Silver futures soared 14%, the metal's biggest one-day jump in over 40 years, to a fresh record above $115 a troy ounce. Gold futures rose 2.1% to surpass $5,000 a troy ounce for the first time, boosted by tariff threats against Canada and the possibility of a fresh U.S. government shutdown. The upswing in precious metals boosted mining companies such as Freeport-McMoRan and Newmont.
