Investing
Rather than viewing these developments as separate stories, markets are increasingly treating them as interconnected. AI is driving unprecedented capital expenditure, governments are borrowing heavily to fund infrastructure and defence, geopolitical tensions are reshaping trade patterns, and shifts in US policy are influencing everything from inflation expectations to currency markets.
Taken together, these forces are creating a more complex investment backdrop. While uncertainty remains elevated, market participants are focusing less on individual headlines and more on how these broader trends interact and influence one another.
A resilient but more uneven market environment
The global economy has once again proved more adaptable than many expected. Businesses have adjusted supply chains and technology investment continues to support economic activity. Growth remains positive, albeit more moderate and uneven than in previous cycles.
The result is an environment where markets are increasingly being driven by regional and sector-specific factors rather than a single global narrative. While the US continues to benefit from strong investment and productivity gains, other regions are also attracting attention as domestic reforms, demographic trends and policy initiatives begin to influence growth prospects.
Leadership within equity markets is also starting to broaden. For much of the past two years, returns have been concentrated among a small number of technology-related companies. More recently, investors have begun looking beyond these market leaders, exploring opportunities in industries and regions that may benefit from a wider range of economic and structural trends.
At the same time, inflation remains an important consideration. Although inflationary pressures have eased from their peaks, they remain higher than the levels that prevailed during much of the decade following the global financial crisis. This has implications for interest rates (see the recent rate rise from the US Federal Reserve), government borrowing costs and the performance of different asset classes.
The challenge remains distinguishing short-term market volatility from longer-term economic change. Sharp market movements often attract the most attention, but the underlying trends shaping corporate earnings, investment decisions and economic growth tend to unfold over many years.
Artificial Intelligence: Expanding beyond technology
Artificial Intelligence (AI) is no longer simply a technology-sector story. Increasingly, it is becoming an infrastructure, energy and investment story with implications that extend far beyond software companies and chip manufacturers.
The scale of investment remains substantial. Technology firms continue to spend heavily on data centres, cloud infrastructure and AI development, creating demand that spreads across multiple sectors. The growing energy requirements of AI infrastructure are also drawing attention to power generation, electricity networks and energy storage solutions.
This broadening impact is one of the most significant developments in markets today. While technology companies remain central to AI innovation, investors are increasingly examining which industries may benefit indirectly from the adoption of AI technologies.
At the same time, expectations remain high. Market leadership continues to be concentrated among a relatively small group of companies, and valuations in some areas reflect considerable optimism about future growth.
Recent market experience has highlighted an important distinction between successful businesses and successful investments. Strong growth alone is not always enough to drive share prices higher if expectations are already elevated. As a result, debate has shifted from whether AI will transform the economy to which companies and sectors are most likely to capture the value it creates.
The US Dollar: Still dominant, but facing questions
The US Dollar remains at the centre of the global financial system. Its position as the world’s primary reserve currency, combined with deep capital markets and continued global demand for US assets, continues to underpin its influence.
However, questions are increasingly being asked about the factors supporting the dollar’s long-term strength. Large fiscal deficits, rising government debt and higher interest costs have renewed discussion about the sustainability of US public finances.
Monetary policy adds another layer of complexity. Although slower economic growth would typically point towards lower interest rates, inflationary pressures have recently prompted the Federal Reserve to raise rates. The balance between softer growth and persistent inflation will be an important factor in determining the dollar’s future direction.
What remains clear is that currency markets continue to play an important role in shaping investment returns, trade flows and global capital allocation. As economic conditions diverge across regions, currency movements may become a more significant influence on markets than many investors have experienced in recent years.
Trump, trade and policy uncertainty
President Trump’s return to the White House introduced a renewed focus on trade policy, tariffs and domestic economic priorities.
Supporters argue that tariffs and industrial policies can strengthen domestic manufacturing, encourage investment and reduce reliance on foreign supply chains. Critics contend that such measures can increase costs, reduce efficiency and contribute to inflationary pressures.
The debate itself is not new, but its implications have become increasingly important for markets. Trade policy now has the potential to influence corporate investment decisions, pricing strategies, supply-chain management and economic growth across multiple regions.
For businesses and investors, uncertainty may be as significant as the policies themselves. Sudden changes in trade arrangements can affect sectors and industries differently, creating both opportunities and challenges depending on how economic relationships evolve.
This has reinforced the importance of looking beyond individual policy announcements and focusing instead on the broader economic consequences they may create over time.
Global debt and the return of capital costs
Record levels of global debt have become a defining feature of the current economic landscape. Governments continue to borrow heavily to support infrastructure, defence spending, energy transition projects and economic growth initiatives.
The more important question, however, is not simply how much debt exists, but how much it costs to service. As older debt is refinanced at higher interest rates, borrowing costs are becoming a more significant consideration for governments around the world.
This does not necessarily point to an imminent crisis. Stronger nominal growth and higher inflation have helped many economies manage rising debt burdens. Corporate and household balance sheets also generally appear healthier than during previous periods of financial stress.
Nevertheless, higher borrowing costs can influence government spending choices, fiscal policy and economic growth. They may also affect how investors assess risk and value different assets.
Perhaps the most notable change is that the price of capital matters again. After years of exceptionally low interest rates, financing costs have re-emerged as a key economic and market variable.
Conflict and geopolitics: No longer a side story
Geopolitical developments are increasingly becoming a structural market consideration rather than a temporary source of disruption.
The conflicts in Ukraine and the Middle East continue to illustrate how geopolitical events can influence energy prices, trade routes, defence spending and investor sentiment. Even when markets quickly recover from individual shocks, the longer-term implications can persist.
At the same time, governments and businesses are reassessing supply chains, national security priorities and access to critical resources and technologies. In many cases, resilience and security are becoming more important considerations alongside efficiency and cost.
This shift is influencing investment decisions across multiple sectors, including energy, infrastructure, defence, manufacturing and technology.
While markets have historically demonstrated a remarkable ability to adapt to geopolitical uncertainty, the broader trend appears to be one of increasing fragmentation rather than greater integration. That trend is likely to remain an important influence on economic and market outcomes for years to come.
Understanding the bigger picture
Many of the most important market themes of 2026 are closely connected. AI investment is increasing demand for energy, infrastructure and capital. Governments are balancing higher borrowing needs with defence and economic priorities. Trade policy, inflation and interest rates continue to influence currencies, growth expectations and asset valuations. Geopolitical developments can amplify many of these effects.
The challenge is that these forces rarely operate in isolation. Progress in one area can create pressures in another, making the investment landscape more complex than headline narratives often suggest.
Yet complexity does not eliminate opportunity. AI continues to stimulate investment well beyond the technology sector. Higher interest rates can change the economics of borrowing and lending. Structural reforms in several regions are creating new areas of market interest, while evolving trade relationships are reshaping global supply chains and investment flows.
Volatility is likely to remain a feature of markets, but the more important story may be the interaction between these powerful long-term trends. Understanding how they influence one another is likely to be as important as understanding any individual theme in isolation.
The value of investments can fall, as well as rise, and you might not get back the original amount invested. Exchange rate changes affect the value of investments.
