In commodities, gold (XAUUSD) extended its strength, with spot gold rising to near $4,660/oz intraday, setting a new high in over three months. A weaker U.S. dollar, concerns over U.S. fiscal sustainability, and market hedging against Fed policy risks continued to support safe-haven demand.
International oil prices pulled back slightly from high levels, with WTI (USOIL) crude trading near $85 and Brent crude pulling back to near $91. As the U.S. prepares to step up economic sanctions on Iran and Iran warns it could block oil exports through the Strait of Hormuz and the Persian Gulf, the risk premium on oil prices remains high.
