A running estimate of real GDP growth using incoming monthly releases and transparent component contributions.
The GDP Dynamics nowcast for third-quarter US real GDP growth remained unchanged at 3.4% annualized on October 28, with no revisions to the estimated contributions from the major expenditure components. The forecast is equivalent to approximately 0.8% growth on a nonannualized quarter-over-quarter basis.
The latest update incorporated available information from crude oil markets, financial conditions and Treasury yields, but none of the indicators produced a measurable change in the headline estimate. With the advance GDP release approaching, the model continues to point toward relatively strong economic growth during the third quarter.
The nowcast has held at 3.4% since the previous update on October 27. The latest snapshot includes Brent crude oil, West Texas Intermediate crude oil, the Financial Conditions Index and the 10-year Treasury yield.
These indicators provide information about the financial and economic environment rather than direct measurements of quarterly GDP expenditure. Oil prices can influence production costs, inflation and household purchasing power, while Treasury yields and broader financial conditions affect borrowing costs and investment incentives.
Although these channels are relevant to the economic outlook, the latest model update produced no change in the estimated growth rate. The available snapshot does not establish whether the individual indicators rose or fell, so it would be premature to attribute the unchanged forecast to offsetting movements in financial markets.
The stability of the headline estimate also extends to the model's expenditure contributions, which remain unchanged from the October 27 update.
Consumer spending is currently estimated to contribute 2.8 percentage points to annualized GDP growth. This reflects the importance of household expenditure within the American economy, although the latest update provides no new evidence of an acceleration or deceleration in consumption.
Business fixed investment contributes another 1.2 percentage points, indicating a substantial positive contribution from investment in productive assets. Inventories add an estimated 0.5 percentage points, while government expenditure contributes 0.2 percentage points.
Residential investment is approximately neutral, contributing 0.0 percentage points to the current estimate.
These figures describe the estimated composition of third-quarter growth rather than changes occurring on October 28. None of these expenditure components registered a contribution revision in the latest update.
The external sector remains the principal negative contribution in the current expenditure breakdown, with net exports subtracting approximately 1.4 percentage points from annualized real GDP growth.
A negative net export contribution can arise from stronger import growth, weaker export growth or a combination of the two. The current snapshot does not provide enough information to determine which of these developments accounts for the estimated drag.
The negative contribution is nevertheless significant. Domestic expenditure components collectively provide positive contributions to growth, while the external sector offsets part of that expansion.
The contribution estimates are rounded, so their reported sum should not be treated as an exact reconstruction of the headline forecast.
With the model holding at 3.4%, attention now turns to the advance estimate of third-quarter GDP from the Bureau of Economic Analysis.
The release will provide the first official assessment of the quarter's real economic growth and a more complete breakdown of consumption, investment, government expenditure and international trade.
Particular attention will be paid to whether the official data confirm the model's positive estimates for consumer spending and business fixed investment, along with the negative contribution from net exports.
The advance GDP estimate will also provide an opportunity to evaluate the accuracy of the GDP Dynamics nowcast against the initial official reading. As with any advance GDP estimate, subsequent revisions may change the reported growth rate and its composition.
For now, the GDP Dynamics model continues to estimate 3.4% annualized real GDP growth in Q3 2026, unchanged from October 27.
