Globalization and trade

Data from the World Trade Organization show that since the end of the Second World War there has been an exponential (in the mathematical sense of the word) increase in trade between countries (red line in the chart). One striking aspect of this is the lack of sensitivity to the price of oil (blue line), which seemingly contradicts Jeff Rubin's thesis in his new book "Why Your World Is About to Get a Whole Lot Smaller: Oil and the End of Globalization". In fact there is a positive correlation (0.48) between oil prices and trade, which remains (0.43) when trade flows are lagged two years.

However, Rubin's predication is that oil will increase in price by an order of magnitude within a very few years - presumably then the current (lack of) relationship will change?

If he's right, then do we still have the infrastructure to reverse the off-shoring that has been going on steadily for the last decade or so? This is not just a question of physical assets, but skills, some of which take time to learn.
