Gold prices fluctuate amidst market uncertainty.

Gold prices are slightly down due to a rise in U.S. Treasury yields, but losses are limited by a weaker U.S. dollar index. First Republic Bank's quarterly earnings report has caused concern, with the bank's share price dropping nearly 50% on Tuesday. U.S. and global recession fears are also increasing, with diesel fuel prices in the U.S. plunging and United Parcel Service issuing a downbeat corporate earnings report. The metals markets are taking a bearish lean on notions of less consumer and commercial demand if the global economy weakens. Silver prices are near steady.
