The mood of investors has been jittery this week after tariff announcements from the U.S. and China. U.S. President Donald Trump on Monday warned of the possible imposition of tariffs on $200 billion of Chinese imports. This followed his move to raise levies on $50 billion of Chinese goods and equal retaliation by Beijing.
"Market participants are still carefully waiting for signs of a turnaround in the U.S.-China tariff measures before they are implemented on July 6," said Will Leung, head of investment strategy for Hong Kong and greater China wealth management at Standard Chartered Bank. "I don't think Trump is eager for a reversal at the moment, as he is eyeing the November midterm elections and will continue bargaining with China. Hong Kong and global equities are being sacrificed in the meanwhile."
