Inventories, trade shield U.S. economy from hurricane headwinds

By Lucia Mutikani

WASHINGTON (Reuters) - The U.S. economy unexpectedly maintained a brisk pace of growth in the third quarter as an increase in inventory investment and a smaller trade deficit offset a hurricane-related slowdown in consumer spending and a decline in construction.

Gross domestic product increased at a 3.0 percent annual rate in the July-September period, also supported by strong business spending on equipment, the Commerce Department said on Friday. With inventories, goods yet to be sold, contributing almost three-quarters of a percentage point to growth last quarter, the increase in GDP overstates the economy's health.

Excluding inventory investment, the economy grew at a 2.3 percent rate, slowing from the second quarter's 2.9 percent pace. A measure of domestic demand also decelerated to a 2.2 percent growth rate from the April-June period's 3.3 percent pace.

"This is a positive report for an economy that was battered by two hurricanes late in the quarter but it is not as strong as the headline 3.0 percent growth might suggest," said John Ryding, chief economist at RDQ Economics in New York.

The economy grew at a 3.1 percent pace in the second quarter. It was the first time since 2014 that it experienced growth of 3 percent or more for two quarters in a row. Economists had forecast GDP increasing at a 2.5 percent rate in the third quarter.

The government said while it was impossible to estimate the overall impact of hurricanes Harvey and Irma on third-quarter GDP, preliminary estimates showed that the back-to-back storms had caused losses of $121.0 billion in privately owned fixed assets and $10.4 billion in government-owned fixed assets.

Harvey and Irma struck parts of Texas and Florida in late August and early September. Hurricane Maria, which destroyed infrastructure in Puerto Rico and the Virgin Islands, had no impact on third-quarter GDP growth as the islands are not included in the United States' national accounts.

Post-hurricane labor market, retail sales and industrial production data already show an acceleration in underlying economic activity. Economists expect the Federal Reserve will increase interest rates for a third time this year in December.

"Fed officials will be encouraged by both the overall performance and the composition of growth in the third quarter, which confirms the U.S. economic expansion remains on solid ground," said Michelle Girard, chief U.S. economist at NatWest Markets in Stamford, Connecticut.

The dollar rose to a three-month high against a basket of currencies on the data. Prices for U.S. Treasuries fell, with the yield on the interest rate sensitive two-year note touching a fresh nine-year high. U.S. stocks were trading mostly higher.
