Access to single market no substitute for EU membership, thinktank warns in latest report on Brexit

Gaining access to the single market will still leave Britain substantially worse off than if it continued as a full member of the EU, a study today warns.

The research adds that that new trade deals would not compensate for the damage to UK trade from leaving the single market.

The Institute for Fiscal Studies (IFS) claims that membership of the single market could be worth a potential 4% of extra gross domestic product (GDP) to the UK compared with World Trade Organisation (WTO) membership alone.

This could add almost two year’s worth of growth to Britain’s economy, according to the report.

‘Virtually meaningless’

The thinktank said the boost to the country’s trade, public finances, growth and living standards far outweigh the costs of single market membership across Europe.

Its report, which was funded by the Economic and Social Research Council, added that just having access rather than membership of the single market was “virtually meaningless”.

The IFS sent out some stark warnings over the impact of Brexit ahead of the EU referendum, saying it would lead to two more years of austerity.

Its earlier reports on Brexit said lower growth and extra borrowing of Brexit would knock a £20bn to £40bn hole in the Government’s finances by 2020.

‘Big choices’

In its latest study, the IFS warned Britain now faces some “very big choices” in negotiations with the EU.

Ian Mitchell, research associate at the IFS and an author of the report, said: “There is all the difference in the world between ‘access to’ and ‘membership of’ the single market.

“Membership is likely to offer significant economic benefits particularly for trade in services. But outside the EU, single market membership also comes at the cost of accepting future regulations designed in the EU without UK input.”

The report claims that while leaving the EU will free the UK from an estimated £8bn a year of budget contributions, the loss of trade from Brexit could hit tax receipts by a larger amount.

It found new trade deals would be unlikely to make up for lost EU trade, which accounts for 44% of British exports and 39% of service exports.

Official figures from the Office for National Statistics on Tuesday showed the UK exported £12bn worth of goods and services to the EU in June, an increase of £500m compared with May.

‘Any country has access’

The IFS said single market membership also removes trade barriers, such as licensing and other regulatory constraints, to supplying goods or services.

The IFS said: “Any country in the WTO – from Afghanistan to Zimbabwe – has ‘access’ to the EU as an export destination.

“Single Market ‘membership’ by contrast involves elimination of barriers to trade in a way that no existing trade deal, customs union or free trade area achieves.”

Single market membership is likewise vital to financial services firms, allowing so-called passporting rights to trade with a country in the European Economic Area.

The IFS added: “Membership may come at the cost of continuing to contribute to the EU Budget and accepting future regulations designed in the EU.

“Those costs are salient and the benefits of membership are diffuse – but the financial benefits are real and, at the moment at least, likely to outweigh the financial costs.”
