In other news, Reuters writes "More Permanent Role Seen for Fed's Repurchase Program". The article says, "A pledge by the U.S. Federal Reserve to phase out a new tool to lift interest rates is being challenged by economists and financial professionals who think the central bank may need to keep using it longer than Fed officials expect. As the Fed approaches an interest rate hike -- expected later this year -- it will use a suite of tools, including an overnight reverse repurchase facility (ON RRP) for money market funds to help lift its traditional federal funds rate from near zero. The notion of making the repurchase program a more permanent fixture at the Fed reflects the increasing role that non-bank lenders, also known as shadow banks, are playing in the U.S. borrowing market.... The Fed has said it will shutter the repo program as soon as it's no longer needed, with Atlanta Fed President Dennis Lockhart saying on Wednesday that the central bank can adjust rates in a way to where the program "dies under its own weight." Boston Fed Vice President Joe Peek said the central bank may have to make its new tools for controlling rates a permanent feature of monetary policy."
