A slowing global economy and rising fears over trade wars have produced steep changes in the value of scrap metals in obsolete electronics. Some prices have risen dramatically while others have fallen sharply. On the upside, investors are moving away from equities as share prices are weakening. Precious metals such as gold and silver are thus seen as safe havens for investors with cash. As of early August, the value of gold had risen 15% since spring and was at a six-year high of about $1,500 per troy ounce. Similarly, silver was at its highest price in the past year, at approximately $17 per ounce. However, values of other metals found in e-scrap are driven more by industrial demand than investor speculation, and global economic concerns have helped push scrap metal prices lower.
