Digital Technologies Reshape Global Trade and Development – But Barriers Must Fall

In 1992, the entire global internet carried roughly 100 gigabytes of data per day. Today, that same volume flows every millisecond. Internet traffic now exceeds 150,000 gigabytes per second, and Google alone processes over 100,000 queries every second. This staggering acceleration is not merely a technological curiosity—it is the engine reshaping global commerce.

Digital technologies have transformed how goods are produced, traded, and consumed. From supply chain optimization to cross-border payments, the digital layer has raised living standards across much of the world. Yet this transformation remains profoundly uneven. The next generation of technologies—5G, the Internet of Things (IoT), blockchain, and quantum computing—holds the potential to turbocharge trade and development further. But that potential will remain unrealized unless two critical challenges are addressed: the vast infrastructure gap between rich and poor nations, and the outdated trade barriers that stifle digital innovation.

The Infrastructure Gap: Why the Global South Lags Behind

Analysts predict that by 2025, more than 30 billion Internet-connected devices will be deployed worldwide. Smart factories will use IoT sensors to monitor production in real time. Blockchain will enable transparent, tamper-proof supply chains. 5G networks will support autonomous vehicles and remote surgery. But these scenarios are unfolding almost exclusively in wealthy nations.

In Sub-Saharan Africa, less than one-third of the population has access to the internet. Broadband penetration in South Asia remains below 40 percent. The deployment of 5G towers, fiber-optic cables, and data centers is concentrated in North America, Europe, and parts of East Asia. Without robust information and communications technology (ICT) infrastructure—reliable broadband, affordable mobile data, sufficient data centers—developing countries cannot participate in the digital trade revolution.

The consequences extend beyond missed economic opportunities. Digital infrastructure is a prerequisite for inclusive growth. It enables farmers to access market prices, students to take online courses, and small businesses to sell globally. The International Telecommunication Union estimates that every 10 percent increase in broadband penetration can boost GDP growth by up to 1.4 percent in developing economies. Yet investment in digital infrastructure remains heavily skewed toward the Global North. Closing this gap requires coordinated public and private investment, technology transfer, and policy frameworks that encourage competition and reduce the cost of deployment.

Trade Barriers: The Unseen Hurdle to Digital Progress

Even when infrastructure exists, trade barriers prevent the free flow of digital goods and services. Tariffs on ICT products—though reduced under previous agreements—still persist in many countries. Non-tariff measures such as technical standards, licensing requirements, and customs procedures add friction. Data localization mandates force companies to store data within national borders, raising costs and fragmenting the global digital ecosystem. These barriers do not just hurt tech companies; they hamper the deployment of technologies essential for sustainable development.

Consider climate technology. Smart grids, energy-efficient buildings, and precision agriculture all rely on digital sensors, data analytics, and connectivity. The ICT sector itself accounts for only about 1.4 percent of global carbon emissions, yet it enables emissions reductions across every other sector. Trade barriers that slow the adoption of digital climate solutions—such as tariffs on solar inverters, smart meters, or IoT sensors—directly undermine efforts to meet the United Nations Sustainable Development Goals (SDGs).

By better aligning global trade rules to foster growth in digital technologies, economic and social benefits can be widely distributed. Unfortunately, the current rulebook was written for a world of physical goods, not data flows and digital services. The World Trade Organization (WTO) has made progress, but much more is needed.

The Success (and Missed Opportunities) of the WTO’s Information Technology Agreement

One of the WTO’s most effective achievements is the Information Technology Agreement (ITA), first concluded in 1996. The ITA eliminated tariffs on a broad range of IT products, including computers, semiconductors, and telecommunications equipment. For signatory countries, the results were dramatic. Trade in IT products soared, domestic IT sectors grew, and consumers gained access to affordable technology. Countries that joined the ITA experienced faster growth in high-tech exports and productivity.

Yet the ITA was never universal. Many developing countries, fearing loss of tariff revenue or protection for nascent industries, chose not to join. Those countries largely missed out. They did not build competitive domestic IT sectors, and their consumers paid higher prices for technology products. Meanwhile, the original ITA’s product coverage has become outdated. It does not include many modern digital goods—such as smart devices, advanced sensors, or software—nor does it cover environmental technologies.

Expanding the ITA: A Pathway to Inclusive Digital Trade

Expanding the WTO’s Information Technology Agreement is needed to foster innovation, reduce costs, and ensure that the benefits of digital trade reach all nations. Specifically, the next iteration of the ITA—sometimes called ITA-3—should include a new category of environmental technologies. Solar panels, wind turbine components, energy storage systems, and smart grid equipment are increasingly digital and IoT-enabled. Eliminating tariffs on these products would lower the cost of climate action and accelerate the transition to a low-carbon economy.

But expansion alone is not enough. The new agreement must also address non-tariff barriers. Data flows, cybersecurity standards, and digital trade facilitation should be part of the package. Developing countries need technical assistance and transition periods to build their own digital capacities. Without such support, the gap between signatories and non-signatories will only widen.

The digital transformation of global trade is not an abstract future—it is happening now. The next decade will determine whether this transformation deepens inequality or becomes a tool for inclusive, sustainable development. Policymakers must act on multiple fronts: invest in digital infrastructure in the Global South, dismantle trade barriers that inhibit technology flows, and update the WTO rulebook to reflect the realities of a data-driven economy.

The evidence is clear. Removing tariffs on ICT products under the original ITA boosted trade and growth for participants. Expanding that success to cover environmental and next-generation technologies can unlock trillions of dollars in economic value while helping meet climate goals. And by prioritizing infrastructure investment in underserved regions, the global community can ensure that no country is left behind in the digital age.

The tools are available: 5G, IoT, blockchain, and quantum computing. But technology alone is not enough. Trade barriers must fall, infrastructure must be built, and international cooperation must be renewed. Only then can digital technologies truly reshape global trade and development for the benefit of all.
