• SPF expects 2.1% core growth
• Trade shocks not yet curbing core output

Pulse Analysis

Nowcasting has become a cornerstone of real‑time economic analysis, allowing policymakers and market participants to gauge growth before official releases. The Atlanta Fed’s GDPNow model incorporates the latest releases—retail sales, employment, and construction data—producing a 4% quarterly‑annualized estimate for Q2 2026. In contrast, the St. Louis Fed’s approach, which weights earlier data more heavily, signals a modest 0.8% expansion. This split underscores how model design and data timing can generate markedly different short‑term outlooks, prompting analysts to monitor multiple nowcasts for a fuller picture.

A complementary lens focuses on “core GDP,” measured by final sales to private domestic purchasers. This proxy strips out volatile government and net‑export components, offering a clearer view of domestic demand. The nowcasted core growth of 3.1% q/q annualized exceeds the Survey of Professional Forecasters’ 2.1% projection, suggesting that consumption and private investment remain resilient despite recent trade disruptions. Adjustments to align SPF components with BEA data further validate the robustness of this metric, positioning it as a reliable barometer for underlying economic momentum.

The divergence between headline GDP nowcasts and core GDP signals both opportunities and risks for decision‑makers. A higher GDPNow reading could embolden the Federal Reserve to maintain a tighter monetary stance, while the modest St. Louis forecast may encourage a more cautious approach. Investors watching earnings and corporate spending will likely weigh the stronger core signal as evidence that consumer demand is holding up, potentially supporting equity valuations. As the official Q2 advance estimate approaches, the interplay of these nowcasts will shape expectations for growth, inflation pressures, and policy direction.
