"For vampires, the weakness is garlic. For werewolves, it’s a silver bullet. And for zombies? Perhaps a rise in interest rates will do the trick.

The fundamental concern is that there are companies which should be dead, yet continue to lumber on, ruining things for everyone. It’s a vivid metaphor — perhaps a little too vivid — and it is likely to be tested over the months and years to come if, as almost everyone expects, central banks continue to raise interest rates back to what veterans might describe as “normal”.
...
 the tendency of low interest rates to sustain zombie companies.[Moi ici: Quanto mais baixas as taxas de juro menor a exigência de rentabilidade, menor a exigência de risco, menor a exigência de pureza estratégica]
...
low interest rates seem conducive to the existence of zombies, which they define as older companies that don’t make enough money to service their debts. As interest rates have fallen around the world, such zombies have become more prevalent and have also shown more endurance.
...
 It is necessary that the zombies must die, but that cannot be where the story ends."
