5 reasons to worry about the world economy Group member Tina Grace Winnie Tiffany Tuya Turuu

1. Japan falters A surprise slowdown in the third quarter tipped the world's third largest economy into recession.

2. Eurozone malaise There's little reason for cheer in Europe. While Germany narrowly avoided a recession in the third quarter, the latest number show the $13 trillion eurozone economy is stuck in first gear.

3. Commodity crunch  Oil price have tumbled 24% this year to about $75 a barrel as jitters about the brittle European recovery and geopolitical fears deter buyers.  Meanwhile prices for iron ore -- a key ingredient in steel -- have plunged 40% as China takes its foot off the gas. For years the economic powerhouse has been slowing and last month the country reported its worst quarter of growth in more than five years.

4. Emerging markets  China's slowdown spells trouble for a number of commodity-rich emerging markets, not least Brazil. Growth there has collapsed and the IMF sees expansion of just 0.3% this year.  Turkey is another emerging country failing to fire, as domestic political struggles and war on its border weigh on confidence.

5.Geopolitical risks The war in Syria and Iraq is just one of the wild cards. Amid fresh clashes in Ukraine, tensions between Russia and the West are rising again. European officials were meeting Monday to consider adding more individuals to their list of sanctions.
