Automation and Core Banking

In one line

Indian banking moved from a ledger kept at a branch to a single computer record kept for the whole bank, and that change is what made everything in the next four chapters possible.

In the wording a student can write in an exam: the automation of Indian banking proceeded from mechanisation and the introduction of magnetic ink character recognition cheque clearing, through the Rangarajan Committee reports of 1984 and 1989 which set the framework for computerisation, to the adoption of core banking solutions under which all branches of a bank share a single centralised database, so that a customer is a customer of the bank rather than of a branch.

Why the branch ledger had to go

Chapter 300 gave the classical rule and it explains the whole problem. In Joachimson v. Swiss Bank Corporation, [1921] 3 KB 110, the banker's obligation is to repay on demand at the branch where the account is kept. That rule was not a technicality; it was a description of the physical world, in which the customer's account existed as an entry in a ledger at one branch and nowhere else.

Everything followed from that. A customer could operate only at his own branch. A cheque drawn on another city had to travel there physically to be paid, taking weeks. The bank could not know its own total position except by adding up branch returns. And a customer with accounts at two branches of one bank was, for practical purposes, two customers.

Automation dissolved the branch as the unit of banking. Under a core banking solution the account is a record in a central database, and the branch is one of several channels through which the customer reaches it, alongside the ATM, the internet and the telephone.

Three legal consequences follow, and they are what makes this a law chapter rather than a history of machines.

The place of demand loses its meaning. A customer may demand payment anywhere, so Joachimson's rule survives in the textbooks and not at the counter, which chapter 300 records as a criticism.

The bank can see its own exposure. Chapter 530's asset classification is borrower-wise, which is only enforceable if the bank can aggregate a borrower's facilities across branches instantly. Prudential regulation of the modern kind presupposes core banking.

And the record changes its nature. A ledger written by hand and a database entry are different kinds of evidence, which is the subject of the next section.

The stages, and the committees that drove them

Mechanisation, from the 1960s. Accounting machines and ledger posting machines in large branches, which reduced clerical error without changing anything conceptually.

Magnetic ink character recognition, from 1986. The band of numbers along the foot of a cheque, encoding the bank, branch, account and instrument number in a form a machine can read, which made mechanised clearing possible and is the ancestor of the truncation chapter 390 works.
