Brent Crude Tops $100 as PPI, CPI Data Loom; Fed Rate Hike Uncertainty Persists

Over the next two days, the U.S. will release August PPI and CPI data. Last night, Brent crude briefly broke above $100 per barrel, while WTI climbed to near $95, raising alarm bells. The transmission of oil prices through the industrial production chain has always been one of the most direct and reliable leading signals for predicting PPI trends. Meanwhile, the latest data from the Bank of America Institute and NRF/CNBC Retail Monitor show that consumer card spending and retail growth are clearly cooling—meaning that even if this week's PPI and CPI are pushed higher by oil costs, the root of inflation looks more like a supply shock than demand overheating, and the Fed's rate hike path may not be as straightforward as the market assumes.

1. U.S.-Iran Conflict Escalates: Will Oil Become This Week's Market Time Bomb?

According to CNBC and Rigzone, Brent crude hit an intraday high of $100.45 per barrel last night, up about 2.9% from Tuesday's close of $97.92; WTI rose to above $95, up about 2.4%. From a technical perspective, the market sees WTI breaking out of a symmetrical triangle pattern formed since the March high, with the 100-day moving average crossing above the 200-day moving average. If the current trend continues, a move toward the $100 psychological level cannot be ruled out.

From a supply chain perspective, oil prices spent most of August in the $80 range, have held above $90 since September, and have now broken above $100. Unlike the panic spike in March when the Iran-Israel-U.S. conflict suddenly escalated and Brent surged to near $109 in a single day before gradually falling over the following months, this time it looks more like a sustained climb from the July low of $76. Persistently rising crude costs are enough to leave a clear mark on PPI data over the next 1-2 months through transportation, chemical feedstocks, and energy inputs.

2. This Week's Heavyweights: Can PPI and CPI Settle the September Rate Hike Question?

U.S. Bureau of Labor Statistics data show that July PPI rose 4.7% year-over-year, and core PPI (excluding food, energy, and trade services) also rose 4.7% year-over-year, with core PPI up 0.4% month-over-month, showing a structural pattern of "flat headline, firm core." August PPI will be released at 20:30 Beijing time on September 10. Given the lagged transmission of oil costs, the market is generally cautious about this data. Institutional forecasts suggest core PPI (excluding food and energy, July prior 4.2%) risks rebounding to around 4.6%. If realized, it would mean PPI is turning back up after a brief decline and could push headline PPI above 5% year-over-year.

Following that, August CPI will be released at 20:30 Beijing time on September 11. July CPI was 3.4% year-over-year, and core CPI was 2.5%; market expectations show August headline CPI likely to hold at 3.4%, but core CPI is expected to edge down to 2.4%. This seems to contradict the logic of surging oil prices—core CPI already excludes energy components, and oil price increases have a natural lag in transmission. But more notably, the U.S. Bureau of Economic Analysis (BEA) recently announced it will adjust the statistical methodology for investment advisory services, legal services, and software categories. Goldman Sachs and JPMorgan both estimate that this adjustment could mechanically lower core PCE readings by 0.1-0.2 percentage points. In other words, core inflation "looks milder" partly due to changes in statistical definitions rather than a genuine easing of price pressures—something to be especially careful about when interpreting Friday's data.

3. Are Consumers Tightening Their Wallets? What Card and Retail Data Say

If PPI and CPI are the "thermometers" on the price side, then consumer spending data is the key evidence for judging whether this round of inflation is "demand-driven overheating" or "cost-push." The latest Bank of America Institute Consumer Checkpoint report shows that total credit and debit card spending growth slowed from 6.3% year-over-year in June to 5.0% in July, and excluding gas stations, it fell from 5.6% to 4.3%. However, the report also emphasizes that this cooling is more due to the fading of "temporary factors" such as World Cup-related spending and timing shifts in online promotions, rather than a broad weakening of demand—July's 5.0% year-over-year growth is still among the top three readings in the past three years and more than four times the 2025 full-year average.

Meanwhile, CNBC/NRF Retail Monitor data show that July marked the 10th consecutive month of positive retail sales growth, but the slowdown is more pronounced: retail sales excluding autos and gas stations slowed from 9.41% year-over-year in June to 5.15% in July; if restaurant spending is further excluded, core retail sales (excluding autos, gas stations, and restaurants) growth fell from 10.08% to 4.72%, a drop of more than 5 percentage points.

4. Fed's Warsh vs. Waller: How Much Suspense Remains for the September 17 Meeting?

Former Fed Governor Kevin Warsh's remarks at the Jackson Hole symposium on August 28 turned notably hawkish, hinting that persistently high inflation may require rate hikes, and the market widely interpreted this as a significant increase in the probability of a September hike. But Fed Governor Christopher Waller said on September 3 that if the recent "disinflation" trend continues, he would lean toward supporting keeping rates unchanged in September—creating a divergence in market expectations ahead of the meeting.

Whether the final decision in the early hours of September 17 (Beijing time) is a hike or "hold with hawkish guidance," the directional shift is already fairly clear: the Fed's policy narrative is moving from "no more hikes this year" to "not ruling out further tightening." Taken together with the core PCE methodology adjustment mentioned earlier, this also shows that under the Fed's "data-dependent" decision framework, the interplay between different data components and statistical definitions itself influences market expectations.

5. UBS Reversal: From "No Hikes All Year" to Expecting Two Hikes—What Assets Do the Giants Favor?

Notably, UBS analysts abandoned their previous forecast of no rate hikes in 2026 and now predict the Fed will hike by 25 basis points each in September and December, bringing the federal funds rate range to 4.00%-4.25%. A key judgment in the UBS report is: "Tightening conducted against a backdrop of resilient GDP growth, strong AI capital spending, and a solid labor market has historically supported risk assets." This is fundamentally different from a scenario of "forced rate hikes to combat inflation amid weak economic growth"—UBS believes the current situation is closer to the former, i.e., "growth-driven rate hikes" rather than "inflation-driven rate hikes." Based on this judgment, UBS's asset allocation recommendations are as follows:

Stocks: Maintain a constructive view on equities throughout the rate hike cycle, continue to favor three themes—artificial intelligence, power/resources, and longevity—and view short-term volatility as an opportunity to buy on dips.

Bonds: Raise U.S. Treasury yield forecasts, with the 2-year yield target raised to 4.25% (June 2027) and the 10-year to 4.5%; the relative attractiveness of short-duration bonds has declined somewhat, but medium- to long-duration high-quality bonds still have allocation value, providing coupon income and acting as a hedge when economic growth slows.

Dollar: Tightening expectations are positive for the dollar in the short term, but UBS also cautions that if subsequent hikes prove to be "inflation-driven" rather than "growth-driven," this support may not be sustainable.
