Investors are waiting for the end of the Fed meeting on Wednesday to gauge policy makers' take on the economy and the timing of an interest rate increase. Also, reports on second-quarter US gross domestic product and on the jobs market are due on Wednesday and Friday respectively.
Then there are second-quarter corporate earnings to digest too.
"It's another big week of earnings, with the jobs report on Friday," Michael James, a Los Angeles-based managing director of equity trading at Wedbush Securities, told Bloomberg News. "Sentiment in the short-term term is a little more cautious."
The US economy probably expanded at a 3.0 per cent annual rate in the second quarter, according to a Reuters survey of economists. The world's largest economy shrank 2.9 per cent in the first quarter.
"Pretty much across the board, components will look better," Jim O'Sullivan, chief US economist at High Frequency Economics in Valhalla, New York, told Reuters. " I do think we can sustain a 3 per cent growth number for the next couple of quarters."
But some are worried the pace of recovery will fall short of expectations.
"We should expect a rebound in the second quarter, but we don't think the rebound is going to be as strong as the market expects," Vassili Serebriakov, a New York-based foreign-exchange strategist at BNP Paribas, told Bloomberg News.
In Europe, the Stoxx 600 Index finished the session with a 0.2 per cent decline. The UK's FTSE 100 Index inched 0.05 per cent lower, while Germany's DAX fell 0.5 per cent. France's CAC 40 rose 0.3 per cent.
