#7月CPI符合预期 U.S. July CPI meets expectations: Rate-hike probability falls, but the “sword hanging over the market” remains

The data came in mildly as expected, with the probability of a September rate hike falling to 36%, but gold first plunged $50 before recovering—the real determinant of the second half will not be this CPI report, but oil prices and WallerU.S. July CPI met expectations across the board, and the market accordingly pushed the probability of a September rate hike from 48% down to 36%. But two layers of overlooked tension are hidden in this “mild” result: First, gold initially plunged $50 after the data before rebounding to new highs, showing that the bullish impact of “meeting expectations” had already been priced in and that the market was really waiting for the next move; second, Brent crude has quietly risen above $90, while Fed Chair Waller’s reaction function is naturally “asymmetric”—soft data can close one door, but hard data opens only one door. For A-shares, the real transmission does not lie in a single reading, but in the unfinished chain of “oil prices—inflation—Waller’s stance.” On the evening of August 12 Beijing time, the U.S. Bureau of Labor Statistics (BLS) released July CPI: headline CPI rose 3.4% year-on-year (versus 3.5% previously, the smallest increase since March) and 0.1% month-on-month, while core CPI rose 2.5% year-on-year (versus 2.6% previously, the lowest since January) and 0.2% month-on-month, with all four figures falling within the market consensus range. The differences among several institutions had been narrow to begin with—some relatively dovish institutions had forecast headline CPI to rise 0.05% month-on-month and core CPI 0.19%, less than 0.1 percentage point away from consensus—so this release served more to “eliminate divergence” than to “create a surprise.” The CME FedWatch Tool showed the probability of a 25-basis-point September rate hike falling from 48% the previous day to 36%, while the probability of no change rose to 64%; the 10-year U.S. Treasury yield fell 2.2 basis points to 4.661%, U.S. stock futures jumped briefly, and spot gold rebounded. At the same time, however, spot gold experienced a “double-sided whipsaw”: It plunged about $50 in the short term after the data, hitting a low of $4,382/ounce, then quickly rebounded and refreshed its intraday high. This tells us that the market was not “celebrating good news,” but “repricing the suspense.” On the evening of August 12 Beijing time, the U.S. Bureau of Labor Statistics (BLS) released July CPI: headline CPI rose 3.4% year-on-year (versus 3.5% previously, the smallest increase since March) and 0.1% month-on-month, while core CPI rose 2.5% year-on-year (versus 2.6% previously, the lowest since January) and 0.2% month-on-month, with all four figures falling within the market consensus range.

How is this different from the previous two months?
The key point is not that “the reading fell again,” but that the cooling has become very narrow, while the seeds of a reversal have already been planted.
First, the cooling was concentrated in energy and housing rather than broad-based. The energy component continued to fall by about 2% month-on-month in July, serving as the biggest drag keeping headline CPI near 3.4%. But this reflects a base effect following the sharp decline in June—cross-checks show that the front-month NYMEX crude oil futures contract rebounded by more than 20% throughout July, while crude was still up 14.7% year-on-year and gasoline was up 24.6%. More importantly, earlier on the day of the data release, Brent crude briefly broke above $90 per barrel, while WTI approached $84. The switch that turns energy from a “drag” into a “boost” has already been turned halfway.
Second, housing has finally loosened, but it remains the anchor of core inflation. Owners’ equivalent rent and primary rent continued to decline, supporting a drop in core CPI to 2.5% year-on-year. This was the first sign of easing in the previously “most stubborn” component. But housing accounts for roughly one-third of the core CPI weighting, and as long as it moves slowly, core inflation will move slowly.
Third, Waller’s reaction function has discounted the significance of “meeting expectations.” He has rejected forward guidance, emphasized that “the data will decide,” and shown zero tolerance for persistently high inflation. Under this stance, the impact of data on rate-hike expectations is inherently asymmetric: Soft data are enough to “close one door” (eliminating September), while strong data “open only one door”—with August nonfarm payrolls and August CPI still standing behind it. This means that the decline in September rate-hike probability from 48% to 36% has “closed one door,” but the door is not locked.
Gold’s “double-sided whipsaw” shows that the upside brought by this reading reflected “cooling suspense” rather than a “new driver.” What can truly determine whether gold moves to the next level is whether oil prices push inflation higher again, as well as Waller’s wording at Jackson Hole.
What is most easily overlooked is that “meeting expectations” had already been priced in—if August inflation or employment comes in stronger, this gain could easily be reversed, and gold’s “double-sided whipsaw” was a preview. In addition, the threat of AI-driven inflation is a new upside risk; if the Strait of Hormuz reopens to shipping, the oil-price logic will quickly reverse; and if Waller reiterates a hawkish stance in his Jackson Hole speech this month, the rate-hike suspense will be repriced. The realization of any one of these factors would push the “mildly positive news” back toward “wait-and-see, or even tightening.”
This CPI report is neither a fanfare for rate cuts nor the end of rate hikes; it simply hands decision-making power to oil prices and the next two data releases. For investors, the real opportunity lies not in chasing a single reading, but in understanding the unfinished chain of “oil prices—inflation—Waller.” #我的七夕交易分享
