I think it's important to note that these banks aren't acting all by themselves when they're 'creating' this money. They're working alongside the Federal Reserve to be allowed to just electronically create the funds. The fed knows how much money is being created, and there is regulation when this is done. it's not like a bank can just send you 1 trillion dollars without any sort of oversight at all.
But back onto the topic here: Yes, fractional reserve banking is a VERY common practice in the world. Typically only comes up around common people when there is some sort of bank run. But ya know, in the US and EU there is the FDIC / EU backing of funds in the bank (up to 250??k in the us, and 100k in the EU)
Yeah insurance on savings is a thing here, it's generally per bank per person too...
So the £86k limit of FSCS protection is just per entity relationship (citizen number to bank).
Yeah, same thing as here.
If I had 10 bank accounts at 10 different banks, in theory I could have 2.5m in coverage from the FDIC in the event of some sort of horrid bank crisis and bank run. So yeah.
Not sure if FDIC has ever had to make large payouts, but at least it's their.
