Fed rate decision uncertain as markets divided

Financial markets face unusual uncertainty ahead of the U.S. Federal Reserve's interest rate decision, as Fed Chairman Kevin Warsh has given no clues on his rate path. Market bets show a split between a rate hike, which would align with Warsh's 'no tolerance' stance on inflation, and a more likely hold that signals patience. Typically, Fed decisions are well-telegraphed, but this time remains unpredictable.
