The government wrongly says an EU re set will give us more economic growth. They think they can get non tariff barriers to trade in goods eased to promote more activity. Let’s look at the basic arithmetic.
In 2024 the UK imported 1.7 times as much as it exported in goods to the EU, running a large deficit. If they could get barriers eased so that they could expand trade by 10% both ways, our goods exports would go up by £17.7 bn and our goods imports by ££30 bn . GDP figures add in exports as that is activity and value added created in the UK. Imports subtract where we close UK production to buy from activity abroad. So with a symmetric 10% increase in goods trade GDP would be reduced . The UK would need to find ways of creating or keeping barriers against imports to help growth from the EU trade route.
To keep GDP constant the UK would need to increase its goods exports by 70% more than its imports, given the much lower base of exports in our trade. So if imports rose 5% we would need to grow exports by 8.5% just to stand still.
In practice it is difficult to see how the UK will get non tariff barriers or border bureaucracy so reduced that it will achieve a measurable increase in trade. A few easings for meat and dairy helps a tiny sector of our exports. Meanwhile our past leading exports to the EU include diesel and petrol cars, about to be banned in UK, oil and gas, put into accelerated rundown by Mr Miliband, and refined oil products where we have just shut one third of our refineries.
Exporting more goods to the EU is not going to be a source of more growth for the economy on current government policies.
If the relatively small admin costs of exports to the EU are such a big worry the government could give every exporting company a subsidy to cover them. The cost would be less than 10 % of the money the UK is likely to give the EU each year for this alleged benefit.
