(NEW YORK) -- More than ever the U.S. is part of the global economy, with millions of American workers depending on jobs linked to imports and exports.
But a new warning that the world's economy has weakened further could mean a slowdown for global trade and the biggest threat out there to American jobs.
In its latest update, the International Monetary Fund forecasts global growth of 3.3 percent this year -- down from an estimate of nearly 4 percent just three months ago. Slower growth is also forecast for 2013.
"Risks for a serious global slowdown are alarmingly high," says the IMF's World Economic Outlook.
The report comes one day after a forecast of a deepening slowdown in China, the world's second largest economy. India -- another engine of growth -- is also facing a serious slowdown.
