The global economy will grow an estimated 3.5% in 2017, according to a new IMF report, as indicators continue to signal strength. Global investment, manufacturing and consumer confidence are all giving cause for optimism.

The IMFs forecasts of 3.5% growth for this year and 3.6% for 2018 are up from 3.1% in 2016.

However, the report notes that inward-looking national policies threaten the trend toward global economic integration, which has benefited the world economy.
