Gold slid over 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 $4,059.11 per ounce by 0356 GMT. U.S. gold futures for August delivery were ⁠down 1.1% at $4,067.10. U.S. and Iranian forces have exchanged heavy missile and drone assaults, with Tehran targeting U.S. 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 U.S. ​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. Kevin Warsh's first semiannual testimony before Congress as Federal Reserve chair, along with a slate of key U.S. economic data, including June CPI, PPI and retail sales, will be closely watched this week for fresh clues on the economy, inflation and the monetary policy outlook.

Remarks from Fed policymakers, including Vice Chair Michelle Bowman and Governor Christopher Waller, later in ‌the day are also in focus as they could provide insights ⁠on how inflationary pressures are affecting the central bank's stance ​on interest rate hikes.

Traders are currently pricing in a 72% chance of a U.S. Fed interest rate hike in September, up from about 63% last week, according to the CME FedWatch ​Tool.

Elsewhere, spot silver ‌declined 2.9% to $58.14 per ounce, platinum shed 1.8% to $1,598.48, and ⁠palladium fell 2.3% to $1,247.27. (Reporting by Pablo Sinha ​and Swati Verma in Bengaluru; Editing by Subhranshu Sahu and Rashmi Aich)
