Gold weakened amid renewed expectations for higher U.S. interest rates later this year. Federal Reserve Governor Jerome Powell said Tuesday there was a 50-50 chance of a rate hike at the Fed's September meeting and added that he envisioned a second hike in December.
Meanwhile, U.S. data showed that new home sales jumped to a more than seven-year high in May, bolstering the outlook for the economy.
A separate report showing a rebound in business investment plans last month also boosted the outlook for growth this quarter after a weak start to the year.
The upbeat data boosted optimism over the health of the economy and supported the case for a U.S. interest rate hike later this year.
Expectations of higher borrowing rates going forward is considered bearish for gold, as the precious metal struggles to compete with yield-bearing assets when rates are on the rise.
