The food crisis is right around the corner. I'd put all my money in food commodities.
Not a bad idea to invest in food commodities, and this has been advocated by many wealthy, smart investors, like the famous Jimmy Rogers.
The only problem that I see, based on my trading outlook, is that you basically have to invest in paper products to do what you advocate. Whether it be futures, stocks, etc, it is not really possible to buy and store bushels of corn, wheat and soybeans for the average person. If someone could buy actual farmland and such, then that would probably be better than physical PMs, that is if they could properly maintain and afford to buy such land.
My fear is that at some point in the future due to possible collapses of financial markets, etc, paper instruments and trading vehicles could suffer some unforeseen calamity and folks might have a hard time collecting on their winning positions. I am not saying we will have a Mad Max scenario, but that said paper positions might take time and sorting out to finally collect on, whereas physical items in your possession are available to you at any given time. With a paper trading vehicle there is almost always something called counter-party risk--meaning it is possible one party involved in the transaction might not live up to their obligation.
We all have to accept said counter-party risk to some extent in our modern world, such as our FDIC insured bank accounts and such, but when it comes to TSHF investments, I still would prefer physical gold and silver over anything right now, other than the actual farm land itself which I could not afford nor maintain under my current living situation.
If I was very rich though, I would have no problems putting a portion of my investment dollars into paper commodity plays but would still keep the majority in physical PMs.
All just my opinion.
