The association said that most of the debtors had not signed valid conversion agreements or annexes to the existing loan agreements, but only declarations on acceptance of the conversion.
If the authorities do not prolong the capping of the CHF-HRK exchange rate at 6.39 kuna for those loan-holders after 25 January, they would start paying higher instalments, the association said in a press release.
On the other hand, most lenders said in their answers to HINA's inquiry that the procedures for the conversion of the CHF-indexed loans were under way and that they could not give the precise number of those who opted for the conversion.
For instance, Hypo Alpe-Adria-Bank stated that 92% of its customer with CHF loans had agreed to the conversion, adding that it believed that the requests for the conversion would be realised in the first quarter of 2016.
Raiffeisenbank Austria (RBA) said that the response of its clients was positive.
Privredna Banka Zagreb said that some 95% of customers eligible for loan conversion had accepted this option and nearly 80% of them had completed the conversion to date.
Splitska Banka and OTP also reported that nearly all CHF-pegged loan holders had opted for the conversion.
