This indicator compares the Global (world) Monetary Supply (measured in USD) compared to the Global GDP.
This can be useful to measure the "money printing speed" of the world compare to the "world gdp growth", the higher the slope (angle of growth) the more money printing.
It includes the exact same countries of the Global M2 indicator (done by me), to make fair the comparison, which has the richest and most populous countries so to have a clear overview.
There tough a few very populated countries excluded, the details can be found on the Global M2 indicator script and reason for exclusion.
