What is “Operation Twist?”

The Federal Reserve will swap $400 billion in Treasuries that come due in three years or less for $400 billion in Treasuries that come due in six years or more.

Why would they want to do this?

Right now, there are trillions of dollars in corporate reserves sitting on the sidelines. If corporations decided to invest that money in new workers, plants, etc., it would be a huge boon to the recovery. But they’re scared to invest now because the future of the economy is so uncertain. By purchasing long-term bonds, the Federal Reserve is trying to make it less profitable to stash your money in Treasury securities and give investors and businesses an added reason to spend now, when interest rates are low.

See Neil Irwin and Michael Birnbaum for more on that.

Why is “Operation Twist” called “Operation Twist”?

Financial writers like to be cute. The Financial Times’ Gavyn Davies, for instance, wrote about an alternative path the Fed could have taken in which they clearly communicate their intention to attack unemployment until it begs for mercy and called it “Operation Shout.” Get it?
