Gold and silver extended their declines as sharply higher benchmark bond yields in the United States, Germany and Japan reduced the appeal of non-yielding assets. Spot gold fell nearly 1.8% to about $4,370 an ounce, its third consecutive daily decline and a cumulative loss of more than 3.5% across the past three trading sessions. Spot silver dropped nearly 3% to around $64.5 an ounce. The U.S. 10-year Treasury yield rose above 4.75%, while Germany's 10-year yield reached 3.34% and Japan's climbed above 3% for the first time in nearly 30 years. Rising long-term rates increased risk-free returns and pressured precious metals as markets weighed renewed inflation risks and the possibility that major central banks could keep raising interest rates despite escalating conflict between the U.S. and Iran.
