The 2026 football World Cup will be the largest in history. For the first time, 48 nations will compete, up from 32, and it will be co‑hosted across three countries: the United States, Canada and Mexico. This expanded format creates more qualifying places, particularly for regions that have historically been under‑represented and introduces additional routes into the tournament.
Global capital markets have followed a similar path. The MSCI Emerging Markets equity index now covers 24 countries, up from 10 at launch, and its share of global market capitalisation has more than doubled since 2000. The bond market has expanded too. Local-currency emerging market (EM) debt markets have grown significantly over the past decade and EM government borrowing in dollars has risen sharply, with new issuers joining the field alongside familiar names.
A 48-team World Cup gives more nations a seat at the table — but not on equal terms. The same is true in markets.
1. Past strength is not a forward-looking indicator
Italy are four-time World Cup winners but have now missed three consecutive tournaments. Their decline was not sudden — it reflected years of underinvestment in infrastructure, youth development and institutional renewal, masked by a reputation that took longer to fade than the foundations beneath it.
Economies and companies follow similar patterns. A strong sovereign credit rating can coexist with slow-moving fiscal deterioration for years before markets reprice it. A company with a dominant market position can see its competitive advantages erode long before it shows up in headline earnings. Markets have repeatedly punished investors who mistook historical dominance for inevitability.
2. A wider field raises the cost of complacency
With more teams and more qualifying pathways, competition arrives from more directions. The global investable universe has expanded — more economies, more issuers, more markets to access. But wider participation has not produced more uniform outcomes. The range of outcomes across economies remains wide, and at company level, the gap between winners and laggards within the same sector or region has grown too.
In that environment, broad exposure carries a hidden cost. In equities, index-level allocations increasingly mean holding large positions in companies and markets whose earnings growth is under pressure, alongside a smaller set that is genuinely well-positioned. In fixed income, owning the whole field means lending to sovereigns and corporates whose credit paths can be very different.
3. Diversification means understanding how economies and companies are wired, not where they sit on a map
A portfolio can span multiple regions and still be concentrated in the same underlying risks — sensitivity to dollar funding conditions, exposure to a single commodity cycle, or dependence on global manufacturing demand. The same applies at the company level: two banks in different countries may look similar on a balance sheet but face entirely different regulatory, currency and credit environments.
The more useful lens is economic and business profile: what drives growth, how policy is managed, where external vulnerabilities lie, and how an economy or company is connected to global capital.
A manufacturing-led economy in Southeast Asia may have more in common with Mexico than with a commodity exporter next door. A well-run company in a frontier market may offer better risk-adjusted income than a lower-yielding name in a slower-growth developed economy. Diversification built on these foundations is more durable than diversification built on a map.
