Swiss Franc Weakens, Dollar Firms Ahead of PCE Inflation Data

USD/CHF edged higher during Wednesday's Asian session, trading around 0.80333 after recovering from a slight earlier dip. Markets turned cautious ahead of key US inflation data, with the dollar finding buying support, serving as the main driver behind the pair's stabilization and rebound.

**PCE Data Becomes Key Short-Term Catalyst**

Markets are closely watching the upcoming US Personal Consumption Expenditures (PCE) data, a core gauge used by the Federal Reserve to assess inflationary pressures. According to market expectations, the US core PCE year-over-year rate for July is projected to rise 3.3%, unchanged from June; the headline PCE year-over-year rate is expected to ease slightly to around 3.6% from June's 3.7%. If actual data comes in higher than expected, it would reinforce inflation stickiness, thereby strengthening the case for further Fed rate hikes, potentially driving a synchronized rebound in the dollar and US Treasury yields. Conversely, if the data falls below 3.3%, Fed rate hike expectations could cool, pressuring the dollar lower.

**Swiss Franc Lacks Independent Drivers**

On the Swiss franc front, there are no strong independent catalysts recently, with its moves largely dictated by the overall dollar strength. Earlier, the Swiss National Bank hinted at possibly reinstating negative interest rates, adding some pressure on the franc. Ahead of the US PCE release, market sentiment remains cautious, and the short-term direction of USD/CHF will heavily depend on how the inflation data reshapes Fed policy expectations.

**Technical Picture and Market Sentiment**

On the charts, USD/CHF is stabilizing around 0.80333, indicating some support below. If PCE data surprises to the upside, the pair could test higher resistance levels; if the data is benign, it may give back recent gains. Analysts note that recent US July CPI and PPI readings showed no clear acceleration in inflation, which has already partially reduced market bets on near-term rate hikes. Therefore, whether this PCE data can break that benign expectation will be key in determining the dollar's short-term trajectory.
