Here's the worst I've ever heard of:

https://en.wikipedia.org/wiki/Hyperinflation_in_Zimbabwe

Yes, you read that right:

"However, Zimbabwe's peak month of inflation is estimated at 79.6 billion percent month-on-month, 89.7 sextillion percent year-on-year in mid-November 2008."

I recall interviews with government employees, who were quitting in droves. The Government wasn't keeping up with inflation, so at the end of 2 weeks, your check was basically worthless.

The place was falling apart.

People would run to the bank, cash pay checks, and buy STUFF. Anything. Anything physical. TVs, couches, bikes, blenders, ANYTHING. In one interview, a woman's living room was filled with random pieces of furniture, stacked to the ceiling, and a TV.

To trade. For barter.

Because even an hour later, that paycheck was worth so much less.

Madness.
