The Bureau of Labor Statistics reported consumer prices rose 3.4% over the past year in August, driven by a gasoline surge that accounted for more than a third of the monthly increase, and economists say the worst energy pressures may not even show up in the data yet.
The August Consumer Price Index climbed 0.4% from July, a sharp jump from the prior month's 0.1% reading. Core prices, which strip out volatile food and energy costs, rose 0.3% on the month and 2.4% year over year. The headline figures landed roughly in line with estimates from economists polled by LSEG, but the core monthly number came in slightly hotter than forecast, a detail that matters as the Federal Reserve prepares for its next interest rate decision.
That meeting is days away. Fed Chair Kevin Warsh and central bank policymakers will gather next week to decide whether to raise rates again from the current target range of 3.5% to 3.75%. Market odds already reflect where traders think this is headed: the CME FedWatch tool showed an 85.6% probability of a 25-basis-point hike, up from 72.4% a day earlier and 59.4% just one week ago.
Energy prices rose 2.1% in August on a monthly basis and sat 16.3% above year-ago levels. Gasoline alone jumped 3.9% for the month and 27.4% year over year. The BLS noted that the gasoline index accounted for more than one-third of the overall CPI increase.
That reversal stings. Energy prices had been falling, down 5.7% in June and another 1.5% in July. August erased that relief and then some.
Goldman Sachs Asset Management's Alexandra Wilson-Elizondo, the firm's global head and co-chief investment officer of multi-asset solutions, warned that the report may actually understate the problem. As she told Fox Business:
"The challenge is that the data does not fully capture some of the inflation pressures that have emerged more recently, and there is little evidence to suggest inflation is returning to target in the near-term. The survey period predates the latest move higher in energy prices, with Brent crude climbing above $100 as tensions around the Strait of Hormuz persist."
In other words, the August data was collected before the latest oil price spike. Brent crude above $100 a barrel, fueled by geopolitical tension near a chokepoint for global oil shipments, means September's numbers could look worse.
Wilson-Elizondo called next week's Fed rate decision "a jump ball," noting that while the CPI came in broadly as expected on the surface, the underlying pressures leave little room for optimism about inflation returning to target soon.
Energy grabbed the headlines, but the price increases were broad. Housing costs rose 0.3% in August, with the shelter index running 3% above year-ago levels. Tenants' and household insurance costs held flat month to month but remained 4.1% higher than last year.
Transportation services climbed 0.5% for the month and 2.4% annually. Airline fares stood out: up 2.7% in August and a staggering 23.4% compared with a year earlier, driven in part by higher jet fuel costs feeding directly into ticket prices.
Food prices ticked up 0.1% overall. Groceries, the "food at home" index, held flat from July but still ran 2.2% above last year. Eating out cost more: the food-away-from-home index rose 0.3% for the month and 3.4% year over year. For families trying to save money by cooking at home, the math offered only marginal relief.
Beef and veal prices dipped 1% in August, a small monthly reprieve, but remained 5.9% higher than a year ago. Egg prices rose 2.9% on the month, though they sat 23% below year-ago levels following last year's avian flu-driven spike. Fruits and vegetables fell 0.4% monthly, with lettuce dropping 6.2% in August alone.
Electricity offered one of the few genuine bright spots, falling 0.2% on a monthly basis. Even so, electricity costs remained 3.8% higher than last year.
Heather Long, chief economist at Navy Federal Credit Union, did not mince words about what the data means. She characterized the August figures as hotter than expected, particularly on core inflation, and pointed to the breadth of the problem:
"Fed Chair Kevin Warsh says he's watching how broad-based the inflation problem is. And right now, it's a wide problem. Restaurants, new and used vehicles, shelter and transportation all had sizable gains in August. The Federal Reserve needs to hike in September to prevent this from worsening."
Long framed the situation bluntly: "America has an inflation problem and it's more than just high gas and diesel prices."
It is worth noting a tension in the data's reception. The article's own reporting described the headline CPI figures as in line with LSEG economist estimates, while Long characterized the data as "hotter than expected." The core monthly reading, 0.3% versus the prior month's 0.2%, came in slightly above forecast, which may explain the divergence. But the gap between "as expected" and "hotter than expected" matters when the Fed is deciding whether to raise borrowing costs for every household and business in the country.
Stock markets rose in morning trading after the report. The S&P 500 gained 0.91%, the Dow Jones Industrial Average climbed 0.96%, and the Nasdaq Composite added 0.98%. The rally suggested investors saw the data as clearing the path for a rate hike rather than signaling a deeper inflation crisis, at least for now.
Vanguard senior economist Josh Hirt said the August CPI report makes a Fed rate hike in September more likely, reinforcing the market consensus reflected in the FedWatch numbers.
But a rate hike is not free relief. Higher rates mean more expensive mortgages, car loans, and credit card payments. For families already paying 3.4% more for everyday goods than they were a year ago, and 27.4% more for gasoline, the Fed's medicine comes with its own cost.
The underlying picture is what should concern policymakers most. Energy had been cooling through the summer, giving households a modest break. August reversed that trend decisively. And if Wilson-Elizondo's analysis is right, that the survey period missed the worst of the recent crude oil run-up, then September's inflation reading could be uglier still.
Tensions near the Strait of Hormuz, through which roughly a fifth of the world's oil supply passes, add a geopolitical wildcard that no domestic policy can easily neutralize. With Brent crude above $100, the pressure flows straight through the supply chain: into gasoline, into jet fuel, into airline tickets, into shipping costs, and ultimately into the price of nearly everything.
Core inflation at 2.4% year over year remains above the Fed's 2% target. Shelter costs keep grinding higher. Eating out keeps getting more expensive. The categories where prices fell, lettuce, electricity, eggs compared with last year's crisis levels, are narrow exceptions, not signs of a broader retreat.
Americans do not need an economist to tell them prices are too high. They see it at the pump, at the grocery store, and on their rent statements every month. The question is whether Washington's institutions, the Fed included, will act with enough urgency to match what families already know from their own checkbooks.
