Multinational manufacturers

Moving back to America

The dwindling allure of building factories offshore

“WHEN clients are considering opening another manufacturing plant in China, I’ve started to urge them to consider alternative locations,” says Hal Sirkin of the Boston Consulting Group (BCG). “Have they thought about Vietnam, say? Or maybe [they could] even try Made in USA?” When clients are American firms looking to build factories to serve American customers, Mr Sirkin is increasingly likely to suggest they stay at home, not for patriotic reasons but because the economics of globalisation are changing fast.

Labour arbitrage—taking advantage of lower wages abroad, especially in poor countries—has never been the only force pushing multinationals to locate offshore, but it has certainly played a big part. Now, however, as emerging economies boom, wages there are rising. Pay for factory workers in China, for example, soared by 69% between 2005 and 2010. So the gains from labour arbitrage are starting to shrink, in some cases to the point of irrelevance, according to a new study by BCG.

“Sometime around 2015, manufacturers will be indifferent between locating in America or China for production for consumption in America,” says Mr Sirkin. That calculation assumes that wage growth will continue at around 17% a year in China but remain relatively slow in America, and that productivity growth will continue on current trends in both countries. It also assumes a modest appreciation of the yuan against the dollar.

The year 2015 is not far off. Factories take time to build, and can carry on cranking out widgets for years. So firms planning today for production tomorrow are increasingly looking close to home. BCG lists several examples of companies that have already brought plants and jobs back to America. Caterpillar, a maker of vehicles that dig, pull or plough, is shifting some of its excavator production from...
