1) Deflation (counterring the previous printing, some money is withdrawn in exchange with bonds) costing NM and VP but reducing inflation (and this should be the only way to reduce it)
2) Bank Loan (The opposite of money printing) from banks, costing no NM or VP, raising money but NOT the inflation, then when the loan expires you pay it back with interests month after month.
3) Economy Subsidies, invest a part of your cash to increase output of a specific supply: General/War/Ammo (alias: Convert your money into a specific supply increase in next turn by commissioning specific factories to build specific supplies in place of the supplies they generally build)
4) Import resources, spend cash to buy war supplies abroad (a lot expensive).
I don't know if it's possible or historically accurate, was just thinking it would be handy...
