The upcoming Consumer Price Index (CPI) report for April is anticipated to reveal a notable uptick in inflation, a trend that may temporarily obscure underlying disinflationary pressures. Headline CPI is projected to increase by approximately 0.58% month-over-month, a deceleration from March's robust 0.87% rise, but still indicative of persistent price pressures. Conversely, core CPI, which excludes volatile food and energy components, is expected to reaccelerate, climbing to an estimated 0.36% from the previous month's 0.20%. On an annual basis, headline inflation is likely to climb to 3.7% from 3.3%, while core inflation is forecast to edge up to 2.7% from 2.6%. This projected rise in core inflation momentum, with 1-month annualized figures seen at 4.4%, 3-month at 3.1%, and 6-month at 3.0%, suggests that underlying price pressures remain a concern for policymakers.
Energy prices are expected to be a significant contributor to the headline CPI figure, accounting for an estimated 24 basis points. Gasoline prices, in particular, are anticipated to surge by another 7% in April, a substantial increase, though considerably less dramatic than the 21% spike observed in March. This surge in energy costs is largely attributed to geopolitical tensions, specifically the conflict involving Iran, which has impacted global oil supply expectations and, consequently, fuel prices. The ripple effect of higher energy costs is expected to influence transportation expenses and potentially other sectors of the economy.
Food inflation is also predicted to rebound after a flat reading in March. Rising grocery prices are expected to lead this resurgence, indicating that consumers may face higher costs for essential food items. While restaurant inflation might show signs of a slight cooling, the overall trend in food prices suggests a renewed upward pressure on household budgets. The combination of rising energy and food costs presents a challenge for consumers, potentially impacting discretionary spending as more income is allocated to necessities.
Shelter inflation is poised to be a major driver of core services inflation. Rents and owners' equivalent rent (OER) are expected to rebound sharply. This rebound is attributed, in part, to lingering statistical distortions within the Bureau of Labor Statistics (BLS) survey data. These distortions are a consequence of disruptions caused by last year's government shutdown, which affected the timing and accuracy of data collection. As the BLS corrects these anomalies, shelter costs are expected to reflect a more accurate, albeit temporarily higher, picture of the housing market.
Beyond shelter, several other service categories are expected to contribute to sticky inflation. Airfares are projected to increase, influenced by rising jet fuel costs and increased travel demand. Vehicle insurance premiums are also anticipated to continue their upward trend, reflecting higher repair and replacement costs. Transportation costs, in general, are likely to remain elevated, adding to the overall inflationary pressure within the services sector. These persistent increases in service costs are a key focus for central banks monitoring inflation.
In contrast to the rising costs in energy and services, some discretionary categories are expected to experience outright deflation. Hotel prices, car rentals, and admission fees are all predicted to soften. This divergence suggests that while essential goods and services are becoming more expensive, consumers may find some relief in non-essential spending areas. This pattern echoes previous instances where tariffs and supply chain adjustments led to price softness in certain discretionary sectors, offsetting broader inflationary trends.
Core goods inflation is expected to remain relatively contained, despite a rebound in used car prices. Weakness in apparel, appliances, and new vehicle prices is anticipated to offset broader price pressures in the goods sector. The used car market's rebound is influenced by factors such as supply chain issues for new vehicles and increased demand. However, the overall trend in goods suggests that manufacturers and retailers are facing mixed pricing environments, with some categories experiencing downward pressure while others remain stable or slightly increase.
The market's attention is likely to be less focused on the headline CPI figure and more on whether the persistence of sticky shelter and services inflation signals a more challenging "last mile" in the fight against inflation for the Federal Reserve. The concern is that these underlying pressures may indicate that disinflation is not proceeding smoothly, potentially complicating the Fed's path toward its inflation targets and influencing its monetary policy decisions. The uneven nature of inflation, with some sectors rising sharply while others cool, creates a complex picture for economic forecasting and policy setting.
