Ban accordingly restricting business degree (7)
I believe the answer is:
embargo
'ban' is the definition.
(thesaurus)
'accordingly restricting business degree' is the wordplay.
'accordingly' becomes 'ergo' ('ergo' can be a synonym of 'accordingly').
'restricting business' is an insertion indicator (I've seen this in other clues).
'degree' becomes 'mba' (MBA is an example).
'ergo' going around 'mba' is 'EMBARGO'.
(Other definitions for embargo that I've seen before include "Government order imposing a trade barrier" , "Block" , "Prevent publication" , "Trading restriction" , "Commercial ban" .)
