On the 19th (local time), some services such as news on the London Stock Exchange (LSE) in the UK were suspended shortly after opening, but it was confirmed that there was no impact on the domestic securities trading system.
According to the Financial Supervisory Service and the financial investment industry on the 19th, global stock and exchange-traded fund (ETF) trading through domestic securities firms' Mobile Trading Service (MTS) and Home Trading Service (HTS) are being executed normally.
A Financial Supervisory Service official stated, "Currently, there have been no separate reports from securities firms." A representative from a major securities firm also said, "The error appears to be limited to the news service operated by the London Exchange, and the trading system itself is operating without issues," adding, "Some securities firms are connected to the LSE system-wise, and if there were any impact, it would have appeared immediately."
However, in the case of swap transactions, it is known that one foreign securities firm, A Securities, which uses Microsoft (MS) cloud services, is experiencing operational difficulties, resulting in orders not being executed normally.
According to local reports, this disruption is understood to be due to the impact of a failure in MS's cloud service. The LSE stated on its homepage, "A third-party global technology issue has occurred in the RNS news service, causing news not to be posted," and added, "The technical team is working to restore the service, and this does not affect LSE's stock trading or other services."
