I just want to know what is the world’s benchmark currency today? I believe it's the dollar but I'm a little confused of what is going on with the Euro. Can the Euro become the world’s benchmark currency if it isn't yet?

Although these are major trading currencies, they are hardly the only ones.
In fact, the financial world relies on eight benchmark currencies ;)

EUR - Euro
GBP - British Pound
USD - US Dollar
CHF - Swiss Franc
CAD - Canadian Dollar
AUD - Australian Dollar
HKD - Hong Kong Dollar
JPY - Japanese Yen

(By the way, the above list is not in any order of importance.)
