April 16 (Reuters) - Gold prices were steady on Friday as robust U.S. economic data nullified support from lower Treasury yields, although the metal looked set to post a second straight weekly gain on inflationary concerns. FUNDAMENTALS * Spot gold was steady at $1,763.46 per ounce by 0113 GMT. U.S. gold futures were down 0.2% to $1,763.80 per ounce. * Gold was set for its best week in five as inflationary concerns over massive fiscal aids and ultra-low interest rates across the globe kept the metal supported. * U.S. Treasury yields plummeted to one-month lows on Thursday after the U.S. government imposed a broad array of sanctions on Russia as punishment for alleged misdeeds, including interfering in the 2020 U.S. election. * Low bond returns reduce the opportunity cost of holding non-yielding bullion. * Weighing on gold, data showed a better-than-expected rebound in U.S. retail sales in March, while weekly initial claims for state unemployment benefits dropped to the lowest level since mid-March 2020. * China"s economic recovery from a coronavirus-induced downturn earlier last year likely accelerated rapidly in the first quarter, driven by improved demand at home and abroad and continued government support for smaller companies. * Holdings of the largest gold-backed exchange-traded-fund (ETF), New York"s SPDR Gold Trust , fell 0.3% on Wednesday from Tuesday. * Silver was flat at $25.85 per ounce, but up for a second straight week. * Palladium was steady at $2,741.84 but up about 4% for the week. Platinum gained 0.5% to $1,198.21.
