World stock markets cautiously rebounded Wednesday in a week that saw Europe's debt crisis return to center stage over concerns Greece would not attract enough investor support for a deal meant to head off a messy default.
Investors have also been concerned about global growth, especially in light of the recent rise in oil prices. But Wednesday's modest rally seemed to indicate some are holding out hope that data from the U.S. later in the day will show the world's largest economy continues to generate new jobs.
Analysts warned, however, that the rally in shares could be short-lived since worries over Greece remain _ and not just in the short term.
"It is perfectly possible that the eurozone and Greece could find themselves in three years time in exactly the same spot they were in at the start of this year," said Simon Derrick, an analyst with Bank of New York Mellon. "Whether the political will for such a top-up would be there by 2015 of course remains very much open to question. Little wonder then that the issue of a eurozone exit should remain very much on the agenda."
More imminently, Thursday marks the last day the country's private creditors can sign up to a deal meant to slash euro106 billion ($139 billion) off Athens' books and hopefully put it on the path to recovery.
The creditors will take hefty losses if they agree to swap their bonds, but European leaders have painted the deal as the only way to prevent a messy Greek default that would have widespread repercussions for banks and economies throughout the 17-country eurozone.
Private creditors have been asked to accept to swap their bonds for new ones with a face value that is 53 percent lower and with longer maturities and lower interest rates. Some creditors, including hedge funds, are thought to be weighing up the benefits of holding out for a potentially bigger insurance return.
If the takeup is below 90 percent, but still above the crucial 66 percent threshold for the deal to go ahead, the Greek government could force holdouts to accept the swap. That may be considered a credit event _ a technical term for a default _ meaning bond insurers would have to pay the Greek bondholders.
Worries over the swap sent stocks tumbling this week, including a more than 200-point drop in the Dow Jones industrial average on Tuesday, that ended a streak of calm.
But, on Wednesday, stocks rose ahead of a private payrolls report from the U.S. that analysts expect to show solid growth.
In Europe, the French CAC-40 was up 0.8 percent at 3,390, while Germany's DAX rose 0.5 percent to 6,664. The FTSE index of leading British shares edged up 0.3 percent 5,781.
The euro also nudged up to $1.3154.
Wall Street was set to open a bit higher. Dow futures gained 0.4 percent at 12,798, while S&P futures rose 0.5 percent to 1,348.
Investors are also worried about oil prices, which are charging up amid unrest in Syria and Libya and tensions between Israel and Iran. Disappointing growth figures from Australia and Brazil and a report showing that the combined economies of euro countries shrank at the end of 2011 have called into question the strength of a nascent global recovery; inflated energy prices could further weigh on any rebound.
