"Although global IT spending is forecast to grow 6.2 percent this year, the declining U.S. dollar has caused currency tailwinds, which are the main reason for this strong growth," said John-David Lovelock, research vice president at Gartner. "This is the highest annual growth rate that Gartner has forecast since 2007 and would be a sign of a new cycle of IT growth. However, spending on IT around the world is growing at expected levels and is in line with expected global economic growth. Through 2018 and 2019, the U.S. dollar is expected to trend stronger while enduring tremendous volatility due to the uncertain political environment, the North American Free Trade Agreement renegotiation and the potential for trade wars."

Enterprise software spending is forecast to experience the highest growth in 2018 with an 11.1 percent increase. Barring unexpected disruption, the software industry is expected to continue capitalizing on the evolution of digital business. Application software spending is expected to continue to rise through 2019, and infrastructure software will also continue to grow, bolstered by modernization initiatives.

Even with a strong end to 2017, worldwide spending on data center systems is forecast to grow 3.7 percent in 2018, down from 6.3 percent growth in 2017. The longer-term outlook continues to have challenges, particularly for the storage segment. The strength at the end of 2017 was primarily driven by the component shortage for memory components, and prices have increased at a greater rate than previously expected. Whereas previously, component shortages were expected to ease into 2018, the shortages are now expected to continue throughout the year with the supply not expected to ease until the end of the year.

Worldwide spending for devices — PCs, tablets and mobile phones — is forecast to grow in 2018, reaching $706 billion, an increase of 6.6 percent from 2017. "The device market continues to see dual dynamics. Some users are holding back from buying, and those that are buying are doing so, on average, at higher price points," said Mr. Lovelock. "As a result, end-user spending will increase faster than units through 2022. However, total end-user spending and unit shipments are expected to be lower compared with previous forecasts, as demand for ultramobile premium devices, ultramobile utility devices and basic phones is expected to be slow."
