US dollar value fluctuating

US dollar value is fluctuating a lot last 1 month and it has gradually risen by 5% and we hope it rises by another 5 % equalling Indian rupees to 45. The rise and fall in US dollar directly affects other currencies of the world. I have to deal with Omani rials and dollar decides its exact value. More the value of US dollar, more i get for Omani rials. even other world currencies like Euro, pounds, Indian rupee, etc. depend on US dollar. But past few months, i have seen Australian and Canadian dollar almost equalling US dollar. There were times when AUS and CAD $ 's where 60 % of US $ but they are almost equal. The bad US politics has surely affected US $.
