Transaction
Overview
A transaction (거래, Transaction) refers to an economic act of exchanging value—such as goods, services, financial assets, or information—between two or more parties. Transactions are the basic unit of a market economy, coordinating resource allocation through the price mechanism, and form the foundation of all economic activities. Transactions exist in various forms, from simple barter to complex financial derivatives trading, and are conducted within a framework of legal contracts and trust.

Types of Transactions
Transactions are broadly divided into spot transactions and futures transactions. Spot transactions involve immediate delivery and settlement, while futures transactions promise delivery and settlement at a specific future point. Additionally, based on the subject of the transaction, they are classified into commodity transactions, financial transactions, service transactions, and information transactions. With the development of e-commerce, the proportion of online transactions has surged, and digital asset trading on cryptocurrency exchanges has also established itself as a new type.
Components of a Transaction
Every transaction includes at least three elements: the parties involved (seller and buyer), the subject of the transaction (goods, services, assets, etc.), and the exchange conditions (price, quantity, delivery timing, payment method, etc.). In modern economies, intermediaries (brokers, exchanges, banks), payment systems (credit cards, electronic transfers, blockchain), and legal regulations (contract law, securities law) additionally intervene to ensure transaction safety and efficiency. Transaction costs include search costs, negotiation costs, and enforcement costs generated by these elements, and are an important concept in economics.
Historical Development of Transactions
In early human history, barter was the primary method of transaction, but the emergence of money dramatically improved transaction efficiency. During the Middle Ages, trade transactions developed around Mediterranean commerce, and in the 17th century, the Dutch East India Company pioneered stock trading. The 20th century saw the introduction of credit cards and electronic payment systems, and in the 21st century, the internet and blockchain technology are revolutionizing transaction methods. In particular, following the publication of the Bitcoin whitepaper in 2008, cryptocurrency trading has enabled trustworthy transactions without central authorities.
Economic Functions of Transactions
Transactions enhance the efficiency of resource allocation, promote division of labor and specialization, and drive economic growth. Adam Smith argued, through the concept of the 'invisible hand,' that free transactions benefit society as a whole. Transactions also perform a price discovery function, providing information to market participants and enabling risk sharing. Transactions in financial markets supply liquidity and support corporate financing.
Legal Aspects of Transactions
Transactions are generally legally protected through contracts. A contract is formed by the agreement of offer and acceptance, specifying the rights and obligations of the parties. The validity of a transaction depends on the parties' legal capacity, the legality of the purpose, and the genuineness of consent. Unfair trade practices (fraud, duress, mistake) can render a contract void or voidable. Modern legal systems ensure the fairness and safety of transactions through consumer protection, antitrust laws, and financial regulations.
Ethical Considerations in Transactions
Transactions go beyond mere economic exchange and involve ethical dimensions. The fair trade movement aims to pay just compensation to producers in developing countries and is linked to corporate social responsibility (CSR). Information asymmetry can cause ethical issues in transactions, and disclosure obligations and regulations are established to address this. Additionally, trust in transactions is essential for long-term relationships and market stability.
Recent Trends
As of 2024-2025, the transaction environment is changing along two axes: digital transformation and regulatory tightening. First, the use of blockchain-based decentralized exchanges (DEXs) is increasing, expanding peer-to-peer (P2P) transactions without intermediaries. Second, the introduction of central bank digital currencies (CBDCs) is accelerating, with pilot operations of China's digital yuan and Europe's digital euro. Third, artificial intelligence (AI) is being utilized in trading strategies and risk management, with algorithmic trading accounting for over 70% of transactions. Fourth, ESG (Environmental, Social, Governance) criteria have become an important factor in transaction decision-making, increasing demand for sustainable transactions. Fifth, due to global supply chain restructuring and geopolitical risks, trade transactions are diversifying and regionalizing. Sixth, with the spread of micropayments and the subscription economy, transaction units are becoming more granular.
