U.S. stock-index futures turned lower Tuesday after strong gains as the Russian ruble tumbled as the Bank of Russia said it would take further action to stabilize the country's markets after an unexpected interest-rates hike and oil furthered its fall to multi-year lows.
New-home construction in the U.S. topped a million on an annualized rate in November, while housing starts fell 1.6 percent and building permits declined 5.2 percent last month.
The ruble plunged after its worst session in 15 years on Monday. The Russian stock market followed suit, falling sharply.
Falling to lows not seen since the spring of 2009, crude futures for January delivery on Tuesday fell to a low of $53.72 a barrel, and were lately off $2.18, or 3.9 percent, to $53.73 a barrel.
