The United Kingdom would remain the legal obligor for all outstanding gilts and other UK government debt issued before independence. Scotland would take on a fair and proportionate share of the outstanding debt stock, or an equivalent annual contribution, as part of a comprehensive assets-and-liabilities settlement. A population share is a common reference point used in international separations; adjustments for historic contributions, oil revenues and shared assets would form part of the talks. The outcome must be transparent and sustainable for both sides. Debt allocation is one of the most sensitive files in any independence settlement. It affects Scotland’s opening fiscal path, the interest burden on the new state’s budget and the politics of fairness on both sides of the border. Treating it as automatic or as zero is not credible. Treating it as a unilateral imposition by one side invites prolonged dispute and weakens market confidence. This framework therefore places the issue where it belongs: in negotiation, against clear reference points, inside a comprehensive balance-sheet settlement, with sustainability for both parties as a design test. The main constraints are legal (creditors’ relationship is with the UK), political (both sides will defend their interests) and fiscal (an excessive Scottish share worsens an already challenging deficit; an unrealistically low share will be resisted and may lack legitimacy). Dependence on UK agreement is high; mitigation lies in transparency of method and linkage to the wider asset-and-liability package, rather than a single-line fight. How the existing stock of UK national debt would be shared is among the most politically charged and technically consequential elements of any independence settlement. Public sector net debt for the United Kingdom stood at approximately £2,990 billion at the end of June 2026, equivalent to roughly 95 per cent of GDP. Bondholders and other creditors have lent to the United Kingdom as a single legal entity. On independence, the continuing United Kingdom would remain the legal obligor for all outstanding gilts and other central-government debt issued before the date of independence. Scotland would not spontaneously inherit a carve-out of individual instruments. Instead, as part of a comprehensive assets-and-liabilities negotiation, Scotland would take on a fair and proportionate share of the economic burden of that debt, or an equivalent annual contribution designed to achieve the same fiscal effect. This section sets out the legal starting point, the reasons a negotiated contribution is both normal and necessary, the common international reference points that would guide the talks, the possible legal and financial forms the Scottish share could take, and the implications for sustainability and market credibility. It does so without committing to a single percentage or contractual structure. The governing standards are transparency, fairness relative to population and other relevant factors, and sustainability for both the new Scottish state and the continuing United Kingdom. An outcome that meets those standards supports the credibility of the wider fiscal framework; an outcome that fails them undermines it from day one. Debt allocation cannot be isolated from the rest of the balance-sheet negotiation. Physical assets, financial reserves, public-service pension liabilities and contingent claims sit in the same package. A clean, agreed division of the whole is more important than victory on any single line. The position stated here implements the negotiation red line already set out in the framework: a fair and transparent division of assets and liabilities. --- ### **Current Position and Legal/Institutional Baseline** Under the present constitutional arrangements, the entire stock of UK central-government debt is a legal obligation of the United Kingdom. The UK Debt Management Office issues gilt-edged securities, Treasury bills and other marketable instruments on behalf of HM Treasury. Bond covenants, clearing-house arrangements, and market conventions all treat the United Kingdom as the single obligor. Scotland, as a territory within the United Kingdom, has no separate legal personality in the eyes of those creditors and no independent contractual relationship with them. Public sector net debt at the end of June 2026 stood at approximately £2,989.9 billion. That figure is the stock against which any economic allocation would be calculated. Scotland’s share of the United Kingdom's population is currently around 8 per cent. A mechanical application of that share would imply an economic burden in the order of £240 billion. However, the precise figure would depend on the valuation date, the treatment of index-linked debt, the inclusion or exclusion of particular categories of liability, and the adjustments agreed in negotiation. The interest cost associated with such a share would become a recurring claim on the independent Scottish budget. International practice provides no automatic formula that a court or third party can apply without the consent of the states concerned. The 1983 Vienna Convention on Succession of States in Respect of State Property, Archives and Debts has never entered into force and does not bind the United Kingdom. Customary international law recognises that successor states ordinarily assume a portion of the predecessor’s debt, but leaves the precise method of apportionment to agreement. The dissolution of Czechoslovakia in 1993 provides the cleanest recent European precedent of a peaceful, negotiated allocation based primarily on relative population. The