Global economic divergence is defined by a wealth K-shape driven by concentrated equity ownership and strong corporate profitability outpacing wages, particularly in the US. As AI threatens to further concentrate capital returns, rising political pressure is prompting redistributive and protectionist measures that carry long-term risks for markets.
Key Takeaways
- 1.Wealth, not income, defines the global K-shape: the top percentiles continue to gain share while the middle loses ground, whereas the bottom 50% wealth share has remained broadly stable.
- 2.Equities and corporate profit margins outperforming wages are the primary drivers of wealth concentration, particularly in the US where equity ownership is highly concentrated.
- 3.Wealth concentration skews aggregate consumption toward affluent discretionary spending, but severe recessions remain contingent on financial stress and labor market shocks hitting lower-income households.
