5 RBI Rules Every Bank Exam Aspirant Must Know in 2026

It is 9 PM. Your exam is in six weeks. Someone in your study group just asked about CRILC and the room went silent. This is the page that ends that silence — five RBI rules, decoded in plain English, with the exact numbers examiners love.

What Exactly Is 'Banking Current Affairs' and Why Do Exams Love It?

Banking current affairs is the living part of your syllabus. Static subjects — like CRR and SLR — never change. Current affairs does. It is the RBI circular from last month, the new payment system, the penalty on a bank. Exam setters use it to filter out candidates who only memorise textbooks.

For the JAIIB, CAIIB, IBPS, SBI PO, and RBI Grade B exams, roughly 10–15% of the General Awareness section comes from banking current affairs. The good news: it is the most predictable part of the paper. The RBI publishes everything. You just need to know where to look and what to remember.

This guide covers the five topics the Banking Awareness Guide 2026 flags as highest-yield: KYC Master Direction, BBPS, CRILC, Account Aggregator, and NACH vs UPI e-mandates.

What Is the RBI Master Direction on KYC and Who Must Comply?

The RBI Master Direction on KYC (Know Your Customer) is the rulebook that tells every regulated entity exactly how to verify who you are before giving you a product. It was first issued in 2016 and is updated regularly.

Who must comply? Every bank, every NBFC (non-banking financial company), every payment system operator, every credit information company, and even digital lending apps that are regulated by the RBI. If the RBI licenses it, the KYC Master Direction applies to it.

What does it actually say? Three things matter for exams:

• Customer Due Diligence (CDD): The bank must know who you are, what you do, and where your money comes from.
• Risk categorisation: Banks must classify you as low, medium, or high risk. A salaried person is low risk. A politically exposed person is high risk.
• Periodic updates: Your KYC must be refreshed every 2, 8, or 10 years depending on your risk category.

For the exam, remember this one-liner: KYC is not a one-time form. It is a continuous obligation on the bank to know its customer.

Explain the Bharat Bill Payment System (BBPS) and Who Operates It

BBPS is India's one-stop bill payment network. Electricity, water, gas, DTH, insurance premiums, school fees — you can pay them all through one platform. Before BBPS, you had to go to each biller's own website or app. Now, one app can handle everything.

Who operates it? NPCI Bharat BillPay Ltd (NBBL), a wholly-owned subsidiary of the National Payments Corporation of India (NPCI). The RBI regulates it under the Payment and Settlement Systems Act, 2007.

How it works: There are two sides. On one side are Biller Operating Units (banks and NBFCs that onboard billers). On the other are Customer Operating Units (the apps you use to pay). NBBL sits in the middle, routing the payment and settling it.

For the exam, remember: BBPS is interoperable — any app can pay any biller. That is its superpower.

What Are the CRILC and Wilful Defaulter Reporting Thresholds in India?

CRILC stands for Central Repository of Information on Large Credits. It is a database maintained by the RBI that collects information on all large borrower accounts. Banks must report every account where the total exposure is ₹5 crore or more.

Why does this matter? When a borrower defaults on one bank, other banks need to know. CRILC is the early warning system. It helps banks spot stress before it becomes a full-blown default.

What is a wilful defaulter? The RBI defines a wilful defaulter as a borrower who:

• Has the capacity to repay but does not repay, or
• Has diverted the loan funds for purposes other than what they were borrowed for, or
• Has siphoned off funds so that the money is not available with the company, or
• Has sold off assets without the bank's permission.

Once declared a wilful defaulter, the borrower cannot get new loans from any bank. The list is shared across the system. For the exam, the number to remember is ₹5 crore — that is the reporting threshold.

How Does the RBI Account Aggregator Consent Framework Work?

The Account Aggregator (AA) framework is India's answer to data sharing. It lets you share your financial data — bank statements, mutual fund holdings, insurance policies — with a lender or advisor, without giving them your passwords.

How it works in four steps:

• You give consent: You decide what data to share, with whom, and for how long.
• The AA fetches it: The Account Aggregator (a licensed NBFC) pulls your data from the bank or mutual fund.
• Data flows one way: The data goes from the provider to you or your chosen recipient. The AA itself cannot see or store your data.
• You can revoke: Your consent is revocable at any time. The moment you withdraw it, the sharing stops.

This is a game-changer for loans. Instead of submitting three months of bank statements manually, you just give consent and the lender gets the data in seconds. For the exam, remember: consent is the cornerstone. No consent, no data sharing.

What Is the NACH / e-Mandate System and How Does It Differ from UPI e-Mandate?

Both NACH e-mandates and UPI e-mandates are for recurring payments. Your SIP, your insurance premium, your EMI — all of these are recurring. But the plumbing underneath is different.

NACH (National Automated Clearing House): This is the older system, run by NPCI. It works on a debit instruction model. You sign a mandate with your bank, and on the due date, the bank automatically debits your account. It is batch-processed — payments happen in bulk at specific times of the day. It is reliable but not instant.

UPI e-mandate: This is the newer system. It works on UPI (Unified Payments Interface). You approve a mandate on your UPI app, and on the due date, the payment is processed instantly. It is real-time, and you can see it happen on your phone.

Key difference for exams:

• NACH is for bank-account-to-bank-account debits, processed in batches.
• UPI e-mandate is for UPI-app-based debits, processed in real-time.

Both are regulated by the RBI. Both require your explicit consent. The difference is speed and the interface.

How to Prepare for Banking Current Affairs in 30 Minutes a Day

You do not need to read every newspaper. You need a system. Here is a 30-minute daily routine that works:

• Minutes 0–10: Read the RBI's daily press releases. Just the headlines. If it mentions a rate, a penalty, or a new circular, read the full release.
• Minutes 10–20: Read one deep-dive explainer. This page, or the Banking News India section, gives you the context that newspapers skip.
• Minutes 20–30: Write down three facts — one number, one name, one date — on a sticky note. Stick it on your wall. Review it before bed.

For the exam, focus on what changed, not what is static. The RBI repo rate history is static. The full timeline from 2000 to 2026 is worth knowing, but the current rate is what gets asked.

Where to Find Official Banking Current Affairs (and Avoid Fake News)

There is a lot of misinformation about banking rules floating around WhatsApp. Here is where the truth lives:

• RBI website (rbi.org.in): All circulars, master directions, and press releases. This is the ground truth.
• NPCI website (npci.org.in): For payment systems like UPI, NACH, and BBPS.
• PIB (pib.gov.in): For government schemes related to banking, like PMJDY.

If a number appears in a coaching institute's PDF but not on the RBI website, treat it as unverified. For exam purposes, the RBI website is the only source that matters. If you are preparing for the RBI Grade B exam, the exam pattern guide will help you allocate your time across sections.
