Global markets faced a massive sell-off: asset values fell by almost $3 trillion in one day, stock indices in the US and Asian countries accounted for about $1.7 trillion, gold and silver - $1.07 trillion, and crypto-currencies - another $140 billion. At the same time, the yield on US government bonds is rising. Possible reasons include fear of the US election, risk of conflict with Iran and a reassessment of the artificial intelligence sector. The price of gold fell below $3,900 per ounce for the first time since October 3, 2025.
