I have found some recent news about Stellar XLM.
Apparently, some 30-40 banks will use XLM.
I am still trying to find out if this is real or not but it seems that the news is not that new.
Feb 20, 2019 - 40-50 banks expected to use Stellar-powered IBM World Wire.
Latest Reddit discussion.

Does anyone know for sure if this is true?
