Greek uncertainty continues to weigh on global markets

Global stock markets drifted lower Tuesday as investors fretted over Greece and positioned themselves for a run of U.S. economic data that culminates at the end of the week with the closely watched nonfarm payrolls report for May. In Europe, France's CAC 40 dropped 0.1 percent to 5,020 while Germany's DAX shed 0.7 percent to 11,356. Britain's FTSE 100 fell 0.5 percent to 6,921. U.S. stocks were set for modest losses at the open with Dow futures and the broader S&P 500 futures down 0.1 percent.

A day after an emergency mini-summit of Greece's international creditors, the country submitted a proposal it hopes will help break the logjam and secure a deal that will unlock desperately needed rescue money. Greek Prime Minister Alexis Tspiras said it was now up to the leaders of Europe, who are Greece's main creditors, to accept a deal or risk potentially disastrous consequences for the region. For four months, Greece and its creditors have been locked in a standoff over what reforms the country needs to make to get more loans. Tsipras gave no specifics of what was included in the proposal included, which was submitted Monday night to the European Central Bank, International Monetary Fund and European Commission, the EU's executive. "There are some small signs of progress being made although that is doing little to settle the markets, with most European equity indices in the red," said Craig Erlam, market analyst at OANDA.

Another big focus this week will be the state of the U.S. economy. A slew of data ends Friday with May payroll figures. They can set the market tone for a week or two after their release, especially at a time when investors are trying to work out when the Federal Reserve will start raising interest rates. Recent figures have been mixed. Japan's Nikkei 225 closed down 0.1 percent at 20,543.19 while China's Shanghai Composite rose 1.1 percent to 4,910.53.. Hong Kong's Hang Seng shed 0.5 percent to 27,466.72. Australia's S&P/ASX 200 dropped 1.7 percent to 5,636.00 ahead of a central bank interest rate decision. Seoul's Kospi sank 1.1 percent to 2,078.64. Benchmark U.S. crude was up 82 cents at $61.02 a barrel in electronic trading on the New York Mercantile Exchange. Brent crude, a benchmark for international oils, gained 55 cents to $65.43 a barrel in London.
