CPI Preview: Inflation Expected to Cool… Just Before the Oil Spike Hits

The February Consumer Price Index report, due Wednesday at 8:30 a.m. ET, will serve as the first major inflation checkpoint of a week packed with critical economic data. Investors will not only be parsing the CPI figures themselves, but also trying to gauge what they imply for the upcoming Producer Price Index (PPI), the Federal Reserve’s preferred inflation gauge—the Personal Consumption Expenditures (PCE) index—and the University of Michigan’s inflation expectations survey. While February’s numbers are expected to show relatively contained inflation, markets are already looking ahead to new risks building in the inflation outlook, particularly from the recent spike in oil prices tied to escalating geopolitical tensions involving Iran.

Economists generally expect February inflation to show only modest changes from January. Consensus estimates point to headline CPI rising 0.3% month over month in February, up slightly from January’s 0.2% increase. On a year-over-year basis, headline inflation is expected to hold steady at roughly 2.4%. Core CPI—which excludes the volatile food and energy categories and is closely watched by policymakers—is expected to increase around 0.2% to 0.3% month over month. Most economists are clustering around a 0.2%–0.3% range, with Citi projecting a 0.23% monthly increase. On a yearly basis, core CPI is expected to remain around 2.5%, roughly unchanged from the prior month.

January’s CPI report offered some encouragement for investors hoping inflation is slowly moving toward the Federal Reserve’s 2% target. Headline CPI rose 2.4% year over year in January, while core inflation cooled modestly as used-car prices fell and gasoline prices declined roughly 3.2%. The monthly core CPI increase of roughly 0.30% largely matched economist expectations but featured a different internal mix than analysts had anticipated. Core goods prices were softer than expected thanks to declining vehicle prices, while services inflation—particularly in categories like medical services and travel—came in somewhat stronger. Even so, services inflation did slow compared with the sharp increases typically seen in January, offering some evidence that underlying price pressures may be gradually easing.

For the February report, analysts will be watching several key components that have been driving inflation trends over the past year. Shelter inflation remains the single largest contributor to core CPI and continues to be closely monitored by the Federal Reserve. Many economists believe shelter inflation is poised to soften further in the coming months as slower rent growth and weaker housing market conditions begin filtering into official data. Citi and several other banks expect shelter inflation to rise roughly in line with January’s pace, around 0.23% month over month, but the broader trend should remain downward as rental market data from sources like Zillow show cooling rent increases.

Another important category to watch is core services excluding shelter, which includes travel-related costs such as airline tickets, hotels, and medical services. These categories showed unusually strong gains earlier in the year, and some economists expect a partial reversal in February. Travel demand appears to have normalized, with hotel occupancy and airline traffic returning to seasonal patterns after two months of unusually strong pricing power. Medical services prices also surged in January, suggesting some mean reversion may occur in the February data.

Core goods prices represent another area of focus. After providing disinflationary relief for much of the past year, goods prices may be starting to show renewed pressure. Analysts expect some rebound in used-car prices following stronger wholesale auction prices late last year. Tariffs also continue to filter through supply chains, potentially keeping goods inflation running slightly above its pre-pandemic pace. While Citi expects the pass-through from tariffs to begin moderating after February, some economists warn that new upside risks to goods inflation have begun to emerge in recent weeks.

Food prices are expected to provide some relief for consumers. Economists anticipate grocery prices could decline slightly in February, potentially falling around 0.1% month over month. Lower agricultural commodity prices and easing wage pressures in grocery retailing have helped stabilize food inflation. Meanwhile, restaurant prices—known as “food away from home”—are expected to rise modestly, though likely at a slower pace than the roughly 0.33% monthly average seen last year.

Energy prices are another major factor, although the February CPI report will likely offer only a partial glimpse of the energy dynamics currently shaping markets. Gasoline prices were already edging higher in February, with economists estimating a roughly 0.8% increase during the month. However, the dramatic surge in oil prices tied to the recent Middle East conflict and fears of supply disruptions around the Strait of Hormuz occurred largely in early March. As a result, the February CPI data will largely capture inflation conditions before the latest geopolitical shock to energy markets. Many economists believe the real inflation impact of the Iran conflict will not show up in official data until the March or April CPI reports.

For the Federal Reserve, the February CPI release will be an important—but not decisive—data point. Policymakers remain focused on whether inflation continues trending gradually toward their 2% target, particularly in the core services and shelter categories. The Fed has already reduced interest rates by roughly 1.75 percentage points during the current easing cycle in response to a cooling labor market, but officials have recently adopted a more cautious stance. With inflation still above target and new risks emerging from energy markets, the central bank is widely expected to hold rates steady in the near term.

Markets are also paying close attention to the divergence between CPI and the Fed’s preferred inflation gauge, the PCE index. Recently, core CPI has been running slightly below core PCE inflation, partly due to differences in how financial services and healthcare are weighted in the two indexes. Economists expect that gap to narrow in coming months, though the broader message remains the same: inflation is slowing but still running closer to 3% than the Fed’s long-run goal.

For investors, Wednesday’s CPI report may matter less for what it says about February and more for what it signals about the inflation path ahead. If core inflation continues to moderate, Treasury yields could fall and equity markets may gain confidence that the Fed still has room to ease policy later in the year. But if inflation remains stubbornly high—or if rising energy costs begin feeding into broader price pressures—markets may start questioning whether rate cuts will be delayed further into the future.

Either way, the February CPI report will kick off a crucial stretch of inflation data that could shape expectations for monetary policy and financial markets throughout the spring.
