Swiss Franc edges higher as US-Iran tensions, higher Swiss yields sustain support

USD/CHF trades around 0.8120 at the time of writing on Wednesday, down a modest 0.09% on the day, but remains supported by a strong risk-off environment that favors the US Dollar (USD). Investors continue to seek the Greenback as tensions in the Middle East escalate, reducing hopes for a diplomatic de-escalation.

Hostilities between the United States (US) and Iran have now entered their eleventh consecutive day. US President Donald Trump dismissed the prospect of immediate negotiations with Tehran following the exchange of military strikes and threatened to target Picaxe Mountain, a site believed to house nuclear facilities. In response, Tehran warned that any attack on these facilities would expand the conflict across the region.

Tensions have also spread to global shipping routes. Houthi rebels announced a blockade of the Bab el-Mandeb Strait, prompting three Saudi Oil tankers to turn back in the Red Sea. The situation has renewed concerns about disruptions to global energy supplies and continues to underpin demand for safe-haven assets.

In Switzerland, the 10-year government bond yield is hovering around 0.45%, close to its highest level in two months. Rising energy costs driven by geopolitical tensions are prompting markets to reassess the outlook for inflation and monetary policy. Despite these developments, the Swiss National Bank (SNB) kept its policy rate unchanged at 0% at its latest meeting, maintaining that inflation is expected to remain broadly stable over the medium term.

USD/CHF support builds as SNB tolerates weaker Swiss Franc and safe-haven bid fades

Analysts at ING argue that “USD/CHF rather than USD/JPY could become an increasingly popular vehicle for these summer months,” noting that the SNB “is not going to surprise with $70bn of FX intervention (as the BoJ did in April/May).” In their view, “the SNB probably welcomes this weaker Swiss Franc,” with the central bank “look[ing] to be one of the last central banks to hike” at a time when “higher energy prices and higher rates in general deliver wider interest rate differentials against Swiss rates.” ING says it has “been discussing a higher USD/CHF over recent weeks,” adding that “if energy prices have another leg higher, USD/CHF could deliver some powerful follow-through on a break of 0.8150/70 resistance,” and that “high oil and high equity prices look set to keep USD/JPY and USD/CHF supported.”

Strategists at Rabobank observe that “CHF net shorts have fallen for a third week,” as “CHF’s Iran war-driven safe-haven rally has faded, while SNB intervention warnings have helped limit speculative demand.” Against this backdrop, Rabobank expects “EUR/CHF consolidating around 0.92 over three months and USD/CHF near 0.81 in H2,” suggesting a period of range trading rather than renewed aggressive safe-haven inflows into the Franc.
