Spending on information technology is rebounding, but national debt crises in many countries will dampen what could be stronger growth, says a new report from Forrester Research.

Tech sector analyst Andrew Bartels tracks the IT market worldwide for Forrester. In his latest quarterly report, he claims IT spending is growing again, on track to increase 8.4 percent worldwide in 2010.

In the United States, the growth rate will be 7.7 percent, he says, but that’s because the U.S. dollar has gotten stronger after the Greek debt crisis damaged the euro.

Bartels had predicted a recovery in a January report, but he now says that spending on communications equipment is more than he expected.

Largest IT markets in America for 2010:

  • Professional services — $103 billion
  • Financial services — $81 billion
  • Government — $71 billion

Meanwhile, Western and Central Europe will suffer, says the report, because of those countries’ national debt worries combined with the weakened euro.
