The US dollar index rose to a seven-week high, supported by strong US data, a day ahead of the September job report.
"The US trade deficit fell, with exports of goods and services rising to a two-and-a-half-year high, while the number of Americans applying for unemployment benefits fell more-than-expected last week," the Commerce Department said.
New orders for US-made goods rose in August, and capital goods orders rose more strongly than the initial reading, suggesting strong corporate spending could help reduce the impact of Hurricane Harvey and the economy on the economy.
The dollar index, which measures the value of the greenback, rose against a basket of six major currencies, to 93.989, the highest level since August 17.
The greenback has also been supported by higher yields on US Treasuries, and Wall Street stock indexes have recorded new record highs.
The pound fell 1 percent against the US currency to $ 1.3116, its lowest level in four weeks
