What is a bank bill?

Copy link to section

A bank bill, also known as a banker’s acceptance, is a short-term debt instrument issued by a bank to meet its immediate funding needs. These bills are essentially promissory notes guaranteeing the payment of a specified amount at a future date, usually ranging from 30 to 180 days. Bank bills are commonly used in money markets for short-term financing and are considered low-risk investments due to the issuing bank’s backing.

Understanding bank bills in detail

How they work: A bank bill is created when a bank accepts responsibility for paying a specified amount of money to the holder of the bill at a future date. The bank may issue these bills for various purposes, such as managing liquidity, financing trade transactions, or providing short-term loans to businesses. Investors purchase these bills at a discount to their face value and receive the full face value at maturity, the difference representing the interest earned.

Types of bank bills:

  • Discounted bank bills: These are sold to investors at a price lower than their face value, and the investor receives the face value at maturity. The difference between the purchase price and the face value is the investor’s return.
  • Interest-bearing bank bills: These bills pay interest periodically during their term, similar to traditional bonds, and return the face value at maturity.

Importance of bank bills

Bank bills are crucial tools for banks and investors in managing short-term financial needs and liquidity. For banks, issuing bank bills provides a flexible and efficient way to raise funds quickly. For investors, bank bills offer a relatively safe investment with predictable returns, often higher than those of savings accounts or other short-term deposits.


  • Low risk: Bank bills are backed by the issuing bank, making them a low-risk investment.
  • Liquidity: These instruments are highly liquid, allowing investors to buy and sell them easily in the secondary market.
  • Attractive returns: Bank bills typically offer higher returns compared to traditional savings accounts, making them attractive for investors seeking short-term gains.


  • Limited return: While safer than many other investments, the returns on bank bills are generally lower compared to higher-risk investment options.
  • Interest rate risk: The value of bank bills can be affected by changes in interest rates, potentially impacting their attractiveness in the market.

Real-world application of bank bills

Trade finance: One of the most significant applications of bank bills is in international trade. Exporters often prefer to receive bank bills as payment for goods shipped overseas. This allows them to convert the bill into cash immediately by selling it in the money market, thus receiving payment quicker than waiting for the importer to pay directly. The importer, in turn, gets additional time to sell the goods and generate revenue before settling the bill.

Liquidity management: Corporations and banks use bank bills to manage their short-term liquidity needs. For instance, a company might issue bank bills to raise quick funds to cover unexpected expenses or to take advantage of a business opportunity that requires immediate capital. Banks use these instruments to balance their daily cash flow needs and ensure they have sufficient liquidity to meet withdrawal demands and other obligations.

Investment vehicles: Investors, including mutual funds, pension funds, and individual investors, use bank bills as part of their investment portfolio to manage risk and maintain liquidity. The short-term nature of bank bills makes them a suitable option for parking funds temporarily while earning a higher return than traditional savings accounts.
