Ivanovich, eto byla shutka. Today, the US, tomorrow the world?
Wasn't it Laurier who said "The twentieth century will belong to Canada"? He may have been off by a century.
No, like all market trends, the rising loonie will self-correct eventually. It's not rooted in US-Canadian trade considerations, because the loonie has been going up against all the other majors as well. And it's not rooted in any weakness in USD, which is doing just fine elsewhere. The high loonie is a consequence of the low loonie, which caused an economic boom and M&A mania, and the low loonie will be a consequence of the high loonie, which will damp down the economy (eventually; don't hold your breath). A US stock market crash and recession (prediction: this fall) should result in a flight of capital from the US and a falling dollar in the short run. In the long run, Canadians rushing to buy cheap American assets with cheap US dollars, plus a collapse of the resource bubble, will drive the dollar up. Maybe even to $1.61, like in the good old days. Maybe in 2009 - 2010 sometime.
The pundits don't think we're headed for parity - the big banks forecast year-end at somehere between 1.04 and 1.08. But I think they are going by the strong economy = strong currency fallacy. It's true for a big exporter like Canada. For the US it's more complicated: strong economy brings in equity investments, so USD beats back EUR, GBP and JPY, but increases the trade deficit, which makes it depreciate against CAD (US FDI accelerates it). Recession reverses all that: up goes USDCAD, and up go GBPUSD and EURGBP.
Logical thing to do when US does slip into recession, the resource bubble breaks and the the equities land, hard or soft, is to reverse my GBCAD short (or maybe long EURCAD - smaller spreads) and get the best of both worlds. I'm calling for GBPCAD to bottom around 2.00 this summer, then get back to maybe 2.20-2.30 by 1Q08. If it works out for me, that's 1000 more pips on the way down and 2-3,000 on the rebound, 3-4,000 pips total. If it works, I'll have a nice summer vacation next year.
