Given the donations /β year figures, these seem relevant:
World Bank expenditures (inc. loans) per year: $10^11 ($61 billion)
UN expenditures per year: $10^11 ($48 billion)
EU expenditures per year: $10^12 ($182 billion)
ADB (Asian Development Bank) expenditures per year: $10^11 ($23 billion)
I think all figures were from around 2015, so these could now be different.
Some others are much smaller and therefore not included, such as GAVI, IMF, WHO, etc.
