Gold prices rose to an all-time high Friday as a cocktail of factors ranging from a weaker dollar, growing expectations for a U.S. interest-rate cut in September to geopolitical tensions in the Middle East bolstered demand for bullion.

Spot gold was up 1.19% to $2,526.50 per ounce by 10:28 a.m. EST. Gold gained 2.5% so far this week.

The dollar index fell 0.3% and was on track for a fourth week of losses, making gold more appealing for buyers overseas.

"The $2,500 hurdle is likely to fall soon though attention will shortly focus on Fed Chair Powell's speech at Jackson Hole a week from today to provide direction for a more detailed outlook on the upcoming rate cuts."
