William Hague says
today that by 2015 Britain will no longer be in the top 10 economies. Presumably he is basing it on
this.
But is it realistic? The IMF forecasts out to 2014, and by that date it has (using current dollars) this order - US, China, Japan, Germany, France, UK, putting us in sixth position - then Italy, Brazil, Russia, India, Canada. The exchange rate assumption then is 1.61 sterling to the dollar, which is clearly about 6% higher than the current rate. The euro assumption is 1.364, so about 1% higher than the current rate. Thus on current exchange rates the IMF's numbers would be 5% lower for the UK. But our GDP is forecast then to be $2,919bn, and Italy's $2,355bn. Today it takes a 1.08 exchange rate to make Italy's GDP higher than ours; the current rate is about 1.10, so the IMF is also forecasting stronger UK growth than in Italy. History suggests this is likely (recent history at least) but if it isn't and the exchange rate v euro doesn't improve, the UK could fall to seventh. [see
here for more on this comparision]
To fall to eight it must go below Brazil, and on IMF figures this would require 2 reals to the pound, up from 2.7 at present. To fall below India will need 57 rupees, from the current 68, which seems possible. Canada would require 1.08, from 1.53 at present.
So it seems likely that the UK could lose some places, on the other hand if the euro weakens it will gain two (Italy and France). It seems unlikely it will fall to 11th however.
Using PPP exchange rates makes it seem even less likely, even thoug on this measure the IMF has the UK at 7th by 2014. This is because it remains 60% higher than Canada, and and 30% higher than Italy according to IMF estimates - a large gap to make up (of course PPP estimates can be revised, but this seems unlikely between these countries). In general I think Hague is wrong.
ps [note this data is to 2014 - to 2015 makes it a little less comfortable for the UK]
pps Also Hague says: "Under a Conservative government, the Foreign Office budget would not depend on fluctuations in the exchange rate (as it does under a system introduced in 2007)". How strange to ignore the signals sent by a flexible exchange rate.
