The dollar gained 0.44 of a cent to 89.06 cents US as China's economic growth slowed to a five-year low of 7.3 per cent last quarter.
That was lower than the 7.5 per cent rate that had been targeted by Chinese leaders, who are trying to steer China toward growth based on domestic consumption instead of overreliance on trade and investment. But the number was broadly in line with expectations and higher than some estimates that had pegged growth at 7.2 per cent.
Other data showed growth in industrial production was largely stable, with a rate of 8.5 per cent year on year in the first three quarters, down 0.3 point from the first half. Growth in consumer spending cooled to 11.6 per cent in September, the fourth monthly decline in a row.
On the commodity markets, the November crude contract in New York, which expired Tuesday, gained 10 cents to US$82.81 a barrel. The December contract ran up 58 cents to US$82.49.
December gold rose $7 to $1,251.70 an ounce while December copper was ahead four cents to US$3.03 a pound.
