GDP Grows 3.4% in the Third Quarter, but September’s 3.6% PCE Inflation Keeps the Fed in a Bind

The U.S. economy grew at a 3.4% annual rate in the third quarter, while the PCE price index rose 3.6% from a year earlier in September and real consumer spending was flat on the month.

Thursday morning’s data gave both sides of the Fed debate something to point to. The economy grew faster in the third quarter than in the second, which supports the Fed’s new description of a strong expansion. But the Fed’s preferred inflation gauge rose 3.6% from a year earlier in September, and households barely increased their spending in real terms. Coming the day after two policymakers voted for a rate hike, I read the mix as keeping that option firmly on the table.

Growth Accelerates to 3.4%

According to the Bureau of Economic Analysis advance estimate, real GDP grew at a 3.4% annual rate in the third quarter, up from 2.2% in the second. Investment, consumer spending and government spending all contributed, partly offset by a drop in exports, while imports rose. The acceleration mainly reflected faster investment and an upturn in government spending. Real final sales to private domestic purchasers, which strip out trade, inventories and government and are a good read on underlying private demand, rose 4.9% after 4.6%.

The quarterly inflation readings in the GDP report looked benign: the PCE price index rose at a 2.1% annual rate in the third quarter and 2.5% excluding food and energy, down from 5.0% and 3.3% in the second quarter. Those are quarter-over-quarter annualized rates, though, and the monthly report released at the same time tells a less comfortable story about where the quarter ended.

September Ended the Quarter Hot

The September personal income and outlays report shows the PCE price index up 0.5% on the month and 3.6% from a year earlier. Excluding food and energy, prices rose 0.3% on the month and 3.1% over twelve months. That lines up with the 3.7% consumer price inflation reported for September, where gasoline drove more than half of the monthly increase.

The household picture is the weak spot. Nominal consumer spending rose 0.5% in September, but after inflation real spending was essentially flat, and real disposable income fell 0.3%. The personal saving rate stood at 3.8%. Put simply, higher prices absorbed September’s income gains, which is the kind of squeeze that can slow consumption later even when the quarterly GDP figure looks strong.

What It Means After Wednesday’s Fed Meeting

On Wednesday the Federal Reserve held its target range at 3.75% to 4%, with Lisa Cook and Beth Hammack dissenting in favor of a quarter-point hike, and upgraded its description of growth from solid to strong. Thursday’s numbers confirm that assessment of growth and show inflation still well above the 2% goal. Bond markets took the data calmly: the 10-year Treasury yield slipped to just under 5% by early afternoon, based on Yahoo Finance data. The next GDP estimate and the October income and spending report are both scheduled for Nov. 25.