more complex and contested dissolution of Yugoslavia produced an IMF-brokered key that combined population, economic contribution and territorial factors. In the Soviet case, Russia, as the continuing state, ultimately assumed the bulk of the external debt under a series of zero-option arrangements with the other republics. None of these cases is identical to a Scottish independence negotiated within the United Kingdom. Yet, all of them confirm that an orderly separation normally includes an agreed contribution by the departing entity. The legal baseline is therefore clear. Creditors look to the continuing United Kingdom. Any Scottish contribution is a matter of inter-governmental agreement, not of automatic legal succession to individual instruments. That agreement forms part of the wider independence settlement and must be presentable to markets and both publics as fair and sustainable. --- ### **Mechanism and Delivery** The mechanism for allocating the debt burden is negotiation conducted in good faith as part of the comprehensive assets-and-liabilities settlement. The process would begin immediately after a clear Yes vote. It would run in parallel with the other technical working groups on currency arrangements, nuclear basing, pensions continuity and institutional transfer. Both governments would appoint negotiating teams with access to the relevant debt-management, legal and statistical expertise. An agreed set of reference points and valuation principles would be established early so the talks could focus on quantum and structure rather than first principles. Population share would serve as the initial reference point because it is transparent, readily calculable and widely used in international practice. Adjustments would then be considered for historic net fiscal transfers, the treatment of North Sea revenues that have flowed into the UK Exchequer over decades, the division of physical and financial assets (including any share of foreign-exchange reserves and public corporations), and specific liabilities that can be clearly attributed to one part of the former United Kingdom. The final package would be tested against the sustainability of the resulting debt-service burden on both sides. An outcome that left either side with an interest bill that threatened fiscal stability would fail the design test set by this framework. The Scottish contribution could take several legal and financial forms. One possibility is Scotland explicitly assuming a defined principal amount, either by issuing new Scottish instruments to refinance a portion of the UK debt or by formally novating a slice of existing gilts (the latter being more complex and less likely). A second possibility is an annual contribution payment from the Scottish Exchequer to the continuing United Kingdom for an agreed period, calculated to reflect Scotland’s share of debt service. A hybrid arrangement combining a partial principal transfer with an ongoing contribution is also possible. The precise contractual form would matter less than the economic substance: Scotland must accept a fair burden, and the continuing United Kingdom must receive a fair contribution. Market presentation and legal drafting would follow the chosen mechanism. From the first independent Scottish budget, the resulting debt-service cost would be incorporated into the fiscal rules and the medium-term fiscal plan. Interim arrangements could be used if the parties did not reach a final agreement on the quantum by Independence Day. A provisional contribution based on the population-share reference point, subject to later adjustment once the full settlement was signed, would allow both sides to plan while protecting market confidence. The independence treaty or settlement agreement would contain the final figures, the payment schedule and any dispute-resolution mechanism. --- ### **Continuity Design** Continuity of existing legal obligations to creditors is preserved by the continuing United Kingdom remaining the sole obligor on all outstanding instruments. Bondholders experience no break in the identity of their counterparty and no change in the governing law or payment mechanics of the gilts they hold. That continuity is essential for market stability during the transition. For households and businesses in Scotland, the continuity design operates through the fiscal framework rather than through any direct change to debt instruments. Debt-service costs that Scotland assumes become a claim on the Scottish budget and are therefore subject to the same prioritisation and rules that govern all other expenditure. Existing pension and benefit payments continue without interruption; the debt allocation does not alter any individual recipient's legal entitlement. Public-service pension liabilities that form part of the wider balance-sheet negotiation would be handled under the same continuity principle: accrued rights are protected, and the funding and administration arrangements are adjusted only by agreement and with appropriate transitional safeguards. The design therefore separates the creditor relationship (which remains with the continuing UK) from the inter-governmental economic allocation (which is negotiated) and from the domestic fiscal path (which incorporates the agreed Scottish burden from day one). The allocation itself does not break any existing legal right of a bondholder, pensioner, or benefit recipient. --- ### **Constraints and Trade-offs** ### Legal constraints The continuing United Kingdom is the sole legal obligor. No Scottish legislation or unilateral declaration can alter the contractual rights of