German gross domestic product grew 0.3 percent sequentially, slower than the 0.6 percent expansion seen in the previous quarter, data from Destatis showed Tuesday. GDP was expected to climb at a slightly faster pace of 0.4 percent. Nonetheless, Destatis said this was the 15th quarter-on-quarter growth in a row, contributing to the longest upswing phase since 1991. On a yearly basis, calendar-adjusted GDP climbed 2.3 percent after expanding 2.9 percent in the fourth quarter. Similarly, price-adjusted growth eased to 1.6 percent from 2.3 percent a quarter ago.
