Office market fundamentals have continued to improve across all three global regions, with buoyant leasing activity and tightening supply supporting solid rental growth. Global leasing volumes in the final quarter of 2015 were 14% higher year-on-year and, as a result, full-year volumes exceeded expectations, registering 8% growth on 2014 levels. The Asia Pacific region has seen a strong rebound, with its full-year volumes 19% higher. Leasing activity has also been remarkably vigorous in Europe, posting 13% growth in 2015. Meanwhile, the U.S. has maintained its robust leasing activity, with nearly half of volumes comprising expansion demand. Technology, banking and financial services and outsourcing are the key drivers of demand.
