Soaring flows of data and information now generate more economic value than the global goods trade.

Conventional wisdom says that globalization has stalled. But although the global goods trade has flattened and cross-border capital flows have declined sharply since 2008, globalization is not heading into reverse. Rather, it is entering a new phase defined by soaring flows of data and information.

Exploding digital flows in a deeply connected world

Remarkably, digital flows—which were practically nonexistent just 15 years ago—now exert a larger impact on GDP growth than the centuries-old trade in goods, according to a new McKinsey Global Institute (MGI) report, Digital globalization: The new era of global flows. And although this shift makes it possible for companies to reach international markets with less capital-intensive business models, it poses new risks and policy challenges as well.

The world is more connected than ever, but the nature of its connections has changed in a fundamental way. The amount of cross-border bandwidth that is used has grown 45 times larger since 2005. It is projected to increase by an additional nine times over the next five years as flows of information, searches, communication, video, transactions, and intracompany traffic continue to surge. In addition to transmitting valuable streams of information and ideas in their own right, data flows enable the movement of goods, services, finance, and people. Virtually every type of cross-border transaction now has a digital component.

Trade was once largely confined to advanced economies and their large multinational companies. Today, a more digital form of globalization has opened the door to developing countries, to small companies and start-ups, and to billions of individuals. Tens of millions of small and midsize enterprises worldwide have turned themselves into exporters by joining e-commerce marketplaces such as Alibaba, Amazon, eBay, Flipkart, and Rakuten. Approximately 12 percent of the global goods trade is conducted via international e-commerce. Even the smallest enterprises can be born global: 86 percent of tech-based start-ups surveyed by MGI report some type of cross-border activity. Today, even the smallest firms can compete with the largest multinationals.
