How close to zero can I push private capital and not get inflation?

[Dave3L]

I'm trying to work out the economics of the game, and last night I think I figured out how to balance trade/domestic sales and not run my stockpile of gov't and private capital to 0. So, after saving up 850 or so private capital, I bought a factory and thought I wouldn't get inflation.

Wrong. So, how much of a cushion do I need before dropping that much cash on a project?

Depends of the size of your economy, something like 200 to 300 £ would be correct I believe. The game check all production structures every turn in random order, and most will cost you private capital, so if you can't pay for them you get inflation. One turn worth of upkeep would be safer, but is difficult to achieve.
