Using search engines takes you mostly to sites that will tell you how to get an LEI, or the history of their development.
Other than Deutsche Bank, most sites refer to “financial transactions”. The Deutsche web site refers to dealings in “financial instruments”. This could still mean almost anything (but would at least appear to exclude bank accounts, hopefully).
I hope professional bodies are able to offer guidance to their members in good time to enable any necessary registrations to be completed before the year end (I suspect there may be a year-end rush as affected practitioners put it off until they have the time to understand and deal with it!).
As the “issuer” of LEIs for the UK, one could hope The London Stock Exchange will issue a “Dummies” guide to LEIs to assist those who might be affected to understand who needs one, and why (and not just the cost).
