Prioritisation required to rewrite unaffordable investment plans - Fraser of Allender

10th January 2026

While UK Budget consequentials and economic developments have eased day-to-day spending pressures, Shona Robison will have her work cut out to decide how to plug a £1 billion-plus gap in capital spending plans she announced just over six months ago.

This is the headline message of Scotland's Budget Report 2026-27, which is published on 9 January 2026 by the Fraser of Allander Institute at the University of Strathclyde.

Rachel Reeves' November Budget increased funding for next year by £300 million through the Barnett formula. Further improvements to tax and social security forecasts boost funding by an additional £450 million.

On current plans, the Scottish Government will use this one-off boost to offset an underlying deficit of around half a billion pounds in 2026-27 on the resource side of the ledger, continuing a years-long pattern of using exceptional items and non-recurring revenues to finance day-to-day spending.

But the gap on the capital side is too large to fill, and will require significant prioritisation. The Finance Secretary's plans in June called for £8.1 billion of spending next year, well above the £7.1 billion available even after borrowing.

Dr João Sousa, Deputy Director of the Institute, said: "The Scottish Government's job has been made easier on the resource side this year, mostly due to Barnett consequentials and some unexpected additional funding. But this boost masks the fact it will still be in underlying deficit, which means this approach cannot be relied on indefinitely.

"There is no such news on capital, and there something will have to give. We hope the long-awaited Infrastructure Investment Plan will explain to the public how projects have been prioritised - and crucially, which ones will no longer be going ahead and why."

The report includes analysis of fiscal sustainability challenges faced by the UK and Scotland. It shows that once ‘fiscal drag’ - due to threshold rising more slowly than earnings - is accounted for over the long-term, taxes are already due to go up by over 8% of GDP in 50 years’ time, or £250 billion in today’s terms. But poor productivity growth means that still isn’t enough to bring the public finances onto an even keel.

The adjustment necessary at UK level is not too severe, requiring modestly bearing down on health spending growth and slightly increasing taxes. But the effects on the Scottish Budget would be quite severe.

Prof Mairi Spowage, Director of the Institute, said: "Because so much of the funding for the Scottish Government over the long run comes from health consequentials, the UK Government bearing down on health spending growth would leave the Scottish Government short of good options to close its funding gap.

"The already large gap currently projected by Shona Robison by 2029-30 is clearly unsustainable, and makes the challenge even more daunting. The tax rises required to plug the gap seem undeliverable, largely due to Scotland having fewer very high earners, and it’s hard to see how the Scottish Government could respond without having to cut spending."

The report also includes analysis of preventative budgeting, including the importance of getting outcomes and definitions right in order to deliver the Public Sector Reform and Fiscal Sustainability Delivery Plan announced last year, and previews what to expect from the Scottish Spending Review.
