If bitcoin becomes a world reserve currency then its ok but dont try to ally it with fractionals systems.. is the last thing we want in bitcoin, debt , crisis and useless monetary system
No reason why BTC based fractional banking would not work in the new world order. The primary difference would be that if a bank could not deliver on it's obligations, it would be out of business, no government to print up a few more notes out of the ether. So I think in practice fractional reserve banking would happen (because it's good business to gear up from a banks point of view), but at a very low/sensible fraction 1/2->1/4 range. not the 1/10->1/20
banks are currently running at worldwide.
Also, since traditional 'current account' retail model of banking would be out of the window, then deposits would most likely be based on interest baring savings accounts with controlled withdrawal lockins, so the whole banking model would be less volatile because there are no current accounts to 'have a run on' and scaled down.
This is exactly right.
It is the FED's printing press, and only the FED's printing press, that enables banks to operate at the 1/10 to 1/30 ratios we see today. The reason is markets do not worry about a bank running out of capital because the FED can and will provide "liquidity" on demand.
If a bank operates at 1/30 and runs out of core capital, the bank can swap assets as collateral for dollar funds at face value with the FED. Because of this, banks could run on infinite leverage and it is only regulation which limits them. The system is designed to enable the FED to stop any and all bank runs in their tracks, and as a result there are no bank runs.
In a sense the leverage reported is just an fictitious accounting trick and is not real since the FED can and has simply created money "on demand" as needed for liquidity. If the FED took this away, every single bank would go under within 24 hours. That is exactly what happened to Bear Sterns in '08, the FED decided they needed to make an example of one IB that went too far, selected Bear and said they would not back them further, and Bear was bankrupt in hours.
Under a sound money system banks by necessity keep leverage less than 1/2, because otherwise they could not stop a run since there is no FED to provide "on demand" "liquidity". This was the banking system pre-FED. This would be the banking system under bitcoin. Leverage would be very low and fractional used money would be in line with base bitcoin money.
