GDP Beats at 3.4% While Core PCE Matches: A Run Sheet for a Double US Release

Key takeaways

1. US real GDP grew at a 3.4% annual rate in the third quarter, above the 3.2% consensus and the 2.4% and 2.5% forecasts of RBC and TD Securities (Bureau of Economic Analysis).

2. September core PCE prices rose 0.3% on the month and 3.1% on the year, in line with forecasts, while headline PCE inflation rose to 3.6% (Bureau of Economic Analysis).

3. With the top-ranked inflation figures in line, the rate reaction was modest: the two-year yield was 4.693% and December hike odds were 83%, from 78% in Asia (CNBC; CME FedWatch).

The development

The US Bureau of Economic Analysis (BEA) released the advance estimate of third-quarter GDP and the September Personal Income and Outlays report at 12:30 UTC (Bureau of Economic Analysis). Real GDP grew at a 3.4% annual rate after 2.2% in the second quarter. That was above the 3.2% calendar consensus (Forex Factory listing; Investing.com) and well above the 2.4% and 2.5% forecast by RBC Economics and TD Securities.

Inflation landed in line. The PCE price index rose 0.5% in September and 3.6% from a year earlier; excluding food and energy it rose 0.3% on the month and 3.1% on the year (Bureau of Economic Analysis). Core matched the 0.3% monthly consensus and the 3.1% annual forecasts of RBC and TD; headline matched TD's 3.6% and was below RBC's 3.7%. Real personal spending was flat, against RBC's forecast of a 0.1% rise. For the quarter, core PCE prices rose at a 2.5% annual rate. Initial jobless claims were 194,000 against a 198,000 consensus (US Department of Labor; Forex Factory listing).

Market transmission

After the data the two-year Treasury yield was 4.693%, 3 basis points lower on the day, and the ten-year was 5.011% (CNBC). Markets priced an 83% chance of a December Fed hike, compared with 78% in Asian trade (CME FedWatch via CNBC and Reuters). The pattern fits the ranking below: the inflation figures that rank first were in line, so the rate reaction stayed modest despite a clear growth beat.

The run sheet in five steps

1. Before 12:00 UTC: fix the reference points. Record consensus, the forecast range and the prior for each headline. Today's 3.4% growth print beat the 3.2% consensus and both bank forecasts.

2. Rank the figures by policy relevance. For a central bank worried about inflation, monthly core PCE ranks first, then the annual rate, then real spending, then GDP. Core at 0.3% matched consensus, which limited the signal from the growth surprise.

3. 12:30 UTC: read before reacting. Spreads in major pairs widen and liquidity thins for the first minutes. Many desks reduce position size into the release rather than guess its direction.

4. 12:31–12:45 UTC: check the transmission chain. Confirm that the two-year yield and fed funds futures moved in the same direction as the dollar. A dollar move without a rate move is often positioning and can fade.

5. 12:45–13:15 UTC: reset before the next event. The ECB decision can overwrite the US reaction in EURUSD. Record December hike probability and the two-year yield before the second event; the ECB held at 13:15 UTC (European Central Bank).

What to monitor next

• Revisions: the BEA updated July and August personal income with revised payroll data, and the second GDP estimate is due on 25 November.

• Fed speakers from Friday, when the post-meeting blackout ends (Thornburg Investment Management via CNBC).

• December hike pricing, near 83% after the release (CME FedWatch via CNBC).

Reusable lesson

A combined release rewards preparation more than speed. Write down beforehand which figure ranks first, what counts as a surprise against both consensus and the range of serious forecasts, and which rate market must confirm the currency move. Today showed why the ranking matters: a large growth beat with in-line core inflation produced only a modest rate reaction.

Invalidation and risk

The framework assumes inflation dominates the Fed's reaction function. If growth stays this strong, markets may weight GDP more heavily over time. The advance estimate will be revised twice; the figures here are taken from the BEA releases.
