I still maintain that the high loonie carries the seeds of its own destruction. First it plus the credit squeeze have totally choked off M&A, which was one of the big things that pushed it up. Second, oil is coming off the $84 peak, and in loonies has dropped from $84+ to $79. It had to have been a bad summer for the tourist trade, and with Canadians ordering stuff cheap across the border (L.L. Bean is apparantly swamped with Canadian orders) while Canadian stuff is less attractive down south. Then there's the UAW-Detroit deal which shifts health care legacy costs onto the union and cuts down one of the big advantages the Canadian car industry had, the cheap loonie being another: the Canadian car industry is in trouble now, along with a lot of other manufacturing. The housing slowdown keeps hurting lumber exports, and the high loonie means we get less for resources. All that plus economic slowdown in the US should reduce the trade deficit ... I think the loonie will max out at around .95 and then turn around. Other currencies have been having trouble making headway against USD lately, so the USD weakness may have hit the wall generally. The loonie may stay above parity for another 6 months or so, and then reality will set in. Watch oil.
I am personally doing well out of the horizontal struggle in USDJPY between the carry traders and the weak buck, with occasional forays into EURUSD and GDPUSD when they look weak.
USDCAD I am leaving alone until I see definite signs of a turnaround. Not happy shorting it at a 30-year low.
