What might link these
A strong correlation exists between a country's GDP and its total reserves. Larger economies often have more capacity to accumulate reserves through trade surpluses, investment, or currency interventions. However, this correlation is not causal and can be influenced by many factors.
Why this is not proof of anything
This is a correlation across countries, not an experiment. It cannot show that either indicator causes the other, and both may simply follow a third thing. The significant partial correlation indicates that the relationship persists even after accounting for population and GDP, but it does not prove a direct causal link or rule out other influencing factors.
The second figure above repeats the measurement with national population and income held constant. It is the more conservative number: a relationship that largely disappears there was mostly telling you that larger, richer countries have more of most things.
How this was measured
Both indicators were ranked across every country reporting each, and the two rankings compared — ranks rather than raw values, because a handful of very large countries can otherwise manufacture a relationship on their own. The calculation is arithmetic over figures already published on this site; the commentary above is drafted from the two indicator names and the resulting coefficients.
