LONDON, July 14 (Reuters) - Gold prices extended earlier gains to record highs for a second day on Thursday after hints of further policy easing from the Federal Reserve and a Moody's warning the United States may lose its top-notch credit rating hurt the dollar and sparked buying of safe-haven assets.
Concerns over the scope of the euro zone debt crisis are also sparking fresh inflows into gold.
Spot gold hit a high of $1,592.70 an ounce and was up 0.65 percent at $1,592.24 an ounce at 0920 GMT. The metal hit record highs in South African rand, at 10,914.90 rand and ounce, and Canadian dollars, at C$1,526.12 an ounce. (Reporting by Jan Harvey; Editing by Alison Birrane)
