Does https://en.wikipedia.org/wiki/Basel_III stand corrected? It claims that Basel III won't be implemented until 2019. I raise this question only out of skepticism of Wikipedia's quality of information.

I don't mean to distract or digress. I just stumbled across this old ET post How much do you have to know?, which is a purely put writing strategy. The long term treasury notes in the strategy is of course subject to interest rate risk as pointed out in this article...
