  "Summary": "Gold held steady near $4,400 an ounce on Thursday, retaining gains from the previous session as investors cautiously awaited key US inflation readings that could provide further insight into the Federal Reserve 2019s next policy move. The US producer price index report for August is due later today, followed by the consumer inflation report on Friday. The metal found support from a weaker dollar, as well as continued demand for its long-term hedging appeal despite near-term pressure from higher oil prices and bond yields. Oil prices climbed to multi-month highs as the US-Iran conflict intensified, stoking inflation concerns and strengthening expectations for near-term rate hikes. US Treasury yields also moved higher after the Treasury Department announced plans to buy back up to $6 billion in longer-term debt, disappointing some investors who had expected a more substantial increase.",
