Zombies are neither dead nor alive. They should be dead. But some magical — often evil — forces keep them alive.

Zombies have appeared in horror movies and books for centuries. But now they are in the business world.

A zombie company is one that should be dead but somehow manages to survive — even when sales don’t cover the costs of debt.

Thirty years ago, analysts didn’t think zombies could exist. They argued rational investors would not fund companies that can’t pay off debt.

But that no longer applies.

According to the Bank of International Settlements (BIS), the central bank to the world’s central banks, zombies are a growing problem. Their economists have a knack for finding problems before others.

BIS officials started warning of zombie companies in 2002. They first appeared in Japan, created by low interest rates. Investors searching for gains funded bad businesses.

BIS is concerned that unprofitable firms hurt the economy. Zombie companies, like their counterparts in movies, are the walking dead.

In the BIS’ economic terms: “If low interest rates keep ‘zombie’ companies alive, and prevent the needed reduction in excess capacity, then profits will not recover. And without profits, there can be no economic rebound more generally.”

Zombie Companies Provide a Unique Investment Opportunity

Although it’s a global problem, the United States has a higher than average number of zombies. BIS data shows that at least 12% of all companies in the world are “zombies.” That number jumps to 19% in the U.S.

And potential zombie killers are avoiding the fight right now.

According to CNBC, zombie companies employ about 2.2 million people. Letting the companies die adds to unemployment. Keeping them alive delays a full economic recovery.

Federal Reserve policies create and sustain zombies. For now, the Fed can’t reverse course and push millions into unemployment.

Easy money is the magical — and somewhat evil — force keeping zombie companies alive. But long-term investment returns will be low. Look at Japan.

The good news for investors is that many zombies will fail.

Put options can offer large gains when that happens.
