The State Street Global Investor Confidence Index (ICI) increased to 94.3 in June, up 21 points from the May reading of 73.
The increase was led by a jump in the North America ICI which rose 18.8 points and Asian ICI which rose 18.6 points. There was a smaller increase in Europe from 108.5 to 119.7 points.
Rajeev Bhargava, head of investor behaviour research at State Street Associates, said: “Risk appetite saw a strong rebound in June. The global ICI rose to 94.3, its highest level in almost two years, buoyed by higher sentiment across all regions.
“Unprecedented action by central banks combined with the re-opening of major economies around the globe likely drove a more optimistic tone of investors,” he said.
An ICI reading of 100 was neutral; the level at which investors were neither increasing or decreasing their long-term allocations to risky assets..
