There are weeks when markets argue about everything, and there are weeks when everything comes down to two numbers. The week of October 29 was the second kind. On Thursday, October 29, the US Bureau of Economic Analysis released its advance estimate of third-quarter GDP and its September personal consumption expenditures (PCE) inflation report together, at 8:30am Eastern time — the first hard data since the Federal Reserve's October 28 decision, and the numbers that confirmed the market's big bet on a December rate hike.
Update — the actual numbers are in, and they landed on schedule. Despite the government shutdown scrambling much of America's data calendar, both October 29 prints arrived on time, and neither was delayed. Real GDP grew at a 3.4% annualised rate in the third quarter, beating the 3.2% Reuters consensus and accelerating from 2.2% in the second quarter. September headline PCE inflation rose to 3.6% year on year (up 0.5% on the month, from 3.4% in August), while core PCE rose to 3.1% year on year (up 0.3% on the month, from 3.0%). In other words, the test came back exactly as the hawks feared and hoped at once: strong growth, hot inflation.
The Setup: A Fed That Held, Divided
The Federal Reserve held its benchmark rate at 3.75%–4.00% on October 28, in a 10–2 vote — and the two dissenters wanted a hike, not a cut. That is the crucial detail. This was not a committee sitting comfortably on hold; it was a committee with a live hawkish minority arguing that inflation, pushed up by an energy shock tied to the Middle East conflict, demanded tighter policy.
Markets went into the October 29 data pricing roughly an 85% chance of a December hike, according to the trading desks tracked in the week's previews. That is an unusually strong conviction for a decision still six weeks away, and it explains why the GDP and PCE prints carried so much weight. A hike that is 85% priced in does not need good news to happen — it needs the absence of bad news. Any soft number gives the doves room to argue; any hot number hands the hawks their case.
What Was Expected: Growth Near 3%, Inflation Near 3.6%
On growth, the forecasts clustered around a strong quarter. Economists surveyed by Reuters expected GDP to have risen at a 3.2% annualised rate in the third quarter, up from 2.2% in the April–June period. FactSet's survey put it at 3.0%. The Federal Reserve Bank of Atlanta's GDPNow model was higher still, at 3.4%, while the New York Fed's nowcast was more cautious at 2.7%. Every one of those estimates pointed the same way: a clear acceleration from the second quarter, driven by resilient consumer spending and a surge in business investment tied to artificial intelligence.
The trade data added a wrinkle worth knowing. September's advance indicators showed the goods trade deficit widening, as strong demand for AI-related capital goods pushed imports to a record high. Economists estimated trade subtracted at least four percentage points from GDP growth in the quarter — which makes the expected 3%+ headline even more striking, because it implies domestic demand was powerful enough to absorb that drag and still accelerate.
On inflation, the consensus was less comfortable. Headline PCE for September was expected at about 3.6% year on year, with core PCE — excluding food and energy — at about 3.1%. Both are well above the Fed's 2% target. The September consumer price index, released earlier, had already shown prices rising 0.6% on the month and 3.7% on the year, the steepest pace in five months, driven by surging energy prices. PCE usually runs a little cooler than CPI, but nobody expected it to look cool.
What the Actual Numbers Showed
Real GDP grew 3.4% annualised in the third quarter, matching the Atlanta Fed GDPNow model and beating the New York Fed's 2.7% nowcast. The Bureau of Economic Analysis traced the gain to investment, consumer spending and government spending, partly offset by lower exports, while imports rose. Current-dollar GDP rose 5.6%, and real final sales to private domestic purchasers rose 4.9%, up from 4.6%.
Third-quarter PCE prices cooled to 2.1% annualised, with core at 2.5%, but September itself was hotter: headline PCE rose 0.5% on the month and core rose 0.3%. Personal income rose 0.2%, real spending was essentially flat, real disposable income fell 0.3%, and the saving rate was 3.8%. The December hike bet survived the data and leans hawkish.
The Four Scenarios That Decide December
This is where the data becomes a decision tree, and it is the part worth reading slowly.
Read it now as a scorecard: the first scenario is the one that actually happened.
Strong growth, hot inflation — this is what happened. GDP printed 3.4% and PCE printed 3.6% headline and 3.1% core, making the December hike the market's base case. The hawks got both halves of their argument: the economy can take it, and inflation demands it.
Strong growth, soft inflation. This is the Goldilocks outcome, and the one the White House would most like to see days before the midterms. Growth near 3% with PCE cooling toward 3% would let the Fed argue it can wait, and December hike odds would fall sharply. It is also the least likely combination given the energy-driven CPI print that preceded it.
Weak growth, hot inflation. This is the stagflation scare, and it is the outcome that frightens markets most. If growth disappoints — say, below 2.5% — while inflation stays near 3.6%, the Fed faces the worst of both worlds: hiking into weakness or tolerating inflation. Expect volatility, not a clean direction, and expect the December debate to turn ugly.
