| Above 2.6% | 76.0% | 79.9% | Core PCE data rose to 3.2%, suggesting upward pressure on Core CPI. |
| Above 2.5% | 93.0% | 94.5% | Forecasts anticipate Core CPI to rise, driven by geopolitical tensions. |
| Above 2.8% | 14.0% | 15.2% | Several forecasts anticipate April Core CPI to rise due to ongoing inflationary pressures. |
| Above 2.9% | 6.0% | 8.6% | Recent Core PCE surge and persistent sticky services suggest a substantial rise in Core CPI. |
Current Context
Official core inflation data for April 2026 is due soon. The U.S. Bureau of Labor Statistics (BLS) is scheduled to publish the Consumer Price Index for April 2026, which includes Core CPI year-over-year (YoY), on Tuesday, May 12, 2026, at 8:30 a.m. (ET) [^][^][^]. In March 2026, the Core CPI, which excludes volatile food and energy prices, increased by 2.6% year-over-year [^][^][^]. Looking ahead to April, CME Group indicates that Core CPI is projected to be 2.8% [^]. Goldman Sachs had forecast March Core CPI at 2.6% and expects it to ease further to 2.1% by the end of 2026 [^].
Inflation trends significantly impact the Federal Reserve's monetary policy. Goldman Sachs anticipates a deceleration in core inflation, even as geopolitical factors, such as the Iran war, have driven up headline inflation due to energy price spikes [^]. The Federal Reserve Bank of Cleveland's "Inflation Nowcasting" tool projected a trailing 12-month inflation increase to 3.56% for April, though this appears to refer to headline CPI rather than core inflation [^]. Following its April 2026 meeting, the Federal Open Market Committee (FOMC) maintained the federal funds rate target range at 3.50%-3.75% [^]. Market expectations suggest that the Federal Reserve is likely to keep interest rates unchanged, with prospects for rate cuts being pushed back to later in 2026, and some economists even anticipate no rate cuts throughout the year [^][^][^][^][^][^].
2. Market Behavior & Price Dynamics
Historical Price (Probability)
Outcome probability
Date
Based on the provided chart data, this market opened with a very high probability of a "Yes" outcome at 95% and has since climbed to 99%. The price action has been characterized by a single, distinct upward movement followed by a period of stability. Between April 24 and May 1, the price jumped from 95% to 99%, where it has remained. This sharp increase suggests that information or analysis emerged during that week which significantly strengthened the market's conviction that the April 2026 core inflation rate will be at or below 2.1%. This reflects a strong expectation for a notable deceleration from the 2.6% core inflation rate reported for March 2026.
The total trading volume of 200 contracts is relatively low, indicating limited market participation despite the high level of confidence expressed by the price. The lack of volume spikes during the price increase may suggest the move was due to a shift in consensus rather than a high-volume trading event. The price has established a firm support level at 95% and is now testing resistance at the 99% ceiling, which represents near-certainty. Overall, the market sentiment is overwhelmingly bullish on the prospect of core inflation coming in at or under 2.1%. The stable 99% price indicates that participants see a "No" outcome as a very low probability event ahead of the official data release.
3. Significant Price Movements
Notable price changes detected in the chart, along with research into what caused each movement.
📈 April 30, 2026: 9.0pp spike
Price increased from 90.0% to 99.0%
Outcome: Above 2.2%
What happened: The primary driver of the 9.0 percentage point spike on April 30, 2026, was the traditional news announcement of the March 2026 Core PCE YoY data, which was released on the same day and showed a significant increase to 3.2% [^][^]. This reading, the highest since November 2023, signaled accelerating underlying inflation and likely prompted market participants to revise their expectations upwards for all core inflation measures, including the forthcoming April 2026 Core CPI [^][^]. No specific social media activity was identified as a driver for this movement in the provided information. Social media was (d) irrelevant.

Market Discussion
Core inflation (Core CPI YoY) in March 2026 stood at 2.6%, following a 0.2% month-over-month increase [^]. Current consensus forecasts anticipate Core CPI YoY for April 2026 to remain around 2.6% [^], though prediction markets suggest a high probability of the monthly increase being above 0.2% or even 0.3% [^]. Looking further ahead, Goldman Sachs projects Core CPI to moderate to 2.1% by the end of 2026 [^].
5. What potential supply chain developments or geopolitical events could significantly alter the disinflationary path projected by institutions like Goldman Sachs before April 2026?
| Core Inflation Impact per $10 Oil Increase | 3–6 bp [^] |
|---|---|
| Global Seaborne Fertilizer Feedstocks via Strait of Hormuz | One-third [^] |
| Helium Supply Normalization Post-Disruption | 4–6 months after ceasefire and reopening [^] |
Geopolitical events, particularly in the Middle East, could disrupt disinflationary trends. Potential supply chain developments and geopolitical events, specifically disruptions in the Middle East related to the Strait of Hormuz and accelerated tariff pass-through, pose significant risks to the projected disinflationary path before April 2026. Such events are capable of substantially increasing underlying core inflation measures [^]. Research indicates that if energy disruption persists until May, oil prices could test $140 per barrel or more and remain above $100 through year-end. Each $10 increase in oil prices is estimated to add approximately 3-6 basis points to core inflation [^].
