The dollar slipped against the euro and other major currencies except the yen, despite U.S. data that showed a rise in inflation and a decline in initial jobless claims. The data reinforced already strong bets that the Federal Reserve will raise rates next month and several more times in 2018.
Chances of passage of a Senate tax overhaul bill rose with the endorsement of Senator John McCain. U.S. stocks, which opened higher as Wednesday's selloff in technology and other high-flying stocks reversed, took a further leg higher after McCain's endorsement. tax bill proposal, expected to reduce corporate taxes, is seen by most analysts as a boon to the stock market.
