A POPULAR idea is floating around certain circles: that you do not need a deep
trade deal with the EU in order to trade with them in a significant way. For
instance, Guido Fawkes, a blog, points out that each year China trades with the
EU to the value of half a trillion dollars. But China is not in the single
market and so does not have to accept annoying rules and regulations. Japan
trades a lot with the EU, but is not in the single market and does not have to
accept free movement of labour (it has net migration close to zero, in fact).
This has implications for post-Brexit Britain, of course. The implication seems
to be that Britain need not be in the single market in order to trade lots with
the EU.
But take a closer look at the figures, and that rosy conclusion is thrown into
doubt. It is true that America, China and Japan trade lots with the EU (our
chart looks just at goods trade, which is easier to measure). But these
countries are much, much bigger than Britain is. So, proportional to the size
of their economies, they do a tiny amount of trade with the EU in comparison to
Britain. By our measure, EU trade relative to GDP is at least five times as
important to Britain as it is to the three other economies we look at. The
single market, in a word, matters.
