We blogged the draft version a few months ago; at that stage it was just Citi and Bank of America Merrill Lynch. Things have moved forward and yesterday a more developed version was published. Now there are 13 banks involved, with JP Morgan and Credit Agricole joining the first two in the driver's seat.
This is a big development; and with even more banks expected to now sign up to the Principles they are likely to have a major impact on development of the market.
