Quantitative tightening is no substitute for higher interest rates

Reversing trillions of dollars of asset purchases may prove to be an unreliable tool

On January 26th the Federal Reserve said it would end QE soon and gave guidance for the first time about how it might shrink its balance-sheet, a process dubbed quantitative tightening (QT). Reversing trillions of dollars of asset purchases might seem like a powerful way to contain inflation. In fact QT will be an unreliable tool.
