EghtesadOnline: The global market rally is facing a familiar nemesis: feeble oil prices. In the latest blow, Saudi Arabia announced Tuesday that it raised output back above 10 million barrels a day in February -- reversing about a third of the cuts made the previous month -- sending crude to the lowest level since late November. That pushed stocks and commodity-linked currencies, such as the ruble and the Norwegian krone, lower, while fueling demand for the relative safety of Treasuries.
