EBA Authorithy: banking money is FIAT CURRENCY

European Banking Authority
EBA: The banking money is FIAT CURRENCY 
From the EBA EBA Opinion / Op / 2014/08, July 4, 2014, https://www.eba.europa.eu/documents/10180/657547/EBA-Op-2014-08+Opinion+on+Virtual+Currencies.pdf 

Expressing the difference between Virtual Currency (VC) and Fiat Currency (FC) concerning the bitcoin, states, in paragraph 19:

"VCs are defined as a digital representation of value that is neither issued by a central bank or public authority nor necessarily attached to a FC, but is used by natural or legal persons as a means   of exchange and   can   be   transferred,  stored   or   traded   electronically. (7) VCs   can therefore be characterised along the distinguishing features specified below. Although some of the features resemble activities or products that are already within the remit of the EU  E-Money Directive, these products  are not intended to be included here, as  e-money is a digital representation of FC, which VCs are not."

And, in note 7: ""It is theoretically conceivable that a central bank or public authority might back a particular VC scheme. However, it can be reasonably argued that, in this case, the currency is no longer a virtual but a fiat currency."
 
Since commercial banks, which are not public authorities or central banks, adopt a VC scheme (the virtual currency deposits) but this VC is supported (backed: supported, endorsed) by the public authorities and the central bank, therefore it can be said that their VC is an FC, a Fiat currency., A.K.A., "legal tender", or "fiat currency".
