Globally gold nudged higher on Tuesday as investors weighed mixed signals on potential U.S.-Iran ‌talks and awaited a series of U.S. labor market reports this week for clues on the Federal Reserve's interest-rate trajectory, Reuters reported.

Spot gold rose 0.2% to $4,059.81 per ounce, with investors looking ahead to reports on the U.S. labour market, including job opening data later in the day, the ADP employment report on Wednesday and nonfarm payrolls ⁠figures on Friday.
