The US-UK “special relationship” is an ideological narcotic for Britain’s ruling classes in the post-colonial era. King Charles’s state visit – featuring a White House banquet and address to Congress – perfectly embodies this narcotic function in a turbulent post-Brexit Britain and a volatile and conflict-ridden second Trump administration waging a war on Iran. The Royal visit formally celebrates 250 years since the 1776 US declaration of independence from British colonial rule (ironically framing separation as enduring kinship) while signalling continuity of elite ties under Trump. Royal symbolism adds cultural prestige, masking policy and power asymmetries (over trade, military spending, and divergences on the Iran war). For Britain’s ruling elites, it reinforces the illusion of equal partnership; for the US, it affirms exceptionalist leadership with a reliable ally. Such rituals help manage hegemony’s turbulence, building consent even as material power leans heavily westward and even that is increasingly in doubt and fast-losing popular and international credibility.Illustration: Pariplab Chakraborty.This particular visit occurs in the midst of a cesspool of scandals that embroils the Royal family, President Trump and his circles, and the British political establishment. The ghost of Jeffrey Epstein haunts the corridors of Anglo-American elite power, leading to the sacking of Peter Mandelson, UK ambassador to the US, laws in America forcing release of millions of files from the Epstein estate, and placing dynamite beneath the seemingly invincible Donald Trump. Mass protests are expected to stalk King Charles as he tours the US; rather than cementing the special relationship, it may well more starkly expose its rotten core.Who benefits?In addition, there are material inequities in the benefits that accrue from the special relationship, reinforcing domestic class and regional inequalities, explored below. The “special relationship” persists as a hegemonic delusion: a narcotic sustaining British elite self-image after empire, perfectly compatible with American exceptionalist domination. Historical episodes – from Suez to Iraq – show elites on both sides investing in the ideology because it delivers networked influence, even as it perpetuates hierarchy at home and in Anglo-American relations. The Royal visit ritually renews the dose. True power analysis requires piercing the consensual veil to examine whose interests the order truly serves.Placing a precise monetary value in pounds on the economic benefits of the special relationship to Britain as a whole is inherently challenging. No official comprehensive cost-benefit analysis isolates the “special” aspects (intelligence sharing, military interoperability, elite networks) from baseline bilateral ties that any close partners might enjoy. Trade, investment, and returns occur in a market context, but the relationship enhances elite stability, market access, technology transfer, and risk mitigation in ways that are hard to quantify.Using recent official data (primarily from the UK Office for National Statistics (ONS), governmental and parliamentary reports), we can estimate the scale of direct financial flows and then discuss qualitative multipliers and distribution. The UK-US trade relationship is huge – but its economic impact is often overstatedThe UK-US trade relationship is often described as “special”, and in sheer scale that is true. In the year to the third quarter of 2025, total trade in goods and services between the two countries reached about £329.5 billion, making it one of the largest bilateral trade relationships in the world. The US is the UK’s largest single trading partner, accounting for roughly 17.5% of total UK trade, ahead of any individual EU country.What matters most, however, is the structure of that trade. UK exports to the US totalled around £200 billion, driven largely by financial, professional and business services, and the creative industries. Services exports alone were worth about £137 billion, while goods exports were closer to £60 billion.Imports from the US were lower, at about £126-127 billion, leaving the UK with a trade surplus of over £70 billion on the official UK measure. Despite this scale, economists have long estimated that even a comprehensive UK–US free trade agreement would generate only modest GDP gains of around 0.07–0.16%, reflecting already low tariffs and hard-to-remove regulatory barriers. The UK–US relationship, then, is economically important – but it is not a shortcut to rapid growth.Special Investment Relationship Talk of the UK-US “special relationship” tends to focus on trade, but investment is at least as important – and more revealing about who benefits. Two-way foreign direct investment between the UK and the US is frequently estimated at around £1.2 trillion in total stock, making it one of the deepest bilateral investment relationships in the global economy. The US is the largest single source of inward foreign direct investment into the UK, accounting for roughly 30% of the UK’s total inward FDI stock, while the UK is also a major investor in the US, with around £530 billion invested, representing approximately 28–29% of UK outward FDI. These investment ties generate large income flows. UK companies earn substantial profits from their US operations, making outward FDI income an important contributor to the UK balance of payments.At the same time, US inward investment supports high-value activity in the UK across sectors such as technology, pharmaceuticals, finance, automotive manufacturing and war industries.Foreign-owned firms, including a large concentration of US multinationals, account for a significant share of UK business turnover, reaching around 38% in some non-financial sectors, underlining the structural importance of inward investment