Weak growth, soft inflation. If both numbers disappoint, the hike bet collapses. The Fed's doves gain the upper hand, markets start pricing a longer hold, and the conversation shifts from "when is the next hike" to "did the Fed already go too far." Given the strength of the forecasts, this was the tail scenario — but tails have a habit of arriving in shutdown-disrupted data cycles.
The Data Blackout Nobody Is Pricing Properly
There is a second story hiding inside this one, and it may be the more important one. The government shutdown had already delayed or cancelled a string of federal releases before October 29, leaving traders, businesses and the Fed itself flying partly blind. The October payroll report, housing data and several other releases were caught in the backlog, and statistical agencies were working through a queue that would take weeks to clear.
That matters for two reasons. First, a single GDP or PCE print landing in a data vacuum carries more weight than it should, because there is less surrounding evidence to cross-check it against. Markets overreact to lonely numbers. Second, the October 29 prints did land on time, but the surrounding backlog remains, so the December decision still rests on thinner evidence, forced to lean on private surveys, regional Fed models and anecdote. Monetary policy made on anecdote is how mistakes happen.
The shutdown also explains why the GDPNow and nowcast models diverged as much as they did — 3.4% versus 2.7% is a wide gap for models looking at the same economy. When official data stops flowing, models lean on different private proxies, and their answers drift apart. The October 29 prints settled the GDPNow-vs-nowcast argument in favour of the optimists. The next checkpoint is November 25, when the BEA releases its second Q3 GDP estimate and October PCE.
What It Means for India
A December hike in the US is not an American story. It strengthens the dollar, and a stronger dollar has already been part of the rupee's painful autumn — the currency has been under sustained pressure, India's reserves have been drawn down defending it, and foreign investors have been net sellers of Indian equities through October.
Higher US rates also raise the bar for the Reserve Bank of India. If the Fed hikes in December, the RBI faces a harder choice between supporting growth and defending the currency, and Indian borrowers feel it through bond yields and, eventually, loan rates. Conversely, if the October 29 data had cooled the hike bet, some of that pressure would have eased — which is why traders in Mumbai were watching a Washington data release as closely as traders on Wall Street.
The Bottom Line
The test now has an answer: 3.4% growth, 3.6% headline inflation and 3.1% core inflation — the strong-growth, hot-inflation scenario that locks in the December hike as the base case. Flat real spending in September is the doves' remaining second-order argument, but it does not overturn the headline verdict.
The prints also proved the measurement system still worked, by arriving on time in a shutdown week, ahead of the December 8-9 FOMC meeting.
Frequently Asked Questions
What were the October 29 GDP and PCE releases?
The Bureau of Economic Analysis released its advance estimate of third-quarter GDP and its September PCE inflation report together on October 29, 2026, at 8:30am Eastern time, on schedule — the first major data since the Fed's October 28 hold. Actual figures: GDP 3.4% annualised, headline PCE 3.6% year on year (+0.5% month on month), and core PCE 3.1% year on year (+0.3% month on month).
What did forecasters expect?
GDP beat expectations: it printed 3.4% annualised, above the 3.2% Reuters consensus (FactSet expected 3.0%), matching the Atlanta Fed's GDPNow model and beating the New York Fed's 2.7% nowcast. Inflation matched expectations almost exactly: headline PCE 3.6% year on year and core PCE 3.1% year on year, as expected.
What did the Fed do on October 28?
It held rates at 3.75%–4.00% in a 10–2 vote, with the two dissenters favouring a hike. Markets went into the October 29 data pricing roughly an 85% chance of a December hike.
Why did the shutdown matter for this data?
The shutdown had already delayed or cancelled several federal releases, leaving gaps in the data the Fed relies on. The October 29 prints arrived on time, though the surrounding backlog remains, so the December decision still rests on thinner evidence.
How does a US rate hike affect India?
It tends to strengthen the dollar, which pressures the rupee, raises the cost of defending the currency, and makes the RBI's choice between supporting growth and stabilising the exchange rate harder. Indian bond yields and borrowing costs feel the knock-on effect.

My Personal Take
I find the whole setup slightly absurd, and I mean that seriously: the world's most important central bank went into the most consequential decision of its year with an 85% market conviction built on forecasts, because the actual data system had been knocked sideways by a shutdown. We treat economic numbers as if they arrive by physics. They arrive by civil servants, and when the civil servants are sent home, the market just guesses louder.
My own read is that the hike was more likely than not, but the certainty was fake. Strong growth plus sticky inflation is a hiking recipe, yes — but a Fed that hikes on a thin data file is a Fed that can be forced into an embarrassing reversal. And reversals, not hikes, are what actually break markets.
The October 29 numbers arrived on time and vindicated the loudest guess (3.4% growth, 3.6% inflation), and flat real spending in September is the detail that could come back to haunt a hike.
