For much of the post-war period, free trade agreements were judged by simple metrics. How many tariffs were abolished? How much trade increased? How many containers crossed borders? Trade was principally about moving goods more efficiently across the world. As I explained on my BBC News interview, it goes much bigger than that in the modern era.
Today's most valuable companies produce relatively few physical goods. Microsoft exports software. DeepMind exports algorithms. OpenAI exports intelligence. Nvidia's greatest asset is not silicon but intellectual property. The value lies increasingly in ideas rather than objects.
Modern trade agreements devote growing attention to digital regulation, intellectual property, data governance, research collaboration, investment protection and the mobility of skilled professionals. These subjects would have occupied only a marginal place in trade negotiations fifty years ago. Today they are often more economically significant than tariffs themselves.
The UK–India relationship illustrates precisely this shift.
The agreement undoubtedly reduces barriers on goods ranging from whisky to textiles. Yet its long-term significance lies elsewhere. It strengthens investment, facilitates professional mobility, encourages technology partnerships and creates an environment within which innovation ecosystems can flourish. Britain gains greater access to one of the world's largest pools of entrepreneurial and technological talent. India gains greater access to global capital, trusted legal institutions and international markets. Both benefit not simply from exchanging products, but from integrating capabilities.
This evolution also explains why trust has become central to trade policy.
Globalisation once assumed that economic efficiency alone should determine supply chains. Recent experience has challenged that assumption. The pandemic exposed vulnerabilities in global logistics. Geopolitical tensions demonstrated that strategic dependence carries economic costs. Artificial intelligence has raised questions about data sovereignty, cybersecurity and technological resilience.
As a consequence, countries increasingly prefer to trade deeply with partners they trust politically as well as commercially. Economic relationships now rest upon shared legal standards, regulatory compatibility and confidence that critical technologies will not become instruments of geopolitical coercion.
Trade has therefore become an extension of national security.
Critics argue that this trend represents the retreat of genuine free trade. They fear that economics is becoming subordinated to politics. There is merit in that concern. The more governments distinguish between trusted and untrusted partners, the further the world moves from the universal liberal trading order envisaged after 1945.
Yet complete separation between economics and geopolitics has always been something of an illusion. The East India Company was simultaneously a commercial enterprise and an instrument of state power. The difference today is not that trade has become political. It is that political trust has become an explicit condition of economic integration.
This has profound implications for Britain.
The country's greatest comparative advantage is no longer low-cost manufacturing. It is the combination of world-class universities, sophisticated financial markets, respected legal institutions and global connectivity. These are precisely the assets that attract ambitious entrepreneurs seeking to build international businesses.
The future of trade will therefore be determined less by the movement of containers than by the movement of ideas and people.
In the twentieth century, countries competed to manufacture products more cheaply.
In the twenty-first, they compete to become the place where the world's brightest minds choose to build them.
