The US dollar retreated for a second day in Asian trading on Tuesday, as market jitters from US military action in Venezuela eased and dovish comments from Fed officials spurred risk-taking on Wall Street.

The dollar index, which measures ​its strength against a basket of six currencies, was last trading at 98.216, down 0.2% and extending ‌losses after snapping a four-day winning streak on Monday.

Financial markets are settling down after the shock US capture of Venezuelan President Nicolas Maduro over the weekend sparked volatility in commodity ⁠markets. Maduro pleaded not guilty to narcotics charges in a Manhattan federal court on ⁠Monday.

Against the yen, the US dollar was last off 0.1% at 156.255 yen, with the greenback weakening slightly following an auction of 10-year Japanese government bonds, which drew demand in line with the average ​over the past year.

The Australian dollar, which is sensitive to commodity prices, was last up 0.1% at a one-week high of $0.6724, nearing the highest in more than a year after copper prices hit a record.

The New Zealand dollar was last up 0.2% at $0.5798.

The greenback retreated after hitting the highest levels in a month during Monday's trading session, as US manufacturing ​activity contracted more than expected in December and fell ‍to a 14-month low.

The dollar was further ⁠pressured on Monday by dovish comments from Minneapolis Federal Reserve ​President Neel Kashkari, a voter on the central bank's rate-setting committee this year, who told CNBC he sees a risk that the jobless rate could 'pop' higher.

Expectations ​of policy easing edged up after his remarks, though Fed funds futures are still pricing ‍an implied 82.8% probability that interest rates will remain on hold at the US central bank's next meeting on January 27 to 28, compared to an 83.4% chance on Friday, according to the CME Group's FedWatch tool.

Against the Chinese yuan trading offshore in Hong Kong , the US dollar was last down 0.1% at 6.9769 yuan.

The euro was last up 0.1% at $1.1737, ‌while the British pound strengthened 0.2% to $1.3562.

Bitcoin was last down 0.3% at $93,772.04, while ether slid 0.4% to $3,225.96.
