TORONTO, Aug 4 (Reuters) - The Canadian dollar dropped to its lowest point against the greenback since July 11 on Thursday, hit by a broad stock market selloff and worries about the U.S. and global economic recovery.

The efforts by Japan and Switzerland to stem their currencies' rise against the U.S. dollar helped the greenback at least briefly, sending commodity-linked currencies like the Canadian and Australian dollars sharply lower.
Global stock markets also dropped, with North American indexes off more than 2 percent at midday, as worried investors took to the sidelines awaiting better economic news.
"You're basically just in a fundamental risk-off frame of mind right now. It's the events in Europe, it's the equity markets catching up to the realization that earnings alone can't get you over this hump, and that you really are in a world where a lot more can go wrong than can go right," said David Tulk, chief Canada macro strategist at TD Securities.
"We're just seeing all the flight to quality right now into the U.S. dollar at the expense of the Canadian dollar."
The Canadian dollar dropped to a session low of C$0.9775 versus the U.S. dollar, or $1.0230, at midday, roughly a three-week low. That was down from Wednesday's North American session close at $0.9626 to the U.S. dollar, or $1.0389.
Tulk pointed to near-term Canadian dollar support at around C$0.98, near levels last seen at the end of June, but warned the run by investors to safe havens may mean previous assumptions about trading ranges may falter.
"At this point, you're starting to get a little more concern, just given that we're seeing this momentum take over. A lot of those technical support levels may have a smaller role to play," Tulk said.
Canadian government bond prices were higher on the broad flight to safety mood.
The two-year bond CA2YT=RR was up 33.5 Canadian cents to yield 1.084 percent, while the 10-year bond CA10YT=RR added 85 Canadian cents to yield 2.571 percent.
