NEW YORK, April 10, 2026. The Bureau of Labor Statistics released the March Consumer Price Index at 8:30 AM ET this morning — the first inflation data point to fully capture the period following the Iran war’s February 28 outbreak and the subsequent closure of the Strait of Hormuz. The Wall Street consensus, compiled across FactSet, Bloomberg, Morningstar, and individual bank forecasts, is unambiguous: headline CPI is expected to show a monthly increase of approximately +0.9% — the largest single-month gain since June 2022, at the peak of the post-pandemic inflation surge — driven almost entirely by energy prices that rose an estimated +10.6% month-over-month as gasoline crossed $4 per gallon nationally for the first time in years. The year-over-year rate is expected to jump from February’s 2.4% to somewhere between 3.3% and 3.7%, depending on whose model you use. Core CPI (excluding food and energy) is expected to show a more moderate +0.2% to +0.3% MoM, with the YoY core rate rising from 2.5% to approximately 2.7–3.0%. At 10:00 AM ET, the University of Michigan will release its preliminary April consumer sentiment reading — expected to decline further from March’s 53.3, though the ceasefire announced Tuesday may produce a partial bounce from the survey’s multi-year lows.
Why this is the most consequential CPI print since 2022
The March 2026 CPI is not just another monthly inflation data point — it is the first quantitative reckoning with the largest single-month energy price shock the United States has experienced since at least 1957, according to Pantheon Economics. The Strait of Hormuz closed on or around March 4 as Iran’s naval response to the U.S.-Israeli strikes of February 28. Within the March survey period, gasoline prices rose approximately $1 per gallon nationally — from approximately $2.98 in late February to above $4.00 by mid-March — representing the kind of household budget shock that American consumers had not experienced since the 2022 post-pandemic inflation peak. Consumers have already paid an estimated $8.4 billion in additional fuel costs in the first month since the war started, according to the Joint Economic Committee. Those costs are reflected in today’s data.
The critical analytical distinction in today’s print is between the headline and the core. A +0.9% monthly headline driven almost entirely by energy — with BofA Securities projecting a +10.6% MoM jump in the energy sub-index — is in one sense the expected mechanical read-through of an oil price shock. The Federal Reserve has historically treated energy-driven spikes as transitory, looking through them to core inflation as the better guide to underlying monetary policy. But the March core reading will be closely scrutinised for evidence that energy costs are beginning to diffuse into the wider price complex: transportation services (where higher fuel feeds directly into airline ticket pricing, which the Bureau of Transportation Statistics was already tracking at elevated levels heading into March), food prices (where freight and distribution costs are sensitive to fuel), and shelter (where the existing trend of sticky owner-equivalent rent remains a structural floor for core inflation above 2.5%). If the core print comes in at the high end of the range — +0.3% MoM or above — it would suggest the Iran war’s inflation is beginning to spread beyond the pump, and the Fed’s “look through the energy spike” calculus becomes materially more difficult to defend. For investors tracking how the Fed weighs CPI versus PCE, the March print is the most informative single data point on that question that the current conflict has produced.
The three scenarios — what each outcome means for the Fed and markets
Scenario A: In-line (+0.8–0.9% MoM, +3.3–3.7% YoY; Core +0.2–0.3%). The expected outcome confirms the mechanical energy transmission without showing broad diffusion into core. The Fed maintains its hold posture comfortably — the data validates the “transitory energy spike” framing — while the hawkish pivot in Wednesday’s FOMC minutes provides forward-looking cover for a rate hike if the conflict extends and inflation expectations become unanchored. Equity markets would likely absorb an in-line print without significant directional movement: the number is already priced into positioning, and the ceasefire relief from Wednesday provides a structural offset to any macro bearishness. Treasury yields would hold near current levels, with the 2-year and 10-year reflecting existing “higher for longer, no immediate hike” pricing. This is the most likely single scenario and the least market-moving.
Scenario B: Below consensus (+0.6–0.7% MoM, +3.0–3.2% YoY; Core +0.1–0.2%). A meaningful beat for consumers and markets. An energy contribution lower than the +10.6% BofA projection — possible if the timing of gasoline price spikes fell slightly outside the March survey’s reference period — would allow the Fed to maintain its dovish-hold framing with confidence and potentially restart conversations about the September rate cut pathway. Treasury yields would fall, rate-sensitive equities (homebuilders, utilities, REITs) would rally, and the S&P 500 could see a genuine relief surge that builds on the ceasefire-driven Wednesday gains. The Cleveland Fed’s nowcast projection of +3.16% YoY makes this the “goldilocks” scenario — hot enough to confirm the Iran war’s economic impact is real, cool enough that it doesn’t force a hawkish policy response before the fog lifts.
Scenario C: Above consensus (+1.0%+ MoM, +3.8–4.0%+ YoY; Core +0.3–0.4%). Oxford Economics had pre-released a forecast of CPI “well above 3% in March and above 4% by April,” implying that even March could reach 4%. A print above 3.8% YoY — particularly if accompanied by a hot core reading above 0.3% — would confirm that the Iran war’s energy shock is diffusing rapidly into the wider price complex and would be the clearest single data point in support of the FOMC hawks who have been arguing for rate hike optionality. Brean Capital’s John Ryding explicitly flagged Thursday’s ISM Services Prices Paid reading of 70.7 as “consistent with inflation running close to 4%.” An above-consensus CPI print this morning would be the corroborating data point that the hawkish wing needs to force a policy debate ahead of April 28–29. Treasury yields would surge, growth stocks would sell off, and a VIX already above 25 would push toward 30. This is the scenario the market is most anxious about and least positioned for.
