Digital communication technology: Meaning, Criticisms & Real-World Uses

What Is Digital Communication Technology?

Digital communication technology in finance refers to the systems, protocols, and devices that enable the electronic exchange of information, data, and instructions within the financial sector. This encompasses the infrastructure that facilitates everything from electronic trading to mobile banking. It is a foundational element of Financial Technology, which leverages computing and communication advancements to improve and automate financial services. The widespread adoption of digital communication technology has fundamentally reshaped how financial markets operate, enhancing speed, efficiency, and accessibility for participants globally.

History and Origin

The integration of digital communication technology into finance began to accelerate significantly in the latter half of the 20th century. Before this era, financial transactions primarily relied on physical presence and voice communication on trading floors. A major turning point arrived with the development of electronic communication networks. For instance, NASDAQ, established in 1971, emerged as one of the world's first electronic stock exchanges, initiating a transition from traditional floor trading to electronic systems.⁵, This innovation allowed for more efficient and faster trade execution, reduced errors, and provided real-time market data.⁴

The evolution continued with the spread of the internet in the 1990s and 2000s, making online trading more accessible to individual investors. Regulatory bodies, such as the U.S. Securities and Exchange Commission (SEC), adapted their oversight to accommodate these technological shifts, recognizing the need to integrate electronic trading platforms into the national market system.,³ The continuous advancement of digital communication technology has since underpinned the rise of modern financial systems, enabling global interconnectedness and transforming the landscape of investment and financial services.

Interpreting the Digital Communication Technology Landscape

In the context of finance, interpreting the landscape of digital communication technology involves understanding its impact on operational efficiency, market reach, and competitive dynamics. The effectiveness of this technology is often measured by factors such as transaction speed, data security, and system reliability. For example, faster communication channels allow for quicker order execution and real-time data dissemination, which are crucial for participants in volatile financial markets.

Furthermore, the adoption rate and sophistication of digital communication technology can indicate a firm's or market's readiness for innovation and its capacity to engage in advanced financial activities, such as algorithmic trading. Regulators and market participants continuously evaluate these technologies to ensure fair and orderly markets while fostering innovation. Analyzing the underlying digital communication technology helps to assess the infrastructure that supports global capital markets and cross-border financial flows.

Hypothetical Example

Consider a global investment firm, "Diversify Global Investments," that uses advanced digital communication technology to manage its clients' portfolios. An individual investor, Sarah, living in New York, wants to purchase shares of a company listed on the London Stock Exchange.

Order Placement: Sarah uses Diversify Global Investments' online trading platform on her smartphone to place a buy order. This platform leverages digital communication technology to securely transmit her order instantly to the firm's central systems.
Order Routing: The firm's internal systems, powered by high-speed digital communication networks, route Sarah's order to its broker-dealers in London.
Market Execution: The London broker-dealer's system, connected to the London Stock Exchange via digital communication channels, executes the trade almost instantaneously at the prevailing market price. This relies on the exchange's digital infrastructure for matching buy and sell orders.
Confirmation and Settlement: A confirmation of the trade is sent back through the digital communication channels to Diversify Global Investments, which then updates Sarah's portfolio online and sends her an immediate notification. The underlying payment systems then handle the settlement process electronically, further demonstrating the role of digital communication technology in streamlining complex global transactions.

This entire process, which might have taken hours or even days in a pre-digital era, is completed in seconds, showcasing the efficiency driven by digital communication technology.

Practical Applications

Digital communication technology is ubiquitous across various aspects of finance:

Electronic Trading: It underpins modern trading platforms, enabling high-frequency trading, automated order execution, and real-time market data dissemination across global exchanges. This technology directly impacts market liquidity and price discovery.
Retail Banking: Mobile banking apps, online transfers, and automated teller machines (ATMs) are direct applications of digital communication technology, providing consumers with convenient access to financial services.
Payments and Remittances: Cross-border digital payments and remittance services rely on secure and efficient digital communication networks to facilitate rapid transfer of funds globally. The International Monetary Fund (IMF) highlights how digital financial services have been a key driver of financial inclusion, especially in emerging markets.²
Financial Market Infrastructure: Clearinghouses and settlement systems utilize sophisticated digital communication technology to ensure the secure and timely transfer of securities and funds between parties.
Data Analysis and Reporting: The ability to collect, transmit, and process vast amounts of financial data in real-time for data analysis and regulatory reporting is a core function enabled by advanced digital communication technology.

Limitations and Criticisms

While transformative, digital communication technology in finance also presents several limitations and criticisms. A primary concern is cybersecurity. The increasing reliance on interconnected digital systems makes financial institutions vulnerable to cyberattacks, including data breaches, ransomware, and denial-of-service attacks. Such incidents can lead to significant financial losses, reputational damage, and systemic disruptions. The IMF's Global Financial Stability Report consistently identifies cyber risk as an acute threat to macrofinancial stability, particularly given the sector's high concentration and interconnectedness.¹

Another limitation involves the potential for digital divides, where populations with limited access to technology or digital literacy may be excluded from the benefits of modern financial services, thereby hindering broader financial inclusion efforts. There are also criticisms regarding the speed and complexity enabled by digital communication technology, which can contribute to flash crashes or exacerbate market volatility due to rapid, automated trading. Furthermore, the reliance on third-party technology providers introduces supply chain risks, where a vulnerability in one provider's system could impact numerous financial institutions. Effective risk management and robust financial regulation are crucial to mitigate these inherent drawbacks.

Digital Communication Technology vs. Fintech

While closely related, digital communication technology and Fintech are distinct concepts. Digital communication technology refers to the fundamental infrastructure and tools—such as networks, protocols, and hardware—that enable the electronic transmission of data and information. It is the underlying means by which digital information travels.

In contrast, Fintech (Financial Technology) is a broader term that encompasses the application of technology to improve and automate financial services. This includes a wide array of innovations such as mobile banking applications, online lending platforms, blockchain technology, and robo-advisors. While Fintech heavily relies on digital communication technology to function, the latter is merely a component or an enabler for the diverse solutions and services that Fintech offers. Think of digital communication technology as the roads and bridges, and Fintech as the vehicles and transportation services that use them to deliver financial value.
