Five of seven component indexes that make up the leading index rose in the month, pointing to "strengths among the leading indicators (that were) very widespread," the Conference Board said.
The leading index for March rose 0.3 percent to 103.9.
The index uses 2004 as a base year, assigning it a value of 100 for comparison reasons.
Meanwhile Germany's Coincident Economic Index, which measures current business conditions, "edged up by 0.2 percent," which is an annual rate of gain of about 0.4 percent, the Conference Board said.
Moreover, Germany's economic indicators are displaying a clean break from the previous six months.
Between September 2012 and March 2013, the leading index has risen by 1.3 percent, an annual rate of 2.6 percent, "a large improvement from its decline of 2.9 percent -- about a 5.8 percent annual rate -- during the previous six months," the monthly report said.
