SINGAPORE (Reuters) - Australian stock futures slumped early on Friday and other Asian markets looked set to follow as tensions ramped up between the U.S. and North Korea, sending investors into less risky assets such as gold, the yen and U.S. government bonds.
The MSCI World index dropped 1.1 percent overnight in its third straight day of declines and its biggest one-day slide since May 17, as U.S. President Donald Trump stepped up his rhetoric against North Korea.
Australian stock futures dropped 1.2 percent and New Zealand stocks <.NZ50> slid 1.1 percent. Japanese markets were closed for a holiday.
U.S. stock futures were marginally softer.
Overnight, Wall Street closed sharply lower after Trump, with fiery rhetoric, warned Pyongyang against attacking Guam or U.S. allies after it disclosed plans to fire missiles over Japan to land near the U.S. Pacific territory.
