Silver ETFs are seeing departures ahead of the Federal Reserve’s December meeting, at which the central bank is expected to raise interest rates, a move often seen as negative for precious metals.

“Silver has tumbled about 7 percent since trading at a four-month high in September as precious metals lose favor amid the record-breaking rally in U.S. equity indexes,” according to Bloomberg. “Solid earnings reports from companies including Caterpillar Inc. are fueling optimism about global growth, bolstering the case for the Federal Reserve to keep raising borrowing costs and hurting the investment appeal of non-interest-bearing assets including gold and silver.”

Investors can tap silver equities with the Global X Silvers Miners ETF (NYSEArca: SIL) and related ETFs. SIL, the largest silver miner-related ETF, tries to mirror the Solactive Global Silver Miners Total Return Index, which is also comprised of global silver miners.
