Of note, all but one of 29 economists from major houses expect the SNB to keep its policy rate unchanged throughout the year. The lone exception is Barclays, who forecasts that the Swiss central bank is to cut interest rates to -0.25% in Q2 2026 and hold that until year-end.And that means all 29 economists are expecting the SNB not to make any changes to monetary policy later this week. That is very much well expected even if the US-Iran conflict has complicated things for policymakers.In essence, a return to deflation is what the SNB wants to avoid. But amid a stronger franc currency, that will continue to weigh down price pressures in the Swiss economy. And that's one key challenge that the central bank is facing up against right now.In light of that, 14 out of 15 economists who responded to an extra question said that the SNB should step up currency interventions to address further strengthening in the franc. I would say that is to no one's surprise with EUR/CHF having already tested waters below 0.90 early last week.That rather than leaning towards unconventional monetary policy to try and solve the problems in Switzerland.Julius Baer notes that:"For the SNB, sharp Swiss franc appreciation is the most immediate concern. We continue to view foreign exchange interventions as the SNB's primary tool to counter such sharp, safe-haven-driven CHF appreciation." This article was written by Justin Low at investinglive.com.
