USD to CHF in August 2026: high, low, average
Updated September 26, 2026
One US dollar was worth 0.80755 Swiss francs on average in August 2026. The dollar began the month at 0.80798 and finished at 0.80855, a change of only 0.07%. Behind that flat result was a month with a clear dip: a high of 0.81264 on August 13 and a low of 0.79899 a week later, on August 20.
The August 20 drop
Most of August was calm, with the rate moving in small steps just above 0.80. On August 20 the dollar fell 1.38% against the franc in a single session, to 0.79899. That one day accounts for most of the month's range of 1.71% between the low and the high. The dollar then recovered over the final week and ended the month close to where it started.
Across the month the rate rose on 13 fixings and fell on 8. A month with more up days than down days that still ends flat usually means one or two large down days, and this August was exactly that.

The figures are cross rates: the ECB publishes euro reference rates, and the dollar to franc rate is derived from EUR/USD and EUR/CHF of the same day.
How August compares
- July 2026: average 0.81067. August was 0.38% lower, so the franc was slightly stronger.
- August 2025: average 0.80702. August 2026 was 0.07% higher, practically the same level.
In other words, a dollar bought almost exactly as many francs in August 2026 as it had a year earlier.
What this means for travellers and cross-border workers
For people paid in dollars and spending in Switzerland, a higher USD/CHF rate is better. In August 2026 the best reference day was August 13, at 0.81264 francs per dollar. The least favourable was August 20.
For people earning francs and paying in dollars, the logic reverses: on August 20 each franc bought the most dollars. At the monthly average one franc was worth 1.2383 dollars.
The Swiss franc often moves sharply on single days, as it did on August 20. If a payment can wait, checking the rate over a few days before converting can make a visible difference. When comparing, use the reference rate as the neutral benchmark and treat any gap with your bank's rate as a fee.
Choosing a rate for records
For bookkeeping, the monthly average of 0.80755 is the simplest option if your policy allows it. If you need the rate of a specific transaction, pick it from the daily table above or from the daily rates page, because in a month with a one-day drop the average and the transaction-day rate can differ.
