On the central bank front, no major speeches are set to take place by the Federal Reserve on Tuesday. However, investors will be looking to the 2017 Economic Policy Symposium on "Fostering a Dynamic Global Economy" at Jackson Hole due later on this week.

At the meeting, Fed Chair Janet Yellen and European Central Bank President Mario Draghi are both set to speak, with investors watching the event closely for any indications when it comes to monetary policy outlook.

Meanwhile, politics will remain on the minds of investors, after President Donald Trump committed the U.S. to an open-ended conflict in Afghanistan, reversing course from what Trump had pledged during his election campaign, Reuters reported.
