May 21 (Reuters) - Gold edged lower on Friday, as optimism around a swift economic recovery lifted appeal for riskier assets, although a weaker dollar and growing inflationary pressure limited losses and kept bullion on track for a third straight weekly rise. FUNDAMENTALS * Spot gold was down 0.2% at $1,872.21 per ounce by 0126 GMT, but it has risen 1.6% this week. * U.S. gold futures fell 0.4% to $1,873.70 per ounce. * The dollar was pinned near milestone lows against its rivals and was headed for a weekly loss. A weaker greenback makes gold more appealing for other currency holders. * Benchmark 10-year Treasury yields fell to 1.6340% overnight. Lower bond yields reduce the opportunity cost of holding non-interest bearing gold. * Risk sentiment in wider financial markets remained upbeat after strong U.S. jobs data lifted hopes around a quick economic recovery. * Data on Thursday showed the number of Americans filing new claims for unemployment benefits dropped further below 500,000 last week. * Japan"s core consumer prices slid for the ninth straight month in April, as a record slump in cellphone fees offset rising energy prices. * Britain"s economy will grow much faster than expected this year as a fast-moving coronavirus vaccine programme allows businesses to re-open and lifts confidence, a Reuters poll found. * SPDR Gold Trust , the world"s largest gold-backed exchange-traded fund, said its holdings rose 0.6% to 1,037.09 tonnes on Thursday from 1,031.27 tonnes on Wednesday. * Palladium gained 0.5% to $2,865.73 per ounce, silver eased 0.1% to $27.72, while platinum edged 0.4% higher to $1,200.57.
