FED IN FOCUS: The U.S. central bank's policymaking committee is holding a two-day meeting. There's not likely to be any market-moving news when it announces its decision, which comes after Asian markets close. Most analysts expect officials to keep rates unchanged. The Fed has already raised rates three times since December and market watchers don't expect another hike until later this year or in 2018.
ANALYST VIEW: "The market expects a near-zero probability of a rate hike this time, but the central bank's policy outlook will be closely watched by market participants nonetheless," said Margaret Yang, analyst at CMC Markets in Singapore.
