IRCC, the consumer credit reference index (Indicele de Referință pentru Creditele Consumatorilor), is the benchmark against which interest on Romania's variable-rate loans adjusts. It appeared in 2019, through OUG 19, after public frustration with ROBOR, which reacted daily to the interbank market and could push a mortgage installment up by hundreds of lei in one week. The legislator's idea: installments should track the real cost of the money banks attract, not one-day speculation.
IRCC has since been the standard index for new variable-rate loans, consumer and mortgage alike. Loans signed before 2019 may still run on ROBOR; contracts concluded after 2 May 2019 get it automatically.
Key points
• IRCC is calculated quarterly by the BNR from deposit interest rates
• The loan's interest rate = IRCC + the bank's fixed margin
• The monthly installment is recalculated every quarter
• The bank must give at least 30 days' notice
• On variable IRCC loans, early repayment is free
How IRCC is calculated
The BNR computes IRCC as the weighted average of rates on deposits maturing within one year, attracted by commercial banks in the previous quarter. The exact formula comes from BNR Regulation 9/2019, published transparently. The official value appears on bnr.ro at the start of each quarter, once aggregated data is validated.
The loan's rate equals the current IRCC plus the fixed margin negotiated at signing. The margin stays unchanged for the loan's entire life, whatever IRCC does. Only the index moves.
A worked example on a real case
With IRCC at 5.42% and a bank margin of 3.5%, the nominal rate paid is 8.92%. On a 73,500 lei loan over 60 months, the installment comes to 1,523 lei. If IRCC climbs to 5.67% the next quarter (as it actually did in May 2026), the new rate is 9.17% and the installment rises to 1,534 lei. A difference of 11 lei per month, barely felt.
But four quarterly rises of 0.3% each take IRCC to 6.62%, the rate to 10.12%, the installment to 1,583 lei. Cumulative gap: 60 lei monthly, 3,600 lei over the term. That registers.
How it differs from ROBOR
ROBOR (Romanian Interbank Offer Rate) measured daily interbank rates, the price at which banks lent each other money short term. It moved fast, sometimes jumping 0.3-0.5% in a month. For someone on 3-month ROBOR, installments danced unpredictably. In 2018-2019 some families saw their installment climb 280-340 lei in one quarter, purely from market swings.
IRCC adjusts only quarterly, with a lag. One-day shocks get diluted in a 90-day average. For the consumer, predictability is visibly better. BNR data, p. 31 of the 2024 annual Financial Stability Report, shows IRCC volatility was 3.4 times lower than ROBOR's over 2020-2024.
Comparison table
| Feature | ROBOR | IRCC |
|---|---|---|
| Recalculation frequency | daily (quotation) | quarterly |
| Calculation base | interbank rates | deposit rates |
| Volatility | high | low |
| Lag behind the market | immediate | 3-6 months |
| Applies to new loans | no (since 2019) | yes |
| Early repayment fee | variable | zero |
When a variable rate makes sense
A fixed rate protects against increases but starts higher. Variable IRCC starts lower, yet leaves the borrower exposed if inflation or BNR policy lifts the index. In 2026, the typical fixed-versus-variable gap on new consumer loans is 1.3-1.8%, so variable is cheaper by that much at signing.
Roman Dumitrescu, former risk analyst at BCR and later consumer credit product manager at ING: “My simple rule for anyone weighing fixed versus variable: under 5 years, go variable on IRCC, you gain from the initial rate gap, and if a big increase comes you can still repay early without penalty, it's free. For a 20-30 year mortgage, fixed for the first 5-7 years then variable is the most reasonable mix. Banks have hybrid products, ask for them specifically.”
Practical scenarios
Personal loan, 4 years: variable IRCC. The initial 1.5% gap means 1,800-2,400 lei saved over the term. Even if the rate rises in the final 18 months, the balance is small, so the impact is small.
Car loan, 6 years: mixed. A bank offering fixed for the first 3 years and variable for the last 3 gives predictability while the balance is large, flexibility toward the end.
Mortgage, 25 years: fixed for the first 5-7 years, then variable. That buys calm early on, when the balance peaks and installments are most vulnerable to shocks.
Can a loan switch from ROBOR to IRCC?
Only through refinancing into a new loan. Banks do not change the reference index of an existing loan. OUG 50/2010 and court rulings on abusive clauses are clear: the index component cannot be modified unilaterally. A borrower who wants IRCC signs a new contract.
Checking the total cost with a calculator comes first, see Refinancing, when it truly pays off. The old variable ROBOR loan's early repayment fee is also zero (it is a variable rate), so the transition is cheap.
How rate changes are announced
Every quarter, the bank sends a written notification (e-mail, letter, or mobile app alert), at least 30 days before the new installment takes effect. Under OUG 50/2010, art. 37, para. 2, it must state the new IRCC, new interest rate, new monthly installment, remaining balance, and new total cost.
A missing notification is a legal breach, reportable to ANPC, see Your rights when taking a loan. The borrower can seek suspension of the new installment until official communication.