existing bondholders or extinguish the UK’s liability. Any transfer of principal or assumption of liability requires either novation (with creditor consent) or an inter-governmental contribution arrangement that leaves the original instruments untouched. International law supplies principles of equitable apportionment but does not prescribe a binding formula that can be imposed without agreement. The negotiation must therefore produce an outcome that both governments can implement under their respective domestic legal systems. ### Fiscal constraints An excessive Scottish share would worsen the already challenging opening fiscal position identified in the preceding section. It would raise the interest burden that the fiscal rules and medium-term plan must accommodate. The continuing United Kingdom would resist an unrealistically low share and could lack legitimacy in the eyes of markets and of the UK public. The trade-off is therefore between a share that is large enough to be accepted as fair and small enough to keep the independent Scottish budget sustainable. Under sterlingisation, the absence of independent monetary policy removes one potential offset, making the fiscal arithmetic more difficult. ### Operational constraints Valuing the debt stock, identifying which liabilities are national rather than territorial, and modelling the interest profile of index-linked and conventional instruments require detailed technical work. Both sides must have access to the same data and the same modelling assumptions if the talks are to proceed efficiently. Building the Scottish administrative capacity to service any annual contribution or to manage any new debt issuance must be completed within the transition timetable. Transitional service arrangements can bridge gaps, but they add complexity and residual operational risk. ### Political constraints Both governments will face domestic constituencies that regard any compromise as a concession. Scottish opinion that expects a near-zero share and UK opinion that expects a full population share or more will both be disappointed by a negotiated middle ground. Sustaining political support for the eventual package across the transition period and beyond requires explaining the method and reference points transparently in advance. An overall assets-and-liabilities package that includes tangible assets and reserves can help balance the narrative on both sides. ### Time constraints Debt allocation is one of several complex files that must be resolved, or at least provisionally resolved, within the 18–24 month transition window. Prolonged deadlock would leave a hole in the opening fiscal plan and would unsettle markets. Early agreement on method and reference points, followed by intensive technical work on quantum, is therefore required. Contingency planning must assume a non-trivial Scottish burden even while the final number remains under discussion. --- ### **Consistency with the Wider Framework** Debt allocation implements the negotiation red line on a fair and transparent division of assets and liabilities. The resulting debt-service cost feeds directly into the opening fiscal position, the medium-term fiscal plan and the design of the legislated fiscal rules. Rating agencies and investors will examine it when forming a view on Scottish creditworthiness and borrowing costs. The treatment of financial reserves and foreign-exchange assets sits on the other side of the same balance-sheet negotiation. It interacts with the reserve buffer required under the sterlingisation regime. Public-service pension liabilities may form part of the same comprehensive package and must be handled consistently with the continuity principle that protects accrued rights. The long-term nuclear basing agreement at Faslane affects the defence component of the inherited spending total. It preserves a source of high-value employment and tax revenue that supports the fiscal path. The Common Travel Area-style arrangement for the free movement of people protects labour-market continuity and therefore the income-tax base that must service the debt burden. Day-one continuity of the Scottish Parliament, Government and existing institutions supplies the legislative and administrative capacity to enact the fiscal rules and to make the agreed contribution payments. The non-EU stance removes one potential source of short-term fiscal and regulatory disruption. In each case, the debt allocation shapes the arithmetic that the rest of the framework must manage; it does not alter the continuity-first and credibility-first design of that framework. --- ### **Hardest Critiques and Direct Responses** ### Feasibility A negotiated allocation is feasible within the transition timetable if both sides prioritise the file, agree early on reference points, and treat it as part of a comprehensive package rather than as a standalone confrontation. It is not feasible as a unilateral Scottish declaration of a near-zero share that the continuing United Kingdom and the markets reject. International practice shows that orderly separations produce agreed contributions; the absence of an automatic formula does not make agreement impossible; it makes negotiation necessary. The feasibility test is therefore political will and technical preparation, not the existence of a pre-cooked number. ### Cost and fiscal burden Scotland’s share becomes a claim on the independent budget through debt service or contribution payments. That cost sits inside the opening fiscal position and the medium-term plan. It is one reason prioritisation, efficiency and binding fiscal rules are required