Obviously the main concern here is always the effect on one's own personal wealth, which almost always turn to "how much gold to hold".
I would submit that this would be almost immaterial if global wealth were to be monetized.
Understanding negative interest rates is a good entry into understanding the possibility that this could happen.
While gold is the most obvious standard medium, it is not the only one.
This three year old article lays out projections that thusfar have not happened, but as far as I can see, there is no reason that the basic premise is not correct.

Failed countries, failed economies and failed unions are headlined every day, and yet little has been said about the underlying financial struture being close to failure, except perhaps the recent staus of Greece. How much more unstated risk is involved? China, Russia, Venezeula, Japan, as well as many Middle East, Asian, African and South American countries.
It is not always the national debt of the countries... ie: Russia,with little longterm debt. but the instability of the governments.
The timetable is in the hands of the Central Banks...some living on a wish and a prayer.The IMF? Therein lies another deep study . Select your sources carefully.The magic continues... Another year? Another ten years? or tomorrow morning?
For every scholarly piece that backs the internationality of the money system, there is another the paints debt monetization as a pending disaster.
Little to be done at the individual level, excapt to watch for longer trends that could turn negative. In any case... the words to watch for are "debt monetization".
