The Canadian currency, which was losing earlier versus the U.S. dollar on pessimism before the G-7 meeting, managed to revert a losing trend as the crude oil rates surged beyond $70 a barrel, raising attractiveness for the loonie.

The United States is one of the main destination for Chilean commodity exports, and negative reports towards the end of this week coming from the U.S. affected negatively the South American currency performance.

The pound has been one of the most affected currencies by the credit crunch last year and during the past three weeks it suffered another substantial decline as the U.K. economic scenario continues to deteriorate and this Friday risk aversion is high again pushing investors towards safety.

The Brazilian currency touched a one-year high versus the dollar and the pound this week but was unable to continue its rally as U.S. jobless claims came worse than what economists expected, decreasing appeal for emergent market high-yielding currencies.

This Thursday was marked by a weak performance for the Mexican currency as the crude oil, one of the main Mexican exports to the U.S. declined further, and jobless claims in the U.S. came with worse-than-expected figures.

The pound managed to pare early losses versus the euro and the dollar after the IMF affirmed that the United Kingdom will grow more than previously announced for the next year, adding confidence for the British Isles economies.

The euro, which has been one of the strongest currencies among major pairs this year, fell today before speculations suggested that a Group of 7 finance ministers meeting this week will approach the current euro strong valuation, raising concerns and damping demand for the Eurozone currency.