The Strait of Hormuz poses significant non-energy supply chain inflation risks. Beyond energy, the Strait acts as a crucial chokepoint, with potential disruptions propagating into core inflation through non-energy supply chains. This could impact commodities such as food, feed, fertilizer, helium, and aluminum [^]. For instance, one-third of global seaborne fertilizer feedstocks pass through the Strait, making its closure or disruption a substantial amplifier of inflationary consequences [^]. Turmoil related to Hormuz has already led to helium price spikes, and normalizing supply could take 4-6 months even with a ceasefire and the Strait reopening, implying continued cost pressure into spring 2026 [^].
Accelerated tariff pass-through also presents a distinct risk to disinflation. Separately, tariffs represent another potential inflationary pressure. The accelerated pass-through of these costs to consumer prices could delay or even reverse disinflation, a concern identified for early 2026 [^].
6. How do the inflation forecasting models from the Federal Reserve Bank of Cleveland and CME Group differ in their key assumptions and historical accuracy?
| Cleveland Fed Core Inflation Assumption | Core inflation in coming months equals prior 12-month average [^] |
|---|---|
| Cleveland Fed Core Inflation Accuracy | Comparable to statistical models, more accurate than some survey-based nowcasts [^][^] |
| CME Group Core-CPI Forecasting Model | No comparable model with documented assumptions or historical accuracy found [^][^][^] |
The Cleveland Fed's model assumes core inflation stability. Its core inflation nowcast relies on the premise that core inflation in forthcoming months will be equal to its average reading over the preceding 12 months [^]. This model has demonstrated an accuracy for core inflation that is comparable to competing statistical models and superior to some survey-based inflation nowcasts [^][^]. Evaluations conducted between 1999 and 2022, including a post-COVID sample, support these performance conclusions [^][^].
CME Group lacks detailed core-CPI forecasting model information. While CME Group content describes CPI/core-CPI definitions and products such as FedWatch, it does not specify a forecasting model with documented assumptions or a historical accuracy evaluation comparable to that provided by the Cleveland Fed [^][^][^]. Therefore, a direct comparison of key assumptions and historical accuracy between the core-inflation forecasting models of the two entities is limited by the absence of comparable information for the CME Group [^][^][^].
7. What is the historical trend of revisions in the FOMC's Summary of Economic Projections (SEP) for core inflation, and what does it suggest for 2026?
| 2026 Core PCE Forecast | 2.7% (March SEP median) [^][^][^] |
|---|---|
| Historical Final SEP Revision | Typically higher than initial forecast (net upward revision), except 2020 [^] |
| Recent Core PCE Actuals | 3.2% in March 2026, 3.1% in January 2026 [^][^] |
FOMC core inflation forecasts show distinct historical revision patterns. From 2012 to 2020, core Personal Consumption Expenditures (PCE) forecasts generally overpredicted actual inflation, which led to subsequent downward revisions [^]. Conversely, between 2021 and 2023, forecasts underpredicted actuals during a period of surging inflation, resulting in upward revisions [^][^]. A consistent historical trend indicates that the final Summary of Economic Projections (SEP) for a given year typically shows a higher core inflation rate than its initial forecast, reflecting a net upward revision, with 2020 being an exception to this pattern [^].
The 2026 core PCE forecast may see further adjustments. The March 2026 SEP median core PCE forecast stands at 2.7% [^]. This figure represents an upward revision of 0.1 percentage points from the September 2025 projection, with the full range of projections spanning 2.5–3.1% [^][^][^]. Given the historical tendency for forecasts to be revised upward when they underpredict actuals [^][^], and the general pattern of net upward revisions by year-end [^], the March 2026 SEP median core PCE forecast of 2.7% could be subject to further adjustments. This consideration is particularly pertinent as recent actual core PCE inflation rates were 3.2% year-over-year in March 2026 and 3.1% in January 2026, both exceeding the current median forecast [^][^].
8. Which components of the Core CPI basket (e.g., shelter, services ex-housing) present the greatest uncertainty or upside risk through early 2026?
| Shelter YoY | +3.0% (March 2026) [^] |
|---|---|
| Services (ex-energy) YoY | +3.8% (March 2026) [^][^] |
| Hospital/Related Services YoY | +7.6% (March 2026) [^] |
Key components pose significant uncertainty for inflation through early 2026. Shelter, services excluding housing, and healthcare-related subcomponents are identified as primary sources of uncertainty and upside risk for inflation through early 2026. These sectors are key channels for persistent price pressures, with March 2026 data showing shelter up +3.0% year-over-year and services (excluding energy) up +3.8% year-over-year, potentially sustaining upside risk into later 2026 [^][^].
