Harnett offered a thumbnail of just how prolific global central bank intervention has been:
• 637: Rate cuts since Bear Stearns imploded in March 2008.
• $12.3 trillion: Asset purchases through global QE programs.
• $8.3 trillion: Global debt yielding zero percent or less.
• 489 million: Population of countries with official policy rates of less than zero.
• -0.93 percent: Yield on the two-year Swiss bond, the lowest-yielding government debt in the world.