The “rockets and feathers” problem — why the ceasefire doesn’t solve March’s print
The two-week US-Iran ceasefire announced Tuesday evening has created a specific analytical trap for investors reading today’s CPI: the temptation to assume that Wednesday’s 16.41% crude oil crash means the inflation problem is resolving. It does not — at least not in time to affect the March data. The CPI reference period for March uses price data collected primarily in the first three weeks of the month, when gasoline was at or above $4 per gallon and crude oil was approaching $110–115 per barrel. The ceasefire’s oil price relief arrived on April 7–8, three weeks after the March survey closed. Everything the ceasefire has done to crude prices is a potential April story, not a March story.
The “rockets and feathers” phenomenon that CBS News and multiple economists cited ahead of this release adds a further complication: energy prices tend to spike rapidly during supply disruptions but fall slowly after a crisis ends. Even if the ceasefire holds and Hormuz throughput normalises during the two-week window, the pass-through of lower crude prices to retail gasoline typically takes 6–12 weeks, meaning $4+ gasoline at the pump may persist through May or June regardless of what crude does from here. That dynamics means today’s March CPI print is the floor — not the peak — of the war-driven inflation surge. Oxford Economics’ forecast of CPI “above 4% by April” anticipates exactly this: that the March print shows the first-month spike and April’s data, which will be collected while gasoline remains elevated, confirms a second month of elevated readings before any ceasefire relief reaches the pump. For the Federal Reserve, that sequential two-month inflation picture is precisely the “persistent” inflation signal that the March FOMC minutes flagged as the risk requiring a more hawkish posture.
University of Michigan April preliminary sentiment — a ceasefire bounce test at 10 AM
At 10:00 AM ET, the University of Michigan releases its preliminary April consumer sentiment reading. March’s final reading of 53.3 — the bottom 1st percentile of the survey’s 75-year history and below the starting level of every U.S. recession since 1978 — was collected primarily between mid-February and late March, with approximately two-thirds of the responses coming after the war began. The April preliminary survey will be the first full sentiment reading conducted after the war’s onset, and its field period will have overlapped with both the Kharg Island strikes (Tuesday) and the ceasefire announcement (also Tuesday). That sequencing creates a specific question: did the ceasefire announcement produce a measurable upward jump in sentiment responses collected after Tuesday evening? If so, the preliminary April reading may come in above the gloomy consensus of a continued decline, providing a second positive signal alongside the ceasefire relief rally’s equity market implications.
The expectation heading into the April survey was for further deterioration from 53.3, driven by gasoline at $4+/gallon and ongoing war anxiety. March’s final reading already incorporated the survey director’s observation that “consumers with middle and higher incomes and stock wealth, buffeted by both escalating gas prices and volatile financial markets, exhibited particularly large drops in sentiment” — the demographic that most directly influences consumer spending on discretionary goods, travel, and home improvement. A ceasefire-driven partial recovery in the April preliminary could signal that the consumer spending pressure most feared by retailers, airlines, and consumer discretionary companies is at least plateauing. One-year inflation expectations, which jumped to 3.8% in March (the largest monthly increase since April 2025), will be closely watched alongside the headline. If expectations remain elevated despite the ceasefire, it suggests consumers don’t believe the war’s inflation consequences are temporary — a signal the Fed cannot ignore.

What this means for April 28–29 and the rest of 2026
The April 28–29 FOMC meeting is the next formal policy checkpoint, and today’s CPI substantially shapes its analytical context. The Fed enters pre-meeting communications blackout on April 23, meaning officials have approximately two weeks from today to make their last public statements before the meeting. CME FedWatch currently prices a 98.4% probability of a hold at 3.50–3.75%. The FOMC minutes released Wednesday confirmed that the hold is well supported internally — the “vast majority of participants” judged that inflation risk has increased, and seven of 19 members now project zero cuts in 2026. What Wednesday’s minutes did not do is explicitly put a rate hike on the April table. For a hike to become live at April 28–29, it would require a CPI print today that was materially above consensus plus a continued deterioration in inflation expectations that broke the ceasefire-driven market narrative. That combination is possible but unlikely as the base case — the ceasefire is providing enough near-term relief to keep the Committee’s “prudent patience” framing intact for at least one more meeting.
The more significant policy inflection point is June 16–17 — two FOMC meetings away. By June, the Fed will have the March PCE (April 30), April CPI (May 13), April PCE (May 29), and a fuller picture of ceasefire durability and Hormuz reopening progress. If today’s March CPI confirms the expected 3.3–3.7% YoY range and the ceasefire holds through the two-week window with Hormuz genuinely reopening, the June meeting could mark the first policy pivot in either direction — toward a cut (if fuel prices retreat and inflation expectations fall back below 3%) or toward a hike (if the ceasefire fractures and oil re-spikes, making April’s CPI as hot as Oxford Economics projects). The tariff offset partially softens the picture: the effective U.S. tariff rate has fallen from a 2025 peak of 21% to approximately 8%, reducing one inflationary input while the war adds another. For investors, the practical implication is to monitor today’s core CPI reading above all other sub-components — it is the data point that most directly answers the question of whether March 2026 is a one-month energy shock or the first data point in a new, more persistent inflation regime. The 10-year Treasury yield will be the fastest-moving real-time verdict on the print’s policy implications.
