US dollars as a denomination!

During these few years, fears on the depreciation US dollars haven arisen. The depreciation of the dollars has mainly occured due to the staggering trade deficit. So, why the depreciation of the US dollars has created such a big commotion. This is because of the fact that many of the commodities and investment related products are denominated in US dollars. Hence, the depreciation of the dollars will result in a fall in value of the commodities (for eg. oil). Moreover, the huge spending by the US authorities will bound to result in inflation in the US. This will result in a fall in value of the US dollars as lesser things can be bought with the same amount of money. Thus, people who hold their investments in US dollars will slowly see it fall in value.
