GLOBAL MARKETS-Shares, oil slip awaiting US details of Iran sanctions
NVDA•Currency and gold moves
In currency markets, the dollar added 0.2% against its Canadian counterpart to 1.3790 CAD after Prime Minister Mark Carney said his country would respond to U.S. tariffs with levies of its own as trade talks broke down.
Canada will impose tariffs on U.S. steel, dairy, appliances, agricultural equipment, pulp and paper and electronics, along with some products that the U.S. previously targeted in Canada.
The dollar was on the defensive elsewhere after having lost 0.8% last week against a basket of currencies at 96.832. The euro held at $1.1680 after rising 0.9% last week, while the dollar was flat at 158.92 yen.
The dollar has been undermined as investors fret that growing U.S. debt and policy uncertainties will erode the purchasing power of the currency, driving demand for scarcer assets including gold.
The yellow metal firmed another 0.8% to $4,653 an ounce, having climbed 15% for the month so far. If it holds this gain for all of August, it would be the biggest monthly rise on record.
