The dollar nursed losses against the yen and euro on Tuesday, but was firmer versus the Canadian and New Zealand currencies, which succumbed to weakness in commodity prices.

The greenback has been on the defensive as views that the U.S. central bank is in no hurry to tighten monetary policy have held sway ever since Federal Reserve Chair Janet Yellen last week expressed caution toward hiking interest rates.

The dollar came under further pressure against the safe-haven yen as equities and crude oil prices fell.

Perceptions that the Bank of Japan would not immediately ease monetary policy, which in theory would curb yen strength, further favored the Japanese currency.

The Australian dollar nudged up 0.3 percent to $0.7623 from an intraday low of $0.7568 after the Reserve Bank of Australia left its cash rate unchanged at a record low 2 percent as widely expected. The Aussie drew a bit of relief as the RBA resisted talking down the currency's recent strength as some had feared. Yet Boston Fed President Eric Rosengren on Monday warned that the interest rate futures market could be "too pessimistic", noting external risks to the U.S. economy seemed to be abating.
