0637 GMT - The dollar trades steady but remains near recent seven-week highs, lifted by the prospect of the Federal Reserve raising interest rates further. Chicago Fed president Austan Goolsbee said Monday that another 25 basis points rate rise likely wouldn't be enough if inflation was being driven by more enduring factors than higher energy prices. St. Louis Fed president Alberto Musalem said further rate increases were needed to rein back inflation. The comments come after the Fed lifted rates by 25 basis points last week and penciled in at least one more hike this year. The DXY dollar index trades flat at 100.457, having risen to as high as 100.564 on Friday.
