The quantitative easing had flooded emerging markets with cheap money, but now those funds are drying up and putting severe pressure on several emerging market currencies. The worry is the problems in countries such as Turkey, Argentina and South Africa could spread to other markets.

Investors will also digest the latest growth figures from Canada and the U.S. this week.
Economists expect Statistics Canada to report Friday that gross domestic product grew by 0.2 per cent in November amid rising manufacturing sales. That would be a slight dip from 0.3 per cent GDP growth in October.

In the U.S., it is expected that data Thursday will show fourth-quarter economic growth came in at an annualized pace of 3.2 per cent, following a 4.1 per cent rise in the previous quarter.
