TOKYO, Dec 1 (Reuters) - The dollar tumbled to a three-month low versus the yen on Thursday as traders keyed on comments by Federal Reserve Chair Jerome Powell that interest rate hikes could be scaled back "as soon as December."
The dollar-yen pair is extremely sensitive to changes in long-term U.S. yields, which slid to a nearly two-month low of 3.6% overnight after Powell said at the Brookings Institution in Washington that "slowing down at this point is a good way to balance the risks." He added however that controling inflation "will require holding policy at a restrictive level for some time."
The greenback was 0.48% lower at 137.39 yen in the Asian morning, after earlier dipping to 137.27 for the first time since Aug. 26, with yields on 10-year Treasury notes standing at 3.62% in Tokyo.
"Market participants appear to have interpreted Powell's speech as more dovish than hawkish," pushing down U.S. yields and the dollar, Kim Mundy, a strategist at Commonwealth Bank of Australia, wrote in a client note.
"The reaction supports the markets' apparent 'glass half full' approach to the economic outlook at the moment."
Markets are currently pricing 91% odds that the Fed slows to a 50 basis point rate increase on Dec. 14, and just 9% probability of another 75 basis point bump.
In November, the dollar dropped 7.15% versus the yen, its worst month in 14 years, as investors positioned for a Fed pivot.
The dollar index - which measures the currency against six major peers including the yen and euro - extended Wednesday's more than 1% drop into Thursday, dipping as low as 105.69. It tumbled 5.2% in November, its worst monthly showing since September 2010.
The euro rose 0.21% to $1.04325, and sterling added 0.23% to $1.2086.
A European survey on Wednesday showed that euro zone inflation eased far more than expected in November, raising hopes that sky-high price growth is now past its peak and bolstering, if not outright sealing the case for a slowdown in European Central Bank rate hikes next month.
The risk-sensitive Antipodean currencies gained, with the Aussie dollar last 0.17% stronger at $0.6800, after earlier touching $0.68145 for the first time since Sept. 13. New Zealand's kiwi added 0.32% to $0.63175, the highest since Aug. 17.
The Aussie and kiwi have also been buoyed by signs the Chinese government will relent on its strangling zero COVID policy, following the announcement of an easing of curbs in places including Guangzhou and Zhengzhou, the site of a Foxconn iPhone factory.
