AUD / CHF Short. Rising US revenues sent the Australian dollar south. What difference can one short day in the currency markets make? It was only yesterday that the Australian dollar rose above 80 for the first time since February 2018. And then the sharp rise in US bond yields triggered a dramatic reversal of the US dollar. The ten-year yield rose to 1.61% on Thursday, the highest level since February 2020. The yield has since fallen to 1.47%, but the sharp move caused the US dollar to rise sharply and turn the Australian dollar’s strength between long and short.
