US July CPI came in at 3.4% year-over-year, in line with market expectations of 3.4%, and still well above the Federal Reserve's 2% inflation target.

The latest US CPI report delivered few surprises, with the key estimates all falling in line with consensus forecasts. Core annual inflation matched expectations, while headline annual inflation eased slightly, offering some added comfort to the Federal Reserve — at least for the time being.

With inflation data largely cooperative, the onus now falls on incoming economic data to justify a potential rate hike at the September Federal Open Market Committee (FOMC) meeting.

A continued escalation of the US-Iran conflict is widely seen as a prerequisite for pushing the Fed toward tightening. Without that geopolitical pressure, Fed Chair Warsh and the broader committee could more easily make the case to hold interest rates steady.

The Strait of Hormuz remains closed, a situation that continues to support elevated oil prices and apply pressure to the bond market. As one of the world's most critical oil shipping chokepoints — roughly a fifth of global petroleum liquids consumption transits the strait under normal conditions — its disruption carries significant implications for energy costs and inflation expectations. Rising yields remain a critical area to monitor, as unchecked increases could spill over into broader financial markets. In particular, a firm push in US 10-year yields above the 4.70% threshold could serve as a key catalyst for wider market disruption.

The relatively benign inflation figures, however, do not settle the debate over September policy. Market pricing has shifted toward the likelihood of no rate change, though the outcome is far from certain. Traders are currently pricing in approximately 35% odds of a rate hike, down from roughly a coin-flip probability before the CPI release.

Attention will now shift to the next major event on the calendar: the Jackson Hole symposium. The conference is scheduled for 27–29 August, with this year's theme set as "Financial Innovation: Implications for Payments and Policy."

The official agenda has not yet been released, but market participants will closely monitor Fed Chair Warsh's speech for any signals regarding a potential September move. However, given Warsh's push for a shift in the Fed's forward guidance stance, observers consider it unlikely that he will deliver any firm policy indications at the late-August gathering.

While markets will be focused on Jackson Hole, the more decisive factor for September expectations is likely to be the August US CPI report, scheduled for release on 11 September. That release falls just five days before the FOMC meeting and within the Fed's pre-meeting blackout period.

If the US-Iran conflict remains in its current state through that timeframe, markets are likely to continue pricing September policy outcomes within a narrow middle range, with conviction unlikely until the next inflation reading provides greater clarity.
