Silver exchange traded funds were down 3% Friday morning as metals ETFs slipped along with global stocks as investors moved into the safety of the U.S. dollar and Treasury bonds.

The iShares Silver Trust (NYSEArca: SLV) slid more than 3% at last check while SPDR Gold Shares (NYSeArca: GLD) dropped 1%.
