Markets have rallied this month after European Central Bank president Mario Draghi said that the ECB would do whatever it takes to keep the eurozone monetary union intact.
That has been taken to mean that the ECB could ramp up its purchases of government bonds to lower the high interest yields faced by some governments.
But that commitment was thrown into doubt Monday after Germany’s central bank, the Bundesbank, again stressed its skepticism toward those proposed purchases, despite signs Chancellor Angela Merkel is open to the ECB's plans. The German national central bank said in its monthly report Monday that such purchases would carry "substantial risks."
High borrowing costs on government bonds are threatening to ruin the finances of Spain and Italy. Bond purchases could drive down those costs, though an earlier, limited ECB bond purchase program failed to decisively lower them.
"We’re getting some mixed signals coming out of Europe again," said Allan Small, senior adviser at DWM Securities.
"I think the market is learning to digest this and take it with a grain of salt. Once upon a time if we heard mixed signals coming out of Europe, we would be down triple digits. Everyone is kind of, enough is enough."
In another development, German news magazine der Spiegel reported that the ECB was contemplating setting concrete yield caps above which it would intervene to drive borrowing rates down.
However, the ECB said in a statement that it was "wrong" to speculate on the shape of future ECB interventions. It said its policies remained independent of governments and that it would act "strictly" within its mandate, which stresses preserving price stability as the first priority.
The base metals sector led decliners, down about 0.73 per cent as copper prices gave back last week's three-cent gain, with the September contract in New York off five cents at US$3.37 a pound. First Quantum Minerals (TSX:FM) gave back 42 cents to $19.37 and Taseko Mines (TSX:TKO) was off four cents to $2.61.
Copper fell as hopes dimmed of further stimulus from Chinese policy-makers. A report over the weekend that property prices in July rose slightly discouraged investors who have been hoping for further big stimulus measures from the Chinese government.
China is the world’s biggest consumer of copper, viewed as an economic bellwether as it is used in so many industries.
Energy stocks also gave up ground as oil prices reversed early gains, with the September contract on the New York Mercantile Exchange down four cents to US$95.97 a barrel. Suncor Energy (TSX:SU) fell 23 cents to $32.20.

Lowe's has said it would like to acquire Rona Inc. (TSX:RON), Canada's largest home-improvement retail chain, but its $1.76-billion offer has been rejected by the company and also faces opposition from the province of Quebec.
Apple is the world's most valuable company ever, amid optimism around what is believed to be the impending launch of the iPhone 5, and possibly a smaller, cheaper iPad.

Its stock closed up 2.62 per cent to US$665.15.
