Full-year 2019 real gross domestic products growth is predicted to slow to 2.3 percent, down from 2018's projected 3.1 percent, due to the waning impact of the Budget Reconciliation Act, a widening trade deficit, and moderating business investment growth, according to the Economic and Strategic Research Group at Fannie Mae.

"We expect full-year 2018 economic growth to come in at 3.1 percent, an expansion high, before slowing markedly to 2.3 percent in 2019 and 1.6 percent in 2020," said Fannie Mae Chief Economist Doug Duncan. "Fading fiscal policy, worsening net exports, and moderating business investment all contribute to our projection that GDP growth will begin to slow in 2019."

Consumer spending should continue to be the largest positive contributor to headline growth amid consumer confidence that remains near an expansion best. However, business fixed investment growth, a critical driver of the current expansion, slowed significantly in the third quarter and may be further constrained in the near term by higher tariffs, trade uncertainty, and rising interest rates and input costs.

The most notable downside risks to the forecast include the ongoing trade tensions between the U.S. and China as well as stock market volatility, both of which have the potential to materially impact consumer and business spending. Barring accelerating inflation, Fannie expects both mortgage rates and home sales to stabilize in the new year as the economy slows. Purchase mortgage originations should climb, but a more substantial decline in refinances is expected to result in a small drop in total origination volumes.

“If mortgage rates trend sideways next year, as we anticipate, and home price appreciation continues to moderate, improving affordability should breathe some life into the housing market,” said Duncan. “We also expect residential fixed investment to resume a positive growth trajectory amid continued rising housing starts and stabilizing home sales. However, affordability is likely to remain an industry concern, particularly among first-time homebuyers."

The labor market continues to be one of the economy's high points, and with inflation hovering around the Fed's 2.0-percent target, Duncan anticipates the Fed will hike rates once more in December and two more times in 2019, despite rising market expectations of fewer hikes amid stock market volatility.
