About our March 20026 CPI forecast

Despite all the noise caused by the temporary closure of the Strait of Hormuz, the Core CPI is falling and surprised to the downside--dovish data for the incoming Fed Chairman.

Core came in exactly where we forecast — +0.2% MoM, 10bp below consensus. The single-channel thesis held: this was a gasoline print, not a broad inflation print. Core is running at the same pace as February.

On headline, we were at +0.8%, BLS rounded to +0.9%. The unrounded actual was +0.86% — so the real gap was 6bp, not 10bp. Closer than it looks, but consensus got the rounded number right and we didn't.

The call that mattered most — that core would not accelerate despite the energy shock — was right. We'll take it.

XTech's Advanced CPI Forecasting Methodology

XTech's CPI forecasts are produced by a machine learning model trained on historical data, consumer survey data, and bespoke alternative datasets, using a one-step-ahead ("teacher forcing") technique that continuously recalibrates against the most recent actual release.

Two forecasts are published each month: the First Forecast (made available to clients ~20 days before the BLS release, before sell-side consensus forms; headline MoM correlation 87%, MAE 0.001) and the Second and Final Forecast (made available to clients ~5 days before, with more data inputs; correlation 88%, MAE 0.0009).

Both cover headline and core CPI (MoM/YoY); category-level forecasts are also available for Gasoline, Shelter, Food, Transportation, Medical, Used Cars, and others.

Approximate basket weights: Shelter 35% · Commodities 19% · Food 14% · Medical 7% · Transportation 6%. Gasoline is the model's highest-conviction category (correlation 96%); Used Cars & Trucks the most uncertain (correlation 73%).

Why XTech forecasts outperform consensus

Executive Thesis

March CPI confirmed the most energy-dominated inflation print in decades — headline surged 0.9% on a record 21.2% gasoline spike while core held at a benign 0.2%, the clearest headline/core bifurcation since 2022.

The ceasefire that was expected to deflate the energy premium has not cleanly resolved: oil has settled near $100, gasoline remains above $4/gal, and second-round effects are building in services prices, airfares, and inflation expectations.

The critical question for April is whether core can stay contained as the energy shock persists and its downstream effects accumulate.

1. Energy and Global Commodities

The March CPI energy index surged 10.9%, with gasoline's 21.2% MoM increase — the largest since the BLS series began in 1967 — accounting for nearly three-quarters of the headline gain.

But the April 7 ceasefire has not produced the clean price decline markets initially priced. After Brent plunged from ~$118 to ~$92 on the announcement, Iran accused the U.S. of breach (April 9), talks collapsed (April 12), and the U.S. Navy imposed a full blockade on Iranian ports.

As of April 16, Brent is back near $99, the Strait remains blocked, and retail gasoline stands at $4.12/gal — essentially flat from pre-ceasefire levels and up $0.96 YoY. The EIA's April STEO projects Brent peaking at $115 in Q2 but assumes the conflict ends in April, an assumption at risk as the April 21 ceasefire expiration approaches

CPI impact: Gasoline will again be a large positive headline contributor in April, though likely smaller than March's record. The ceasefire's failure to produce a meaningful pump price decline is the most important revision from Week 1.

2. Trade Policy and Tariffs

The tariff landscape is structurally unchanged from Week 1, but the March CPI offers a data point: apparel rose 1.0% MoM, consistent with ongoing tariff pass-through in import-sensitive categories.

The USTR's Section 301 hearings on probes into China, the EU, Japan, India, Taiwan, and 10+ other economies are now scheduled for April 28 – May 1 — a timeline trade attorneys describe as "unrealistically short." If the probes find violations, new tariffs could emerge in summer. Meanwhile, structural levies remain: China ~33.9%, steel/aluminum ~41.1%, autos 25%.

The SCOTUS IEEPA refund (~$175B) is still unresolved, partially offsetting Section 122 costs. Fed Vice Chair Jefferson singled out tariffs — not energy — as the primary reason inflation progress has "stalled," a framing that may shape how the Fed weighs the March headline surge.

CPI impact: Net tariff burden unchanged from March. The 25% auto tariff continues to drive demand substitution into used vehicles. Section 301 outcomes are a summer story, not an April CPI driver.

3. Labor Market and Wages

No new data released during April 1–16. March nonfarm payrolls (+178K, well above the +59K consensus) and the wage deceleration to +0.2% MoM / +3.5% YoY — the lowest annual rate since May 2021 — remain the operative signals, per the March employment report.

The payroll recovery (reversing February's revised -133K) was led by healthcare (+76K). Unemployment edged to 4.3%, though partly from labor force contraction. At +3.5% YoY, wages are approaching the ~3.0–3.5% range the Fed considers consistent with its 2% inflation target. The next Employment Cost Index reading (Q1 2026) will be the key update for this channel.

CPI impact: Wage deceleration remains the strongest disinflationary signal for core services. It partially offsets the energy pass-through now visible in ISM Services prices and airline fares, and supports the view that services inflation is not broadly accelerating despite the commodity shock.

