The Global Balance Sheet in 2026: Record Wealth, Real Risk

Global wealth just hit an all-time high but a closer look at where that growth is coming from tells a more complicated story.

New research from the McKinsey Global Institute (MGI), published in July 2026, puts the world's total assets at nearly $1.8 quadrillion in 2025, up from $1.7 quadrillion the year before. Household wealth alone reached a record $570 trillion. On the surface, that's unambiguously good news. Dig into how MGI arrives at that number, though, and the picture gets more complicated with real implications for how business leaders, investors, and advisors should be thinking about the next few years.

Why Track a "Balance Sheet" for the Entire World?

Companies don't just look at how much they earned this year, they also track what they own and owe, because a business can look healthy on its income statement while quietly becoming fragile on its balance sheet. Since 2021, MGI has applied that same logic at a global scale, estimating assets, liabilities, and net wealth across roughly two dozen major economies that together account for about 70 percent of global GDP.

The underlying premise is straightforward: over the long run, asset values should track the real economy that supports them. When valuations start growing much faster than output and income, that gap tends to close eventually ideally through faster productivity, but sometimes through inflation or a sharper market correction instead.

The latest edition of this research finds that gap widening in several major economies.

The Number Worth Sitting With: Just 20% of New Wealth Was "Real"

Here's the headline finding: of the roughly $40 trillion added to global household wealth in 2025, only about a fifth came from genuinely new investment new buildings, machinery, infrastructure, and intellectual property. The rest came overwhelmingly from asset valuations climbing faster than inflation.

That's a meaningful shift. Between 2000 and 2024, real investment accounted for closer to 30 percent of wealth growth on average. In 2025, valuation-driven gains took over even further, with equities alone responsible for well over half of new household wealth worldwide a sharp reversal from two decades in which real estate was usually the biggest contributor.

Wealth built on genuinely more productive assets tends to be durable. Wealth that grows mainly because valuations are stretching further from the assets underneath them is more exposed if conditions shift whether through inflation eroding real returns or a market pullback.

Two Economies Pulling in Opposite Directions

MGI's report covers dozens of countries, but its overall findings are dominated by the world's two largest economies and they're telling very different stories.

The United States is where the valuation story is most visible. US equity values have climbed to roughly 2.4 times corporate net assets, a ratio that sits closer to 1.0 in most other countries, while corporate profits as a share of GDP have roughly doubled since 2000. A large share of the recent gains trace back to a handful of AI-linked technology companies. That's a bet that US corporate earnings keep outgrowing the broader economy for years to come plausible, but not guaranteed, especially with government debt sitting near 120 percent of GDP.

China is working through the opposite problem. Corporate debt has climbed to roughly 80 percent of the value of corporate real assets, well above the 40–50 percent range typical elsewhere, even as close to 30 percent of Chinese firms reported losses in 2025 and producer prices kept falling. Real estate, long the backbone of household wealth in China, keeps declining. Government spending and corporate investment have kept overall growth going, but the country is still working through what MGI calls a partial balance-sheet reset.

Everywhere else, the picture looks calmer. Household debt and real estate values across most of Europe and other advanced economies have actually settled closer to their 25-year historical norms, aided in part by post-pandemic inflation.

Four Paths Forward

MGI frames what comes next around four possible scenarios — a useful mental model for any business trying to plan through uncertainty:

1. Productivity acceleration — the best case. Real income growth catches up to justify today's asset values. Rare, and not guaranteed even in the US, but the only path that protects wealth without inflicting pain elsewhere.

2. Sustained inflation — elevated prices quietly erode the real value of both debt and wealth over time, at a cost to savers.

3. Secular stagnation — asset values stay high, but growth stays weak and leverage keeps building. MGI places Europe roughly here today.

4. Balance sheet reset — a sharper correction: falling asset values, deleveraging, and a stretch of slower growth, echoing what China is navigating now and what Japan went through in the 1990s.

No major economy is locked into a single path. The report points to specific factors that could shift each one toward the better outcome: deeper deficit reduction in the US, stronger business investment in Europe, and a bigger pivot toward domestic consumption in China.

What This Means If You're Running a Business

A few takeaways stand out, wherever your business is based:

• Don't confuse rising valuations with underlying strength. If a market, sector, or portfolio is appreciating mainly because multiples are expanding rather than earnings growing, that's worth knowing before treating the trend as durable.

• Watch debt quality, not just debt levels. Corporate debt has actually come down in much of the world. Where it hasn't: China being the clearest example it's worth tracking closely, particularly against the assets it's secured against.

• Plan for more than one scenario. MGI's own guidance to executives is to build balance sheets, corporate and personal, that can hold up whether the next few years bring stronger growth, higher inflation, stagnation, or a sharper correction. Flexibility in cost structure and financing tends to matter more than betting heavily on one outcome.

• India sits outside this particular dataset, but not outside its consequences. MGI's sample spans about 70 percent of global GDP across economies like the US, China, the eurozone, and Japan: it doesn't cover India specifically. Still, a US equity correction, a Chinese debt-and-property unwind, or a European slowdown would all ripple into trade, capital flows, and investor sentiment that Indian businesses feel directly, especially those with international clients or operations.

  
  

The Bottom Line

Global wealth is at a record high, but the number alone doesn't say much without asking where the growth actually came from. Right now, a large share of it is sitting in valuations rather than production not necessarily a crisis, but a trend worth watching closely over the next few years.

For businesses trying to plan through that uncertainty: where to invest, how much leverage to carry, how to prepare for genuinely different economic outcomes: that's exactly the kind of complexity worth working through with the right advisory partner.