Following a brief period of disinflation relief in March, the April CPI report is expected to serve as a reminder that the battle against inflation is far from over. The anticipated acceleration in core inflation, moving back to 0.4% month-over-month from 0.2%, reinforces concerns that underlying price pressures are stubbornly embedded. This suggests that the Fed may need to maintain a cautious stance on monetary policy, balancing the need to control inflation with the risks of slowing economic growth. The range of forecasts for April CPI, spanning from 0.4% to 0.8% for the headline number, highlights the considerable uncertainty surrounding the inflation outlook.
March's CPI data already underscored the volatility of inflation trends, with consumer prices reaching their highest annual pace since May 2024. This surge was largely driven by a significant increase in energy costs, including a substantial jump in gasoline prices. For markets already anxious about the timing of potential Federal Reserve interest rate cuts, another firm CPI print could reinforce the perception that inflation is not steadily declining but rather moving in unpredictable waves. This scenario could leave policymakers in a difficult position, caught between the need to address inflation and the potential for exacerbating an economic slowdown.
Bloomberg Economics anticipates that the April CPI report will present a surface-level inflation picture that is hotter than the underlying trend might suggest. While the conflict in Iran is contributing to higher gasoline and airfare prices, a significant portion of the expected firmness in core inflation appears to be linked to a technical rebound in shelter inflation. This rebound is a correction of distortions caused by the government shutdown in October, which affected the BLS's data collection for rents and OER. Bloomberg estimates that without this specific rent-related adjustment, core CPI would have registered a more subdued 0.24% in April, even with rising airfare costs and ongoing pressures in sectors like memory chips and computer components.
Furthermore, Bloomberg points to certain discretionary segments of the economy, such as hotels, car rentals, and admissions, which are still experiencing outright deflation. This observation aligns with patterns seen after previous tariff implementations, where softness in discretionary services helped to offset inflation in goods. This suggests that while some sectors are facing inflationary pressures, others are experiencing price declines, creating a mixed inflation landscape.
The Cleveland Fed's current estimate, or "nowcast," for April headline CPI stands at 0.45% month-over-month, with core inflation at 0.21%. Barclays analysts suggest that the shelter adjustment alone could add approximately 10 basis points to core inflation. Goldman Sachs forecasts a firm CPI reading but believes that, beneath the surface, it may be less alarming than market participants fear. The bank projects core CPI to rise by 0.31% month-over-month, slightly below the consensus range of 0.3%-0.4%, which would result in an annual core inflation rate of 2.67%. Headline CPI is expected to increase by 0.58% on the month, driven by a significant 4.6% surge in energy prices, including gasoline costs influenced by the Iran conflict, and a modest 0.3% rise in food prices, pushing annual headline inflation to 3.68%.
Goldman Sachs' perspective reinforces the growing market sentiment that much of the near-term inflation surge is concentrated in energy and a limited number of supply-constrained categories, rather than being a broad-based reacceleration across the entire consumer basket. The bank anticipates that the April CPI report will be heavily influenced by two powerful, albeit temporary, forces: a technical rebound in shelter inflation and a war-driven spike in travel costs. Goldman forecasts a sharp, one-time acceleration in both owners' equivalent rent (OER) and primary rents. OER is expected to rise by 0.50%, and rents by 0.44%, as the BLS effectively corrects for missed housing data collection during last year's government shutdown. Because shelter inflation is calculated using a six-month rotating sample, a portion of the housing basket that should have been surveyed in October recorded artificially flat prices. This distortion is now reversing in April, temporarily making shelter inflation appear significantly higher than the underlying trend.
Simultaneously, Goldman Sachs anticipates that inflation in travel services will intensify due to the conflict in Iran impacting transportation costs. Airfares are projected to jump by 3% month-over-month, as increased jet fuel prices are passed on to consumers. Hotel prices, however, are expected to remain flat despite broader inflationary pressures, reflecting softer demand signals observed in alternative pricing data. The combination of the shelter rebound and the spike in travel-related prices is likely to give the April CPI a hotter appearance, even as some underlying discretionary categories continue to cool.
