United Kingdom

01Structure

The United Kingdom is the most services-weighted large economy on this site: financial services, professional services, technology and the creative industries together account for over eighty per cent of output.¹ Manufacturing survives in narrow, high-value pockets — aerospace, pharmaceuticals, specialist automotive — rather than as a broad base.

London is the organising fact of that structure. It is one of two globally dominant financial centres and remains Europe's largest, and the concentration means British output is more exposed to global financial conditions and less to the industrial cycle than any comparable economy. It also means the national figures in the panel above average a city-region with unusual productivity against regions well below the European median.

02Trade and exposure

The British trade account is the clearest statement of that structure: a goods deficit of some £221 billion set against a services surplus of about £203 billion in 2025.¹ Almost no other economy runs the two at this scale simultaneously.

Leaving the European single market and customs union in 2020 introduced border procedures on the goods half of that account, where the United Kingdom was already in deficit, while services trade — where it holds the surplus — was left largely outside the agreement and relies on the counterparty's own rules. The structural consequence is that the settlement bears on the weaker side of the account and leaves the stronger side without a framework.

03Energy and resources

North Sea production has moved the United Kingdom from energy exporter to importer within a generation, and the decline is now steep: gas output is projected to fall by about eleven per cent a year, and to be down some ninety-nine per cent by 2050 against 2025 levels.² New licensing changes that arithmetic only marginally.

What has partly replaced it is not domestic fossil fuel but interconnection and wind. Subsea cables to continental Europe now supply up to thirteen per cent of British electricity,³ and offshore wind capacity is among the largest in the world. The exposure this creates is different in kind from Germany's or Italy's: less about the price of a fuel, more about transmission, storage and the terms on which power crosses a border the country has otherwise stepped back from.

04Labour and demography

The British labour market is unusually flexible by European standards — hiring and dismissal are lighter-touch than in France or Italy — and unemployment has consequently been low through periods when output was not growing. Inactivity rather than unemployment is where the strain shows, particularly long-term sickness among working-age adults, which rose sharply after 2020 and has not reversed.

The end of free movement from the European Union in 2020 changed the composition of labour supply rather than its total; net migration from outside Europe rose to replace it. Sectors that had relied on European workers — agriculture, hospitality, haulage, parts of health and social care — adjusted through wages and through recruitment from further afield.

05Public finances

The British fiscal framework is built on rules the Office for Budget Responsibility scores at each fiscal event, with the margin against those rules — the headroom — treated as the operative number. That design makes fiscal policy directly and immediately sensitive to gilt yields in a way a constitutional limit like Germany's is not.

The mechanism is arithmetic rather than political: each quarter-point rise in gilt yields adds roughly £2.5 billion to annual debt-servicing costs,⁴ so a move in the bond market can consume the headroom and force a tax or spending decision without any change in policy. Through 2026, yields reached levels not seen since 1998 at the long end, and the headroom against the rules narrowed accordingly. The specific figures date quickly; the sensitivity does not.

06Money and prices

The Bank of England sets the rate shown in the panel above — one of the few economies on this site with genuine monetary autonomy, alongside the United States, Japan and the non-euro Europeans. Its remit is an inflation target set by the Treasury, a narrower mandate than the Federal Reserve's dual one.

Sterling's position amplifies both directions. A large financial sector and a persistent current account deficit mean the currency responds sharply to shifts in relative rates and in perceived fiscal credibility, and a depreciation feeds an import bill that includes an increasing share of the country's energy. Monetary and fiscal credibility are therefore coupled here more tightly than in an economy that borrows in a currency it shares.

07What the models expect

These are computed on this site from each series' own history, and are nobody's official projection. The bar is the range the figure lands in half the time; the dot is the central path.

Replayed from past origins on today's revised figures, the same baseline was usually off by 0.86 on consumer price inflation, 2.94 on real gdp, 0.27 on unemployment rate, 0.32 on central bank policy rate.
