According to some, bank transferred parts (10)

I believe the answer is:

reportedly

'according to some' is the definition.
(according to some reports)

'bank transferred parts' is the wordplay.
'bank' becomes 'rely' (to bank on is to rely on).
'transferred' becomes 'ported' (port can mean to carry or transfer).
'parts' is an insertion indicator (in the sense of cuts or separates).
'rely' placed around 'ported' is 'REPORTEDLY'.

(Another definition for reportedly that I've seen is " we hear".)

I've seen this clue in The Guardian.
