NEW YORK, March 24 (Reuters) - Global stocks rose for a sixth consecutive session on Thursday, recouping the losses after Japan's natural disasters, while the euro jumped on optimism that European policymakers will be able to control a political and debt crisis in Portugal.
Some investors, however, continued to seek out safety, driving gold to a record high of $1,447.40 an ounce, and silver to a 31-year peak at $38.13. Worries mounted about the ongoing violence in the Middle East and fears that Portugal will, in fact, need a bailout.
Rising borrowing costs for Portugal and a downgrade of 30 Spanish banks' debt by rating agency Moody's had weighed on the euro earlier. Spain's largest lenders were spared the rating cut.
Oil prices wobbled as U.N.-mandated air strikes hit Libya for a fifth night, but failed to stop Muammar Gaddafi's tanks from shelling rebel-held towns. A report a French plane had taken down a Libyan jet raised more worries of a long supply outage.
In Syria, anger mounted as forces fired on protesters, killing at least 37, forcing President Bashar al-Assad to pledge greater freedoms.
The fall of the Portuguese government following the resignation of its prime minister is expected to dominate a summit of EU leaders on Thursday and Friday, with Lisbon under intense pressure to seek a bailout package.[
]"The Portugal story was pretty much priced in," said Samarjit Shankar, managing director of global FX strategy at BNY Mellon in Boston. "Given the rapid events in Portugal and the fall of the government, there might be something that comes out of the summit today and tomorrow."
STOCKS BET ON ECONOMIC RECOVERY
Equity markets gained on bets on a continued economic recovery that were coupled with the end of an upbeat quarter. Light volumes, however, have lately underscored caution.
"What I saw yesterday and today is a stabilization of the market," said Bruce Zaro, chief technical strategist at Delta Global Asset Management in Boston.
"There have been a few good earnings report that have given investors a bit more confidence that earnings are likely to hold...so the story will continue that the rally has been built on strong earnings momentum," he said.
