Expectation of supply disruptions due to both panic and supply chain breakdowns. I don’t see things getting totally out of control, but what is available might be limited. Everything I have bought I will use up over the next 6 months anyway so no loss.
You might read up on the Bullwhip Effect. these demand fluctuations can have very disruptive effects on supply chains and availability of things, even if nothing else happens. So I highly disagree with the "no loos" statement. Not you personally, but as group behavior these stock ups caused probably more mid term supply issues on everyday stuff than the Corona virus so far.
