The New Zealand fell today, scrapping two sessions of the advance against the US dollar, as the International Monetary Fund said that the currency too overvalued.

The Canadian dollar advanced against the euro after Standard and Poor’s downgraded Greece’s credit rating, fueling concern that the nation may face default or even leave the Eurozone. The Canadian currency also rose against the US dollar and the Japanese yen.

The euro rallied today on speculation that the European Central Bank will increase its interest rates even as the threat of the sovereign-debt crisis persists. The optimism quickly waned, though, and the currency experienced a sharp drop.

The Australian dollar rose today as the number of jobs available in Australia grew and on speculation that China will increase its imports.

This week was really bad for the euro as an impressive rally of the previous weeks quickly turned into a sharp slide, reducing optimism of euro bulls and making them question sustainability of the current price level.

The euro posted the biggest drop in a year after speculation that Greece may refuse using the shared 17-nation European countries renewed concerns for stability of the Eurozone.

The US dollar was winner against most major currencies today as the non-farm payrolls showed that the employment growth accelerated last month, frustrating the analysts, who expected slower growth.

The Australian dollar gained today after the central bank raised its inflation forecast and signaled that it may perform an interest rates hike “at some point” in the future.

The Japanese yen retreated today, after it reached the highest level in seven week against the US dollar yesterday, on speculation that Japan will intervene to curb recent gains.

The Great Britain pound weakened after the Bank of England left its target rate unchanged, suggesting that the UK economy is still unprepared to leave accommodative monetary policy. Currently the sterling attempts to rebound, but without any significant success so far.
