NEW YORK, March 24 (Reuters) - Global stocks rose for a sixth consecutive session on Thursday, rebounding from the losses after Japan's natural disasters, while the euro jumped on optimism that European policymakers will be 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 on worries about the ongoing violence in the Middle East and fears that Portugal will, in fact, need a bailout
A downgrade of most Spanish banks' debt by rating agency Moody's and rising borrowing costs for Portugal had weighed on the euro earlier.
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."
Oil prices edged up 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. [
