Also weighing on sentiment, British Prime Minister Theresa May abruptly postponed a parliamentary vote on her Brexit agreement on Monday, a move that hit risk assets globally and sent the pound GBP= spiralling down to $1.2505. data from major economies including China and Japan have also fanned worries about corporate earnings and factory output, with the Sino-U.S. trade battle clouding the outlook for world growth.
Among emerging markets, investors will focus on India where the central bank governor shockingly resigned on Monday. Patel's resignation for 'personal reasons' goes to reinforce the widened rift between the central bank and the government," said Robert Carnell, Asia-Pac chief economist for ING. "The news is clearly a significant negative for the markets."
