The economy is expected to have ended 2016 with a 2.2 percent annualized growth rate, according to the median estimate of economists in a Bloomberg survey. While that would be fairly typical of the country's Obama-era expansion, it is far below the level promised by President Trump, who is looking to introduce protectionist policies and prune regulations to boost the economy. Fourth-quarter gross domestic product data will be released at 8:30 a.m. ET.
