CANADA FX DEBT-C$ drops a penny to six week low

* C$ drops to C$0.9861 to the U.S. dollar, or $1.0141

* Bond prices jump as investors continue to exit risk

TORONTO, Aug 8 (Reuters) - Canada’s dollar slid almost a penny to its lowest in almost six weeks against the U.S. currency on Monday, hurt by tumbling oil prices on global unease about a possible double-dip recession and twin debt crises.

The Canadian dollar CAD=D4 fell as low as C$0.9880 to the U.S. dollar, or $1.0127, its lowest since June 28.

Investors were seemingly unimpressed by weekend talks between the Group of Seven industrialised countries aimed at safeguarding the smooth functioning of financial markets following the U.S. debt rating cut to AA-plus from AAA.

“Certainly the backdrop has changed over the last little while,” David Watt, senior currency strategist at RBC Capital Markets.

“I actually don’t think that the S&P downgrade has that much of a direct impact, but it comes at a time when risk sentiment was decidely on edge.”

At 8 a.m. (1200 GMT), it was at C$0.9861 to the U.S. dollar, or $1.0141, down from C$0.9781 to the U.S. dollar, or $1.0224, at Friday’s North American session close.

Uncertainty over economic growth in the United States is a major factor putting pressure on the Canadian dollar, the U.S. being Canada’s biggest trading partner.

“Canada still has a number of safe-haven elements to it, but so long as you’ve got intense uncertainty about the U.S. and global growth outlooks, they’re not necessarily going to shine through,” said Watt.

Government bonds pushed sharply higher, shaking off the S&P downgrade as stocks bore the brunt of the flight from risk.
