The greenback recorded a six-month high against the euro , buoyed by another drop in oil prices and growing views the U.S. economic slowdown may be bottoming while growth in the euro zone stalls.

The US dollar posted a fifth week of gains against the euro as investors shifted their view on the global economy's ability to withstand a downturn initiated in the United States. The greenback has rallied nearly 6% against the euro this month.

Data in the U.S. on Friday showed an unexpected rise in manufacturing activity in the New York state area and an increase in industrial output and consumer confidence. By contrast, reports on Thursday showed the euro zone economy contracted in the second quarter for the first time since the common currency's inception.

The Bank of England this week also warned of economic slowdown ahead and Japan said its economy contracted in the second quarter at the sharpest rate in seven years.

A steep drop in commodity prices also has lent support to the dollar because it helps ease concern about the U.S. economic outlook in the second half of the year.
