I noticed a trend that starting in 2010, the number of $5 bills in circulation started to decline after hitting its peak in 2009. Funny thing is, in my region, the number of new $5 prefixes went down starting in 2008. The number of new $10 prefixes, in 2012 so far in my region, have been very few, and very far between. Only a very small range of BFU and eventually BFT were seen in my region in 2012, though I think the BFT's I got were probably shipped to Sobeys and not to the Scotiabank I presently deal with. But oddly enough, I noticed the number of $10 bills across Canada have gone up starting in 2004, until at least 2010. I was so used to seeing about 5 new prefixes for the $10 bill a decade ago. Now I probably only see 2 new prefixes annually (though by 2014, it won't be the case for at least a few years). There seems to be a trend going on.
My question is, is there any word on how many $10 bills and $5 bills were in circulation in 2011?
And are banks likely ordering the new $10 bills less and less in preparation for the soon-to-be released Polymer $10's? After all, the cost to order the Polymer $10 bills may be more than the paper $10 bills, and maybe the banks are retaining the money they would normally spend on ordering new paper $10 bills so that they can add that to the bank's budget to order the possibly more expensive new Polymer $10 bills when they are released, so the bank is probably devoting this entire 2012 and part of 2013 to total recycling of $10 bills.
If demand for the $10 bill in my region is quite low now, I have a feeling most of my region's $10 bills will be replaced by the Polymer versions probably within 3 months.
