Scotland, Wales, Northern Ireland to Sign Deal Aimed at UK Break-Up

The first ministers of Scotland, Wales and Northern Ireland are set to meet in Cardiff on Monday to sign a joint declaration pushing for independence referendums, a move framed as the first formal step toward dissolving the United Kingdom. At an unprecedented summit in Cardiff, the three first ministers will put pen to paper on a joint declaration demanding the right to hold independence referendums.

Who is signing

John Swinney, leader of the Scottish National Party and the first minister of Scotland; Rhun ap Iorwerth, leader of the Welsh independence party Plaid Cymru and first minister of Wales; and Michelle O’Neill, leader of Sinn Féin and first minister of Northern Ireland, are all slated to meet in Cardiff, the capital of Wales.

The move was made possible by the political earthquake brought about by the May elections, a bloodbath for Labour that saw independence parties seize majorities in Northern Ireland, Scotland, and Wales for the first time.

What the declaration covers

The declaration signed by Scotland’s John Swinney, Wales’s Rhun ap Iorwerth and Northern Ireland’s Michelle O’Neill will cover four key areas, according to the report: economy, energy, Europe, and international cooperation and self-determination.

It will state that Scotland and Wales wish to enter the European Union as new members, and that Northern Ireland will enter the EU by way of unifying with the Republic of Ireland, which is already a member. Wales, according to the report, will use the agreement as a way to pressure Prime Minister Andy Burnham to hand over additional powers to the devolved Welsh government, particularly relating to tax and spending.

The Trump angle

The summit lands one day after a notable intervention from Washington. During a visit to Dublin, American President Donald Trump said he would “love to see” Northern Ireland unite with Ireland and that “it’s going to happen eventually.” The New York Times described Trump’s comments as breaking with decades of US precedent.

Trump reiterated his support for Northern Ireland breaking from the United Kingdom to unify with the Republic of Ireland, but said he won’t talk about Scotland becoming independent “yet.” “You have Northern Ireland and you have Ireland and it would seem to me that one of the naturals of all time is to put them together,” Trump told reporters during a visit to the Irish Open golf tournament.

Why traders should care

Constitutional risk in the UK has historically shown up first in sterling and gilts, and a formal push for referendums, even non-binding, can revive that premium. Watch for GBP volatility around headlines from Cardiff and any response from Westminster.

Energy and financial names with heavy UK exposure are the most direct read-throughs, given the declaration specifically calls out economy, energy and EU re-entry as pillars.

Options market and stocks to watch

A few names sit closest to the flashpoint if this story develops into an actual referendum track:

• EZGBP: currency ETPs and GBP crosses tend to move first on UK constitutional headlines. Watch for skew and IV shifts.
• BP and SHEL: North Sea exposure means Scottish independence chatter historically hits energy majors. Watch for headline-driven flow.
• BCS and LYG: UK-listed banks are the cleanest domestic proxy for constitutional risk. Watch for widening in credit and any pickup in put activity.
• EWU: the broad UK equity ETF is the simplest way to track how markets price the whole story.
