The increase of interest rates on mortgages would impact only 20 per cent of the banks' clients that had already taken mortgages according to data of Bulgarian credit company CreditCentre.

Two banks in Bulgaria have so far increased their interest rates on mortgages and four banks have changed the conditions on part of the credits that had been already taken, investor.bg reported.

Banks in Bulgaria have offered more than 80 promotional products in the past one-year period and that is why the change in interest rates would influence them in a different way, CreditCentre said.

Changes in interest rates on mortgages by banks could be divided into three categories. The first one includes banks that changed their interests for old and new clients, the second group includes the banks that changed their conditions for old clients only and the third group includes the bank that have not changed their interest rates yet.

For the period from August 10 when the first public interest rate increase was made until September 10 the number of enquiries for mortgage loans decreased by 4.6 per cent.

According to CreditCentre's estimations those bank clients who would be affected by the interest rate's increase would have to pay a small sum above their current monthly instalments. Clients that have taken a credit for 30 000 euro (58 600 leva) for a period of 20 years with an average monthly instalment of 450 leva would have to pay 3.3 per cent more.
