Erste Bank Hungary, MBH Bank, Takarékbank and Takarék Mortgage Bank were fined for the violations because of the scale of their client numbers and "significant problems" in a review of practices related to early repayment of retail credit.

MNB scrutinized 16 lenders in the targeted probe and found just two of them were in full compliance with rules such as one requiring banks to respond to requests regarding early repayment within five work days.
