Gold prices were little changed on Tuesday as investors awaited the Federal Reserve's annual conference this week for cues into possible rate cuts, and weighed Washington's efforts to end the war in Ukraine.

Later this week, economists, central bankers and members of the business press will gather in Jackson Hole, Wyo. for the Kansas City Fed’s annual Jackson Hole Economic Policy Symposium.

This week's set-piece event is the Jackson Hole central-bank gathering in Wyoming, slated for Thursday through Saturday. Investors will be glued to Federal Reserve Chair Jerome Powell's speech, hoping for any insight into whether the central bank might kick off interest-rate cuts in September.
