Stock markets slip amid signs global economy is weakening

US markets dropped sharply following falls from Europe and Asia as the IMF trimmed its economic forecasts for 2019

Stock markets across the world fell Tuesday amid further signs that the global economy is weakening.

US markets dropped sharply following falls across Europe and Asia as the International Monetary Fund (IMF) trimmed its economic forecasts for 2019 and 2020 and pointed to risks including trade tensions and rising interest rates. China's government said its economy grew in 2018 at the slowest pace since 1990.
