Gold and silver futures posted substantial gains on Thursday amid a broad-based rally on Wall Street.
COMEX gold for December 2011 delivery settled higher by $35.50, or 2.1%, at $1,765.10 per ounce. Silver futures, per the COMEX December 2011 contract, climbed $0.55, or 1.6%, to $34.50 per ounce.
The advance in precious metals was boosted by the European Central Bank’s (ECB) unexpected interest rate cut, which helped send commodities and stocks considerably higher.
Gold and silver were also boosted by weakness in the U.S. Dollar Index (DXY), which fell 0.6% to 76.636 against a composite of the world’s most traded fiat currencies.
