Where in the world are wealth and income most unequal?

The World Inequality Report 2026 finds extreme and growing global disparities: the richest 10% now own roughly 75% of personal wealth while the bottom 50% hold only about 2%, and income is similarly skewed with the top 10% receiving 53% and the middle 40% 38% (leaving roughly 8–9% for the bottom half). Billionaires and centi‑millionaires have seen about 8% annual wealth growth since the 1990s—nearly twice the pace of the poorest half—and the ultra‑rich 0.001% now control over 6% of global wealth (up from ~4% in 1995). Inequality varies sharply by region and country — North America/Oceania average wealth is 338% of the world mean while South Africa, Latin America and parts of Asia exhibit some of the most extreme concentration (South Africa’s top 10% earn 66% of income and control ~85% of wealth), even as a few European countries show more balanced distributions — underscoring concentrated financial power amid stagnating living standards worldwide.

Analysis

The World Inequality Report 2026 documents extreme concentration: in 2025 the richest 10 percent owned roughly 75% of global personal wealth while the bottom 50% held only about 2%, and the top 10% received 53% of global pre-tax income with the bottom half earning about 8%. Billionaires and centi‑millionaires have seen annualized wealth growth of roughly 8% since the 1990s—almost twice the pace of the bottom half—and the ultra‑rich 0.001% now control over 6% of global wealth (up from ~4% in 1995), highlighting accelerating accumulation at the very top.

Inequality is highly regional: North America and Oceania average wealth is 338% of the world mean and income share is 290% of the mean, while South Africa, parts of Latin America and several emerging Asian economies show extreme concentration (South Africa’s top 10% earn 66% of income and control ~85% of wealth). Several advanced economies diverge internally—Nordics present more balanced income shares (bottom 50% ≈25%), whereas the US, UK, Australia and Japan still show top‑heavy income and minimal shares for the bottom half.

Market and policy implications include dampened mass consumer demand where income shares are compressed, elevated political and regulatory risk in high‑inequality jurisdictions, and concentrated wealth dynamics that can amplify tail risks for social and fiscal policy. Investors should track country‑level inequality metrics and any policy responses as potential drivers of asset re‑rating and volatility.

Key Decisions for Investors

• Reassess exposure to countries with extreme wealth concentration (notably South Africa and parts of Latin America and emerging Asia) and consider risk premia or hedges for heightened political and fiscal risk
• Increase allocation to liquid defensive assets and diversifiers to guard against policy‑driven volatility should redistribution or taxation debates intensify
• Monitor leading indicators—country inequality metrics, consumption growth among middle and lower income cohorts, and signs of fiscal or regulatory intervention—and adjust cyclically exposed positions if trends worsen
• Favor geographic and sector tilts toward regions with more balanced income distributions (Nordics and parts of Europe) for potential consumer‑demand resilience and lower policy tail‑risk
