Oil relief supports Swiss equities as Lonza lags
The Swiss market's 0.29 percent rise followed a volatile session in equities and oil. A proposal linked to a possible early reopening of the Strait of Hormuz temporarily eased pressure on crude prices, as finanzen.ch reported on September 25, 2026.
Brent crude moved from below USD 105 back above USD 106 per barrel during the session. Bond-market selling slowed, while the report described continued nervousness across equities and oil. The report also cited a better-than-expected University of Michigan consumer sentiment reading as support for the early US-market tone.
Large-cap healthcare names weighed on the Swiss benchmark even as 14 SMI constituents rose and six fell. Roche shares closed at CHF 360.30, down 0.85 percent, according to the Swiss closing table. Novartis gained 0.70 percent, while Lonza declined 0.14 percent.
SMI and Swiss healthcare shares on September 25, 2026
The SMI closed at 13,945.71 points, up 0.29 percent, and the SPI finished at 19,771.23 points, up 0.33 percent. The SMIM gained 0.47 percent to 3,113.67 points, giving the broader Swiss mid-cap gauge the strongest reported advance among the listed Swiss benchmarks.
Roche ended at CHF 360.30, down 0.85 percent, while Lonza ended at CHF 569.20, down 0.14 percent. The Swiss market recorded a weekly SMI gain of 1.2 percent, and the closing report attributed the day's cautious advance to oil developments, bond-market stabilization and mixed large-cap performance.
US equities began the final session of the week with a positive bias, supported partly by the University of Michigan sentiment data. Swiss trading therefore ended with Lonza below both the SMI and SPI on the day, despite the positive broader-market performance.
