That's not necessarily true. Many G20 countries have now included bail-in laws. In NZ we have a very clear bail-in, we don't even have an amount of 'safe' deposits ie some countries allow $250k before the bank helps itself.
https://rbnz.govt.nz/regulation-and-supervision/banks/open-bank-resolution . Most of these countries are less keen on the taxpayer coping the cost of a bail-out. A depositor is an unsecured creditor and a fast and easy target to pay for the sins of the banking system.
Bail-in by depositors is new to me. In my opinion, the existence of a safe amount is actually to assure depositors and to deter bank runs. Sometimes the bank itself maybe solvent, but a bank run will cause a liquidity crunch and cause the bank to dump assets at depressed valuations.
If I’m not wrong, in Singapore, the safe amount is funded using a national deposit insurance scheme that the bank pays premium on an annual basis. It is not a government guarantee. In a way, it is still being funded by depositors and shareholders.
Unlike Australia and NZ, Singapore actually faced a real financial crisis in 1997, although not widely reported. The details of the bailout or restructure is not known to the public. There wasn't an Internet then so there wasn't a lot of information avenues other than IRC chatgroups and the national newspapers (in Singapore, all news is owned by the government). Before the financial crisis, there were 6 separate local banks in Singapore, POSB, DBS, OCBC, UOB, OUB and Keppel Tat Lee. After the restructure and bailout, there were only 3 banks left - DBS/POSB, OCBC and UOB. If there were another financial crisis, maybe we'll be left with 1 or 2 banks?