Shelter's structural lag and services ex-housing drive core inflation risks. Shelter carries upside risk for Core CPI into early 2026 due to its structural lag, as the Bureau of Labor Statistics (BLS) shelter reflects rent agreements with a 12–18 month lead/lag relationship compared to market rent indicators [^][^]. This means the timing and magnitude of inflation could differ from forecasts. Services excluding housing are also noted as a significant upside-risk channel for underlying core inflation, indicating worsening price pressures toward the end of 2025 and suggesting a risk of firmer-than-expected early-2026 core services inflation [^].
Healthcare services present notable uncertainty within broader core inflation. Within services, healthcare-related subcomponents are a particular source of uncertainty and upside risk [^]. A March 2026 commentary highlights hospital and related services at +7.6% year-over-year, emphasizing healthcare services as an area of pressure within core inflation and noting uncertainty around health-insurance measurement [^]. Overall, the macro upside-risk narrative for 2026 suggests mechanisms that could raise core inflation through services rather than goods, consistent with an upside skew for sticky services components [^].
9. Which specific economic indicators, beyond CPI itself, are most likely to influence the Federal Reserve's policy stance before the April 2026 report?
| Fed's Official Target | 2% Core PCE YoY [^][^][^] |
|---|---|
| March 2026 Core PCE | +3.2% [^] |
| Core services ex-housing PCE (3-mo annualized Dec 2025) | 3.9% [^] |
The Federal Reserve prioritizes Core PCE for monetary policy decisions. The Federal Reserve's policy decisions are primarily guided by Core Personal Consumption Expenditures (PCE) Year-over-Year, distinguishing its approach from reliance on the Core Consumer Price Index (CPI) [^][^][^]. The Fed's official inflation target is explicitly set at 2% for Core PCE YoY, which it prefers for informing its monetary policy stance [^][^][^].
Recent inflation data and labor conditions shape policy outlook. Current data shows the March 2026 Core PCE at +3.2% [^]. Furthermore, Core services ex-housing PCE, which measured 3.9% on a 3-month annualized basis in December 2025, has been identified as signaling persistent inflationary pressures [^]. The Federal Open Market Committee's (FOMC) statements consistently emphasize the significance of 'labor market conditions, inflation pressures and inflation expectations' in their deliberations [^][^]. These key factors informed the April 2026 FOMC's decision to maintain the federal funds rate at 3.5-3.75% [^].
10. What Could Change the Odds
Key Catalysts
The April 2026 Core Consumer Price Index (CPI) year-over-year (YoY) is scheduled for release on Tuesday, May 12, 2026, at 8:30 a.m. ET [^][^][^]. This data, which excludes volatile food and energy prices, is a critical indicator for assessing underlying inflation trends and informing monetary policy decisions [^][^][^]. The previous Core CPI for March 2026 was reported at 2.6% [^]. Market probabilities currently suggest an 82% chance of the month-over-month (MoM) increase being above 0.2% and a 53% chance of it exceeding 0.3% [^]. Analysts offer varying projections for 2026, with J.P. Morgan forecasting a 3.2% YoY Core CPI, while Goldman Sachs anticipates an easing from 2.6% in March to 2.1% by the end of the year [^][^].
Potential catalysts that could lead to a higher-than-expected Core CPI include rising energy prices due to geopolitical tensions, such as the Iran war, which have driven up crude oil and natural gas costs and are likely to be passed on to consumers [^] [^] [^] [^] . Gasoline prices saw a significant increase in March 2026 [^][^][^]. A tight labor market and elevated wage growth, such as the 3.7% YoY recorded in Q1 2026, are also significant contributors to persistent core services inflation [^][^][^]. Additionally, lagged effects of tariffs continue to add to goods inflation, with an estimated 72% of tariff costs passed to consumers after 12 months [^][^]. There is also a possibility of a surprise jump depending on how the Bureau of Labor Statistics addresses missing October data [^][^][^][^], and housing and auto insurance are expected to gain relative weight in the CPI basket, potentially influencing the overall inflation profile [^].
Conversely, several factors could contribute to a lower Core CPI reading. Goldman Sachs projects a cooling in wage growth, which would alleviate inflationary pressures [^]. A moderation or decline in goods prices, particularly evident in categories like used cars and trucks, could also contribute to lower core inflation [^][^][^][^]. Furthermore, the aggressive interest rate hikes implemented by the Federal Reserve in previous periods have had a disinflationary effect, working to ease overall inflation [^]. A higher-than-expected Core CPI generally strengthens the U.S. Dollar (USD), while a lower reading typically weakens it [^].
