Why sovereignty is reshaping investing in a fragmented world

A year ago, I described a ‘shadow world’ in which predictability had broken down, where geopolitics had become more personalised, more volatile and harder to interpret. 

That diagnosis still holds. But looking back over the past 12 months — and reflecting on discussions at this year’s Aberdeen Global Investment Forum [1] — I believe we were only describing the symptoms.

The deeper shift now underway is more structural. Nations are no longer just reacting to instability. They are seeking to regain control — over their economies, their technologies and their security. For investors, this marks a profound change.

From stability to fragmentation

To understand how we arrived here, it is worth briefly revisiting the three phases that shaped the modern world.

Between 1989 and 2004, we lived in a period of remarkable confidence. Liberal democracy expanded rapidly. Globalisation accelerated. A rules-based international order, underpinned by the United States, created a framework that appeared both stable and broadly benevolent.

For investors, the direction of travel was clear. Markets operated within a predictable system.

That confidence began to erode in the decade that followed. China’s economic rise challenged the assumption that openness would lead to political convergence. The global financial crisis exposed deep inequalities. New technologies, particularly social media, reshaped how information spread and how politics functioned.

By 2014, the system had begun to fracture.

In the past decade, that fracture has widened into something more fundamental. Populist leaders have reshaped domestic politics. International relationships have become more transactional. The assumptions that once underpinned global cooperation have weakened.

That is what I described as the ‘shadow world’.

From unpredictability to sovereignty

Over the past year, however, something else has become clearer. The defining characteristic of today’s world is no longer simply unpredictability, it is sovereignty.

Countries are asking more urgent questions about dependence:

These questions are shaping policy decisions in real time.

The United States, which once anchored the global order, has increasingly adopted a more transactional approach using tariffs, security relationships and economic leverage in ways that can shift quickly. Allies and partners, from Europe to the Gulf to Asia, are now reassessing long-standing dependencies.

This is a reordering of the global system around competing centres of power.

What we misunderstood

One of the most important lessons from the past year is how often we get these shifts wrong.

Many of us underestimated the resilience of populist politics. We assumed that unconventional behaviour would carry a heavier political cost. In reality, voters have often proved more tolerant than expected.

We also struggled to impose coherence where there may be none. Policies (particularly in areas like trade) have sometimes reflected multiple, conflicting objectives rather than a single, consistent strategy.

For investors, this matters. It highlights the limitations of traditional models. And it reinforces the need for humility, for recognising that even careful analysis can fail to capture the complexity of the world we are now operating in.

Geopolitics moves to the centre

In this environment, geopolitics is no longer a peripheral consideration. Economic indicators and market data remain essential, but they are no longer sufficient on their own.

Investors must also understand how political decisions are made, where power resides and how strategic competition shapes industries.

Scenario planning becomes critical. In a world where events can cascade rapidly from a single political decision to global market consequences, investors need to prepare for multiple outcomes, including those that once seemed unlikely. 

This may mean modelling outcomes where supply chains fragment, technology access is restricted or alliances suddenly change.  

Sovereignty and the new battlegrounds

The shift toward sovereignty is most visible in a handful of critical areas. What were once sectors are now arenas of strategic competition. 

Energy remains fundamental. The transition to cleaner energy sources is not only about sustainability, but also about independence and resilience.

Technology, particularly artificial intelligence, is emerging as an equally important domain. While AI continues to drive powerful investment themes, it also raises questions about control over data, over infrastructure and over economic advantage.

More broadly, control of key assets such as energy systems, data centres, semiconductor-supply chains, represents a new form of geopolitical leverage.

These developments are shaping capital flows, policy priorities and long-term opportunity.

Reasons for optimism

Despite the more challenging geopolitical backdrop, there are reasons for cautious optimism.

First, systems still push back. Institutions, legal frameworks and voters themselves continue to exert influence. Political trends are not always linear and outcomes are not predetermined.

Second, innovation remains powerful. Advances in energy and technology are creating new opportunities even in a more fragmented world.

Finally, the focus on sovereignty may, over time, drive greater resilience. Countries that invest in infrastructure, diversify supply chains and strengthen domestic capabilities could emerge more robust.

Final thoughts

We are moving beyond a ‘shadow world’ defined by uncertainty into one characterised by competing sovereignties.

This does not mean the world is becoming simpler. If anything, it is becoming more complex. But it does mean that the dynamics driving markets are becoming clearer.

For investors, the implications are significant. Geopolitics must sit at the heart of analysis. Scenario planning must become more rigorous. Conviction must be grounded not in certainty, but in an understanding of how the system itself is evolving.

The rules are no longer fixed but new patterns are emerging. Those who can recognise them early, and adapt, will be better placed to navigate what comes next.
