Thank you for the question. It is interesting, isn't it?
I think the CIB is an innovative tool, but we are far from the only one. The Nordic countries have partnered together in a very long history around a Nordic bank, and Germany has the KfW with a similar structure.
Since the CIB was launched, the U.K. has announced an infrastructure bank modelled on this one. If you read their legislation, it will be very similar. Of course, most recently, Ontario announced plans to create something similar, so even here....
