This week has been extremely volatile for the U.S. dollar as different events moved markets sentiment among traders, forcing the dollar slightly down today after it rallied from the lowest level in 2009 versus the euro yesterday.

The Brazilian real posted another negative session today as movements in the central bank led traders to speculate that further measures will be taken to halt the real’s rally, which already rose 34 percent versus the greenback this year.

The Canadian dollar had the first day of losses versus its U.S. counterpart and several other key-currencies as the price of commodities declined this Thursday after a sharp rise that started in the beginning of this week’s session.

The Australian dollar continued its yearly rally to set a new record high in 2009 after a report indicated an improved number of monthly jobs added in October, suggesting that the nation’s central bank is likely to continue its current policy of rate hikes for the next meeting.

After several days driven by risk appetite globally favoring high-yielding currencies and forcing commodities rates up, the rally was halted as China affirmed that the economic recovery is uneven, raising concerns among safeties and attracting them to the safety of the Japanese currency.

The Australian dollar, the second best performing currency in trading markets this year after the Brazilian real, climbed further as China, its main trading partner, posted positive economic figures this Wednesday, adding confidence to the already attractive Aussie.

The British pound went down versus most of the 16 main traded currencies this Wednesday after Bank of England officials affirmed that a weaker pound can boost the economic recovery in the nation, shunning traders from pound priced assets.

The U.S. dollar touched its lowest level in more than a year versus most of its main rival currencies as speculations suggest that the Federal Reserve will maintain borrowing costs in a historic record low, as the economy still urges for stimulus to provide a more solid recovery.

The Canadian currency traded at the highest level in almost a month after China posted a report indicating a sharpened growth, consequently favoring the loonie’s outlook due to Canada’s exporting economic profile, which is likely to be more favored than the U.S. in the short term of an economic recovery in global scale.

Canada is one of the main suppliers of oil to the United States, and as the barrel passed the $80 dollars mark, the Canadian currency found support to extend previous gains as investors return to purchase assets in Canada, favoring the loonie in currency markets.
