Gold spiralled by Rs 990 to Rs 31,350 at the bullion market here on Friday on the back of positive global trend as the dollar fell to its weakest level since 2015, and tension between North Korea and the US intensified further.

Trading at a 10-month high of Rs 31,350 per ten gram, the metal witnessed the biggest one-day surge this year. However, demand from local jewellers remained low in view of the ongoing inauspicious fortnight of 'Shradh.' Silver also rose to Rs 42,000 per kg backed by increased offtake by industrial units and coin makers.

Bullion traders said sentiment got a boost after gold rallied to the one-year high in the global market as the dollar fell to its weakest level since 2015 in the backdrop of warnings that Hurricane Irma could have the devastating impact on the US amid weaker-than-expected jobs data.

Besides, simmering tension between North Korea and the US added to the uptrend. Also, a firm trend at the futures market supported the price rise, they added.
