From Fed Governor Kevin Warsh: It’s Greek to Me In my view, any judgment to expand the balance sheet further should be subject to strict scrutiny. I would want to be convinced that the incremental macroeconomic benefits outweighed any costs owing to erosion of market functioning, perceptions of monetizing indebtedness, crowding-out of private buyers, or loss of central bank credibility. The Fed’s institutional credibility is its most valuable asset, far more consequential to macroeconomic performance than its holdings of long-term Treasury securities or agency securities.
