Public Sector Banks and Co-operative Banks: The Complete JAIIB LRAB Guide for 2026

If you are preparing for JAIIB. The topic of public sector banks and co-operative banks is unavoidable. It sits at the heart of the Legal &. Regulatory Aspects of Banking (LRAB) paper. Examiners love it because it tests memory, law, and reasoning together.

Many students lose easy marks here. They confuse the SBI Act with the Nationalisation Acts. They forget the exact shareholding split of Regional Rural Banks. This guide fixes that, once and for all.

We will cover the State Bank of India. Its subsidiaries, Regional Rural Banks, nationalised banks, and co-operative banks. Every legal section is explained simply. So you actually remember it on exam day.

Why Public Sector and Co-operative Banks Matter in LRAB

India's banking sector is not one single block. It is a layered structure built over decades through specific laws. Each layer was created to solve a particular problem.

The State Bank brought scale and trust. Nationalisation spread banking to the masses. RRBs reached the villages. Co-operative banks served local communities. Understanding this story makes the law easy to recall.

For JAIIB candidates, this topic links directly to ownership, governance, and regulation. These are recurring themes across the whole LRAB paper. Mastering it once pays off in many questions.

State Bank of India and Its Subsidiaries

The State Bank of India (SBI) is the oldest. Largest commercial bank in the country. Its legal foundation is unique and frequently tested.

Establishment of the State Bank

SBI was established under Section 3 of the State Bank of India Act 1955. The Act took over the undertaking of the Imperial Bank of India. The goal was to let SBI carry on banking. Other permitted businesses.

Business of the State Bank

The bank's activities are anchored in the Banking Regulation Act. Under Section 5(b) and Section 6(1) of that Act. SBI can conduct banking business and other specified businesses respectively.

Accounts and Audit

SBI must close its books every year on 31st March. Or another date set by the Central Government and RBI. It prepares a balance sheet. A profit and loss account. And a report by the Central Board on its working.

The audit may be done by any person qualified to be a company auditor under Section 141 of the Companies Act 2013. This common audit standard appears across almost every bank type in this topic.

Subsidiary Banks

SBI's subsidiaries have their own rules. Under Section 18 of the Act. Shares of subsidiary banks can be freely transferred. Section 47 empowers SBI to inspect its subsidiary banks.

Rules and Regulations

Law-making power is split clearly. Under Section 62. The Central Government may make rules to fulfil the Act's purpose. Under Section 63, SBI may make regulations, but only after RBI approval.

Regional Rural Banks (RRBs)

Regional Rural Banks are public sector institutions. They are regional in scope and rural in focus. They carry on the commercial banking business for India's villages and farmers.

Origin and Establishment of RRBs

The first RRB was set up in 1975 under the Regional Rural Bank Ordinance. 1975. This ordinance was later replaced by the RRB Act 1976.

Under Section 3 of the RRB Act. The Central Government can establish an RRB. It does so through a notification in the official gazette. At the request of a sponsor bank.

Shareholding Pattern of RRBs

This split is a guaranteed exam favourite. Learn it cold. The ownership of an RRB is shared three ways.

Stakeholder	Shareholding
Central Government	50%
State Government	15%
Sponsor Bank(s)	35%

A simple way to recall it: 50 + 15 + 35 = 100. The Centre holds half. The sponsor bank a third, and the state the rest.

Business and Audit of RRBs

RRBs mainly transact banking business as defined in Section 5(b) of the Banking Regulation Act. They may also do any other business permitted under Section 6(1).

The audit is conducted by a person qualified as a company auditor under Section 141 of the Companies Act 2013. These auditors are appointed after the Central Government's approval.

Nationalised Banks

Nationalised banks changed Indian banking forever. They brought private banks under public ownership in two historic waves.

How Nationalised Banks Were Created

Two laws did the heavy lifting. The Bank Nationalisation Act 1970. The Banking Companies (Acquisition. Transfer of Undertakings) Act 1980 transferred the business of existing private banks to corresponding new banks.

These new banks are popularly known as nationalised banks. The 1970 Act. The 1980 Act are the two pillars you must always pair together.

Board of Directors of Nationalised Banks

Directors are either nominated by the Central Government or elected by shareholders. The nomination follows specific numerical limits, which examiners often test directly.

Type of Director	Number
Whole-time directors	Up to 4
Directors nominated by Central Government	Up to 6
Official director	1
Representative of workmen employees	1
Representative of bank officers	1
Director with expertise in regulation or supervision of commercial banks	1

Additional Directors and Audit

RBI holds a special power here. The Reserve Bank of India can appoint one or more additional directors on the board of a nationalised bank.

