July CPI Print Preview: A Tale of Upside Risk
Published August 10, 2026
Download PDF- Market forecasts rest just under consensus. Kalshi market-implied CPI forecasts have converged to 3.3% Headline YoY / 2.4% Core YoY, sitting narrowly below external estimates with the Cleveland Fed Nowcast and consensus projections of 3.4%/2.5% YoY.
- It’s an Iran story. Kalshi market-implied distribution skews to the upside, reflecting an uncertainty around the resolution of conflict in the Middle East and significant disruption to shipping channels likely to hit Core CPI through supply chains.
- Market divergence is worth watching. Over a three-year look-back window, Kalshi markets display lower error relative to consensus estimates at points of divergence from expectations, indicating differentiated expectations that validate its use as a corroborating tool.
July CPI is due Wednesday morning against a softening backdrop: June’s downside surprise, followed by a weaker-than-expected July employment report (nonfarm payrolls -23,000 vs. consensus +83,000). Kalshi’s market-implied estimates sit a tick below both the Cleveland Fed Nowcast and consensus, at 3.3% headline and 2.4% core CPI, respectively, on a year-over-year basis. The implied distribution remains skewed to the upside, driven by two factors: (1) gasoline prices, contingent on the resolution of the Middle East conflict, and (2) tariff- and Hormuz-related freight costs, which continue to build within core.

It's an Iran Story
Transportation accounts for the entirety of the 2026 acceleration: a modest drag through most of 2025, it is now by far the largest single driver of the move higher. Weighting gasoline’s 2.9% CPI share by its own year-over-year swing, from -7.5% in January to a roughly 40% peak in May, explains approximately three quarters of the total increase in headline CPI over that period.


Eyes now turn to the potential for resolution and/or escalation in the region. A ceasefire announced in early April briefly calmed prices before fighting resumed in July, and as of early August, Iran and Oman are still negotiating whether shipping through the Strait reopens. Kalshi’s confidence bands reflect that uncertainty, skewing to the upside heading into the fall.
Airfare shares gasoline’s root cause and adds a second, distinct channel. Jet fuel is also a crude derivative, and its price move has been comparably sharp: the global average rose from roughly $2.50 a gallon before the conflict to $3.93 within days, with IATA’s fuel monitor showing an additional 18% week-over-week increase in mid July as fighting re-escalated, pushing fuel’s share of airline operating costs from roughly a quarter to nearly a third.
The Iran conflict’s reach into core inflation extends well beyond the pump. The Strait of Hormuz carries roughly a fifth of the world’s oil and liquefied natural gas, and its closure since late February, combined with renewed Red Sea disruption, has forced container and tanker traffic to reroute around the Cape of Good Hope, pushing freight rates higher even on routes with no direct Middle East exposure. Asia to US ocean rates were still up 29% in April. Layered on top of tariffs, which researchers at the Dallas Fed estimate have added close to 0.8 percentage points to core inflation on their own, that freight shock moves through a similar seven-month pass-through window, meaning costs from the worst of the closure are still reaching shelves now. The Gulf is also a major exporter of fertilizer inputs, so a prolonged disruption may also represent a slower-moving risk to food prices.
A Fed That Says Less, Even As Inflation Says More
Mentions of “inflation” during FOMC press conferences have fallen from a peak of 78 at the December meeting to just 40 at the July 29 press conference, even as the underlying data has, if anything, become louder, and the Committee more worried. This is undoubtedly a reflection of Chair Warsh’s explicit preference for shorter statements and less forward guidance. The July decision itself, a 9-3 hold, with Cleveland’s Hammack, Minneapolis’ Kashkari, and Dallas’ Logan all dissenting in favour of a hike, marked the most regional-president dissents in a single direction since September 2016. If this print comes in above expectations, it would all-but-guarantee a hike at the next FOMC meeting in September.

Kalshi Markets Outperform Consensus Inflation Estimates
Why do Kalshi inflation estimates matter?
Across 36 one-week-ahead observations, Kalshi’s median forecast error on headline CPI (YoY) comes in at 6.7bp against an 8.9bp consensus error (mean: 7.3bp), a gap corroborated independently by the Federal Reserve’s own research staff, whose February 2026 FEDS paper (Diercks, Katz, and Wright) found Kalshi’s headline CPI (YoY) expectations to be a statistically significant improvement over the Bloomberg consensus. This implies that market traders are trading on differentiated knowledge and may offer value to moderate and/or corroborate views in times of uncertainty.

Zooming Out: The Global Inflation Picture
Inflation across developed markets, which had converged into a fairly tight 2 to 4% band by 2024, is now ticking up in near lockstep. The US, UK, Canada, and Australia have all moved higher since late 2025, clustering around 3 to 4%. Notably, Japan, which has run persistently below the rest of the group for years, is showing the same upward inflection, climbing back toward 2%. The synchronicity is the key point: the global energy crisis emanating from the Middle East is clearly affecting all regions of the world, and all eyes are on the Fed’s path back to 2%.

Conclusion
The single most significant current determinant of inflation, and thus Fed decisions, is what happens in Iran – both through direct impact on crude oil pricing and supply chain disruption likely to filter through to goods inflation. Reignited tensions deriving from recent failures in negotiation have skewed future estimates upward, implying the potential for stickier inflation that would force the hand of the FOMC when it next meets in September.
