Banking requires minting coins with speed and precision, which transitions into more general techniques in making replaceable parts.
In a word, no. Banking, in a loose-ish sense (institutions or individuals involved in the extension of credit) predates coinage by more than a thousand years.
Though, I think you're right about CS and maces. The way I think of it is that the units prior to maces are "primitive" or low-impact enough that they can forage for themselves, whereas fielding maces requires some provisions for logistics, which in turn requires some bureaucracy. It's a bit shaky, as bureaucracy predates alphabet and probably writing, too, but it works if you don't squint at it too hard.
Banking is required for Replaceable Parts because replaceable parts were historically developed to make production easier and faster, which is just what you'd expect when the emergence of modern banking systems, symbolized by the discovery of Banking, puts investors, who are looking to turn a profit, in charge of production.
Conceptually, we can see the Banking--> Replaceable Parts progression as an abstraction of the historical progression from proto-capitalism with all its novel financial instruments to the beginnings of the industrial revolution.
