflation objective
- 2%
- Subcomponents running above 3% (Warsh citation)

- Market-implied odds of an October hike

Main risks
- August's disappointing CPI showed monthly inflation prints can be volatile even within an improving trend.
- Tariff and energy shocks are supply-driven and could keep inflation above the Fed's 2% target for longer.
- Influential Fed policymakers have signalled more hikes may be needed, and a December or January hike cannot be ruled out.

· 2026We forecast asubdued reading for core CPI, followed by similarly encouraging prints inthe next few months as well.
In response, we are anticipating just one more hike from the Fed that, when combined with relatively tighter financial conditions, will help nudge inflation lower.
