IMF's volcano watchers see smoke from many mountaintops

The latest global stability report warns of potential fissures in the world economy from numerous places

The world's most active volcanic region is the Ring of Fire girdling the Pacific Ocean. There are 452 active volcanoes in the region and they are constantly studied to see which might be the next to erupt.

Reading the International Monetary Fund's half-yearly global financial stability review feels like a similar exercise. Looking around the world, the experts at the IMF see billowing smoke emerging from the mountaintops and hear the ominous rumble of something getting ready to blow.
