This includes jewels, coins, bonds, anything that is based on something other than substance has the potential of failing. As to which countries will prevail and which not, this somewhat depends on their international reach. Those countries that have a broad international reach, and tentacles in other countries, are like someone caught in a net. They will not fall that far unless all are falling. The countries that will fare the best, and have the strongest dollar, are those that will have the least severe impact from crop shortages or the inability of commerce to proceed.

It would not be allowed to fail if others were failing, simply because it would drag the others down. However, as the island itself does not produce much of its raw materials but requires them to be imported, when it becomes a time when no one has money to buy manufactured goods, the imports will suffer, and there will be much inner turmoil on the island. The yen is likely to suffer against the dollar in this regard. China will be severely impacted. It already has trouble feeding its populace, and where the China bear was about to roar, it will shrivel down to the mew of a kitten and not again be heard from.
