TOKYO, June 5 (Reuters) - The dollar struggled near seven-week lows on Wednesday after U.S. central bank officials hinted at the possibility of an interest rate cut in the face of rising risks to trade and global growth.
Federal Reserve Chairman Jerome Powell dropped his standard reference to the Fed being "patient" in approaching any rate decision on Tuesday, saying instead the central bank will respond as "as appropriate" to trade pressure.
The dollar index against a basket of six peers was last flat at 97.077, within reach of a recent low of 96.995 brushed overnight - its lowest since April 18. It has now fallen 1.3% from a more than two-year high of 98.371 touched on May 23.
Masafumi Yamamoto, chief currency strategist at Mizuho Securities, said major currencies barely reacted to Powell's comments as investors had already priced in several rate cuts by the Fed on the back of the shifting global growth outlook.
The Fed chairman's comments came a day after St. Louis Federal Reserve President James Bullard said in a speech that a rate cut may be needed "soon."
Rate cuts by some central banks in recent weeks could potentially signal the start of a global monetary easing cycle to stave off a sharper economic downturn.
"Central banks across the globe are adopting a dovish tone. It's kind of a preemptive move," said Yamamoto.
"It doesn't necessarily mean that the economy is worsening – rather the outlook worsened. It's mainly related to the trade tensions between the U.S. and China and the U.S. and Mexico."
Australia's central bank on Tuesday slashed benchmark cash rates to a record low of 1.25% and signalled willingness to go further if the worsening outlook persists.
Last month, New Zealand's central bank cut its benchmark interest rate for the first time in two-and-a-half years as it moved to support a cooling economy and counter global uncertainties.
In South Korea, its central bank last week kept policy settings unchanged but adopted a more accommodative tone while India is expected to cut rates at its policy meeting on Thursday.
On Wednesday, the Australian dollar rose 0.15% to $0.7000 despite data showing growth in the Australian economy picked up only modestly in the first quarter while the annual pace was at its slowest in a decade.
The A$1.9 trillion ($1.3 trillion) economy expanded 0.4% in the three months ended March, while annual GDP rose 1.8%, the weakest since the global financial crisis.
