A financial transaction is an agreement, or communication, carried out between a buyer and a seller to exchange an asset for payment.

It involves a change in the status of the finances of two or more businesses or individuals. The buyer and seller are separate entities or objects, often involving the exchange of items of value, such as information, goods, services, and money. It is still a transaction if the goods are exchanged at one time, and the money at another. This is known as a two-part transaction: part one is giving the money, part two is receiving the goods.

A financial transaction always involves one or more financial asset. Either buyer or seller can initiate such a transaction, hence one is the originator/initiator and the other is the responder. From liquidity point of view, one is the liquidity provider, the other party is the liquidity consumer. The liquidity provider is also called offer and the liquidity consumer is also called taker. While bidder and asker are much more confusing. Some people use both bid & ask for liquidity provision, while some other people use offer & ask for liquidity provision.


In ancient times non-financial transactions were commonly conducted through systems of credit, in which goods and services were exchanged for a promise of future recompense. Credit has certain disadvantages, including the requirement that traders or their intermediaries trust one another, or trust that authorities exist who can be relied on to enforce agreements. Debts must eventually be settled either with goods or by payment of money, a substance of agreed value such as gold and silver.

Systems of credit are evident throughout recorded history and from archeology. By contrast little evidence has been found of widespread use of pure barter, where traders meet face to face and transactions are completed in a single swap.

As cities, states, and empires were established, coins and other compact forms of specie were minted or printed as fiat money with set values, permitting the accumulation of assets that would not deteriorate over time as goods might and that had the relatively secure backing of a government which could adjust value by producing more or less of the currency. As fixed currencies were gradually replaced by floating currencies during the 20th century, and as the recent development of computer networks made electronic money possible, financial transactions have rapidly increased in speed and complexity.



This is the most common type of financial transaction. Goods or services are exchanged for money. This transaction results in a decrease in the finances of the purchaser and an increase in the benefits of the sellers.


This is a slightly more complicated transaction than others in which the lender gives a single large amount of money to the borrower now in return for many smaller repayments of the borrower to the lender over time, usually on a fixed schedule. The smaller delayed repayments usually add up to more than the first large amount. The difference in payments is called interest. Here, money is given for not any specific reason.


This is a combined loan and purchase in which a lender gives a large amount of money to a borrower for the specific purpose of purchasing a very expensive item (most often a house, car, gold etc). As part of the transaction, the borrower usually agrees to give the item (or some other high value item) to the lender if the loan is not paid back on time. This guarantee of repayment is known as collateral.

Bank account[edit]

A bank is a business that is based almost entirely on financial transactions. In addition to acting as a lender for loans and mortgages, banks act as a borrower in a special type of loan called an account. The lender is known as a customer and gives unspecified amounts of money to the bank for unspecified amounts of time. The bank agrees to repay any amount in the account at any time and will pay small amounts of interest on the amount of money that the customer leaves in the account for a certain period of time. In addition, the bank guarantees that the money will not be stolen while it is in the account and will reimburse the customer if it is. In return, the bank gets to use the money for other financial transactions as long as they hold it.

Credit card[edit]

This is a special combination of a purchase and a loan. The seller gives the buyer the good or item as normal, but the buyer pays the seller using a credit card. In this way, the buyer is paying with a loan from the credit card company, usually a bank. The bank or other financial institution issues credit cards to buyers that allow any number of loans up to a certain cumulative amount. Repayment terms for credit card loans, or debts vary, but the interest is often extremely high. An example of common repayment terms would be a minimum payment of the greater of $10 or 3% every month and a 15–20% interest charge for any unpaid loan amount. In addition to interest, buyers are sometimes charged a yearly fee to use the credit card.

In order to collect the money for their item, the seller must apply to the credit card company with a signed receipt. Sellers usually apply for many payments at regular intervals. The seller is also charged a fee of normally 1–3% of the purchase price by the credit card company for the privilege of accepting that brand of credit card for purchases.

Thus, in a credit card purchase, the transfer of the item is immediate, but all payments are delayed. The credit card holder receives a monthly account of all transactions. The billing delay may be long enough to defer a purchase payment to the bill after the next one.

Debit card[edit]

This is a special type of purchase. The item or good is transferred as normal, but the purchaser uses a debit card instead of money to pay. A debit card contains an electronic record of the purchaser's account with a bank. Using this card, the seller is able to send an electronic signal to the buyer's bank for the amount of the purchase, and that amount of money is simultaneously debited from the customer's account and credited to the account of the seller. This is possible even if the buyer or seller use different financial institutions. Currently, fees to both the buyer and seller for the use of debit cards are fairly low because the banks want to encourage the use of debit cards. The seller must have a card reader set up in order for such purchases to be made. Debit cards allow a buyer to have access to all the funds in his account without having to carry the money around. It is more difficult to steal such funds than cash, but it is still done. See also skimming and shoulder surfing.
