U.S. stock index futures indicated a flat open on Tuesday ahead of a number of key data releases, amid choppy trade in currencies and oil.
U.S. Consumer Price Index rose 0.2 percent in February, in line with analysts' expectations, the Labor Department said Tuesday morning. This after dropping 0.7 percent the previous month.
The so-called core CPI, which strips out food and energy costs, increased 0.2 percent in February after a similar gain in January. In the 12 months through February, the core CPI rose 1.7 percent, the largest increase since November.
A recovery in energy prices during the month is likely to account for part of the rise—core inflation is expected to have increased only marginally.
Other releases include new home sales for February at 10 a.m., which are likely to be somewhat weaker than in January.
Plus, the FHFA's house price index for January is out at 9.00 a.m., as well as two U.S. manufacturing surveys for March.
