0546 GMT - U.S. Treasury yields edge lower in Asian trade but continue to hover around new multiyear highs reached Tuesday as investor attention turns to a widely anticipated 25-basis-point interest-rate hike by the Federal Reserve later in the day. In particular, investors are focusing on signals on how the Fed seeks to return inflation to target. The recent rise in Treasury yields "reflect not only higher inflation expectations but also higher real yields driven by increased government borrowing and ongoing policy uncertainty," TwentyFour Asset Management portfolio manager Felipe Villarroel says in a note. The 10-year Treasury yield eases 0.2 basis point to 4.993%, according to Tradeweb, after hitting 5.041%, the highest since 2007, on Tuesday.
