Food could be a good hedge... light weight/dried foods with long shelf life, alot of them, followed by really cheap essential products. Like solar energy powered light bulbs, solar chargers, cheap security gadgets,
Food are my favorite though. Whether sold or not you still have nothing to lose as you can depend on them and not spend much on feeding. .
You mean like tinned stuff that theoretically never expires. Uht milk (it's the UK, no one will go without a milky tea for long even if its disgusting) or syrup and sugar which also don't really go off (maple syrup has a date of about 100 years).
You kinda need fruit though at some point...
I think a few will go, it could be anything related to technology, aside that real estate and lands too can go a long way too, cause they are always in constant need. Anything that has to do with nature, but bear in mind that crude oil is way over rated. Energy derived from nation (solar) is also part of it.
Yes oil isn't a great hedge as we already have electric cars which are cheaper to run and they'll probably come down in price in a few years.
I wouldn't necessarily think that commodities are great bets. Especially when you have perishables.
The thing is that, if you are spending your money on emergency food supplies (like certain preppers are already doing at this moment), you are taking a huge gamble that a very specific scenario will occur in the next financial crisis. You've also got a time limit on this hedge, since even though these food supplies can last a long while, they don't last forever.
Also, in a deflationary scenario, is it really likely that having such high amounts of food stacked up is going to help you in any way? Probably not. Keeping some emergency food/water supply is good, but I wouldn't go overboard and see it as a financial hedge, since it is simply completely illiquid.
As to oil - I agree. Not only what you've already mentioned already, but also the fact that you're likely not going to hold it in physical form means that there is a counter party risk present.
