The Swiss franc weakened past 0.81 per USD, remaining near a three-week low, on a widening interest rate differential with the United States and selling pressure from new carry trades. A hawkish sentiment of the Bank of Japan and yen-buying interventions by Washington and Tokyo reduced the appeal of the yen for carry trades, leading traders to shift positions to other safe-haven currencies, such as the swiss franc. The swing pressures the currency as traders sell their franc loans for higher-yielding assets in other currencies. Contrasting with other central banks, the Swiss National Bank is expected to leave its key policy rate unchanged at 0% through year-end, the lowest among major economies. Providing an offsetting pressure, global oil prices breached the $100 mark as tensions in the Middle East escalate further, raising safe-haven demand.
