Global inequality is growing, with half the world’s wealth now in the hands of just 1% of the population, according to a new report.

The middle classes have been squeezed at the expense of the very rich, according to research by Credit Suisse, which also finds that for the first time, there are more individuals in the middle classes in China – 109m – than the 92m in the US.

Tidjane Thiam, the chief executive of Credit Suisse, said: “Middle class wealth has grown at a slower pace than wealth at the top end. This has reversed the pre-crisis trend which saw the share of middle-class wealth remaining fairly stable over time.”
