If everyone who didn't have a stash before is suddenly stocking up for a months supply of everything, you get shortages. The right way to build up your supplies is slowly over time.

Indeed FEMA is now asking that folks only buy a weeks worth of groceries: https://www.mercurynews.com/2020/03/23/coronavirus-new-guide...

Over here in Germany the recommendation has always been to have supplies for 10-14 days at home. Seems like a more reasonable number than a months worth - especially for city dwellers.

That's indeed the right solution. But it needs to be enforced by the stores - as many do now, with per-customer purchase limits.

That's a nice recommendation for a calm time, but a bit short for the pandemic. If you get quarantined, you need to stay put for 14-21 days. Add a bit of padding to account for undersupplied stores (and to add a margin for error), and you arrive at 1 month's worth.

We've seen this coming since at least early February. That's exactly when I started stocking up, buying ~2x amounts of non-perishables (e.g. 2 packages of pasta) instead of waiting for the impending hoarder shitstorm at the very last minute. I forget where I read this recommendation (WHO?), but it has definitely paid off, I haven't been to the store in almost 2 weeks :)

That assumes you have absolutely zero access to groceries for those 14-21 days. But there are still delivery services and neighbors. In Germany, city governments have actually delivered food to those quarantined.

I'd say that's a safe assumption to make. On top of that, even contactless delivery by via service or neighbour has nonzero risk of communicating the disease (in either direction), so it's worth minimizing the need for it.

Interesting. Here in Norway the recommendation has been to keep supplies for 3 days, including water, power supplies (battery banks), a radio with full batteries, heating and cooking possibilities and so on.

I agree with you. People have been hating so much on hoarders, while not acknowledging that the real problem is that people are way too reliant on a just-in-time supply chain. It's really not that difficult, expensive, or space-consuming to have a buffer of at least one month for scenarios like this. Yet, most people don't build up this buffer over time, out of laziness, and then they go around blaming others for the shortages during a crisis (or they go panic-hoarding themselves).

I used to go to work every weekday, and eat 2 meals there. Now I'm at home 24/7, so I'm already eating 5x the amount (before this, I would barely eat at home). Also, my girlfriend is here with me. I used to have a many months' worth of stock in the pantry, but now it turns out that it's just enough for two weeks.
