Brexit and the impact for Ireland

02nd April, 2015

The UK and Irish economies have always had a close relationship. The possibility of Britain leaving the EU would have consequences for Irish trade, but not as much as in the past.

Free trade between Ireland and the UK has always been important to the Irish economy. In 1928, the interdependence of the two economies was acknowledged by the creation of a new currency, the Irish pound. Its exchange rate with sterling was fixed at parity. The significance of the economic relationship was one of the reasons that Ireland and the UK joined the European Economic Community (‘EEC’). That relationship lasted until 1979 when the UK decided to opt out of the European Exchange Rate Mechanism (‘ERM’) which forced a break in the link between the two currencies.


UK/EU relations

From the outset, Ireland was a more enthusiastic member of the EU. The relationship between the UK and its European partners has always been more strained. It did take two attempts for Ireland to ratify the Nice Treaty and the Lisbon Treaty, but most European referenda in Ireland have passed with large majorities. Ireland joined the ERM at its foundation in 1979 and in 1999 there was an overwhelming majority in favour of replacing the Irish pound with the euro.

The UK also joined the ERM, but its membership did not last long and it was quickly followed by a dispute with the newly elected Conservative government, led by Prime Minister Margaret Thatcher, on the UK’s contribution to the European budget. In 1984, after much disagreement, a significant rebate to the UK was agreed. There has never been any real enthusiasm in the UK for membership of the single currency.

More recently, UK/EU relations have been further strained as the Eurozone crisis has prompted moves towards banking, fiscal and economic union which may require deeper political integration. Most UK political parties oppose any further transfer of sovereignty to Europe. The lack of enthusiasm towards Europe has been best illustrated by the significant increase in support for the UK Independence Party (‘UKIP’) which wants Britain to leave the EU.

To placate his increasingly vociferous backbenchers, Prime Minister David Cameron announced a new European strategy in January 2013. He proposed a more flexible, adaptable and open EU and promised that, if re-elected, the Conservative Party would hold an in/out referendum on EU membership in 2017.



In order to answer this we must first ask how likely is it that a referendum will be held. And if one is, what is the likely outcome? A referendum is only guaranteed if the Conservatives achieve an overall majority in the general election on 7th May. Current polls suggest this is unlikely.

But even if a referendum takes place, recent opinion polls suggest that around 45% would vote to remain in the EU with 35% against. This is almost an exact reversal of the polls taken when the referendum was first mooted in 2013. Moreover, if the referendum takes place after a renegotiation of Britain’s relationship with Europe and there is a positive recommendation from Prime Minister David Cameron, the polls indicate the majority in favour of remaining in Europe jumps to around 55%.

‘Open Europe’ is an independent think tank that analyses European affairs. It recently created a ‘Brexit Barometer’ which calculates the probability of the UK remaining in or exiting the EU in the next parliament. The barometer takes account of the probability of a referendum taking place and the likely result of the referendum. Currently the barometer estimates the probability of the UK staying in at 83% and the probability of leaving at just 17%.

What would the impact of a Brexit be?

Although the probability of a British exit from the EU seems low, it is worth exploring what the consequences would be if it were to happen. They depend on the new relationship between the UK and the EU after the exit.




Links between the two economies are still very strong

However, if the new relationship between the UK and the EU changed dramatically and trade barriers and tariffs were erected, then the consequences for the Irish economy could be significant. The dependence of the Irish economy on the UK has fallen in recent decades, but it remains an important trading partner.

When Ireland and the UK joined the EEC in 1973, over 50% of Irish exports went to the UK. That figure has dropped to just over 16% today. Although over 40% of Irish exports go to the remainder of the EU, the UK remains our single most important export market in Europe. Some 20% of Irish exports now go to the US.

The true importance of the UK economy as a trading partner is understated by these figures. A significant portion of the growth in exports to the US and mainland Europe reflect the operations of the multinational sector where the real value added is diluted by transfer pricing. In contrast, a much higher proportion of exports to the UK are from indigenous Irish industries where the real economic value added is considerably higher. Perhaps a better indicator of the economic relationship between the two economies is the fact that more than one-third of Irish imports come from the UK.
