The Ministry of Transport have put up a fuel monitoring dashboard. It shows estimates of demand, supply, and price.
At the moment, the reduction in demand is less than 10%, a level of demand that’s probably not sustainable in the medium when global supply is down at least 25%. On the other hand, we are still at level 1 of the alert system, and even level 2 doesn’t ask for any real reductions in demand.
What this display doesn’t show is any sort of “time to running out”. That’s probably sensible, because it’s not even well-defined, let alone predictable. If you define “running out” as some petrol stations being out of supplies then it’s already happened. If you define it as “no fuel in the country”, it probably won’t happen. And if you define it as level 3 or level 4 restrictions on supply then it’s a choice by the government based on unknown criteria, and so is hard to forecast statistically.
