In the international market, US gold futures for December delivery rose about 1 per cent to $4,380 per ounce.

The buying in gold supported by a decline in crude oil prices which eased pressure on the US dollar and Treasury yields.

In addition, the Federal Reserve is widely expected to raise interest rates by 25 basis points, as per experts.

Moreover, geopolitical tensions also remained a key factor for bullion prices as the US-Iran conflict remains unresolved while reports of a Houthi drone being intercepted by Saudi Arabia and explosions on Iran's Qeshm Island added to market uncertainty.
