(Reuters) - Spot gold held steady on Tuesday, after a warning by ratings agency Standard & Poor's that it would treat plans for a rollover of privately-held Greek debt as a selective default, underpinning safe haven demand for bullion.
* Spot gold rose 0.09 percent to $1,496.84 an ounce by 0038 GMT (8:38 p.m. EDT).
* U.S. gold gained 1 percent to $1,497.60.
* Rating agency S&P warned Greece would likely be in default if it follows a debt rollover plan pushed by French banks.
* The euro hovered near one-month highs versus the dollar, shrugging off S&P's warning on Greece, as expectations that the European Central Bank will raise interest rates on Thursday helped buoy the single currency.
* The dollar index .DXY gained slightly on Tuesday, but remained near one-month lows.
* U.S. crude futures edged up on Tuesday to remain above $95 a barrel, ahead of U.S. factory orders data gauging the strength of the world's top economy and oil consumer.
