Gold prices are heading towards their first monthly fall in three months, reflecting a reduced demand for bullion in light of potentially rising interest rates in the US and confidence in the country's debt deal. Spot gold has not moved from $1,958.02 per ounce with U.S gold futures at $1,957.80 remaining the same but down 1.6% for May. The possibility of the US Federal Reserve raising the interest rates next month has grown as economic data beats expectations.
