Postfinance resolves banking glitch as Sandoz and Galderma join SMI

Postfinance experienced a technical malfunction in its online banking system on September 19, 2026. For approximately two hours, the digital interface incorrectly displayed account balances as 0 francs, causing significant concern among users. A spokesperson for Postfinance later clarified that the incident was a pure display error and confirmed that all funds remained secure and physically present in the accounts.

In separate financial news, the Swiss Market Index (SMI) underwent a restructuring. Pharmaceutical and healthcare companies Sandoz and Galderma have joined the Swiss blue-chip index, replacing Swisscom and Kühne+Nagel. This shift increases the healthcare sector's weight within the SMI to approximately 40 percent, following the existing presence of major players like Roche and Novartis. The new additions saw a strong market debut, with Galderma shares rising 2.6 percent and Sandoz increasing by approximately 1 percent.
