Growth in the world’s biggest economy will average 2.3% this year, down from 2.5% seen in a July survey. Gross domestic product expansion is forecast to slow to a 1.8% annualized pace in the third quarter, from 3.1% in the first three months of the year and 2.1% in the second quarter.

“Trade tensions are needlessly roiling financial markets, which could eventually destabilize a stable economy,” Parul Jain, chief investment strategist at Macrofin Analytics LLC in Wayne, New Jersey, said in comments attached to her survey response.
