0235 GMT - The Singapore dollar consolidates against its U.S. counterpart in the Asia session ahead of Fed Chair Warsh's speech at Jackson Hole later today. "Uncertainty over the Fed's reaction function and concerns that policymakers may be placing less emphasis on inflation control have increased market focus" on Warsh's comments, two strategists at OCBC Group Research say. "The USD could find support if Warsh and other Fed officials push back against currency debasement concerns and reaffirm their commitment to returning inflation to the 2% target," the strategists add. The U.S. dollar is little changed at 1.2706 Singapore dollars, LSEG data show.
