2031 CEBR Predictions
USA and China will each have about $35 trillion. China is now expected to pass the USA in about 2029.
However, any significant 25% surge in China's currency could put China into the number one position by about 2022.
India should be in third place by itself with about $10-11 trillion. India will be one third of the US or China economies but double Japan.
Japan, Germany and the UK should have about $5 trillion each.
South Korea, Brazil and France should be in the $3.5 trillion range.
Canada, Indonesia, Mexico, Italy and Russia should be in the $2.4 to 2.7 trillion range.
South Korea and India should move up. European countries other than UK are expected to weaken.
Most forecasters expect Brazil to have a hard time for a number of years because of bad governance.
