The Australian dollar weakened a bit today as the report showed that the retail sales in Australia declined in the last quarter of the previous year.

The unexpected decline of the US unemployment rate last week bolstered the South Korean won by improving the outlook for the exports of the Asian nation.

The Australian dollar rallied against all other most-traded currencies this week without any noticeable opposition as the economic recovery boosted commodity prices and caused Australia’s central bank to revise its growth forecast upwardly.
