Meaning of a Bank and the Banking System

Every economy needs an institution that can safely hold the money people are not spending right now and channel it to people who need to borrow. That institution is the bank. In simple terms, a bank is a financial institution licensed to accept deposits of money from the public and to lend that money to individuals, businesses and governments, while also providing a range of related financial services such as transferring funds, collecting cheques and issuing drafts. For a student working through TS Inter II year Commerce, this chapter on Banking and Insurance builds on the earlier idea of financial institutions as intermediaries between savers and borrowers, and it is one of the more application-heavy chapters because banking and insurance touch almost every commercial transaction in real life.

A bank is fundamentally a trustee of public money. It does not create money out of nothing; it collects small, scattered savings from thousands of depositors and converts them into a large, usable pool of loanable funds. This pooling function is what separates a bank from an ordinary money-lender: a money-lender lends only their own capital, while a bank lends money that ultimately belongs to its depositors, and so a bank carries a much larger responsibility of safety, liquidity and public confidence. Because of this, banking everywhere in the world is a licensed and closely regulated activity, never something a private party may simply start doing on their own.

A banking system is the network of such institutions operating together under the supervision of a central monetary authority. In India this system has a clear hierarchy: a central bank at the top that regulates and supervises, and a wide spread of commercial, cooperative, regional and development banks below it, each serving a different segment of the economy. Understanding this structure is the foundation for everything else this chapter covers — the functions banks perform, how they multiply credit, the modern digital channels through which banking is now delivered, and finally the parallel world of insurance, which manages the risks that banking and every other economic activity are exposed to.
