I got a secure email today from my broker advising me that, as of 1 Jan 2018, they would no longer permit me to purchase certain retail bonds due to some new rules about "Packaged Retail and Insurance-based Investment Products (PRIIPs)". Apparently certain types of investments are now off limits unless the issuer has published some kind of information document in a prescribed format (a "key information document" or KID).
Anyways, I did a bit of googling and it turned out these new regulations are from the EU and it isn't completely clear what they cover. The only bonds mentioned in the note were a couple of RPI linkers - I'm wondering if the variable nature of the coupons was what brought them into scope.
Does anyone know anything more about this? Is this part of a wider regulatory attack on the retail bond market or just something that happens to have caught a couple of retail bond issues by accident?
