Asian currencies traded in a tight range against the dollar in a week with few leads although the Indonesian rupiah dropped sharply on soaring world oil prices.
The Japanese currency stood at 109.78-80 to the dollar late Friday, compared with 110.80-83 to the dollar a week earlier.
"The dollar saw a little selling pressure on the mixed US indicators," said Masamichi Koike, head of the trading department at Sumitomo Mitsui Banking Corporation.
"Market participants became concerned over consumption due to higher oil prices," said Koike. US oil futures hit record highs close to 68 dollars a barrel before closing at 66.13 on Friday.
Orders for US-made durable goods tumbled 4.9 percent in July, but the number of new US home sales in July surged by 6.5 percent, data showed Wednesday.
But investors sold the yen on Friday as the market showed concern at a report that Al Qaeda may be preparing an attack on a financial center in Asia, dealers said.
France's top terrorism investigator, Jean-Louis Bruguiere, told the Financial Times that several Asian countries, including Japan, were less prepared than the United States or Europe for a possible terrorist strike.
"We have elements of information that make us think that countries in this region, especially Japan, could have been targeted" by the al Qaeda network, the investigating magistrate said.
With little other news to drive markets, the report weighed on the Japanese currency, dealers said.
At 5:00 pm Friday (0700 GMT) the dollar was trading at 75.87 US cents, more than half a cent above last week's 75.19 US cents.
Movement in the coming week could be prompted by the release of domestic data - including monthly retail trade figures and current account data for the June quarter - as well as US construction spending figures.
Comments from US Federal Reserve chairman Alan Greenspan over the weekend could also have an impact.
Dealers said the won is likely to move within a range of 1,025 won and 1,032 won in the coming week.
