NEW YORK/LONDON, March 16 (Reuters) - Gold rebounded Wednesday after the previous day's 2 percent drop, as investors shifted the focus back on loose monetary policies and geopolitical tensions and away from Japan's nuclear crisis.
Bullion was underpinned by a European Central Bank policymaker's comment which suggested the ECB could possibly delay an April interest hike, and after Moody's credit rating agency downgraded Portugal by two notches late Tuesday.
"Now that the dust has settled a little bit and we've had particularly a recovery in energy and other commodities, that's given a tailwind to gold," said HSBC analyst James Steel. "If the focus ceases to be entirely on Japan, and the Middle East again gets some headlines, then the geopolitical risk levels will come back in and support gold."
ECB's comment gave gold a slight boost and economists said it had not significantly diluted expectations of a rate hike in April.
European and U.S. shares slid for a third day, and that stoked safe-haven buying in gold and also U.S. Treasuries, as the nuclear crisis in Japan raised concerns about slower worldwide growth. [

Unrest that swept the Middle East and North Africa earlier this year, a key factor pushing gold to a record $1,444.40 an ounce last week, continues to simmer.
The Libyan army closed in on the opposition bastion of Benghazi on Wednesday, while in Bahrain forces fired tear gas in a crackdown on protesters. [
