TOKYO, Aug 22 (Reuters) - The dollar held gains on Thursday after minutes from the Federal Reserve's last policy meeting hosed down some aggressive expectations the central bank would embark on a series of deep interest rate cuts.
Asian currencies are expected to trade in tight ranges on Thursday ahead of U.S. Federal Reserve Chairman Jerome Powell's speech at Jackson Hole on Friday for signs of just how far the U.S. central bank is prepared to lower rates.
His comments are of particular interest after an inversion in the Treasury yield curve highlighted the risk that the U.S. economy may fall into recession. While the Fed's minutes tempered some dovish expectations, markets still broadly expect further rate cuts as growth slows.
"Yields are supportive of the dollar for now, but this may not last after Powell's speech," said Junichi Ishikawa, senior foreign exchange strategist at IG Securities in Tokyo.
"Additional rate cuts are thoroughly priced in. If Powell sounds slightly hawkish, stocks could sell off, which would hurt the dollar against safe-haven currencies like the yen."
At the Fed's last meeting in July, the U.S. central bank cut interest rates for the first time in a decade to 2.00-2.25%. The Fed next meets Sept. 17-18.
The dollar held steady at 107.79 yen JPY=EBS following a 0.36% gain on Wednesday, its biggest since Aug. 13.
Against the Swiss franc CHF=EBS , the dollar traded at 0.9822, close to a two-week high of 0.9831.
Fed policymakers were deeply divided over whether to cut interest rates last month but were united in wanting to signal they were not on a preset path to more cuts. this message is not likely to sit well with U.S. President Donald Trump, who has repeatedly bashed Powell for not cutting interest rates more aggressively.
Benchmark 10-year Treasury yields < US10YT=RR> gained after the minutes, but interest rate futures are pricing in a 100% probability of a rate cut at the Fed's September meeting, a 75% chance of an additional cut in October, and a 48% likelihood of another cut in December, the CME's FedWatch tool shows.
The Fed and other central banks are cutting interest rates to contain a global economic slowdown caused by a prolonged trade war between the United States and China.
Sterling traded a tad lower at 91.89 pence per euro EURGBP= , on course for its second day of losses, as uncertainty about Britain's divorce from the European Union weighed on the pound.
Against the greenback, sterling GBP=D3 was little changed at $1.2132.
French President Emmanuel Macron said on Wednesday there would be no renegotiation of the terms for Britain's exit from the EU.
British Prime Minister Boris Johnson is due to meet Macron in Paris on Thursday. German Chancellor Angela Merkel challenged Britain to come up with alternatives to the Irish border backstop within 30 days after meeting Johnson on Wednesday.
Johnson, who won the premiership a month ago, is betting the threat of "no-deal" Brexit turmoil will convince Merkel and Macron that the EU should do a last-minute deal to remove the Irish backstop.
