RBI New EIR Accounting Rules will change how banks calculate and recognise interest income from loans and investments starting April 1, 2027.
The Reserve Bank of India (RBI) has introduced the Effective Interest Rate (EIR) method as part of a broader banking accounting reform that also includes a forward-looking Expected Credit Loss (ECL) framework.
The new rules are expected to change how banks account for interest, loan values and credit losses.
Banks will need to update their accounting systems, review existing processes and prepare for the transition before the implementation deadline.
The changes will initially apply to new loans and financial assets originated from April 1, 2027.
Existing loans will also gradually move to the EIR framework, with banks required to complete the transition by March 31, 2030.
RBI New EIR Accounting Rules: What Will Change?
Under the new framework, banks will calculate interest income using the Effective Interest Rate method instead of relying only on the contractual interest rate.
The EIR method considers the expected future cash flows of a financial instrument and its carrying value.
It also takes relevant transaction costs, premiums and discounts into account when calculating the effective return.
This means that banks will recognise interest income more comprehensively over the life of a loan or financial asset.
For example, if a bank purchases a bond with a face value of Rs 100 for Rs 95, the difference of Rs 5 represents a discount.
Under the EIR method, this discount is included in the effective return and recognised over the bond’s life rather than being ignored when calculating the contractual interest rate.
Similarly, if a bank purchases a bond at a premium, that additional cost will also be reflected in the effective yield calculation.
The objective is to improve consistency and transparency in how banks report interest income.
Which Banks Will Be Covered Under the New Rules?
The revised directions will apply to commercial banks covered by the RBI framework, including State Bank of India and other eligible banking companies.
The directions exclude Small Finance Banks, Payment Banks and Local Area Banks from this particular framework.
Banks will have to review their loan accounting, financial reporting procedures and technology systems to ensure that the new method is implemented correctly.
The transition will also require coordination between banking, finance, treasury and technology departments.
What Happens to Existing Bank Loans?
The RBI has provided a transition period for loans that are already outstanding before the new rules take effect.
For loans originated on or after April 1, 2027, banks will have to follow the EIR method from the beginning.
However, loans outstanding as of March 31, 2027, can continue to use the existing contractual interest rate for income recognition during the transition period.
Banks must bring all these existing loans under the EIR framework no later than March 31, 2030.
This means that the transition will happen in stages rather than requiring every existing loan to move to the new accounting method immediately in April 2027.
 RBI Also Introduces Expected Credit Loss Framework
Along with the EIR method, the RBI has introduced an Expected Credit Loss framework to change how banks calculate provisions for potential loan losses.
Under the earlier incurred-loss approach, banks generally recognised provisions when evidence of a loss or deterioration emerged.
The new ECL approach requires banks to estimate possible future credit losses by considering changes in credit risk.
The framework divides financial assets into three stages.
Stage 1 covers loans and financial assets without a significant increase in credit risk. Banks must maintain provisions based on 12-month expected credit losses.
Stage 2 covers assets where credit risk has increased significantly since initial recognition. Banks must calculate provisions based on lifetime expected credit losses.
Stage 3 covers credit-impaired financial assets, which also require lifetime expected credit loss provisions.
This approach is intended to help banks recognise potential credit problems earlier and maintain appropriate financial buffers.
Importantly, the RBI has retained the existing 90-day overdue criterion for classifying a loan as a non-performing asset (NPA).
 How Will the New Accounting Rules Affect Banks?
The new accounting framework will require banks to make changes to their financial reporting and internal systems.
Banks will need to upgrade accounting software, test new calculations and review how interest income, transaction costs and loan values are recorded.
The impact on individual banks may differ depending on their loan portfolios, investment holdings and existing accounting practices.
The EIR method may also change the timing and distribution of reported interest income because premiums, discounts and eligible transaction costs will be reflected over the life of financial instruments.
However, these are accounting and reporting changes.
They do not automatically mean that banks will increase or decrease the interest rates charged to customers on their loans.
For borrowers, the contractual terms of an existing loan will remain governed by the applicable loan agreement and relevant banking rules.
 When Will the New RBI Rules Become Effective?
The RBI issued its final directions on April 27, 2026, with April 1, 2027, set as the implementation date.
Banks will have to prepare for the new framework before that deadline.
The first reporting under the ECL framework will be based on the financial position as of June 30, 2027.
Banks will also have to provide comparative financial information under the new framework beginning March 31, 2028.
The changes represent an important shift in India’s banking accounting system.
By introducing EIR-based interest recognition and forward-looking credit loss provisioning, the RBI aims to improve transparency, consistency and credit risk management across the banking sector.
