Zombie companies are back — and they’re multiplying fast. Across America, 639 firms can’t even pay their interest bills anymore. These “zombie companies,” tracked by Bloomberg through the Russell 3000 Index, just hit their highest count since late 2021. That’s 83 more firms turning into zombies in October alone. The reason? High interest rates that just won’t come down. For years, cheap credit kept weak companies alive. Now the easy-money lifeline is gone, and debt costs are crushing them.
