July CPI, PPI data to test Fed's 57% September hike odds

Markets price a 57 percent probability of a September Fed hike from the current 3.50-3.75 percent range, with July CPI due Wednesday set to determine whether Chair Kevin Warsh's conditional readiness to tighten becomes reality.

"We're reading this as a committee with vocal hawks, but the majority is siding with Warsh to keep rates stable until at least September, when policymakers will have the benefit of the July and August CPI reports," Ian Lyngen, head of US rates at BMO Capital Markets, said after the July 29 decision.

Economists expect July headline CPI to slow to 3.4 percent from 3.5 percent in June, with core inflation easing to 2.5 percent from 2.6 percent, according to consensus estimates. The Cleveland Fed's nowcast model projects 3.42 percent headline and 2.52 percent core. The June PCE report — the Fed's preferred gauge — showed 3.7 percent headline and 3.3 percent core inflation.

A hotter-than-expected print would strengthen the case for the three dissenting hawks — Cleveland's Beth Hammack, Minneapolis's Neel Kashkari, and Dallas's Lorie Logan — who voted against the July 29 hold, the fifth consecutive pause. Bank of America forecasts three consecutive 25-basis-point hikes in September, October, and December, lifting the fed funds rate to 4.25 percent to 4.50 percent by year-end.

The stakes extend beyond the CPI release. July producer prices arrive Thursday, offering an early read on cost pressures before they reach consumers, while Friday's retail sales report gauges the health of consumption — the main engine of the US economy. A strong retail sales figure would show households holding up despite elevated borrowing costs, a positive signal for the earnings outlook of the retail sector.

The data follows a July jobs report that complicated the Fed's calculus. Nonfarm payrolls fell by 23,000 in July, with May growth revised down to 63,000 from 129,000 and June cut to 20,000 from 57,000 — a combined downward revision of 103,000. The unemployment rate ticked lower to 4.1 percent, but the labor force participation rate dropped to 61.4 percent, the lowest in more than five years, as workers stopped looking for jobs. Average hourly earnings grew just two cents, with annual wage growth easing to 3.2 percent.

The weak labor data trimmed September hike odds from 55 percent to 44 percent immediately after the report, before Warsh's conditional signal and Governor Lisa Cook's hawkish remarks pushed them back to 56.7 percent. Two-year Treasury yields have settled near 4.20 percent, while the 10-year yield trades around 4.64 percent.

Three Inflation Engines

The inflation problem facing the Fed has three separate drivers, each difficult to resolve quickly. Energy remains the most volatile: Brent crude closed Friday at $85.29 per barrel, still elevated after Iran's closure of the Strait of Hormuz in February pushed prices briefly above $100. The Dallas Fed estimates that even a one-quarter Hormuz closure would raise US headline inflation by 0.6 percentage points in 2026.

Tariffs represent a second channel. Cook's May speech laid out the mechanism: tariffs create a one-time price-level shift, but if firms embed that shift into longer-run pricing decisions, the effect persists. The third driver is AI infrastructure investment, projected to exceed $700 billion in 2026. The Dallas Fed estimates data-center electricity demand could raise annual PCE inflation by 0.04 to 0.13 percentage points per year through 2030.

What's at Stake for Markets

The S&P 500 has notched roughly 25 record highs in 2026 and is up 13.7 percent year to date, with the Dow crossing 54,000. Q2 earnings are on pace to grow 29 percent year over year, and about two-thirds of S&P 500 members are beating the index itself. But the rally remains dependent on a handful of large names — Nvidia, Micron, and Apple account for a large share of the index's gains.

A hot CPI print could revive rate-hike fears and pressure stocks, particularly long-duration technology assets whose valuations are most sensitive to discount rates. A softer reading gives the rally room to run. The next FOMC meeting convenes September 15-16, with Warsh scheduled to speak at Jackson Hole on August 27.
