Northern Ireland's Economy and Dual Market Access a Decade After Brexit Vote

A decade on from the United Kingdom's decision to leave the European Union, the Northern Ireland economy finds itself in a unique position. Thanks to the Brexit-triggered Northern Ireland Protocol and the subsequent Windsor Framework, the region benefits from dual market access to both the EU Single Market and the UK Internal Market. This arrangement has profoundly influenced the region's trade flows, supply chains, and overall economic outlook.

The Northern Ireland Protocol was designed to prevent a hard border on the island of Ireland but effectively created a sea border with Great Britain. While introducing new barriers for goods traffic, this arrangement led to significant increases in trade between Northern Ireland and the Republic of Ireland. In the first half of 2021, goods exported from Northern Ireland to the Republic of Ireland increased by 77% year-on-year, rising from just under €1 billion to €1.77 billion. Trade in the other direction saw a 43% increase, from €1.1 billion to €1.57 billion. These figures indicate a trend of firms re-orienting their supply chains away from Great Britain towards within the island of Ireland.

The Windsor Framework aimed to address practical difficulties in implementing the Protocol, introducing 'green' and 'red' lanes for goods arriving from Great Britain into Northern Ireland. This system streamlines checks and paperwork for goods staying in Northern Ireland, while maintaining necessary scrutiny for goods destined for the EU Single Market. The government now promotes this dual market access as a unique trading advantage for Northern Irish businesses, with an Invest NI survey finding that 71% of businesses believe it is helping them grow.

Economic indicators suggest that Northern Ireland's economy has grown at a faster rate than the wider UK economy in recent years. Between 2022 and 2023, its real output grew by 1.5%, making it the second-fastest growing among the 12 UK regions. The productivity gap has narrowed, and real investment has followed, with specific commitments explicitly tied to dual access, including multi-million-pound expansions in the food and manufacturing sectors and a new EU gateway parcel depot. Service sectors, such as wholesale and retail, have also benefited from robust trade with the Republic of Ireland.

However, this unique arrangement continues to be a source of political and economic contention. Unionist parties, such as the Democratic Unionist Party (DUP), have expressed concerns that the Protocol and the Windsor Framework undermine Northern Ireland's place within the UK and oppose the application of EU laws. Despite a decade passing since the Brexit referendum, political tensions surrounding these arrangements persist, with their implications for Northern Ireland's peace process and the Good Friday Agreement remaining under close observation.

Analysts and market observers note that dual market access presents both opportunities and challenges for Northern Ireland. While some firms continue to face additional bureaucratic burdens when trading with Great Britain, others are capitalizing on frictionless access to the EU Single Market. Moving forward, Northern Ireland's adaptation to this complex trading environment and its ability to effectively leverage its unique position will be key factors shaping its economic future. Fundamental issues such as a low rate of new business formation and economic inactivity remain unresolved.