The audit follows the now-familiar rule. It is conducted by a person qualified as a company auditor under Section 141 of the Companies Act 2013. Auditors are appointed after the central bank's approval.

Scheme of Management

The Central Government framed two management schemes. These flow from Section 9 of both the 1970 Act and the 1980 Act.

• Nationalised Banks (Management & Miscellaneous Provisions) Scheme, 1970
• Nationalised Banks (Management & Miscellaneous Provisions) Scheme, 1980

Paid-up Capital and Governing Laws

Initially. The whole paid-up capital of nationalised banks was held by the Central Government. Today.

Many have made public share issues. Yet the Central Government still holds the majority. Shares held by the Central Government are freely transferable.

These banks are governed by their own Acts, rules, and schemes. They are also covered by the Banking Regulation Act. As provided in Section 51 of that Act. Always confirm the exact section number on the latest official IIBF notification. As section references can change.

Co-operative Banks

Co-operative banks serve members and local communities. Their legal position is dual and slightly tricky. Which makes them a strong source of exam questions.

Applicability of the Banking Regulation Act

Banks operating in more than one state are registered under the Multi-State Co-operative Societies Act. On top of that. Co-operative banks are regulated by the Banking Regulation Act with certain modifications under Section 56.

The BR Act became applicable to co-operative societies through the Banking Laws (Application to Co-operative Societies) Act. 1965. For this purpose. It covers a state co-operative bank. A central co-operative bank, and a primary co-operative bank.

Paid-up Capital and Reserves

There is a minimum capital threshold. Under Section 11. The minimum paid-up share capital. Reserves to start or carry on banking by a co-operative bank must be at least Rs. 1,00,000.

Restrictions on Loans and Advances

Section 20 of the Banking Regulation Act restricts the loans a co-operative bank can give. These restrictions prevent conflicts of interest and protect depositors.

• Co-operative banks cannot grant loans or advances against their own shares.
• They cannot grant loans or advances to any of their directors.
• They cannot grant unsecured loans to entities where the chairman acts as managing agent.

Liquid Assets, Licensing, and Inspection

Three more rules complete the picture. They mirror the rules for commercial banks, with minor co-operative tweaks.

• Liquid assets: Under Section 24(1), every co-operative bank must maintain liquid assets.
• Licensing: Under Section 22. Every co-operative bank needs a licence from the Reserve Bank of India.
• Inspection: The inspection provisions under Section 35 apply to co-operative banks with minor modifications.

Public Sector Banks vs Co-operative Banks: A Quick Comparison

Students often blur these two categories. This table draws a clean line between them. So you never mix up the governing laws again.

Basis	Public Sector Banks	Co-operative Banks
Core ownership	Government-majority shareholding	Owned by members
Primary law	SBI Act 1955, RRB Act 1976, Nationalisation Acts 1970 & 1980	Co-operative Societies Acts + BR Act (Section 56)
Regulator	RBI and Central Government	RBI and Registrar of Co-operative Societies (dual control)
Main focus	Nationwide commercial banking	Local and community banking
Audit standard	Section 141, Companies Act 2013	As per co-operative law and BR Act provisions

How to Study This Topic and Score Full Marks

Reading is not enough for LRAB. You need a system that locks the section numbers into memory. Here is a method that works for thousands of toppers.

1. Group by bank type. Study SBI, RRBs, nationalised banks, and co-operative banks as four separate blocks.
2. Tag every section number. Write the Act and section on a flashcard. With the rule on the back.
3. Master the numbers. Lock in the RRB 50:15:35 split and the director limits first. As these repeat often.
4. Use memory hooks. Link Section 62 to Rules and Section 63 to Regulations, as shown earlier.
5. Test, then revise. Attempt mock tests after each block to find weak spots fast.
6. Revise weekly. Quickly review all section numbers every week until exam day.

Common Mistakes Students Make

Most lost marks in this topic come from a few repeated errors. Avoid these and you will already be ahead of the crowd.

• Mixing up the Acts. The SBI Act is 1955. Nationalisation is 1970 and 1980. Never swap these years.
• Wrong RRB split. Some write 50:35:15 by reversing the state and sponsor shares. It is 50:15:35.
• Confusing Rules and Regulations. Government makes rules; the bank makes regulations with RBI approval.
• Forgetting Section 56. Co-operative banks follow the BR Act with modifications. Not the plain BR Act.
• Ignoring updates. Section numbers and limits can change. So always confirm on the latest official IIBF notification.
