For the first time ever, the Tokyo Stock Exchange had to halt trading for an entire day, following a hardware breakdown.
On Thursday, buying and selling were frozen for thousands of companies in the worst-ever outage for the world’s third-largest bourse.
According to the Japan Exchange Group, the operator of the TSE, the problem occurred due to a failed switch over to backups.
The exchange is replacing hardware and working to restore systems for tomorrow.
The issue apparently affected smaller stock exchanges in Nagoya, Fukuoka, and Sapporo, which share the same trading system.
The incident deals a tremendous blow to a bourse worth around 6 trillion dollars.