to the British economy. Dividend payments and reinvested earnings associated with overseas investment are large but volatile. In recent years, UK companies’ global outward investment profits have been reported at over £100 billion annually, with the US a major component of that total.Despite these returns, the UK’s overall net international investment position remains negative. Even so, investment exposure to the US continues to offer British firms and investors access to large, innovative markets that often deliver higher returns than domestic alternatives, helping to diversify risk. Long-standing intelligence, military and security ties also matter. These relationships are widely seen as reducing geopolitical risk and supporting higher confidence in cross-border investment flows, even if the economic value is difficult to quantify directly. Military production cooperation produces indirect economic benefits. Programmes such as the F-35 fighter collaboration embed UK firms in US-led supply chains and R&D ecosystems, generating industrial returns that would be costly to replicate through purely national capabilities. Taken together, UK–US economic integration involves hundreds of billions of pounds in trade and investment activity each year, supporting jobs, corporate earnings and technology spillovers, yet no credible analysis assigns a single monetary value to a “special relationship premium”. Unequal BenefitsWhat is much clearer is how unevenly the gains from the UK-US investment relationship are distributed. The primary beneficiaries are large corporations, financial institutions, defence firms and highly skilled professionals, groups that are disproportionately connected to transatlantic markets and capital flows. This reflects the wider structure of the UK economy, in which foreign-owned firms generate almost 30% of total gross value added in the non-financial business economy, despite accounting for a very small share of enterprises by number, underscoring how value creation is concentrated among large, often multinational firms.These benefits are also regionally concentrated, particularly in London and the South East, which dominate high-income employment, finance, corporate headquarters activity and access to global capital markets. The UK is one of the most regionally unequal advanced economies, with London pulling away over several decades as finance and business services expanded, while many other regions experienced deindustrialisation and weaker productivity growth.Defence-related gains follow a similar pattern. Major firms involved in UK–US interoperability and joint programmes – such as BAE Systems and Rolls-Royce – are embedded in well-resourced industrial clusters that combine skilled labour, government procurement and export access, delivering high returns to firms and shareholders while anchoring employment in specific regions rather than across society as a whole.Special for some, unequal for mostWider benefits do exist. US-linked investment supports hundreds of thousands of jobs directly and indirectly, contributes to tax revenues, and generates innovation spillovers through research, supply-chain integration and skills development.But these gains are more diffuse and fragile, and they sit alongside stark underlying inequalities. Wealth and income in the UK are already highly concentrated, with the top 1% holding more wealth than the bottom half of the population combined, and regional wealth levels in the South East far exceeding those in much of the rest of the country.Viewed through a critical political-economy lens, the UK-US investment relationship underpins an elite-centred economic order that is routinely framed as serving the national interest, but is experienced very differently across British society—delivering outsized rewards to capital owners and highly skilled elites while offering more limited, uneven and uncertain benefits to the wider population.The ideology of the “special relationship” legitimises this hierarchy: elites gain networked influence, prestige, and material returns, framing subordination as partnership. The masses receive diffuse benefits (jobs, security narrative) that sustain consent, but without proportional share of surplus. Regional/sectoral concentrations mean some areas gain more (London/finance versus post-industrial regions), and recent deals highlight vulnerabilities in export-dependent manufacturing.Overall, the relationship delivers substantial economic value (hundreds of billions in activity, with net positives in trade/investment returns), but its “narcotic” function for the establishment lies in how it sustains elite access and post-colonial self-image, while distribution tilts toward the top – direct corporate/elite gains, indirect (and more precarious) benefits for workers and the public via multipliers and stability.Class interests drive special relationshipBritain has a ruling-class stratum whose material interests, ideological outlook, and institutional power are deeply intertwined with the United States – its former colony that surpassed it as global hegemon after 1945. This is best understood as a transnationalised elite fraction within a core capitalist state that has accepted a subordinate position within a US-led hegemonic order. The “special relationship” serves as the ideological glue – the “narcotic” – that makes this subordination palatable and profitable for them, even as raw power asymmetries have widened. And in a globally volatile environment, the unpredictability, recklessness, and sheer corruption of the current US administration threatens to drag Britain into another illegal war in West Asia.Inderjeet Parmar is professor of international politics and associate dean of research in the School of Policy and Global Affairs at City St George’s, University of London.
