Gold slipped on Tuesday as firmer U.S. Treasury yields took some sheen off the yellow metal, with optimism about a quick economic rebound weighing on prices further.


* Spot gold fell 0.3% to $1,728.15 per ounce at 0122 GMT. U.S. gold futures were down 0.2% at $1,729.10 per ounce.

* Treasury yields in the United States have stayed marginally higher after a successful three-year note auction and ahead of important data releases this week, including consumer price inflation on Tuesday.

* Treasury sales of $271 billion in new debt and a key inflation report this week could put an end to the bond market’s recent lull, reinvigorating a surge in yields.
