SIX Swiss Exchange has been forced to delay the start of trading by three hours because of a "technical problem".
Trading of equities and ETFs will commence at 12.00pm CET, derivatives at 12.15pm, and international bonds at 12.30pm.
Separately, insurer Aviva was yesterday hit by a five hour outage at its UK Web site, according to tech news site the Register, clogging up call centre lines.
