The Swiss stock exchange SIX paused trading on Wednesday at 11:30 CET due to a data dissemination issue impacting all products. Trading resumed after the problem was resolved.
SIX Halts Trading Due to Data Issue
As a result of issues with the dissemination of data, the Swiss stock exchange SIX paused trading on Wednesday at approximately 11:30 CET (09:30 GMT). The exchange stated that trade would restart at approximately the same time.
According to Reuters, at approximately 10:00 Central European Time (CET), SIX discontinued trading in Switzerland across all products, including exchange-traded funds, bonds, and equity securities.
Trading Resumes After Data Issue Fixed
Later on, however, it was reported that the data issue had been resolved and that trading in stocks and exchange-traded funds (ETFs) would resume at approximately 11:30 CET, with bond trading following at approximately 12:00 CET.
Despite the fact that the Spanish stock exchange, which is operated by SIX, also experienced data issues, trading continued as usual.
The market is functioning smoothly, according to a representative for the Spanish stock exchange, who stated, "We are analyzing some incidents in the dissemination of data." However, business as usual prevails in the market.
Previous Outage in June 2023
Nestle, Roche, and UBS are just few of the corporations that have their headquarters on the Swiss stock exchange, shares CNA. An outage that lasted approximately three hours occurred in June of 2023.
SIX announced on its website that many trades, including those in bonds, exchange-traded funds (ETFs), and structured products, were deemed to be "mistrades" and were subsequently annulled in Switzerland.
When the LSEG workspace was updated at 8:50 GMT, the prices for Spain's IBEX index were being updated.
