METHODOLOGY FOR CALCULATION OF INTEREST RATES AS THE
BASIS FOR DETERMINING INTEREST RATE CAPS IN ACCORDANCE
WITH THE LAW ON THE PROTECTION OF FINANCIAL SERVICE
CONSUMERS
- For the purpose of applying the Law on the Protection of Financial
Service Consumers (RS Official Gazette, No 19/2025) (hereinafter: the
Law), the National Bank of Serbia regulates in more detail the method for
calculation of interest rates that serve as the basis for determining interest
rate caps in accordance with the Law.
- The basis for calculating the nominal interest rate caps, in
accordance with the application of the Law, shall be the data on the
weighted average nominal interest rates on existing contracts (outstanding
business) and new contracts (new business) that banks submit to the
National Bank of Serbia in accordance with the Guidelines on the
Submission of Data on Interest Rates on Bank Loans and Deposits to the
National Bank of Serbia (RS Official Gazette, Nos 42/2010, 2/2012 and
86/2019) on a monthly basis.
Within the meaning of paragraph 1 of this Section, outstanding
business shall include the accounting balances of bank loans in gross
amounts (without value adjustments) on the last calendar day of the
reporting month. Interest rates on outstanding business shall be calculated
as weighted averages of the interest rates applied to the accounting
balances of loans on the last calendar day of the reporting month.
Loans classified as non-performing, as well as debt restructuring loans
at interest rates significantly lower than market rates shall not be included in
the calculation of interest rates on outstanding business.
Within the meaning of paragraph 1 of this Section, new business shall
include all new loan contracts concluded between a bank and a client
during the reporting period. New business shall include all financial
arrangements for which the terms were agreed for the first time during the
reporting period, as well as all existing contracts for which new terms were
renegotiated with the active participation of the client.
Interest rates on new business represent the weighted average interest
rates on all loan transactions concluded during the reporting month,
excluding debt restructuring loans at interest rates significantly lower than
market rates.
The date of contract conclusion shall be considered the primary factor
for the classification and inclusion of a new loan transaction in the bank’s
report on interest rates for the reporting period.
3. For the purpose of determining the cap on the variable nominal
interest rate applicable to loan contracts with natural persons, the weighted
average interest rate for existing loan contracts of the same type, purpose,
and currency (indexation), which cannot exceed this interest rate increased
by ¼, shall be used. In case of variable-rate housing loans, the cap cannot
exceed the weighted average interest rate for existing variable-rate housing
loan contracts in the same currency (indexation) increased by 1/4. In case
of fixed-rate housing loans, the cap cannot exceed the weighted average
interest rate for new fixed-rate housing loan contracts in the same currency
(indexation) increased by 1/4.1
4. For the purpose of determining the interest rate at the time of
contract conclusion, the effective interest rate caps cannot exceed the
default interest rate under the Law, increased by 4 pp for loan contracts,
and/or reduced by 2.5 pp for housing loan contracts. The effective interest
rate cap at the time of contract conclusion cannot exceed the statutory
default interest rate increased by 6 pp for credit card contracts, and/or 8 pp
for overdraft and overrunning agreements.
5. Given that the Law envisages interest rate caps only for loans to
natural persons, the calculation of the weighted average nominal interest
rate for existing and new business to which the Law applies takes into
account only nominal interest rates on loans approved to natural persons
2
,
where only loan tranches approved at positive nominal interest rates are
included in the calculation.
1 Exceptionally, until 31 December 2025, the variable interest rate for housing loan contracts cannot
exceed 5%, and from 1 January 2026 to 31 December 2027, the variable interest rate for housing loan
contracts cannot exceed the weighted average interest rate for existing variable-rate housing loan
contracts in the same currency (indexation) increased by 1/5. Until 31 December 2025, the fixed interest
rate for housing loan contracts cannot exceed 5%, and from 1 January 2026 to 31 December 2027, the
fixed interest rate for housing loan contracts cannot exceed the weighted average interest rate for new
fixed-rate housing loan contracts in the same currency (indexation) increased by 1/5.
2 The interest rate statistics regularly published on the National Bank of Serbia’s website encompass a
broader household sector, which, in addition to natural persons, includes private entrepreneurs, the
agricultural population, and non-profit institutions.
- The National Bank of Serbia shall publish on its website data on the
level of weighted average nominal interest rates for loan contracts (in RSD
and foreign currency) and housing loan contracts (in RSD and foreign
currency) twice a year, on 1 December of the current year (based on data
as at 30 September of the same year for outstanding business, and/or
based on data for the period from 1 April to 30 September for new
business) and on 1 June of the current year (based on data as at 31 March
of the same year for outstanding business, and/or for the period from 1
October to 31 March for new business)
3
. The National Bank of Serbia shall
also publish data on the level of effective interest rate caps for loan
contracts (in RSD and EUR), housing loan contracts (in RSD and EUR),
credit card agreements (in RSD and EUR), and overdraft and overrunning
agreements, following changes in the key rates of the National Bank of
Serbia and the European Central Bank.
- Banks shall apply the nominal interest rate caps when concluding
loan contracts within 15 days from the date the National Bank of Serbia
publishes the weighted average interest rates in accordance with the Law
and this Methodology.
When concluding loan contracts to which this Methodology applies,
banks must apply the newly calculated effective interest rate within 15 days
from the date of publication of the key policy rate of the National Bank of
Serbia or the rate on the main refinancing operations of the European
Central Bank.
The effective interest rate for the purpose of applying the Law shall be
calculated in accordance with the Decision on Terms and Method of
Calculating the Effective Interest Rate and on the Layout and Content of
Forms Handed out to Consumers (RS Official Gazette, Nos 65/2011 and
62/2018).
The National Bank of Serbia shall publish interest rates in accordance
with this Methodology in the following form:
3 For the purpose of determining the weighted average interest rates on new business in accordance with
the Law, the weighted average interest rates on loan contracts concluded between 1 April and 30
September, or between 1 October and 31 March, shall apply.

** The calculation of the weighted average interest rate, in accordance with the Law, was performed based on the latest available data.
- Housing loans are loans concluded by a bank with a consumer for the purchase, construction, adaptation or reconstruction of residential property
(house, apartment, part of a residential building intended for living, garage, parking space together with an apartment, and land with a building
permit for house construction), secured by a mortgage on residential property, as well as loans concluded by a bank for refinancing such loans.
- Other loans include all loans granted to natural persons except housing loans, credit card debt and current account overdrafts. They also include
energy efficiency loans not secured by a mortgage.
- Until 31 December 2025, the variable interest rate cannot be applied to housing loan contracts, nor can a fixed interest rate be agreed at a value
higher than 5%.
- For credit card contracts concluded before the Law began to apply, the nominal interest rate cannot exceed the default interest rate under Article 11
of the Law, applicable on that day, increased by 6 pp.
- For overdraft and overrunning agreements concluded before the Law began to apply, the nominal interest rate cannot exceed the default interest
rate under Article 11 of the Law, applicable on that day, increased by 8 pp.
