Misleading advert for banking facility (9)

I believe the answer is:

overdraft

I'm a little stuck... Click here to teach me more about this clue!

'banking facility' is the definition.
'overdraft' can be an answer for 'facility' (I've seen this before). I'm not sure about the 'banking' bit.

'misleading advert for' is the wordplay.
'misleading' is an anagram indicator (I've seen this in other clues).
'advert'+'for'='advertfor'
'advertfor' anagrammed gives 'OVERDRAFT'.

Can you help me to learn more?

(Other definitions for overdraft that I've seen before include "For advert, allowed to exceed amount lodged in bank" , "Bank borrowing" , "financial licence" , "Bank account deficit" , "Bank facility to go into the red" .)

I've seen this clue in The Telegraph.
