September Fed bets jump to 1-in-3 from zero as Yellen speech key - BBG

Bloomberg reported earlier on the day that traders see one-in-three odds of higher Fed  rates next month as more Federal Reserve officials joined the chorus arguing the case for policy tightening before Chair Yellen speaks Friday.

The formal topic of Yellen’s remarks -- “The Federal Reserve’s Monetary Policy Toolkit” -- implies a technical focus on the challenges facing the central bank in an era of tepid growth and low inflation.

Investors will scrutinize any description of the economy in the chair’s first public comments since June that will clarify if the Fed remains on track to raise rates later this year. Its next meeting is Sept. 20-21.
