July CPI expected 0.1% MoM, 3.4% YoY; JPMorgan outlines S&P moves ranging from +1% to –2% based on core CPI outcomes.

**LEDE**  
The U.S. July CPI is slated to rise 0.1% month‑over‑month, lifting the 12‑month headline rate to 3.4%, and JPMorgan says the S&P 500 could swing up to 2% depending on the core CPI print [2].

| At a glance | |
|---|---|
| July headline CPI MoM | 0.1% (consensus) |
| July core CPI MoM | 0.2% (consensus) |
| Fed‑rate hike odds | ~52% for a 25 bps hike (CME FedWatch) [2] |
| Potential S&P 500 move | +1% to +2% if core ≤0.15%; –1.5% to –2% if core ≥0.30% [2] |

## Market expectations and the CPI forecast  
The Bureau of Labor Statistics will release the July CPI at 8:30 a.m. ET on Wednesday. Forecasts call for a modest 0.1% rise in headline inflation, down from June’s 0.4% gain, and a 0.2% increase in core CPI, which would keep the annual core rate at 2.5% [1][2][3]. These numbers sit just above the prior month’s readings and match the consensus among Dow Jones economists [2]. The CME FedWatch tool currently prices a 52% chance that the Federal Reserve will raise its policy rate by 25 bps at the September meeting [2].

## JPMorgan’s scenario analysis for equities  
JPMorgan’s trading desk mapped out how the S&P 500 could respond to the core CPI outcome. If core CPI posts a month‑over‑month increase of 0.30% or higher (5% probability), the index could fall 1.5%‑2.5%. A core rise between 0.25%‑0.30% (25% probability) would likely drag the index down 0.5%‑1.25%. Conversely, a core CPI in the 0.20%‑0.25% band (40% probability) is expected to lift the S&P 500 by 0.25%‑0.75%, while a softer core reading of 0.15%‑0.20% (25% probability) could add 0.5%‑1%. The most bullish scenario—core CPI below 0.15% (5% probability)—would see the index rise 1%‑2% [2].

These ranges reflect the market’s sensitivity to “sticky” core inflation, which would reinforce expectations of a September rate hike, versus a softer core that could ease pressure on the Fed and buoy equities. The note also highlights that the U.S. has “dodged the proverbial bullet” from Middle‑East tensions, meaning oil‑price volatility may be a secondary driver of market moves [2].

## Currency and commodity backdrop  
A core CPI surprise to the upside could strengthen the dollar, putting bearish pressure on EUR/USD, especially if the pair tests the 1.1570 100‑day SMA resistance. Conversely, a softer core reading may weaken the greenback and allow the euro to test 1.1630‑1.1800 levels [1]. Oil prices, which rose roughly 22% in July after earlier declines, remain a wildcard; any sharp move could shift sentiment away from pure inflation metrics [1].

## What to watch  
- **September FOMC meeting (21 Oct)** – the Fed’s decision will hinge on whether July’s core CPI stays above or below the 0.20%‑0.25% range.  
- **Next CPI release (June 2025)** – a repeat of a modest rise would reinforce current market pricing; a larger jump could reset expectations.  
- **Key EUR/USD technical levels** – 1.1570 (100‑day SMA) and 1.1630 (200‑day SMA) as potential resistance, with 1.1515 acting as strong support [1].

The July CPI will be the litmus test for whether core inflation remains “sticky” enough to justify a September rate hike, a factor that could drive equity volatility and shape the dollar’s short‑term trajectory.
