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. 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 following a 0.36% gain on Wednesday, its biggest since Aug. 13. 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. However, 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.
