I write the following Courier Contract:
Item i want hauled: <-900m ISK> (yes, negative 900m ISK)
Ship to: <Same station> (yes, not moving it anywhere)
Reward: <50m ISK>
Collateral: <-1 Plex> (yes, negative 1 Plex)
Expiration: <3 days>
Days to Complete: <1 month exactly> (yes, not less than but equal to)
If you accept this then you would receive negative 900m to haul (i.e. give me 900m ISK) whilst the you put negative 1 Plex up as Collateral (i.e. i put 1 Plex up as Collateral) and i put 50m ISK aside as collateral for the fees.
After 1 month exactly you complete the "haul" and return the -900m to me (i.e. i give you 900m) and i award you with 50m fees, and so i get back my 1 Plex Collateral.
If the contact fails then you get the Plex.
The problem with a Bank today in Eve
At its simplest, banks bring together people with surplus money (savers) with people who want to borrow money (borrowers).
What Eve does not have is that Central Bank.
Actually, that is not quite true. Eve does have certain trusted third parties that act as the middle man when loans are taken out, for example.
One small addition to the Contracting System could change that
However, with a small change to the contracting system we could have a banking industry up and running.
The small change needed would be for Courier Contracts to be allowed to courier to and from the same station, be able to Courier negative ISK, for negative Collateral and the "days to complete" be set as exact times.
So, lets assume i am a Bank and you are a Saver, and i am offering 50m interest over one month for 900m deposits (=5.6% interest).
So, as a Bank i would put in the Contact system:
Item i want hauled: <-900m>
Ship to: <Same station>
Collateral: <-1 Plex>
Expiration: <3 days>
Days to Complete: <1 month exactly>
A saver would accept that and so receive negative 900m to haul (i.e. give me 900m ISK) whilst the saver puts negative 1 Plex up as Collateral (i.e. i put 1 Plex up as Collateral) and i put 50m ISK aside as collateral for the fees.
In effect, i have received 850m (900 - 50) whilst one of my Plexes is tied up for one month. I need to turn the 850m into 950m to breakeven.
After 1 month the Saver completes the "haul" and returns the -900m to me (i.e. i give the saver 900m) and i award them 50m fees, and so i get back my 1 Plex Collateral.
If the contact fails then the Saver gets the Plex.
In effect, i have paid the saver 50m interest for 900m 1 month deposit.
That is a Bond, how does it become a Bank?
The above is actually more like a bond (fixed loan with collateral) - turning this into a bank merely requires a series of the above to happen.
The Bank could write new courier contracts every 7 days (i.e. 5 courier contacts on day 1, another 5 on day 8, another 5 on day 15, another 5 on day 22, another 5 on day 29 etc etc giving deposits of 21bn) and so about 20% of the deposits are withdrawn each week (5 contracts complete) hopefully replaced by an inflow from the 5 new courier contacts accepted.
And so we have a bank.
If anyone can see a flaw in my thinking then i am all ears.
Who would want to be act as such a Bank?
Business players (traders / manufacturers) in a corp who had surplus Plex and could give a steady interest income to corp mates who had other things to do (liek blow up ships). In effect, good traders / manufacturers / business players would be of value to corps looking to provide additional benefits to members.
Anyone who had surplus Plex (like me) and just wanted the fun of being a Bank.
What is the downside for the saver?
If the price of Plex falls below the deposit value - then the Bank would be tempted to take all the ISK to another character and so the contract would fail leaving the Saver with a lower valued Plex.
But the point here is that perhaps we have could have a system in place where Savers are much better protected and so able to participate in a banking system with much more confidence.
How does this add content to the game?
ISK lying around unused would be put to use by the Bank to try and earn the interest to pay the Saver.
Failed banks would see Plex be transferred to someone who is more likely to use it (as game time or to sell to generate ISK).
What will this do for the price of Plex?
If we assumed some banks fail then Plex would be transferred and some likely sold - so, if anything, puts downward pressure on Plex. Or you could have a load of players wanting to become Banks and so buying Plex for the collateral.
