Renewed speculation about a September US interest rate hike stems from Fed Vice Chairman Stanley Fischer's statements saying the US job market is currently close to full strength. Moreover, one week earlier, New York Fed President William Dudley said a September rate hike is a possibility. Monetary tightening in the world's largest economy causes funds to flow from the more risky, yet higher-yielding emerging market assets back to the USA.

Investors will be eager to search for new clues about the looming US interest rate in the content of a speech that will be delivered by Fed Chair Janet Yellen in Jackson Hole (Wyoming) where global policy makers will meet later this week for an annual meeting.

Crude oil plunged 1.7 percent on Monday after having climbed almost USD $10 per barrel since the start of August. Previously, oil climbed on the back of speculation that members of the Organization of the Petroleum Exporting Countries (OPEC) are to agree on a production freeze deal with non-OPEC producers led by Russia. Today, however, oil fell as Iraq signaled it is to boost crude oil exports.
