TORONTO, Sept 30 (Reuters) - The Canadian dollar strengthened to a one-week high against the greenback on Wednesday as hopes of additional U.S. stimulus rose and data showed the domestic economy extending its recovery, with the loonie clawing back some of this month's decline.
The loonie CAD= was trading 0.5% higher at 1.3323 to the greenback, or 75.06 U.S. cents. The currency touched its strongest intraday level since last Wednesday at 1.3301.
Still, the loonie posted a monthly decline for the first time since March as rising Canadian coronavirus cases weighed on investor sentiment. It ended September 2.1% lower.
The big driver for investors was news "that there's some progress on the U.S. stimulus bill," said Amo Sahota, director at Klarity FX in San Francisco. "Any motion in that direction is lifting market sentiment up, and that's beneficial for the loonie."
Canada sends about 75% of its exports to the United States, including oil. U.S. crude futures CLc1 settled 2.4% higher at $40.22 a barrel, while shares on Wall Street rose.
