IMF head worried about world economy The head of the International Monetary Fund is expressing concern at a deterioration in the global economy. IMF Managing Director Christine Lagarde says the outlook is now more worrying as developed and big emerging nations show signs of slowing down. She spoke after the central banks of the eurozone, Britain and China all eased monetary policy indicating their concerns over the health of the world economy. In the last few months, the global outlook has been more worrying for Europe, the United States and large emerging markets," Lagarde said in a speech in Tokyo. The IMF will downgrade some of its economic forecasts later this month as economic data from major and emerging economies has deteriorated in recent months, she said. The IMF's forecasts are likely to be lower than our previous forecasts. The IMF will publish an update to its World Economic Outlook report on July 16. She welcomed growing cooperation in Europe to tackle the sovereign debt crisis but said that further fiscal cooperation was needed. In the IMF's April report, it revised upward its global growth forecast for this year to 3.5 percent from 3.3 percent in January, and to 4.1 percent for 2013 from 3.9 percent previously. Lagarde acknowledged that the two main concerns for Japan's economy were a further appreciation of the yen and risks posed by Europe's debt crisis to demand for Japanese exports.
