“Global flows have been a common thread in economic growth for centuries, since the days of the Silk Road, through the mercantilist and colonial periods and the Industrial Revolution. But today, the movement of goods, services, finance, and people has reached previously unimagined levels. Global flows are creating new degrees of connectedness among economies—and playing an ever-larger role in determining the fate of nations, companies, and individuals; to be unconnected is to fall behind. MGI’s James Manyika and Susan Lund discuss trends in cross-border exchanges of goods, services, finance, people, and data and information. Flows of goods, services, and finance reached $26 trillion in 2012, or 36 percent of global GDP, 1.5 times the level in 1990. Now, one in three goods crosses national borders, and more than one-third of financial investments are international transactions. In the next decade, global flows could triple, powered by rising prosperity and participation in the emerging world and by the spread of the Internet and digital technologies. Our scenarios show that global flows could reach $54 trillion to $85 trillion by 2025, more than double or triple their current scale. A new McKinsey Global Institute (MGI) report, Global flows in a digital age: How trade, finance, people, and data connect the world economy, examines the inflows and outflows of goods, services, finance, and people, as well as the data and communication flows that underlie them all, for 195 countries around the world.”
