Gold prices increased slightly in Asia, supported by a weaker dollar, but was range-bound as traders watched for the critical U.S. debt ceiling vote. Spot gold rose 0.2% to $1,965.61 per ounce while U.S. gold futures increased 0.2% to $1,965.20. The dollar index eased from a more than two-month high, prompting buyers from overseas to purchase more of the metal. Investors kept a watchful eye on the vote, which would be critical to global financial markets if a default occurred. Data showed that U.S. job openings in April increased, pointing to a strong labour market with the potentiality to prompt the Fed to raise interest rates.
