Subordinated debts with a tenor of 5 years or longer issued by a Canadian chartered bank generally qualifies as Tier II capital. Using CIBC as an example, they currently have two outstanding sub-debts that carry a coupon in double digits. An 11.60% sub-debt was issued on January 7, 1991 and a 10.80% sub-debt was issued on May 15, 1991. It appears that CIBC did not issue any sub-debts in 2009 so I don't know if it would carry an interest rate in excess of 11.60%. CIBC and other major Canadian chartered banks are currently paying around 2.10% interest for 5 year GIC's so I would be surprised if any of them would issue a sub-debt for 13%.
On the other hand, a Canadian chartered bank that is lending money could very well be charging a 13% coupon if it is on the basis of a sub-debt issued by the borrower.
Note: This is simply a general discussion of sub-debts and is not applicable to any specific real life scenarios.
