Gold prices slid more than 1% on Monday as fears of a closure of the Strait of Hormuz drove oil prices sharply higher, reviving expectations of elevated interest rates to combat inflationary pressures from escalating hostilities in the Middle East.
Spot gold dropped 1.5% to $4,060.49 per ounce by 0735 GMT. US gold futures for August delivery were down 1% at $4,069.50, Reuters reported.
US and Iranian forces have exchanged heavy missile and drone assaults, with Tehran targeting US facilities in states across the Gulf on Sunday and saying it had again closed the vital Strait of Hormuz.
Oil prices jumped about 4%, the dollar and US Treasury yields climbed, and share markets slipped in Asia.
"Any breakout of violence in the Gulf is accompanied by pressure on gold," said Nicholas Frappell, global head of institutional markets at ABC Refinery.
"The question is, if the Strait of Hormuz remains effectively or partially closed, does that lead to a deflationary effect, further down the road, that might actually be supportive for gold if you have demand destruction leading to lower economic activity," Frappell added.
