Gold prices surge amid Fed's dovish stance and economic uncertainty.

Gold and silver prices rose after the Federal Reserve raised its main interest rate by a quarter-point but suggested rates will not continue to rise. The Fed Chair leaned more dovish than he had been in recent months, boosting precious metals and briefly rallying US stock indexes. The Swiss National Bank raised its main interest rate by 50 basis points and said the Swiss banking crisis is over. The US stock market was rattled by comments from US Treasury Secretary Yellen that the federal government has no plans to protect all bank deposits that are not FDIC-insured.
