According to the latest IMF official forecasts, China’s economy will surpass that of America in real terms in 2016.
The IMF in its analysis looks beyond exchange rates to the true, real terms picture of the economies using “purchasing power parities.” That compares what people earn and spend in real terms in their domestic economies.
Under PPP, the Chinese economy will expand from $11.2 trillion this year to $19 trillion in 2016. Meanwhile the size of the U.S. economy will rise from $15.2 trillion to $18.8 trillion. That would take America’s share of the world output down to 17.7%, the lowest in modern times. China’s would reach 18%, and rising.
Just 10 years ago, the U.S. economy was three times the size of China’s.
