FX.co ★ Swiss Franc Weakens Amid Diverging Rate Outlooks

The Swiss franc weakened to 0.83 per USD, its lowest level in a week, pressured by rising short positions amid expectations of further monetary tightening in other major economies. In contrast to other central banks, the Swiss National Bank left its key rate unchanged at 0% at its September meeting. Vice Chairman Martin stated that no adjustment was currently necessary, citing low and stable inflation, limited spillover risks, and an economy that is functioning "very well." Policymakers have also toned down their rhetoric on potential currency interventions. Swiss borrowing costs have remained the lowest in the world for over a year, enhancing the franc’s appeal as a funding currency for carry trades as interest-rate differentials with other major economies widen. As traders increase their short positions, selling pressure on franc-funded loans weighs on the currency. However, safe-haven demand, driven by concerns over debt sustainability in neighboring European economies, continues to offer some support and poses a risk to carry trades.
