The Swiss franc pared losses against the US dollar on Tuesday after USD/CHF failed to hold above 0.8100. A partial dollar pullback followed speculation over a ceasefire proposal involving Iran, though the move was limited as fears of a broader conflict continued to support safe-haven demand. The US struck targets in Iran for a tenth straight day, while Tehran retaliated against US assets in Gulf countries. Reports of attacks on vessels seeking to transit the Strait of Hormuz, alongside Tehran-backed Houthis declaring a blockade of Saudi Arabian shipping in the Red Sea, kept oil prices near six-week highs.

Diplomatic efforts continued, with Qatar and Pakistan working towards another ceasefire, and Iranian authorities saying on Monday they had received a proposal for a further 10-day pause. In Switzerland, the Swiss Federal Customs Administration reported June’s trade surplus eased to CHF 5,224 million from an upwardly revised CHF 5,989 million in May. In the US, attention turns to Friday’s preliminary S&P Global PMI, and the dollar retained a moderately bullish bias on expectations higher energy prices could pressure the Federal Reserve to raise rates in September.

USD/CHF Strategies And Implied Volatility

We recommend that derivative traders buy short-term USD/CHF call options near the 0.8100 level, as this area remains a major psychological floor. Although the pair has struggled to break higher, the shallow pullbacks suggest strong underlying demand for the greenback. Historically, when USD/CHF dips to these multi-year lows, implied volatility rises, making long straddle strategies highly profitable if a sudden breakout occurs.

Oil Price Risks, Energy Inflation, And Rate Hike Outlook

With Brent crude oil testing six-week highs near $85 a barrel due to the Red Sea shipping blockades, we advise trading bull call spreads on oil futures. The constant threat of US-Iran escalation could easily push energy prices back toward the $95 resistance level last seen in late 2023. This strategy allows us to capture the upside from energy inflation while limiting risk if a 10-day ceasefire is suddenly agreed upon.

We should also watch the upcoming US PMI data on Friday, which will heavily influence September interest rate expectations. Currently, interest rate swaps price in a rising probability of a Federal Reserve rate hike to combat energy-driven inflation. Since the Swiss trade surplus narrowed to CHF 5,224 million, the Swiss Franc lacks the strong fundamental backing to sustain its gains against a hawkish US Dollar.
