(Reuters) – If the world becoming less economically integrated, someone is going to have to explain why growth around the world is so remarkably consistent and tightly correlated.

It isn’t just that all 45 OECD countries are growing together for the first time since 2007, but that the level of growth around the world is as similar as its been in a long time. Growth levels among the Group of 10 wealthy nations are as tightly clustered – meaning rates of growth are similar – since at least 1991, and among 21 countries, large European Union countries’ growth figures are as tightly packed as they’ve been since at least 1997.