from day one. The burden is real; the question is whether it is sized fairly and managed deliberately or discovered under market pressure after an unresolved dispute. An excessively large share would tighten the fiscal constraint; an unrealistically small share would lack legitimacy and could produce higher risk premia, raising borrowing costs by another route. ### Dependence on agreement Dependence on UK agreement is high. Without a settlement, Scotland still faces the political and market expectation that an orderly separation includes a contribution. Prolonged dispute raises uncertainty premia and complicates the first independent budgets. Mitigation includes early agreement on method and reference points, transparent communication of the range under discussion, conservative fiscal planning across a plausible band of outcomes, and prioritising unilateral institution-building that does not depend on the final debt number. Contingency arrangements can keep the fiscal framework operational while negotiation continues. ### Transition risk Uncertainty about the final share can delay the publication of credible budgets and can unsettle markets during the sensitive early period. Mitigation includes early agreement on the method and principal reference points, using interim provisional contributions if needed, and communicating transparently rather than staying silent. Linking the debt file to the wider assets-and-liabilities package reduces the risk that deadlock on one number derails the entire settlement. ### Alternatives (status quo and previous proposals) The proposition that Scotland takes on no debt share is unlikely to be accepted by the continuing United Kingdom or regarded as legitimate by markets and international opinion; it would poison the wider settlement and is rejected as a negotiating position for this framework. The proposition that Scotland automatically inherits a fixed percentage without negotiation ignores the need for a comprehensive package and for adjustments that both sides can defend; it is rejected in favour of negotiation against clear reference points. Prolonged non-agreement with no planning for any debt-service cost leaves a hole in the fiscal framework and is likewise rejected; planning must assume a non-trivial Scottish burden even while the exact figure is negotiated. --- ### **Political and public credibility** The claim most likely to be called unrealistic is that Scotland can secure a “fair” share. At the same time, the continuing United Kingdom holds the stronger legal position as sole obligor to bondholders. The precise answer is that fairness is defined through negotiation using population share as a common international reference point, adjusted for assets, resource revenues and sustainability; that the UK’s legal position with creditors does not erase the political and economic case for a successor contribution; and that transparency of the overall balance-sheet deal matters more than victory on a single percentage. From the opposite direction, the claim that a population share is an unfair burden, given historical arguments about resources, is answered by the same method: negotiation is where those arguments are tested and balanced, not pre-empted by unilateral arithmetic. This framework does not pre-commit to a single number; it pre-commits to process, reference points and the dual test of fairness and sustainability. --- ### **Position Summarised** The UK's existing national debt remains a legal obligation of the continuing United Kingdom. Scotland would take on a fair and proportionate share of the economic burden, or an equivalent annual contribution, through negotiation as part of a comprehensive assets-and-liabilities settlement. Population share provides a common international reference point; historic contributions, resource revenues and the division of assets would also be relevant. The outcome must be transparent and sustainable for both sides. Fairness and sustainability matter more than any single formula. A clean, agreed allocation supports fiscal credibility and market confidence; a prolonged dispute damages both. Planning assumes a non-trivial Scottish burden while negotiation proceeds. The resulting debt-service cost is incorporated into the opening fiscal position, the fiscal rules and the medium-term plan from the first independent budget. --- ### **Conclusion** Who pays for the inherited UK debt stock is settled by negotiation, not by denial and not by unilateral arithmetic. The continuing United Kingdom remains the legal obligor to gilt-holders. Scotland would accept a fair and proportionate share, or equivalent contribution, within a comprehensive assets-and-liabilities deal, using population share as a standard reference point and adjusting for assets, resources, and sustainability. That approach matches international practice for orderly separations, serves market credibility and implements the fairness red line already set out in this framework. The exact number will be contested; the method need not be. Transparency, sustainability and linkage to the wider balance sheet are the tests. The following sections turn the resulting debt-service burden into the language markets, and voters will use next: the determination of credit rating and borrowing costs, the design of the legislated fiscal rules that keep the path back to sustainability believable, and the independent fiscal institution that scrutinises compliance. --- ### **Series Footer** This analysis forms part of People’s Future Scotland: The Independence Debate, a non-party framework examining the practical design of independence.
