Currency Mechanic

To establish currency we have  to establish central bank. The role of central bank is to store your and foreign currency and trade currencies.

Central bank will have repo rate which we can fix and repo rate is loan taken by public bank from central bank.Here public bank shows expense going toward public which can be controlled. I choose this because anyother term not seems to be suitable.

The repo rate is here is like you are lending money to public bank ([Public bank is hypothetical you need not to build it]) the extra bonus money you are getting bank means give you extra money income and it will also increase trade.

It is suggesting a flow of cash from you to public to foreign civ to back to me.

The repo rate can be adjusted to control inflation or deflation. If repo rate increase it decrease money from city decrease and repo rate decrease it increase money from city. The effect is proportional to population of civ.

Appreciation of currency value

If there is shortage of our currency in central bank, the currency can be printed or if any foreign civ invest in our currency or if we sale foreign currency. The extra inflation can be by traders approaching your civ.

Depreciation of Currency value

If we buy foreign currency from our currency and if other civ buy our currency heavily cause deflation.

If inflation or deflation will be high cause heavy trade fluctuation.

One currency will be most used in international trade.

It can be strategic tool and can cause heavy loss to civ by fluctuating price by selling or buying currency.

In begining of this mechanic currency value can be as follow

Civ A

starting A=B=C=D (ABCD are currencies)

After few turns

A>B

A<C

A>D

Civ B

starting A=B=C=D

B>A

B=C

B<D

If you see any problem please comment.

It can be done to give value to currency the gold can be first to determine the value of currency and then value will be bye exchanges of currency.

I choose repo rate because it is better way of showing movement of money from central bank to public bank.

If there is any other way please share.

My major thing is i am trying to show flow of cash and i also said trade is also bringing foreign currency which is exchanged and an income of another currency or an investment by other civ.