Frequently asked questions
Where is the current IRCC published? On bnr.ro, under “Indicele de referință pentru creditele acordate consumatorilor”. It appears within the first 5 working days of each quarter.
Why does IRCC differ from the BNR rate? Different indices. The BNR rate is the monetary policy rate; IRCC is the average of deposit rates, with a one-month lag. BNR policy influences IRCC, but not directly.
Can the bank's margin still change? Not during the contract. The margin is fixed, signed once. Only IRCC moves, quarterly.
Can IRCC be locked at today's value? Yes, by refinancing into a fixed rate. The bank will offer one above the current IRCC + margin — the price of predictability. Run the numbers on good and bad scenarios first.
Updated after the BNR announcement of 15 May 2026: IRCC for the third quarter is 5.67%, slightly up from 5.42% the quarter before.
IRCC history: what the index has done since 2019
At its introduction in May 2019, IRCC stood at 2.36%. It climbed gradually with post-pandemic inflation, hitting 5.98% in Q3 2023, the highest level in its short history. A slow descent followed as the BNR eased the policy rate: Q4 2024 closed at 5.71%, Q1 2025 at 5.52%, Q2 at 5.42%, Q3 at 5.67%.
The current pattern, oscillation around 5.4-5.7%, follows from inflation settling at roughly 4.2-4.8% and the BNR holding its base rate at 6.5%. For an IRCC borrower, installments now move 8-15 lei per quarter on a typical amount, not the 80-150 lei of 2022.
Practical traps
1) Confusing the margin with the total rate. Adverts say “IRCC + 2.9% margin”. Many read 2.9% and start calculating. The real rate is the sum, so at IRCC 5.67% and a 2.9% margin the borrower pays 8.57%, not 2.9%.
2) An oversized margin at negotiation. Standard bank margins sit between 2.4% and 4.2% in 2026, by product and client profile. An offer above 4% deserves a question: why? Often it signals a profile perceived as risky, fixable before signing (see How to raise your credit score).
3) Simulator miscalculations. Some bank simulators use outdated IRCC values; compare the simulation's value with the one on bnr.ro. Differences of 0.15-0.25% mean 15-30 lei per month on a typical loan.
Five minutes of checking on bnr.ro removes 90% of calculation surprises.
Roman, still in the independent adviser's chair: “I tell my clients to set a calendar reminder for the first day of each quarter, January, April, July, October. Five minutes on bnr.ro tells you where IRCC stands. If it rose 0.25% or more, check the family budget for the coming month. The bank notifies you officially, yes, but being prepared beats being surprised.”
How IRCC is weighted: the formula in detail
BNR Regulation 9/2019 sets out exactly how the index is composed: rates on new deposits attracted by commercial banks authorized in Romania, maturities up to 12 months, in the quarter preceding the calculation. Each rate is weighted by the deposit volume attracted at it; the weighted sum, divided by total volume, gives the average, IRCC for the current quarter.
In practice: a large bank attracting 487 million lei at 4.8% outweighs a small one taking 23 million at 5.9%; IRCC lands close to 4.8%. Not an arithmetic mean, a volume-weighted one. Hence the stability: big banks dominate deposits and rarely reprice, keeping the index smooth.
Who publishes the data and when
The BNR posts the official value on bnr.ro within the first 5 working days of each quarter, typically 5 January, 5 April, 5 July, 5 October. Banks must, under OUG 50/2010 art. 37, recalculate installments and notify clients at least 30 days before the new installment enters into force. So an increase published on 5 April reaches the client's installment on 5-10 May at the earliest.
Cătălin's case: a ROBOR-to-IRCC refinancing in 2021
Cătălin, 44, a HoReCa entrepreneur in Constanța and client of an independent consultancy, held a 187,500 lei mortgage taken in 2017 on 3-month ROBOR + a 2.6% margin. In April 2021, ROBOR oscillated daily between 1.87% and 2.14%, so his effective rate varied between 4.47% and 4.74%. After a month of monitoring, we calculated the previous quarter's weighted average rate: 4.58%. Meanwhile, IRCC for Q2 2021 was 1.28%, and bank margins on new mortgages ran from 2.4% to 3.1%.
The concrete offer from Raiffeisen: refinancing at IRCC + 2.9%, a 4.18% rate. Gap versus the old loan: 0.40% at that moment. On a 162,300 lei balance with 18 years left, that meant around 11,600 lei saved over the term if IRCC stayed flat. Plus zero early repayment fee going forward, the new loan being variable. He signed. In 2023 he confirmed the rate had climbed to 8.42% (IRCC had reached 5.52%), exactly as in the less favorable scenarios we had simulated. Even then, against a ROBOR loan, he sat 0.7% below the market. The refinancing had justified itself.
The official notification: what it must contain
Under OUG 50/2010 art. 37 para. 2, the notification sent before the new installment takes effect must contain: the publication date of the new IRCC, its value, the new rate (IRCC + the client's margin), the effective date, the new monthly installment, the balance at calculation date, and the new total cost if payments run to the end. If any element is missing, the notification is incomplete and, per the 2023 ANPC report p. 14, the client can request suspension of its application until it is corrected.
