Northern Ireland Economy Outpaces UK Since Brexit with 16.5 Percent Growth Since 2015
Northern Ireland has emerged as the United Kingdom's best-performing economic region since the 2016 Brexit vote, with new analysis showing the region's economy is now 16.5% larger than it was in 2015 — a remarkable performance driven in large part by a 50% surge in financial services output that stands in stark contrast to a 24% decline in the same sector across the rest of the UK, and that reflects the unique advantages of Northern Ireland's post-Brexit trading position.
Background
When the United Kingdom voted to leave the European Union in June 2016, the economic consequences for Northern Ireland were widely predicted to be severe. The region's economy was heavily dependent on cross-border trade with the Republic of Ireland, its largest trading partner, and the prospect of a hard border on the island of Ireland threatened to disrupt supply chains, deter investment, and undermine the economic normalisation that had followed the Good Friday Agreement.
The Windsor Framework, which replaced the Northern Ireland Protocol in 2023, created a unique trading arrangement for Northern Ireland — one that allows the region to remain aligned with EU single market rules for goods while remaining part of the UK customs territory. This dual access — to both the UK internal market and the EU single market — has proved to be a significant competitive advantage, particularly for businesses in sectors such as financial services, agri-food, and manufacturing that trade extensively with both Great Britain and the Republic of Ireland.
The economic data that has emerged in the years since the Windsor Framework came into effect has consistently shown Northern Ireland outperforming the UK average, and the latest analysis confirms that this outperformance has been sustained and significant.
Key Developments
The analysis, published on 22 June, shows that Northern Ireland's economy grew by 2.1% in 2025, significantly outpacing the UK's overall growth rate of 1.4%. Since 2015, the region's economy has expanded by 16.5% in real terms — a rate of growth that exceeds every other region of the United Kingdom over the same period.
The most striking finding is the performance of the financial services sector. Northern Ireland's financial services output has grown by 50% since 2015, a period during which the same sector contracted by 24% across the UK as a whole. This divergence reflects the attractiveness of Belfast as a location for financial services firms seeking access to both UK and EU markets — a proposition that has become more compelling as the post-Brexit regulatory landscape has settled. Belfast has seen significant investment from major financial institutions in recent years, with firms including Citi, Goldman Sachs, and a range of fintech companies establishing or expanding operations in the city. The availability of a highly educated workforce, competitive operating costs relative to London and Dublin, and the dual-market access provided by the Windsor Framework have all been cited as factors in those investment decisions.
Why It Matters
The economic data challenges a narrative that has been prevalent in some quarters of unionist politics — that Northern Ireland's post-Brexit trading arrangements are economically damaging and should be renegotiated or abandoned. The evidence suggests the opposite: that the Windsor Framework has created a genuine competitive advantage for Northern Ireland that is translating into real economic growth and real jobs. This is not to say that the arrangements are without political controversy — the DUP's concerns about the constitutional implications of regulatory divergence from Great Britain are genuine and legitimate — but the economic case for the current arrangements is now substantially stronger than it was when they were first introduced.
The performance of the financial services sector is particularly significant because it is a high-value, high-wage sector that creates the kind of well-paid employment that Northern Ireland needs to address its persistent productivity gap with the rest of the UK. The contrast with the UK as a whole — where financial services output has declined by 24% since 2015 — is a powerful illustration of the divergent economic trajectories that Brexit has created within the United Kingdom itself.
Local Impact
The economic growth has been felt most acutely in Belfast, where the financial services and tech sectors have been the primary drivers of job creation and investment. The Titanic Quarter and the city centre have seen significant commercial development, with new office buildings, co-working spaces, and hospitality venues reflecting the increased economic activity. However, the benefits of growth have not been evenly distributed across Northern Ireland. Rural areas in counties Fermanagh, Tyrone, and Armagh have seen less of the investment that has flowed into Belfast, and the challenge of ensuring that economic growth reaches all parts of the region remains significant. The Department for the Economy has committed to a regional economic strategy that addresses this imbalance, but progress has been slow.
What's Next
The Department for the Economy is expected to publish its annual economic assessment for Northern Ireland in July, which will provide a more detailed breakdown of the growth data and its distribution across sectors and regions. Invest Northern Ireland, the regional investment promotion agency, is preparing a new inward investment strategy that will seek to build on the region's post-Brexit competitive advantages, with a particular focus on financial services, life sciences, and advanced manufacturing. The Executive's economic advisory group will meet in September to consider the implications of the latest data for the region's long-term economic strategy.
