Bond rates have bounced 1/4% in the last month thanks to a sinking dollar and perky economy. That’s prompted Canada’s biggest banks to hike rates. Royal Bank, CIBC, Bank of Montreal, and Scotiabank all boosted their one to five-year mortgages 0.20% on Tuesday. Their 5-year posted rate is now 6.65%. Their “discounted” 5-year rate is about 5.59%.
