Our call sits −0.10pp versus the Street; the Gauge runs −0.43pp versus the July 2026 print of 3.4% that this release replaces. The forecast is a separate product from the Gauge — the Gauge measures today's prices; the forecast is the pre-registered call for what the BLS will print, graded after every release (August 2026 preview and grading).

Method

The Nowflation Gauge is a measurement of today’s prices — live market sources for the components that have them (all-tenant rents measured from this month’s new leases, pump prices, used-vehicle auctions) and the latest BLS subindex, held as measured, for the rest. It is never a forecast. The print-day call is a separate product: the Nowflation Forecast is the pre-registered ensemble for the next CPI release (locked the evening before, graded after); the in-house model is shown alongside it. The wire paragraph is written by Claude from the day’s engine figures only (model alias in each record; a deterministic template when the API is unavailable). The “what moved” bullets are computed, not written. recomputed 8:40 AM & 6 PM ET · published 9 AM ET · 8:45 AM ET on print days. Methodology · every input, exposed · calendar feed, RSS and email.
