Opening bank's initial scope (6)

Ross

I believe the answer is:

breach

'opening' is the definition.
(breach is a kind of opening)

'bank's initial scope' is the wordplay.
'initial' indicates taking the first letters.
'scope' becomes 'reach' ('reach' can be a synonym of 'scope').
The initial letter of 'banks' is 'b'.
'b'+'reach'='BREACH'

(Other definitions for breach that I've seen before include "transgression" , "Gap (in a wall/barrier)" , "Open up" , "part of firearm, say" , "'A custom more 1 down in the ____ ..." .)

I've seen this clue in The Telegraph.