Within the automotive sector, Goldman Sachs foresees a mixed picture, further supporting the theme of uneven inflation pressures rather than universal acceleration. Used car prices are forecast to decline by 0.4%, mirroring softer trends in wholesale auction markets. New vehicle prices are expected to increase slightly by 0.1%, as automakers make minor adjustments to sales incentives. Auto insurance premiums, however, are projected to remain sticky, with another 0.4% increase, highlighting how service-related costs, such as labor, repairs, and replacement expenses, continue to outpace inflation in many goods categories. This persistent rise in insurance costs reflects broader trends in service sector inflation.
Goldman Sachs also notes that the April CPI report will incorporate a semiannual methodological update to the health insurance component. This adjustment is expected to result in unusually large monthly declines of approximately 1.5% for the next six reports. Crucially, this is characterized as a statistical adjustment rather than a reflection of collapsing healthcare costs. Because the CPI and Personal Consumption Expenditures (PCE) inflation measures utilize different source data for health insurance, this drag will not affect the Fed's preferred PCE inflation gauge. Therefore, while the CPI details may appear softer in this specific category over the coming months, policymakers are unlikely to interpret it as significant evidence of fading underlying inflation pressure.
Looking ahead, Goldman Sachs anticipates that tariffs and elevated energy costs linked to the Iran war will continue to exert modest upward pressure on inflation in the coming months. However, the bank still expects core CPI to settle back toward the 0.2% monthly range, barring a more prolonged oil shock. For financial markets, the critical question is shifting from whether energy prices are rising to whether the war-driven oil surge will begin to permeate more broadly into consumer inflation and affect consumer behavior. Federal Reserve officials appear increasingly focused on the persistence of inflation, particularly within a relatively stable labor market context. Despite this, traders may be hesitant to aggressively price in renewed Fed rate hikes, even if the CPI report surprises to the upside. Much of the current inflation impulse is viewed as being driven by geopolitical factors rather than by robust domestic demand.
This tension was evident in the April FOMC meeting, where three dissenting members—Beth Hammack, Neel Kashkari, and Lorie Logan—opposed language that retained even a mild easing bias. They argued that inflation risks had sufficiently risen to warrant keeping all policy options open, including maintaining higher interest rates for an extended period or potentially implementing further hikes if necessary. Market participants also noted a subtle but significant hawkish shift in the Fed's inflation commentary. Officials dropped the phrase "inflation remains somewhat elevated" in favor of simply stating "elevated," explicitly linking the concern to the recent surge in global energy prices. This linguistic change signals a heightened awareness of inflation risks.
JPMorgan's analysis of the upcoming CPI report suggests that markets are less concerned about the headline inflation spike driven by the war in Iran and are far more focused on whether core inflation begins to accelerate persistently beneath the surface. The bank's scenario analysis indicates a clear asymmetry regarding the core CPI print. An upside surprise exceeding 0.45% month-over-month is seen as potentially triggering a sharp decline of 1.25% to 2.0% in the S&P 500. Conversely, a softer print below 0.30% would likely lead to a more modest rally of 1.0% to 1.5%. The market's perceived "safe zone" appears to be around the 0.35% to 0.40% range, where equities are expected to remain broadly range-bound. Meanwhile, options markets are pricing an implied one-day S&P 500 move of approximately 0.8%, indicating that traders still consider the report a significant event for market volatility, despite widespread expectations of a war-driven energy price surge. JPMorgan's Market Intel desk posits that while the obvious inflation narrative centers on the surge in oil prices following the Strait of Hormuz incident, the market's true sensitivity lies with core inflation due to its tighter correlation with the Federal Reserve's policy decisions and its impact on longer-term inflation expectations.
