The AUD is the strongest. The CHF is the weakest
If you look at the % change from last Friday, the AUDUSD was the strongest currency in trading this week. The CHF was the weakest.
The RBA refrained from cutting rates and the action sent the AUD higher against all the major currencies in trading this week.
The CHF was little changed against the EUR - its main trading partner (down -0.11% on the week), but was hammered against the stronger AUD, NZD, USD and CAD.
The largest % decliner was the AUDCHF.
The US was the second strongest currency when compared against the other major currencies. The USD was strongest against the EUR and CHF (by 3.35% and 3.14% respectively). It only fell against the AUD.