4. Manufacturing, Logistics, and Supply Chain

The March PPI release delivered a meaningful downside surprise: producer prices rose just 0.5%, well below the 1.1% Dow Jones consensus, with core PPI (ex food and energy) at only +0.1% versus 0.5% expected. Energy PPI jumped 8.5% (gasoline +15.7%), mirroring the CPI pattern — the inflation is concentrated in energy, not broadening into the core pipeline

Crucially, PPI for final demand services was unchanged, providing a counterpoint to the ISM Services Prices reading of 70.7 — the highest since October 2022. ISM Manufacturing Prices remained at 78.3, with 17 of 18 industries reporting higher costs.

The divergence between survey-based ISM prices (elevated) and actual PPI services (flat) suggests that while businesses expect to pass costs through, the transmission into final prices has been slower than feared.

CPI impact: The PPI miss materially softens the goods inflation outlook. ISM surveys signal building pressure, but actual producer prices show the pass-through is incomplete — supporting the view that core can hold near 0.2% MoM for another month or two.

5. Shelter and Housing

March CPI confirmed the shelter deceleration trend: the shelter index rose 0.3% MoM and ~3.0% YoY — the slowest annual pace since August 2021. The most recent official data is the Census Bureau's Q4 2025 rental vacancy rate of 7.2%, statistically unchanged from Q3 2025 (7.1%) and Q4 2024 (6.9%).

Private-sector indicators from the March cycle remain operative: Apartment List's March national median rent rose just +0.4% MoM with year-over-year growth at −1.7% (a record low for the index), and apartment vacancy was at 7.3–7.4% per the Richmond Fed's multifamily data.

The well-documented 12–18 month lag between market rents and the OER/rent CPI measures means the elevated vacancy rate and negative market rent growth should continue feeding through as gradual shelter deceleration.

CPI impact: Shelter remains the clearest disinflationary force in CPI. The March +0.3% MoM reading is consistent with a steady glide lower. Expect a similar or slightly softer shelter contribution through mid-2026.

6. Food and Agriculture

March CPI food was flat at 0.0% MoM — better than the USDA's 3.6% annual forecast would imply on a monthly basis. Food at home fell 0.2%, likely reflecting egg price normalization and dairy deflation flagged in the USDA outlook, while food away from home rose 0.2%.

The USDA's latest food price forecast is unchanged: all-food CPI forecast at 3.6% for 2026 (interval 1.6–5.6%), with beef/veal at +10.1% and 8 of 15 food-at-home categories growing faster than their 20-year average.

The fertilizer supply channel (nitrogen +30% since Hormuz closure; Qatar's QAFCO offline at ~5.5M tons/year) remains the key upside risk, but the ceasefire — however fragile — has prevented further escalation. Next USDA revision: April 24

CPI impact: Near-term food pressure is softer than forecast. The flat March reading suggests the 3.6% annual target may prove slightly high if energy costs stabilize. The fertilizer channel is a Q3–Q4 story.

7. Services Inflation and Fed Signaling

The tension between survey-based and actual price data is the defining feature of this section. ISM Services Prices at 70.7 — the highest since October 2022 — signals significant cost pressure, but March PPI services was unchanged and core CPI (+0.2%) showed no broadening.

Meanwhile, Michigan one-year inflation expectations jumped to 4.8% (+1pp), with consumer sentiment falling to a record low of 47.6 — driven by gasoline sticker shock.

Fed Vice Chair Jefferson's April 7 speech reinforced the steady posture: rates at 3.5–3.75% are "appropriately positioned," inflation has been stalled by tariffs, and the labor market shows a "low-hire, low-fire" dynamic. The next FOMC meeting is April 28–29.

CPI impact: The Fed is not providing a monetary offset. The key risk is whether ISM price intentions and elevated expectations will translate into actual services price acceleration in April–May. March data says not yet — but the lag is the concern.

8. High-Volatility CPI Components

Used vehicles: The March CPI resolved the Manheim puzzle — used cars and trucks fell 0.4% MoM despite the 6.2% YoY wholesale surge reported by Cox Automotive. The wholesale-to-retail transmission lag (1–2 months) means the Manheim signal is an April/May CPI story, not March. Cox raised its 2026 used vehicle sales forecast to 20.4M units, and retail list prices for three-year-old vehicles are running ~2% above year-ago levels. The 25% tariff on new imports continues to push buyers into the used market.

Airfares: March CPI confirmed airfares running +14.9% YoY. A deepening jet fuel supply crunch is compounding the picture: SAS canceled 1,000 April flights, Ryanair is cutting summer capacity, and U.S. lawmakers are pressuring carriers to lower fares. But reduced capacity supports pricing power even if crude eases. Fares booked at elevated prices are locked into BLS sampling.

Motor vehicle insurance: Unchanged in March (0.0% MoM / +5.9% YoY).

CPI impact: Used vehicles are the swing factor for April core — if even a fraction of the 6.2% wholesale surge transmits, it could add 1–2bp to core MoM. Airfares will remain a positive contributor until jet fuel normalizes, which airline CEOs say will take months.
