Bogus bunch of bankers at Zurich (6)

I believe the answer is:

ersatz

'bogus' is the definition.
(unreal or false)

'bunch of bankers at zurich' is the wordplay.
'bunch of' says the answer is hidden in the clue (a bunch of letters in the clue).
'ERSATZ' is hidden within 'bankers at zurich'.

(Other definitions for ersatz that I've seen before include "Substitute - fake" , "unnatural" , "Made in imitation - in Germany" , "Inferior substitute" , "inferior type" .)

I've seen this clue in The Times.
