First print for 2026-07 captured from https://alfred.stlouisfed.org/graph/alfredgraph.csv?id=TTLCONS&vintage_date=2026-09-01 on the official release date named by the cell's resolver.

Analysis

§July 2026 U.S. construction spending MoM first print

Framing and exact resolver: the target is the U.S. Census Bureau Value of Construction Put in Place Survey total construction series, seasonally adjusted annual rate, for July 2026. The canonical ledger binds resolution to ALFRED TTLCONS first_print even though Census is the official agency source; I use Census pages for schedule and release context, and keep the resolver tied to the registered ALFRED TTLCONS first-vintage rule.

▸ Reported tool use: official.lookupmodel report
Census Construction Spending release schedule lookup for the July 2026 reporting period
↳ Fetched schedule says Monthly Value of Construction Put in Place July releases on September 1, 2026 at 10:00 a.m.; June releases on August 3, 2026 and August releases on October 1, 2026.
▸ Reported tool use: official.lookupmodel report
Census current Construction Spending release lookup for the latest official context
↳ Fetched May 2026 release: total construction spending was $2,210.2 billion SAAR, 0.1 percent above revised April $2,207.1 billion, and 1.5 percent below May 2025 $2,244.4 billion.
▸ Reported tool use: official.lookupmodel report
FRED/Census MPCTXXXXS percent-change series lookup for recent monthly values
↳ Fetched MPCTXXXXS values: May 2026 0.1, Apr 2026 0.3, Mar 2026 0.4, Feb 2026 -0.3, Jan 2026 -0.9 percent change from preceding period, seasonally adjusted.
▸ Reported tool use: official.lookupmodel report
FRED release table lookup for total construction levels behind the percent-change target
↳ Fetched release table levels: total construction May 2026 2,210,214 million dollars, Apr 2026 2,207,051 million dollars, May 2025 2,244,426 million dollars.

The release variant is total construction, seasonally adjusted annual rate, converted to month-over-month percent growth. The target is first print for July 2026, so later revisions to June or July should not be used when resolving.

Reference class and base rate: recent monthly percent changes in total construction spending are centered close to zero. The volatility sample uses current revised public MPCTXXXXS values available before the run, not ALFRED first-vintage values, because it is an uncertainty reference class rather than the resolution source. The 2024-08 through 2026-05 sequence was 0.2, -0.3, 0.0, -0.2, -0.7, -0.3, -0.2, -0.7, 0.1, -0.2, 0.5, 0.4, 0.4, -0.4, -0.1, 0.6, 1.8, -1.9, -0.8, 0.2, 0.4, 0.1, giving a near-zero mean around -0.05 percentage point.

Level, momentum, one-off, and policy-mechanism effects: the latest Census release shows nominal total spending barely positive, public construction positive, private residential positive, and private nonresidential soft. I do not see a clear one-off mechanism that should dominate the base rate by July; July is therefore anchored near flat rather than extrapolating the revised January drop or the December spike.

Prior/update/interval: persistence/base-rate prior is a rolling recent-history prior near 0.0 from the recent MPCTXXXXS reference class, with no separate AR or structural model. I apply a small positive update from May total spending at +0.1 percent, private residential +0.3 percent, and public construction +0.5 percent, offset by private nonresidential -0.3 percent. I set point = 0.1. For the 22 recent percent-change observations listed above, mean is about -0.05 and sample sigma = 0.69 percentage point; 1.28*sigma = 0.88 percentage point, so an 80% interval around 0.1 is roughly -0.8 to 1.0 after rounding.

Counter-considerations: upside risk is a rebound in manufacturing, data centers, public infrastructure, or residential improvements that would land above the interval if July prints above 1.0 percent. Downside risk is a renewed private nonresidential/manufacturing pullback or sharper residential decline that would land below the interval if July prints below -0.8 percent.

Review disposition: accepted the reviewer suggestions to clarify that the volatility sample uses current revised MPCTXXXXS values rather than first-vintage values, and to state explicitly that the time-series prior is a rolling recent-history/persistence prior with no separate AR or structural model; no required fixes were identified.

Key drivers

  • recent total construction spending is near flat
  • private residential was positive in May
  • private nonresidential and manufacturing remain drags
  • public construction was positive in May
  • monthly construction spending changes have wide revision-prone dispersion

Tool evidence

This run has no captured tool responses. “Reported tool use” in the analysis is the model’s account, not an archived tool response.

Sources and resolution

Official source
U.S. Census Bureau Construction Spending release, mirrored through the registered ALFRED TTLCONS first-vintage binding
Resolved
September 3, 2026
Resolution rule
Resolve to the first official print for July 2026 total construction spending, seasonally adjusted annual rate, as the percent change from June 2026 to July 2026 implied by TTLCONS in the registered ALFRED first-vintage source. Use the first posted vintage only; do not incorporate later Census/FRED/ALFRED revisions or same-day corrections unless they are part of the initially posted release vintage. Round to one decimal percentage point, matching the Census/FRED percent-change display convention.
