Trade halt due to power supply issue

Singapore Exchange has said that a three-hour trade halt in its securities market on Wednesday was due to "multiple power supply issue," local media reported on Thursday.
The bourse said that the securities and derivatives markets remained paralyzed for almost three hours from 2:18 p.m. as the hardware that provides connectivity to traders was derailed by power supply issues. The stock trading eventually resumed at 5:15 p.m. and closed at 5:45 p.m.
The market usually closes at 5 p.m.
Singapore Exchange clarified that a cyber-attack had been ruled out as a cause of the disruption.
Trading volumes in the truncated session plunged to 728 million Singapore dollars (564 million U.S. dollars) on Wednesday, compared with recent average of 1 billion Singapore dollars (775 million U.S. dollars).
