The World Federation rely a lot on money from wealthy patrons to fund research and development, State's financial & social needs.
The Federation’s ambitions (and the IBOCR) convince “Patrons” to assemble and work together in various fields and make first contribution to fund the Federation in its early establishment, notably during the Unification Wars.
This way money is re-invested, and this behavior is usually pushed by the government with advantages like class S, specific privileges.
Also, patrons who finance the World Federation may have a spot on whatever survival project the World Federation develops in case of natural disasters.
Money that “sleeps” in banks over a certain amount has a percentage to be reinvested in research and development annually as, per the Federal laws.
This encourages research and technology development and patrons usually fund students who do research, usually they are also a legal warrant of the student in that case.
Black Treasury is the personal patronage from MT's initiative, built from BORCI and various private investments to fund the IBOCR, Pro-Federal States in need of financial support.
