• U.S. Federal Reserve left its key interest rates unchanged at 1.25%, but made clear it will start to unwind its $4.5 trillion balance sheet next month. The move is expected to reduce liquidity in the markets, although the Fed suggested it will move slowly so as not to spook investors. The Fed said it will not reinvest the proceeds from its bond portfolio and allow $10 billion to roll off at the beginning. It will gradually increase that amount by $10 billion per quarter until it hits $50 billion. The Fed also cut inflation expectations from 1.7% this year to as little as 1.5%, below its target of 2%. In 2018, it expects inflation to hit 1.9%. The central bank also did not rule out another interest rate hike this year.

• Bank of Japan kept its ultra-loose monetary policy steady and struck an upbeat tone about the economy. BoJ suggested it was on track to reach its goal of 2% inflation.
